First Look: BikeYoke's New Suspension Saddle & Adjustable-Stroke Dropper Post

BikeYoke's Sagma saddle is cushioned slightly by a pair of elastomers which allow it to conform to your movements.


BikeYoke Divine Adjustable Dropper & Sagma Suspension Saddle

Never heard of BikeYoke? The German accessory maker got its start making upgrade suspension links for popular trail bikes and the name stuck. They really flexed their muscles, however, by solving "RockShox Reverb Syndrome" (RRS infected other brands as well), the hateful moment when air slipped past the post's IFP piston and converted your dropper into a squishy suspension component. Bike Yoke eliminated the IFP piston altogether and replaced it with a simple open-bath fluid design to solve that issue, then they added a push-button vent (now a Reverb feature, BTW) to ensure that if RRS did manage to infect your post you could be back in action with a touch of a fingertip. Far better than a lengthy wait for a factory-authorized fix. BikeYoke's Revive droppers are still industry leaders, and today they dropped two more potential winners.

Sagma Saddle

BikeYoke launches their first saddle with a special chassis molded from carbon fiber reinforced nylon that contains a pair of elastomer cushions. Saddle rails are forged aluminum, profiled like I-beams (BikeYoke calls them "H" beams) for strength. The rails measure 7 x 9 millimeters and fit standard posts. The cushions allow the saddle to rock back and forth slightly with your pelvis as you pedal as well as damp some of the vibration which normally would transfer though the saddle to your nether regions. BikeYoke offers cushions of differing hardness so you can tune to suit.
Sagma Details
• Carbon reinforced nylon shell
• "Follow" damping system traces body movements
• Hardness options for damper inserts
• Forged 2014-T6 alloy aluminum H-rails
• 135 or 142mm widths
• Slow-memory iDbeads in padding conform to rider
• Weight: NA
• MSRP: $129 USD
• Contact: BikeYoke

The unisex seat profile is offered in two widths, 130 and 142 millimeters, which are cushioned using a material injected with slow-memory-foam beads that, reportedly, conform to your anatomy. Tuned flexibility is not new to saddle design, with the most successful versions developed for performance seats coming from SQLab. The benefits have been well established, so we'll look forward to a review in the near future. Sagma saddles will retail for $129 USD and hit stores early this fall.

Adjustable stroke: Release air pressure, unscrew the seal head and clip as many 5mm spacers you need to tune BikeYoke's Divine dropper height.


BikeYoke Divine Dropper Seatpost

BikeYoke say that when designing the new Devine they figured out a way to make the Revive's venting process automatic. Better still, the design team also found ways to reduce the post's cost and weight. But, that's not all - the stroke of this problem solving post can be adjusted in five-millimeter increments by clipping plastic spacers onto the shaft under its seal head. This bit of trickery allows you, the aggressive trail rider that you are, to purchase the longest dropper post you can fit into your bike's seat tube, and then adjust its stroke to achieve the maximum drop possible with your given leg length.
Divine Dropper Details
• Adjustable stroke (5mm increments)
• No special tools required
• 30.9mm or 31.6mm diameters
• Cable actuated, air/hydraulic action
• 125, 160, 185mm stroke options
• Self evacuates trapped air from system
• Proven two-bolt clamp head
• Weight: NA
• MSRP: $289/$379 depending upon stroke and options
• Contact: BikeYoke

Why might this be important? Many riders (especially those who have recently bought into the steep seat tube angle trend) find themselves wishing for more seatpost drop, but can't trade up to the next longer post because it is too tall at full extension. Adjustable stroke droppers, like OneUp's and now BikeYoke's, allow owners to reduce their post's stroke just enough to ensure proper ride height at full extension, while enjoying the lowest possible saddle height at full drop. Divine droppers are sold with 125, 160, and 185-millimeter strokes and in both 30.9 and 31.6 millimeter diameters. MSRP ranges from $289 to $379 USD depending upon post size and whether you need a cable remote lever.

Devine droppers come with four of these spacers. That's 20mm of adjustment.

bigquotesInstallation is fairly easy and takes less than 5 minutes: Release air, remove a circlip, unscrew the seal-head, clip the spacers on the shaft, then put back together. Four, 5mm clips are included with every post, allowing a drop reduction of up to 20mm. ...We intentionally chose a slightly more involved design of travel-reduction, as we think this is the best way to ensure consistent and durable smooth function.BikeYoke PR

Divine adjustable dropper post
Both the 30.9 and 31.6mm posts have interchangeable internals, which can easily be switched if your new bike requires it.



What Do We Think?

BikeYoke has impressed us with their product's reliability, and simple-is-best ingenuity. We expect no less from the Divine dropper. An adjustable stroke is going to come on handy for many riders as steep seat tube angles shove the saddle deep into the cockpit's maneuvering zone, where it must be stowed as low as possible for the rider to function in almost any technical situation.

Will the Sagma saddle catch on? I've ridden a number of SQLab's saddles and they feature a rocking-type adjustable elastomer system as well. It works well and feels seamless, which suggests that BikeYoke's Follow system has at least as much potential. Look for reviews of both in the near future.

 The bike yoke revive is by miles the best dropper I have had (past history fox, rock shox, KS Lev). Had two years no troubles, easy self service, super smooth, smallest total length for dropper height. I ride with a group of around 15. The two of us with revive never a problem in the two years owned. Everyone else with other brands some issue including a number requiring replacement. So good.

 I find I need less drop with a steep seatpost angle - the seat goes straight down rather than on an angle. Anyone else find this?
  • 3 0
 Ha - I know what bike you're talking about! I found the opposite to be true - need more drop on the LSP to get the saddle out of the way.

 With steeper seatpost / or shifting seat forward. Pelivs gets closer to BB. To keep same leg strech, I mount the seatpost higher, hence new found space (or need) for longer dropper.

 Yes! I had a 150mm dropper post with my old bike and when I tried a Knolly (slacker STA), also with a 150mm, it wasn't enough! I bought a 185mm revive for my Knolly and it is perfect but would have been a bit long for my old bike with a steeper STA!

 @Timo82: sounds like you are moving backwards in time. From steep to slack seat tube angle
  • 1 0
 @vhdh666: Yeah I know but... broke my frame and my friend could do me a good price for a Knolly! Loved their bikes just not so much the STA.

Pretty much all the new long travel 29er are like this by the way... 76° but once up in the air it becomes 68°, what a joke!! I wanted so much a Commencal Meta am 29 and rode it for a day and the climbing position was way worst than my Warden! Not comfy at all...
  • 1 0
 @Timo82: I think vhdh is right - you are moving back in time. There’s a whole whack of new 29ers with steep actual seattube angles. Orbea Rallon, all the ibis bikes, Fezzari la Sal peak, Forbidden Druid, others can chime in with more but they’re out there and they’re much nicer to climb - particularly if you’re on a large or XL or just have long legs.
  • 1 0
 @powderturns: Yeah I rode a Rallon and that's pretty much the only one I liked with the Ripmo (only tried Process, Meta AM, Meta TR, Rallon, Megatower, Ripmo and old BC edition Instinct). I don't like/want carbon. Fezzari is nice but we can't buy those here in Canada. I don't like/want carbon anyway. I should have said ''new CHEAP long travel 29er'' because I can't afford 3500-5000$ frames! Wink

Ripmo AF and Banshee Titan or Rune are on my short list!

 They pretty much licensed the patent from Morgaw saddles.
morgaw.com

I bought one of these from their original kickstarter crowdfunding. After being way late in the shipment of their saddles they promised to use we would get one of each (road, xc and enduro). I never received the enduro one. The road shape never worked for me. The XC was actually OK and quite comfortable. You could felt the tilting but I have never been able to figure out if it improved the ride or not. You had to retighten the screws attaching the rails to the elastomere thingy every once in a while when it started squealing.

 I had a Morgaw. Mine never squeaked but I may not have had it long enough, The rocking was brilliant, I thought, but the shape didn't work for me.

 $129 is a killer price for that saddle. A simple Fizik Alliante Gamma is $119 retail. Titanium WTB Volt is $129 retail. SqLabs Active is $170 retail.

 i ride on the WTB Silverado. its a solid saddle with decent cushioning for my buttocks. my Trek came with a Bontrager Arvada saddle and it was too firm and narrow. i like wtb because i think they use an overall softer material for saddles and they have lots of colour choices and models

 Yeah but the SqLab saddles are damn good. I had lots of saddles and problems. Saddles and grips are the least parts were I want to cheap out. But that supension saddle looks also very tempting

 I have a bike yoke dropper and it's hands-down one of the best components I've ever experienced. I'm really excited for these new products. Fantastic innovation on both fronts.

 Saddle is the same as the Morgaw enduro saddle from a couple of years ago!?! Or at least it looks the same!
  • 1 0
 I own a bike yoke dropper and rate it 11/10. But I'm skeptical 'bout this "suspension seat" gambit. If you ride a hardtail and want more cushion off the back, buy a non-"performance" gel saddle (one that weighs like 400g). It'll take the edge off no problem.

 I´m the only one who wonders about the side movement?? If you have the saddle in the right height, the hips shouldn't move... that's what I've been told all these years... just ask a roadie

 Every dropper has a bit of sidemovement, but there are huge differences in how much side movement the have!

 One up dropper v2 all the way, no disrespect to bikeyoke as their post has always been well regarded or to the totally reliable (2 years no service still fine) transfer 150 I took off but I got 210mm of drop for a ridiculous price, user serviceability and excellent feel. Must be a contender for the best mtb product on the market
  • 10 3
 Have seen lots of complaints about the v2. I still havent seen any about the revive

 «user serviceability»

That's not so. There is disposable cartridge.
  • 7 0
 @Jahtaka: The post is indeed "user servicable"... You can easily perform most service jobs (lubing, changing seals, etc.) and if you need to change the cartridge you can do it yourself in 5 minutes... There's no need to send the post out for servicing!
  • 1 0
 @Mntneer: Well, here's your first! I was really happy with my revive but the stanchion got loose after something like 5-6 months of use! I think it is probably because the slack seat angle of my bike put a lot of stress on the seals, I don't know, but pretty much every 29er mid to long travel are like this and don't think everybody have this problem...

My next one will be the One Up.

 You dont sit down when it gets rowdy. Seat is not a factor. Or you are doing it wrong.

 PNW Coast dropper has 40mm (20?) of air suspension. I reckon this would be better for saving your back from those spine jankin’ judders on a HT.
  • 4 2
 @JDFF: Yes, always standing on the downhills with my hardtail. But the rocky climbs are what hurt my back. You're either just taking the impact, or constantly lifting off the saddle just enough to avoid the impact (which leads to back strain)

Some of the rough climbs by me are the biggest reason for me to consider upgrading to full suspension. If a saddle can help a little bit for a fraction of the cost of an FS bike then it sounds intriguing to me. Same with the PNW Coast dropper
