BikeYoke, the maker of that slippery-smooth Revive dropper post, has just sent us information about a new, bigger version of the Revive. Called the Revive Max (we’ll save you the shouting by writing it without capitals), this dropper post is purpose built for an emerging trend of 34.9mm diameter seat tubes.
Scott used to use a 34.9mm diameter seat tubes for the superlight Scale hardtail and Spark full suspension race bikes, but it was mostly for weight purposes, not for running a dropper. More recently, GT has made use of 34.9mm seat tubes on its Force model, while Liteville has elected for an oversized seat tube in order to offer the Eightpins integrated dropper post system, citing the bigger diameter 34.9mm diameter could offer up more space inside to fit in a durable and strong mechanism that can offer more overall drop.
A much newer and more mainstream bike that is also using a 34.9mm diameter seatpost is the 2017 and 2018 Specialized Enduro. The reason behind this move is that Specialized is making its own 34.9mm dropper post called the Command WU. We actually reviewed the WU dropper last week, and while its unique tilting action is novel, we couldn’t help but wonder if Specialized could have just made a regular dropper post with more travel.
Well, looks like BikeYoke has beaten them to the punch.
Well, technically the RockShox Reverb has beaten BikeYoke to the punch. The Reverb is already available in a 34.9mm diameter and with up to 170mm of travel. However, BikeYoke has gone one further with its design, offering up to a huge 185mm of travel!
Designed for 34.9mm frames, the Revive Max obviously features a larger diameter for the main outer tube. But BikeYoke says it is unique in that it features a proportionally bigger stanchion (28mm diameter on Revive Max vs 25mm on the standard Revive posts), which means not only is it stiffer and stronger, there’s also more room for all the guts inside.
The punt that BikeYoke is taking, is that Specialized is likely to filter the 34.9mm diameter seatpost throughout its range, potentially with the next Stumpjumper model. And if Specialized do that, other bike companies are likely to take even more notice. Dropper posts are great tools, and more frame designers are electing to use shorter seat tubes so that they can fit longer travel dropper posts. But that can put a lot of stress on both the dropper and the frame. A larger diameter seat tube however, frees up the ability to build a stronger, stiffer and more robust dropper post while still getting that extra long stroke.
As for the post itself? Well we haven’t used one yet – it’s brand new. We tested and reviewed the BikeYoke Revive dropper post last year, and were particularly impressed with its uber smooth action and low overall stack height. The post did have a bit of an issue with the Revive function, though we’ve been assured has been sorted on the second generation. We’ll be getting one of the new 185mm travel Revive droppers in soon for testing, so stay tuned for that review.
In the meantime, here’s the entire press release from BikeYoke;
World´s first dedicated 34.9 dropper post with up to 185mm drop
Why bother with a shim-adapted dropper post in a high end frame like the new Specialized Enduro, EVIL Wreckoning, Pyga Hyrax or Slakline, Liteville and the likes?
One should not forget, that many more bikes with 34.9mm seat tubes are not unlikely to come, since – yes, undoubtedly – especially E-Bikes with more critical requirements in terms of legal testing reports will greatly benefit from the strength gain.
Until now there was no dedicated 34.9 dropper post available, that had various travel options with up to 185mm of travel. While there have been some brands with 34.9 options, all of them based on their regular sized siblings with original upper tube diameter. Means: Those droppers just used a bigger lower tube and kept the general design unchanged.
More space inside the seat tube comes along with huge possibilities to make the post stronger, stiffer, smoother, but other post designs fail to take advantage of those circumstances. However, the biggest design flaw – in our opinion – is, that those small/regular upper tubes would not really want to match with the oversized seat tubes. A bike of this price range deserves a properly designed and looking post. Period.
To be fair: There is one dedicated 34.9 post with an oversized upper tube, Specialized´s newest creation. However, this post only offers 115mm of tube 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 25mm), optimized wall thicknesses, increased bushing strength, while keeping the market´s shortest stack height and extremely low overall length/ travel ratio as it 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, considering, 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.
- 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
REVIVE MAX will start shipping by middle of March to our dealers and distributors and end consumers.
