BikeYoke Revive Max - World's First Dedicated 34.9mm Long-Travel Dropper

Jan 26, 2018

PRESS RELEASE: BikeYoke

REVIVE MAX S-Works 2


BikeYoke Revive Max Dropper Seatpost

Long story short: here is no rocket science involved, no spaceship materials used, and we did not reinvent the wheel or want to make up fancy stories. We simply came up with a really long-travel dropper seatpost, completely designed and engineered for the beefy, 34.9mm seat tubes that are appearing on a number of bikes. Until now, there was no dedicated 34.9mm dropper post available with travel options up to 185mm. While there have been some brands with 34.9 options, all of them are based on their regular sized siblings, but with original upper tube diameter. That means that those droppers just used a bigger lower tube and kept the general design unchanged.
Revive Max Details:

• Same features as regular Revive
• Stronger than a regular Reviv
• A little bit heavier than a normal Revive, but lighter than many 30.9 and 31.6mm competitors
• Weights: 125/34.9: 530g; 160/34.9: 590g; 185/34.9: 630g
• MSRP (including Triggy remote): 125/34.9: $455 USD; 160/34.9: $479 USD; 185/34.9: $499 USD

We think that you'd be better served with a dedicated 34.9mm dropper instead of using a shim-adapted post for your high-end frame, like the new Specialized Enduro, Evil Wreckoning, Pyga Hyrax or Slakline and Liteville. Many more bikes with 34.9mm seat tubes are on the way, as frames are being made lower to use longer droppers and therefore need to be stiffer and stronger.


REVIVE MAX vs. REVIVE


More space inside the seat tube comes along with huge possibilities to make the post stronger, stiffer, and smoother, but other post designs fail to take advantage of those circumstances. However, the biggest design flaw (in our opinion) is that those small upper tubes do not really match with the oversized seat tubes. A bike of this price range deserves a properly designed and good looking post, period. To be fair, there is one dedicated 34.9mm post with an oversized upper tube: Specialized´s newest creation. However, this post only offers 115mm of travel.

BikeYoke now proudly presents the world´s first dedicated 34.9 dropper post, which was solely and completely designed for the oversized seat tubes. Revive Max features a 28mm stanchion (original Revive is 25mm), optimized wall thicknesses, and increased bushing strength, all while keeping the market´s shortest stack height and extremely low overall length for each travel option, as is already featured by its smaller Revive siblings. This minimizes the weight penalty to less than 50g compared to a (160/31.6), resulting in a total weight of 590g for the post only, which is still lower than many competitors with less travel and smaller diameter. One should not forget that the added weight is even less when you consider that there is no more need for an extra shim inside the seat tube.Of course, all Revive Max will come with the latest revision of our patented instant reset function and integrated quick-reset lever.

NEW I-Spec Options for Remote Handlebar Mounting

Another nice feature of our Revive is the possibility to attach the Triggy remote directly to SRAM, Magura, Hope, and Formula brake perches via their specific direct mount options (e.g. SRAM Matchmaker, Magura Shitmix, Formula Mixmaster and others). Our Triggy uses the same interface as SRAM triggers, which means that you can mount it directly to any Matchmaker compatible brake lever. Shimano brake levers can be mated with BikeYoke´s I-Spec adapters, which are available for left (Triggy) and right side (SRAM Trigger) to get rid of an extra clamp and keep the cockpit clean.

 The 9point8 34.9 droppers are still lighter and offer more travel.

Bike Yoke 160mm travel 590g post only
9point8 175mm travel 589g post only

Bike Yoke 185mm travel 630g post only
9point8 200mm travel 638g post only (8g heavier for 15mm more travel)

However what is more important to me is the insertion length of these posts. That is something I would be interested to see comparatively since from what I've seen, all the 34.9 bikes don't leave much for post insertion depth.
  • 16 1
 Yes, 9Point8 is a bit lighter, yet they don´t feature the bigger upper tube diameter.
About the lengths:
Why don´t you just check our website for the length? All measurements can be found under dimensions and weight:
www.bikeyoke.de/en/seatpost-revive-MAX-185-349.html
9Point8 also offers length drawings:

Edit: From looking on the forums, looks like the first revised seals were being used in warrant repairs around December 20th.

 @bcatt: I've been using the revive since two years. To make it short, best dropper money can buy. Had kind shocks, Reverbs and the fox dropper, they all worked well in the beginning, but could not hold that performance for too long. Even if the design of the bikeyoke has some issues such as the fact that the air camber isn't separated like on other droppers (it's actually their feature) which requires that you need to reset the dropper from time to time (takes less than 10 seconds)
My revive still has no play, never had any problems, the trigger and actuation is flawless and it runs as smoothly as Usain Bolt.
If it happens that my next dream bike has a funky sized seat tube diameter, I'll check first if bikeyoke offers that size before I would buy the frame.

 @x-rider: Wow, checking the compatibility of your frame with our dropper is a bold statement, but it honors us. However, I´d be surprised, if you had been on our REVIVE for two years, already. We started delivering the first ones about almost exactly one year ago, in January 2017. I have had another customer this week, who just said exactly the same thing. How come you all think you´ve been on a REVIVE for two years? ;-)

 @x-rider: I-Spec adapters are always in stock at us directly, not sure about Reverse. I´ve sent them a couple like a week ago. Reverse only sells to dealers, though.

 Of all the "standard's" changes we've seen in the last couple years, this and 157mm hubs are the ones most likely to make a real difference in the progression of trail bikes. No half steps, no bullshit, just the gods honest truth that in some circumstances with some bikes stiffness hasn't kept up with development.
Since Sakki is still making other seatpost sizes, there is nothing to be upset about here. He's simply taking a bit of risk while doing us all a massive favor. If your frame company of choice decides to use a seat tube diameter that's appropriate for long travel droppers, now you have a solid option for a post to use.
3 years from now this will look like a much more logical progression than Boost.

 Yah. This is well thought out
  • 8 4
 Ah, finally someone does it! It always struck me how dropper posts were dimensioned around frames dimensioned around rigid seatposts. But with rigid seatposts the actual seatpost diameter is the critical dimension whereas with dropper posts it is the stanchion diameter. I'm sure we're not done yet. Everyone seems to be using Fox stanchions for stuff so I'm sure soon enough seatpost stanchion diameters will come in 32mm, 34mm, 36mm and 40mm.

 It's really odd that now when even XC bikes come with dropper post and beefy tubes that the seat tubes are so skinny compared to the rest of the bike. On my Switchblade, down tube is 4x the size, top tube 2x the size and even chainstays and seatstays are close to the seat tube size. It makes no sense especially on FS bikes with all those pivots punching through.
  • 5 0
 Skinny seat tubes make sence in XC, because 27.2 carbon seatpost adds some flex and it is said to be more comfortable . Maybe it's due to punishing stiffness of high-end XC machines. Never ridden one, so can't say for sure.

 Already running the shimmed version on my Evil and I love it. Wish 34.9 had been available when I bought it, hopefully the new one is a bit stiffer at full extension. I also find the lever a bit short and the mount is not very sturdy with i-spec, hopefully that's been upgraded as well.

 Similar case with me and my 2012 Scott Genius 50. If I ever get this post, have to figure out a way to get the cable inside the frame which has no designed entry orifice.
  • 2 0
 @Corrado0329: I have a Scott Spark that had cable routing for a front derailluer. It had a cable stop in the frame designed to run a cable without housing, and I just drilled it out to run housing for the dropper. Otherwise you might consider drilling a hole in the seat tube.
  • 1 0
 @dthomp325: Thanks for your comment! I am going to perform your suggested method on my other bike (Cannondale Jekyll 2013), which has exactly the same cable routing as your Scott Spark. As per my Scott Genius, the drilling process seems like my only choice. Good info!

 Love this! However I’d gladly exchange post travel for bushing overlap. One day I’ll order a custom 26” ht which will basically be a dj bike that can ride in the woods. It will have a dropper like this Big Grin

Congratulations @Sacki

 Who's using a shim on their Wreckoning? I bought one of the first XLs two years ago and bought a 34.9 175mm Reverb to go with it. What's the big deal? And there's been 9point8s available for almost as long, and in 200mm drop. Sure these posts just stuff the existing internals into a bigger outer tube but you know what that affects? Nothing it turns out. I run my post at the minimum insertion line and my 220lbs hasn't caused the Reverb any strife.
  • 2 0
 I use a Revive + shim on my Wreckoning.

I originally installed a Reverb B2, but it was just so awful: slow extension, stiction compression, un-ergonomic lever, difficult to remove from the bike, and to top it all off ruined a race for me after I forgot to put the seat up before handing it to the hotel valet. I'm sure the valet innocently hung it by the seat, and then it didn't work properly the next day. Also don't forget to put that seat up before you hand the bike off to the guy in the back of the shuttle truck, or put it in a bike stand, or wash it, or f*cking look at it funny. Ugh, what a stupid design, a 1/2 second of forgetfulness to put your seat up should not risk ruining your race/trip/weekend.

I warrantied that Reverb and sold that shit on ebay right quick. I don't think 9point8 34.9 was available yet when I ditched my Reverb, but it looks like a much better design. I've been very happy with my Revive, the engineering design is far superior to an IFP. It's super solid and my only complaint is the lever is a bit short and flexy when mounted to i-spec.

 Great Product but for a rather limited audience.

Your Liteville comes with an 8 Pins which is a masterpiece in terms of weight, function and reliability.
Your specialized comes with a WU which is at least reliable and tilts your saddle. Neat feature.

BTW - both mentioned posts are 34,9mm only. Both posts are expensive as f*ck, at least in Germany.
Therefore - we have a market for the revive.

People who own very expensive 34,9mm seattube bikes who dont already have one of the listed seatposts and dont want to slash out the money for either of those! (older litevilles, older enduros). It shares this market with... ...everyone else, including Point8, Vecnum and the rest. Good luck.

well year later, and mine leaks and is NOT user serviceable (unlike prev command post I changed 2 broken collette and serviced) and neither can the shop get the seal kit. Have to send it in... for close to the price (and being ehtout a seat post for couple weeks) I can get a brand new other brand one... no way..
I do like the tilt, but it's not really 150mm drop (115mm+tilt). Wish it was more...

 They did and we even credited this in our press-release. However, the WU-Post only has 115mm of tube movement + tilt.
  • 3 5
 @Sacki: Although it might be true how it is stated, the difference between the bikeyoke and the WU post now seem higher than it is. The WU post effective drop is 150mm, which would be a more honoust comparison
  • 17 1
 @Kjell: Well, I don´t want to be pettyfogging, but how would you be able to clearly state, that the "effective" drop is 150mm on the WU-Post? The "effective" drop greatly depends on where on the saddle the effectiv drop is referenced. The highest effective drop on the WU-post will be at the rear tip of the saddle. If you measure somewhere else, the effective drop will be different. Then it also depends on how long your saddle is, and at which horizontal position it is installed. I have no idea about the WU-post´s real "effective" drop, because it is simply not easy to give an absolute correct drop dimension. All I can say is, that the tube moves 115mm. The effective drop could be more or less than 150mm, but I would want to assume (not saying, that I am correct here), that the 150mm might be measured in the most favorable way, as every manufacturer would claim its own features - just as we do it, too!

 @dthomp325: Specialized really does make some reliable droppers, no doubt! It´s just a shame, they don´t offer more drop. This and the fact, that they have an offset reduces the number of potential customers a lot.Other than that I think they are really good posts.
  • 2 0
 @Sacki: The Problem with the WU ist the height of the tilting mechanism which limits travel if you dont make a dropper that is 50cm long. Also, there is noticable play on the tilting mechanism.

However, when you nedd a little setback on the post the drop increases conciderably and when you need to lower yourself on the bike its very comfortable due to the saddle tilt and the play is not noticable when you ride the bike.

On other posts 115mm of travel feels limiting, on the WU it somehow does not.

Best Regards,

Stefan

 Don't plan to use this post unless you have a L or XL Enduro because there's not much insertion. I tried to install a 160mm post on my M Enduro and no dice!

 That's definitely on Specialized. Been a problem with the design from day one. Small frames can only take a 75mm dropper for most people. Not exactly "enduro" friendly. Curved seat tubes and pass through linkage bolts might look good for marketing, but they suck for modern mountain bike design.
