With simply 80mm of journey, BikeYoke has scaled again their most-popular, never-spongy Revive dropper seatpost to 27.2mm within the new Revive 272 – admitting that they’ve given in to the peer stress of the gravel growth. Now, adventurous gravel and even hold-out cross-country riders with 27.2 posts and stealth inner routing can profit from dropping their saddle when the going will get tough, with out the fear of putting in a dropper solely to undergo the bouncy destiny of a failed IFP with air inside.
We examined it out, and break down the ups & downs…
BikeYoke Revive 272, 80mm journey 27.2mm gravel dropper put up
Apparently since day 1 with the unique Revive dropper – a distant 6.5 years in the past – prospects have been pestering BikeYoke for a 27.2mm model, actually predating the gravel explosion. However BikeYoke continued to withstand, as it’s simply extremely tough to suit their advanced, long-life hydraulics inside such a small area.
Effectively, trendy XC bikes moved to 30.9 & 31.6mm posts, however loads of gravel bikes caught with the OG seatpost measurement – whether or not for conventional small diameter appears or the added consolation advantage of the higher flex traits of a smaller diameter cylinder. And now loopy gravel cyclists are driving their gravel bikes like mountain bikes – clearly on MTB-friendly singletrack, but additionally underbiking or down-graveling much more technical trails.
So, BikeYoke sucked it up and spent the time and R&D effort into squeezing their Revive tech right into a 27.2mm dropper.
Wait, what’s so particular a few Revive dropper once more?
Let’s return in time 6 years to recollect: the important thing to a Revive dropper is the distinctive patented configuration of its inner hydraulics that enables it to be reset, or primarily re-bled, when air bubbles invariably sneak previous the flexing inner seals as your weight flexes the put up. This widespread cavitation of the sealed IFP that happens in most hydraulic dropper posts makes the put up squish, and requires a substitute inner piston in most/many instances.
The Revive is just revived by turning that bolt on the high (with a 4mm hex or the included min-lever on newer posts), pushing down on the put up to let the air up and the oil again down. Then, releasing and going again to good drops and no squish on the high of extension.
So, what’s truly new?
The diameter & drop are the true new bits on the surface. The Revive 272 dropper is 27.2mm in diameter, and incorporates a brief 80mm of journey. The diameter rationale is apparent, however the brief journey primarily boils down to creating it match probably the most quantity of bikes – you solely want 125mm of uncovered seatpost in your bike to suit the brand new BikeYoke Revive 272. Meaning even gravel bikes with almost horizontal or barely sloping toptubes will in all probability nonetheless match the brand new dropper. And like on their “Cape Epic successful Divine SL” dropper, BikeYoke hopes you don’t get so extremely rad in your gravel bike that you’d want 213mm of drop… go away that for his or her greater diameter Revive Max.
The brand new Revive 272 additionally take the cut-to-length adjustability from their short-travel Divine SL dropper put up too. That implies that whereas the 400mm size the Revive 272 is delivered to you is comparable with a protracted 27.2 posts and appropriate for sloping geo XC bikes, you can too lower as much as 100mm off the decrease finish of the shaft for gravel purposes. Slicing it right down to 300mm lengthy general additionally has the good thing about saving an additional 45g for these gravel weight weenies nonetheless studying… after having not been scared off of the outrage of placing a heavy dropper on a dropbar bike.
Tech particulars
BikeYoke claims an actual weight of 385g for the uncut put up – mine was a bit lighter than that because it weighed simply 2g extra with the addition of the non-obligatory 5g mini Revive Fast Reset lever which I wish to have on the put up. There’s a model with titanium bolts that sheds 10g vs. my customary metal bolts. And it can save you extra by chopping it to size, which I ultimately will do after I go into gram-saving mode one wet day.
As regular, the Revive 272 dropper is user-serviceable, and BikeYoke sells reasonably priced service kits which might be fairly straightforward to put in with out sophisticated instruments or hydraulic bleeding strategies.
Using Impressions of the BikeYoke Revive 272
I popped the dropper right into a do-it-all metal cross-to-gravel journey bike a pal constructed for me and drilled for inner routing, to see the way it fared. And I can solely say good issues in regards to the Revive 272. Very like earlier Revives it goes up and down on command similar to it says it’ll, and sure will for a very long time to return. And you’ll even modify the interior air stress if you’d like a extra forceful pop again up.
After having suffered from IFP cavitation on price range droppers that lasted solely a yr or so, I actually respect the worth in paying extra upfront for a Revive dropper that can final for much longer. Admittedly, the Revive shouldn’t be low cost. However I personally have an authentic era 31.6 Revive on a private XC bike since late 2017, and with just a few resets alongside the best way and a <20€ service equipment, it nonetheless works nice. It’s positively the one dropper I’ve nonetheless in service for that lengthy.
Remaining Limitation of Dropbar Droppers
Possibly the only greatest limitation to gravel dropper posts in my view shouldn’t be the added weight – in comparison with my carbon PRO Uncover seatpost this added 171g for the put up alone plus one other 125g in cable & distant – however slightly that distant. BikeYoke doesn’t but supply their very own dropbar dropper distant, as a result of they aren’t but pleased with those they’ve been growing. And I can sympathize. I’ve ridden with just a few totally different dropbar remotes and I’m not glad both.
The tight bends when routed inside a dropbar, and even just below the tape, mixed with making an attempt to wrap your bartape across the distant, all add as much as annoying friction within the system. And let’s not overlook the ache of putting in the put up. To get a dropper into your bike you normally want to slip round 10-15cm of housing by way of your body’s inner routing to get it to stay out of your body to connect the put up. If you’re utilizing an uncut Revive 272, that provides an additional 10cm of housing. Now with a distant beneath your bar tape or subsequent to your stem, that’s unattainable and not using a large cable loop out entrance. (On a MTB bar with the distant subsequent to the grip, you may transfer the distant near your cable port throughout set up, however not likely so with a drop bar setup.)
For now, I believe the perfect answer is hanging a flat bar distant subsequent to your stem, with a reasonably sizable cable loop ultimately. And I’ll anxiously await a BikeYoke Dropbar Triggy distant with a greater routing answer…
BikeYoke Revive 272 – Pricing & availability
The brand new 27.2mm x 80mm journey BikeYoke Revive 272 sells for $370 / 370€ with customary metal {hardware}, or $395€ with titanium bolts. You can even add one among BikeYoke’s flat bar remotes for an additional 40-65€, however they don’t have a mount to suit round a 31.8mm clamping space subsequent to your stem so far as I’m conscious. The brand new Revive 272 is obtainable now direct from BikeYoke.
