$680 for the Box drivetrain? Did I hear that correctly? I can get Eagle AXS for that price at Bike-Discount. A Deore group is 149 euros. Great that there is an alternative, but at those prices it's not going to fly I'm afraid.
Be honest 680 only gets you an AXS derailleur and shifter. The cassette is anothe 180$. For box, 680$ gets you their nicest shifter and derailleur and their Gucci 1 piece cassette. The budget model was around 250 in the previous iteration. I’d imagine the new mode will be similar. The one piece cassette on the first gen was somewhere around 350g. That’s XTR /XO territory. The quality of their shifter on the previous 11 speed has kept me away though. The original single lever shifter worked great but the two lever shifter I ended up blowing up two on their first rides. I wound up just running a Shimano shifter which worked fine. I do wonder if I can get the cassette to play nice with my advent shifter/derailleur. Gx AXS on my other bike is also flawless for informing my biases.
@gotohe11carolina: Not apples to apples but I liked the jumps on the Box3 9 speed cassette to replace the Microshift cassette that I bent on a bad shift. The shifting worked well with the Advent shifter and derailleur. I was having trouble with a standard 9 speed chain and those problems were fixed by getting a Box Prime9 chain.
It sounds like this video says a standard 9 speed chain is supposed to work on the new Box1.
Comparing the Prime9 chain to a standard 9 speed chain. It looks to me that there were flared recesses on the outer links on the Prime9.
@gotohe11carolina: yeah, sometimes the big online German shops sell items cheaper than what the LBS here in NL pays wholesale. The bicycle industry is weird like that.
Only 10 of us yelling for 20mm eh?! There are literally dozens of us! You watch, 20 mil front axles are going to rise from the ashes when we finally realize you can make perfectly pedal-able dual-crown 190mm+ wince & plummet sporting equipment built for athletes.
I give it a from now... egg, en-route, through the headset of your wife's boyfriend's motorized bicycle, straight to the face.
20mm axles will be back... its an inevitability IMO because we are seeing more upside-down forks, which benefit immensely from the torsional rigidity that thick axles provide.
Seems a bit unnecessary on traditional forks, they're pretty rigid these days. I'd be very surprised if there was a discernable difference between a 15mm axle modern enduro fork and a 20mm axled one.
It'll come back, but it'll be 20mm x 120mm, with a slightly positive offset for the disc, you know even spoke tension and all that.....Makes it tough to re-purpose your old CK front hub
I used to agree with you, and wanted a Bartlett style dual crown enduro fork.... but the 190mm single crown Zeb is 3/4 pound lighter than a Boxxer, and again they are being used in Rampage now...
@ryanandrewrogers: Doubt that dual crowns will be mainstream. The issues is that no pro is going to like them, because they ultimately feel different and weigh more, which means sacrificing time to adapt to them and being slower. Because mtb market pretty much runs on advertising, consumers are not going to buy them, even though the advantages of usd forks are better for the recreational rider.
Also, USD forks need more accurate machining, so seals don't pop out and leak fluid all over your rotor. Bike industry isn't exactly known for accuracy.
@8a71b4: I'm saying 20mm axles for single crowns will be coming back because of USD forks.
I didn't really want the heat of the dual vs single crown debate but IMO it would just take a little bit of development to make a dual crown as uphill able as the modern Zeb/38. The Zeb is hardly even a half-pound lighter than the Boxxer Ultimate (meaning the Zeb is closer in weight to a Boxxer than to a Lyrik ). You're right that dual crowns won't be mainstream too soon, but I don't think it's because of the racers. I think it looks too weird and people wouldn't buy it.
The current generation 38mm enduro forks occupy a stupid middle ground right now, with dual-crown weight and single-crown performance. Something has to give soon, right? Either dual crowns or USD first, but I reckon both eventually because the two work best together.
@ryanandrewrogers: There is a 300 gram difference between the Zeb and Boxxer WC according to what I've read (29er vs 29er). Is that out of date?
My armchair engineering gut-instinct does day that an inverted fork for the 150mm+ range would probably be easier to engineer as a dual crown chassis, given the torsional stiffness challenge. Really, unless you do something like the Lefty or DVO's integrated guards/bridge, the only way to get good torsional stiffness on an inverted fork is to have insane fore-aft stiffness, which prevents the two legs from flexing at different rates (the true source of torsional flex), which is easier to achieve with a DC.
@hamncheez: The difference is 268 grams using reviewed weights between the two forks both in 29", although could be somewhat inaccurate since RS is known to really mess up when it comes to putting oil in the damn things from the factory.
My armchair engineering instincts agree with yours, which is why I think 20mm axles are a must for any kind of USD, to help keep the legs flexing at the same rate.
@ryanandrewrogers: X-Fusion had their Revel inverted fork that ported over the same brass keys that dropper posts use. They never released the fork stateside (or in Europe) because it was clear what worked on droppers didn't work on suspension- the twisting forces would cause the brass keys to bind, creating massive stiction in corners and on more extreme torsional loads they just broke.
@hamncheez: Yeah, do not know why X-Fusion thought that 34mm stanchions with their little keyed system would work on an all-mountain USD fork. Attempting to mitigate twisting within each individual stanchion doesn't really translate to solving rigidity across the whole fork.
I quite like what PUSH has done here with the crown providing what appears to be a lot of torsional support for the legs. But, I have to question whether one big heavy crown is any lighter than two crowns, cause it sure as hell ain't gonna be as stiff.
@ryanandrewrogers: I think roller bearings in one leg would do the trick. Like a lefty on one side, but that begs the question why not just a lefty....
@hamncheez: You got any proof on that, or is that just your guess? I've owned my Revel for about three years now and ridden it fairly hard, I've never had any of the issues you've just said. I don't believe you.
I was hoping to see at least one photo of Henry looking like a boiled lobster.
As a fellow Brit, use a sunscreen with a minimum 50 spf rating along with a wide brimmed hat. Our pasty white skin isn't fond of the evil orange ball in the sky.
Disappointed there was no PUSH fork cycling……who brings a new product to a world class event with no details……is this supposed to stir excitement? Also, no coverage on 5-devs new titanium cranks.
@HeatedRotor: dang, I’ve had struggles with push in the past but never 5Dev! What happened? They’ve always been bend over backwards incredible towards me
@stormracing: well they've finally been called out for their less than acceptable cranks and their rude Warranty/social guy.
I had some snap on me, they said "oh mustve been a prototype set" cool, sent me anther set, they snapped when i went over a road bump on way to trail so i contacted them again, "oh, mustve been a prototype set" literally a copy and paste email - I questioned this and the guy told me to lose weight so they wouldnt keep breaking and that wasnt their problem.
now they have been abusing customers on socials and deleting comments on their posts - ie any negative ones
@HeatedRotor: dang, I’ve been out of the loop and didn’t know all that. Been great times with mine but sorry to hear that! Hope mine hold. That always blows when it turns into that stuff Appreciate the explanation on all that’s been going on!
@HeatedRotor: I've been trying to find some info or images of this issue with their cranks and haven't turned up anything. Could you send me some links? Makes me kinda worry about mine but so far I've been super hard on them with no issues.
@wburnes: damn that's shitty, I hope they world on their QC.
Though I will say from personal experience they are solid. I have mine on a chromag hardtail that's been clapped to shit so far on some jumps n drops. Don't see any signs of stress or a failure yet. I'll let you guys know if that changes but so far, I have no complaints with them.
@HeatedRotor: I struggle with this too. While I like some of their stuff, I can't bring myself to buy it after reading the lawsuits associated with 5th axis (their workholding company)
I saw the headline "budget drivetrain" and assumed we'd see things like the Sensah and L-TWOO mtb offerings, instead they show us a Box drivetrain that costs more than you can get an XT groupset for.
I've got the current gen box 1 prime 9 and it works a treat, takes a beating and keeps on going. Pretty dang ideal for a heavy-duty trail/enduro bike. That cassette isn't new, it's been on their site for ages, and I managed to get a used one once...but it was all worn out and the chain skips like crazy so I couldn't really use it. Wanted to get a replacement ever since but it's never in stock. It's mega light and all, but at this point I'm wondering if they'll ever be able to truly bring it to market beyond short production runs for marketing glitz.
I don't get the the project321 hub- it is a hub with proprietary adapter to convert it to 6 bolts. You'll still have to remove all 6 bolts to remove the disc- so why not buy a 6-bolt hub then?
The point is to give you a hub that will mount a 6-bolt rotor like a 6-boly hub (i.e. no lock ring), and, give you center-lock. A lot of 6-bolt holdouts are just that because they prefer bolts to lock-rings for various reasons.
It's also the only fix if you bodge up the lock-rings threads on a center-lock hubs, and give you redundancy where it was not available before.
Fortunately the hubs have a center lock hubshell as the baseline, so no problem.
What's cool for center lock users is that in the small chance you foul up your lock ring threads, these flanges will still allow you to ride where previously your hubs would have been toast. Infrequent issues, but for the few who see it is a big deal.
That's cool that Project 321 is accommodating those people who still hold on to that bizarre six bolt rotor fetish. Six bolt - "not that there's anything wrong with that."
sorry for being ignorant, but what's wrong with Centerlock? At least for me, it's easy to install and service, and I had no reliability issues in 3 years. Hence I voluntarily chose a centerlock wheelset for my latest build
@hardtailpunter: I personally don't care which system, I would just prefer there to be only one. Either CL, or 6 bolt. But I am already annoyed that we have XD and Microspline, so I guess we will just continue to have extra standards.
Also, 9 gears are sweeeet.
Uhhh. No. www.bike-discount.de/de/sram-gx-eagle-axs-12-fach-upgrade-kit-10-52t-1
