Stan’s Announces Wheels With New M-Pulse Hubs

Jan 10, 2022
by Stans NoTubes  

PRESS RELEASE: Stan's

In a world filled with chaos, division, and uncertainty, Stan’s would like you to know we’ve made a really nice set of hubs. Seriously, we went all in on this. Designed and refined over the past two years, the new M-pulse hubs combine quality materials and construction with a smarter engagement system. These new hubs won’t solve the world’s biggest problems, but they will offer years of reliable engagement and less resistance than conventional pawl and ratchet style hubs.


What’s So Special About the New Hubs?

In a word: magnets. Yes, we’re talking about the same things that power Iron Maiden’s amplifiers and let billionaires’ electric trucks tow around their rocket ships (which also use magnets). The heart of the M-pulse hub is a bombproof locking engagement system with six pawls equipped with Neodymium rare earth magnets. With 216 points of engagement, M-pulse hubs need only 1.66° of rotation to start putting power to the rear wheel. When engaged, multiple teeth on each pawl lock into a hardened steel ratchet ring while each pawl’s magnet ensures perfect alignment.

This not only lets M-pulse freehubs engage more reliably and consistently than traditional spring-based pawl designs, but also provides an even more important advantage: less friction and rotational resistance when not engaged. Less friction holding you back means more you going fast, and with less effort.

The M-pulse engagement system is based on the innovative Project 321 magnetic pawl design, and all freehub body shells, magnetic pawls, ratchet rings, spacers, and axles are manufactured at Project 321’s small-batch CNC shop in Bend, Oregon. Each M-pulse hub is then assembled entirely at Stan’s headquarters in Big Flats, New York. Machining the key M-pulse components in the U.S. and assembling the hubs ourselves in New York allows a higher degree of precision, attention to detail, and quality control.

Why Are Magnets Better?

All hubs suffer from momentum-robbing drag as you coast, but when it comes to creating the most efficient and reliable ratchet system, pulling is better than pushing. Conventional mechanical pawl springs are constantly attempting to push the pawls into the ratchet ring. Those push springs are weakest when fully extended, as the teeth of the pawl engage with the teeth of the ratchet ring, but as you coast and the teeth of the pawl disengage and move down out of the teeth of the ratchet ring, push springs compress and exert even more pushing force. This creates significant drag and friction.

Unlike these inefficient mechanical push spring systems, M-pulse hubs use the pull force of Neodymium magnets to reduce drag to the absolute minimum, while still being able to engage with reliable precision the instant you push on a pedal. Magnetic pull springs are at their strongest when the pawl is engaged and are weakest during coasting, the ideal scenario to reduce drag. Project 321’s patent pending placement of the powerful but small rare earth magnets let the pawls self-align quickly and consistently during engagement while creating a hub with almost no rotational resistance when coasting.

The M-pulse hub's six magnetic pawls and hardened steel ratchet ring are also built to outlast conventional mechanical springs, which can fatigue, lose tension, and become misaligned over time. With better durability, stronger engagement, and less drag, the M-pulse design is a better way to build a hub.

More Than Just Smart

Because an innovative design is only as good as its materials and construction, each detail of the M-pulse hub has been engineered to systematically eliminate weaknesses found in traditional pawl and ratchet style hubs. The new M-pulse hub starts with the most simple and durable version of Project 321’s magnetic pawls, and features an all new freehub body and main seal design for outstanding protection from the elements. Every bearing on the M-pulse hub is shielded, meaning no bearing seal is directly exposed, for smooth rolling in all conditions and increased bearing life. The 17mm axles are made of 7075 aluminum and roll on long-lasting Enduro brand bearings that feature custom-tuned grease fills that reduce resistance. A double-row main freehub bearing was chosen after tests proved it to be more durable than two individual, separate bearings. Multiple teeth on each pawl provide a greater surface area to distribute load to improve engagement, and the angle of the pawls was optimized to distribute stress away from the rotating bearings for added durability under high torque.

Beyond the strength and speed of engagement, M-pulse hubs feature adjustable preload that decreases drag and resistance for less effort and more speed. Adjustable preload also prolongs bearing life by allowing the hub's bearing tension to be tuned with greater precision in contrast with most hubs that tension unevenly by relying solely on how much the bike’s axle has been tightened. A precision piece of equipment deserves the option of precise tuning, and the M-pulse hub's adjustable preload, available on both the front and the rear hub, delivers that level of tuning precision.

With their quality materials and construction, M-pulse hubs are backed by a 5-year warranty.

The Perfect Match for MK4 Asymmetric Rims

M-pulse hubs are available as complete wheelsets (MSRP starting at $965) laced to the MK4 asymmetric rims, including the 30mm wide Flow MK4, 28mm wide Arch MK4, and 25mm wide Crest MK4 that were all launched last summer. With flanges optimized to better balance spoke tension on each side of the rim, M-pulse hubs allow a single spoke length to be used for an entire matched MK4 wheelset. When it comes to ease of maintenance, nothing beats being able to use the same spoke length for every repair. All wheels continue to rely on traditional J-bend spokes, the most commonly available spokes that are easy to find, should you ever need a replacement.

Real World Tested


A Crest MK4 wheelset featuring the new M-pulse hub was put through the wringer when it went out on a 303 mile, 30+ hour ride. Will Loevner, a name that's becoming synonymous with ultra endurance challenges, rode the Wilderness 101 lap, a 101 mile endurance race, three consecutive times. The loop features classic East Coast single track and proved to be no challenge for the new hubs.

bigquotesOverall I was amazed to not get a single flat tire during the 303 miles. I still can’t believe how well the Crest MK4 wheels held up over what must have been a million rocks by the end of the ride. -Will Loevner

Additional Information

All carbon CB7 and the Podium SRD series wheelsets will also roll on the new M-pulse hubs.

However, M-pulse hubs will not be available on the downhill and enduro-ready Flow EX3 and on the more affordable S2 series wheels. Both are built with the E-sync hubs introduced last June.

M-pulse hub options include Shimano Micro Spline, HG, or SRAM XDR freehubs, in 6-bolt or Centerlock brake style, and configurations to fit all popular through-axle widths.

All wheelsets equipped with M-pulse hubs are also part of the Stan's Connection Program. With each wheelset registration, we’ll donate $10 to support the local trail group or cycling-related charitable organization of your choice.

 You know those products that leave such a bad taste in your mouth that you'd never even consider them again, regardless of any updates? My list starts with Reverb and Stans hubs.

 Yes, f*ck reverb. I’ve had good experiences with Stan’s wheels with Neo hubs though.

 Reverb particularly. The AXS might be super sweet, but never again with Reverbs for me. I have never tried Stan's hubs
  • 46 3
 What about Reverb AXS? Seems like it's been performing well for everyone I know.

P321 hubs are phenomenal. I think Stan's got this collaboration right.

 @bman33: I agree reverb still sucks they just won't let go of that terrible design

 Agree about the reverb, I had one as apparently it was the most reliable post at the time (2015), It was a new design that supposedly stopped them going saggy, but after 12 months mine was already sagging, and the process to bleed the thing is a PITA, cables work perfectly fine for dropper posts, we don't use hydraulics on our gears right? Got a OneUp now and it's so much simpler, has a long drop and low stack

 @Ktron: Yep I had a B2. Does the post still extend if you lift the bike by the seat when the post is dropped? apparently that's what killed a lot of reverbs. Probably what made mine sag too, lifted the bike by the seat when the post was dropped

 @gtill9000: waste people's money and precious ride time with junk products and that's what ya get.

 @jpcars10s: and not really stand behind the junk they knew they wrapped their name around. I’m not entirely sure Stan’s actually produced any of their previous hubs, I imagine the hubs/free hubs were manufactured by someone else, similar to this.
Somehow Stan’s has been able to weather this storm, as I think there rims are an excellent product.
I’m assuming Stan’s and P321 are making it known that these are essentially P321 units, and the cost savings comes from the assembly by Stan’s (I still think these cost out to be more expensive than having P321 just build you a wheel to a Stans rim, which they have always been able to do)

 Ohh, don't be so negative, try and be a little positive. But I'm hearing you on the reverb.
  • 2 0
 @rrolly: But it's still a hydraulic line to operate the post which is a pain in my experience, it's fiddly and you have to bleed it like 4 times for it to actually make the post come back at a decent speed. Cable is fine for droppers, you aren't putting huge amount of force through the cable to no risk of stretching really

 @melonhead1145: My first Reverb was terrible initially. I sent it off for warranty repair within a week of purchasing. One month after I got it back it started to sag again. So I brought it to my LBS and one of the guys there rebuilt it. It lasted four years after that without a glitch. My new Reverb has been great. Zero fiddling, other than trying the burp valve for kicks.
  • 1 0
 @melonhead1145: One benefit of hydraulic is that it works better with crazy cable bend angles, but that’s less of a problem with modern bikes designed for droppers.
  • 1 0
 @senorbanana: That's what happens when the seat tube bore is either off-size, not straight, or uses a poor clamp design. The Reverb is overbuilt so it can cope better--sometimes. Lo g and heavy for same travel though. No internal parts available for AXS posts.

 It is amusing to see all these component companies redesign and spruk their ratchet hubs when what they really want was achieved by Onyx a fair while ago.
  • 19 3
 While Onyx hubs are fantastic, I don't think companies like P321 intended to achieve the same thing as Onyx at all, while they do offer similar benefits. The nice things about P321, is they give you options for quiet and very low drag, or, loud and just marginally more drag. You can have Onyx-ish performance, or I9-ish performance, in a completely unique looking package. P321 hubs are some of the best looking hubs out there to boot, and really nicely machined hub shells. Options are great to have!

 @privateer-wheels: My experience with Onyx was that I quickly switched back to a pawl/ratchet design. I found them to have a very "soft" feel when engaging (like power was being lost) and they never felt as good as my 5 year old Torch hubs. I also didn't particularly like having to "preload" my hub bearings. Each to their own, but I can't think of a hub I've owned in the last 25 years where I immediately wanted it off my bike.
  • 2 0
 @fluider: Oh yes, Box' Stealth! I've read quite a bit about it when it was press released, but basically nothing after that. Interestingly, their hub weights 500g, but people are bashing Onyx (414g). Apparently it ain't that easy to produce a silent hub with low drag, quick engagement AND low weight.

I wonder why Shimano ditched their silent hub...
  • 2 0
 @Zayphod: As far as I know Shimano used roller clutch as well many many years ago, just like True Precision/BOX, but of even smaller dimensions (torque capacity) than BOX and they implemented it wrongly. Roller or sprag clutch requires steel material on the parts in coupling, hence the higher weight.

 @fluider: my left non-drive main bearing completely seized, and the freehub XD bearing seized as well. Within 4 months of riding. I have since replaced them with Phil woods bearings from nsk. Onyx doesn't even seem to trust their own ceramic bearings due to their 1 month warranty on them.

 @privateer-wheels: the quiet pawls haven't been available to actually buy for awhile now, and have no estimated restock time. So there really isn't options, currently.

 @foggnm: I hear that often enough, that some people don't like the soft pickup, when the tangs stand and cam on the axle. You will not get the firm "clang" you do with a pawl and tooth hub, but I don't think you lose much in way of power.

Bearing preload on the other hand, is actually not a bad thing. Many other high end hubs like Chris King and Hadely for example, require you to preload the bearing because they use angular contact style bearings. when properly preloaded, they will handle side loading better than a standard radial bearing. But, the owner has to pay attention to that, and riding them with slack will ruin your bearing. I've never Found Onyx or CK need much of any adjustment after the first couple of rides.

But I agree, to each their own. Fortunately there are lots of great options!

 No way. I've had two sets of 321 hubs and between the skipping engagement and magnets detaching from the pawls, there's no way I'd ever get another set. The customer service people at 321 were super nice and responsive, but either the design or the manufacuring of the hubs that I had sucked.

 How long since you had them? They warranties my pawls and updated the design, no issues since

 That must have been a long time ago. The current design is bulletproof. P321 hubs are the most reliable I have ever owned.

 Ive had 2 sets of 321 magnet rear hubs $hit the bed. One had the magnets fall off the pawls they replaced the free hub body and the pawls then a pawl broke in two and the entire inside of the hub was destroyed. They then gave me a new hub it had no set screw on the axle end cap and loosened the freehub body enough to come apart and self destruct on the trail. The third held up for a little over a year before i before I replaced it with a hub I trusted more. I agree they where super nice and helpfull at 321 though. The axle never broke like a stans hub.

 As if freehub drag is an issue. Give a small push to any rear wheel and it will rotate for a while if you take out any other sources of friction (ground, chain, dragging brakes, bad bearings), and you can stop it with a single finger.
  • 6 1
 I accelerate when I roll down hills. The drag can't be that bad.
  • 3 0
 I understand too little about this part of physics, but if these magnets spin circles does that create a flux through the axle? Does that imply that when the hub gets wet, one end will vent oxygen and the other will vent hydrogen? Or, as my frame is steel, will it just attract metals and charge and attract dust? I don't care enough about rolling resistance but I want to know to recognize those who ride with these hubs.

 Cool, but I ride bmx and magnet hubs have existed for a while in bmx with tons of problems. I guess we will see if they work well, no judgement so far like all the keyboard warriors in this comment section.

 With the magnets constantly pulling the pawls against the tooth ring, common sense would suggest that would create the same if not more friction when coasting than a traditional setup.
  • 1 0
 According to the marketing article there is less drag because when the pawl is extended during coasting i.e. tip of pawl teeth touching engagement teeth the magnet is weakest so less drag. Where as the traditional spring this is the opposite and the spring is pushing more at this point. Its surely a laughable amount of drag saved. I would love to see actual measurable results comparing the two.

 Are pawl springs unreliable? I would be surprised if hub brands didn't design their springs with a fatigue life longer than a bike frame.

 I have overcome the drag of my regular old hubs with springs in them by having even larger magnets and a battery attached to my bike. These magnets works shockingly well, even if not in the hubs.

 Neo-dy-mi-um. Neodymium anybody else strugle w/that
I use these magnets at work to mount GPS recvr components to the inside of heavy equipment cabs and they’re no joke first time I tried to attach one my fingers were smashed between the rec and the machine like instantly it sucked they’re strong as sh%10-4
Id like to never got my flangies bk .anybody know if the other side of each magnet is magnetic to the pawl its mounted in or is it tryin to push itself out like two magnets put together? If so that seems like a prob waiting to happen?
  • 1 0
 The pawl is normal tool steel. The magnets are held in by their own attraction to the pawl. Once attached they cause the pawl to become magnetized which attracts it to the steel drive ring. I've been running Project321 hubs on my hardtail for over a year and the system works brilliantly.

 Why is there no mention of the hub weight? I’m guessing it’s pretty heavy. By intentionally omitting the weight, it seems pretty obvious they don’t want people to know how heavy it is.

 The website has total wheel weight and they seem competitive, maybe not DT180, but not anchors either.

 The difference in drag (measure in watts) between pawls, ratchet drivers, and sprague clutches is negligible. An aggressive free hub body seal will cause more drag. That said, I had good luck with the P321 hubs. Just be sure to maintain them. A couple of magnets came off the pawls and were crushed into magnetized metal filings, which was a bit of work to remove.

 It also looks like a better placement for the magnets....but I guess they're pushing not pulling....so some guy says that's worse....who knows...
  • 1 0
 @takeiteasyridehard: In the pushing configuration, magnetic force drops exponentially as pawls engage. It's actually worse than a conventional spring (where the force decrease is only linear). In the pulling configuration it increases exponentially as pawls engage.
  • 1 0
 @Kopsis: Thanks for pointing that out. I wasnt thinking about that at the time. I wonder if the force of the spring/magnet, whatever it may be, is more important at starting engagement versus keeping them fully engaged....it seems like the mechanical aspect of the drive forces wedging the pawls into place on the drive ring would overcome and bind the pawls in engagement much stronger than the magnet, effectively making the magnets strength during full engagement irrelevant. It would have the reduced drag benefits while coasting, but I also feel like the magnets are much less likely to separate from the pawls on the kappius design. It seems to me that reduced drag might be the only practical benefit in the real world, but it comes with potential magnet separation. But idk...I suppose a lot of lab tests with cutaways to see their influence on engagement would be needed.

 I just worry they would attract metal shavings and grit. Love stans rims so nice to see them offer some decent hubs, but the set I built with Mark 4 flows on xt hubs and dt butted spokes is more bang for buck in my opinion.

 DTswiss should make a ratchet set with attracting magnetic pieces. Win-win-win (less drag + stronger and non-degrading engagemang - should work well with the new 1movable Ratchet system - DTswiss quality).

 I'm curious as to how long the magnetism will last being put through these extremely variable conditions? Have they been tested in cold cold weather? Magnets lose their magnetism in cold weather as well.

 I've had the Project321 hubs since they first started using magnetic pawls, about 5 years I think.... there has been no degradation on freehub function, and I ride in below freezing temperatures regularly. Not to mention ZIPP have been using magnetic freehubs even longer.

 If I'm paying top dollar for a quality product, why would I want Stans name on it? I'll just buy the P321 branded hubs and have my wheels custom built. Then at least there will be some resale value.

 Does anyone think that magnets are still as reliable as a spring I am curious to know how well they work with thick grease
  • 3 0
 I’d use Dumonde Tech freehub oil, stays slick much longer anyway and takes very little.
  • 5 0
 Why the need for a thick grease? Given the fact they will likely be a quiet hub, you would probably be best serves using a light grease.

P321 has both loud and quiet configurations, so no need to fuss too much trying to use thick grease that will bog the hub down. Just use super slippery Dumonde grease or oil as DiryMcLeod has noted.

Otherwise, the magnets in P321 have been perfectly reliable for the wheels I have built.
  • 1 0
 @dirtmcleod: agreed, and typically not supposed to use thick grease on free hubs (unless cup & cone), from my experience.
@healthy-not-sick-biker definitely do NOT use thick grease on magnetic pawled hubs. Will lead to a faceplant when you try and lay down some watts. Wink

 I thought the whole deal with metal springs is that they are linear. This is kinda saying the opposite....
  • 2 0
 They INCREASE linearly as they compress. They do not exert the same force throughout the stroke. Now the force curve of an air sprung pawl would be even worse than the metal spring because it has a positive ramp. But magnets have a negative force curve in this application, exerting less force as the pawl is pressed by the ratchet tooth.
  • 1 0
 linear slope. from 0 at full relaxed position to max force at max compression in a straight line slope. But it's not "linear" constant force with slope=0.

Magnetic pulling force can be considered progressive. Light at relaxed state, then ramp up really high when it's close.

What part is "opposite"?
