OneUp Components have come a long ways since those early days of cassette adapters. The availability of cheaper wide range cassettes has likely decreased demand for such adapters, but fortunately for OneUp – their product range has rapidly expanded since then. And with launches like this one with three new components, the brand shows no signs of slowing down any time soon.
12 Speed Shimano Switch Chainrings
Need a different tooth profile? Wore out your chainring teeth? Then Switch it. But just the outer ring. And in less than a minute. Without removing your cranks. That’s the idea behind the OneUp Switch direct mount system, which has been around for some time now.
The big news now is the addition of 12 speed Shimano compatible chainrings. The interesting thing here is that OneUp’s chainring tooth profile already claimed to be both SRAM Eagle and Shimano Hyperglide+ 12 speed compatible (as well as 8, 9, 10, and 11 speed compatible). The difference here is the direct mount spline interface for the crank is designed to fit the new Shimano direct mount XTR M9100, XT M8100, and SLX M7100 cranksets.
Available and in round or 12% oval shapes, rings will be offered in 28, 30, 32, and 34t. The carrier only will start at $23, and full ring set ups add $40-$44 on top of that.
Axle-R
Looking for a match to your Axle-F? Now OneUp is offering the Axle-R. The R is for, you guessed it, rear.
Like most replacement axles, OneUp claims the Axle-R is lighter, and better looking than stock. They also claim it’s stronger since they opted for a solid 7075-T6 aluminum construction rather than hollow. The axles include different size spacers to allow the same axle to work for four different widths. Black is stock, but colored shims are offered for $10. The 12mm axles are available for all major axle standards except Syntace X-12, and start at $39 each.
34.9 Dropper Post V2
While the Dropper Post V2 isn’t new, the addition of a 34.9mm size is. Proponents of the size say that there’s more room inside to fit the internals of the post so they end up being more robust, and you end up with a more durable post. The problem is that the size isn’t widely used so many manufacturers simply don’t offer a 34.9. But now you can get the OneUp V2 in a 34.9 in any of their lengths – 120, 150, 180, and 210mm lengths (which are also adjustable up to 20mm). Pricing starts at $199.
For those who want to get the absolute most out of their dropper (who doesn’t?), OneUp offers their online dropper post length selector tool here. You’ll need to take two measurements on your bike, then punch them and and the tool will tell you what length dropper post from OneUp that you can use, as well as what lengths from some of the most popular competition. Spoiler alert: it looks like OneUp will almost always offer more travel for any given set up.
