We covered the launch details of the new OneUp Components Switch chainring system as soon as it came out. But we’ve also had our hands on a set for a couple days, and it’s pretty slick. Here we’ll show the install notes and actual weights of a few variants, and next week provide first ride impressions.
I received spiders for SRAM, Race Face and Hope, along with three different size and shape chainrings. The short of it is this: It installs incredibly easy, and chainring swaps are exactly as fast and easy as they claim…
It’s almost this fast.
Even without practice, it was under 90 seconds to pull a chainring off and put it back on…and that’s because I wasn’t sure how many rotations of the allen wrench to make (about 2.5 full rotations works). My second attempt was quicker. It’s easy to see using a smaller gear on the way up the mountain then switching to something a little larger for the descents if you’re racing enduro and really want to pull out all the stops. And as an earlier commenter mentioned, this would indeed be perfect for cyclocross if they make a bigger version.
The chainring and carrier are machined to nest around the bolts, which are threaded in from the back of the carrier.
The bolts are hollow, so you can loosen them from the outside, but it means the rotation is reversed – righty loosey, lefty tighty. The chainrings are clearly marked with their tooth counts.
To install a chainring, simply loosen the bolt, position the ring so you can rotate it and slide it onto the carrier, then tighten the bolts. Reverse the process to remove it. Literally, a minute’s worth of work once you’ve done it a couple times.
A view from the backside.
Carriers come in at 32g (Race Face Cinch, Boost), 35g (Hope, non-Boost) and 31g (SRAM, Boost). Yes, that’s with five bolts being weighed and, yes, you only need four, so subtract one gram for catching that. They come with four back bolts and one green one. Go stealth or fly the OneUp colors, your call.
My test chainrings weighed in at 56g (34t round), 48g (32t oval) and eeg (28t oval). Stay tuned for the ride report late next week.
