OneUp Components Switches Up Chainring Design

by
March 8, 2017

Canadian company OneUp Components has been producing some innovative and highly popular drivetrain items over the past couple of years, including modified derailleur cages, direct mount chainrings, and a huge 10-50t cassette hop-up kit.

But as a manufacturer of chainrings, OneUp Components is well aware of the many different standards currently found on the market and the many headaches that this can cause. For a start there’s round and oval chainrings, and then there’s numerous direct-mount cranksets including Cannondale, RaceFace, SRAM and Hope. On top of that, you’ve got Boost offsets and even Super-Boost offsets.

That’s a whole lot of SKU’s for a company like OneUp Components.

Chainring standards. A pain in the arse that OneUp Components is well aware of.

With its sights set on future-proofing (as much as one can in the bike industry…), OneUp Components has launched the Switch chainring system. Before going any further though, OneUp Components is keen to point out that Switch isn’t a new standard. Instead, it’s simply a way of creating a modular spider/chainring system that offers greater flexibility when it comes time to replace or change out a ring.

Wolftooth Components is using a similar modular system for its chainrings called CAMO, and the overall premise is the same. By turning a direct-mount chainring into two components (spider and a chainring), more combos are possible with less SKU’s and replacement chainrings are cheaper. However, the OneUp Components design is a little different. This design possesses a very clever mounting feature that offers much quicker removal and installation…

The central modular spider on the Switch design.

The inner part of the Switch system is the modular spider. This spider comes in a variety of different direct mount styles to suit current RaceFace, Hope, SRAM and Cannondale cranks. It’s also available in standard and Boost offsets.

The green bolt at the top right of the spider is the mounting bolt. All you need to remove the chainring is a 4mm hex key to loosen this bolt (and the three black ones). Undo them a couple of turns, and then the chainring can be rotated and pulled off, all without need to remove the cranks from the bike. Many of the direct-mount chainrings on the market require a more involved process to install and remove them, so OneUp Components is selling this feature to racers and those travelling with their bike, who might want the ability to quickly swap chainrings in the carpark before a ride or race.

Narrow-wide chainrings are available in standard and oval shapes.

The outer chainring itself kinda looks like a 4-bolt chainring with the tabs partially removed. The tabs mate up to corresponding pockets on the central spider. From an ease of use perspective, it certainly sounds appealing, but we’d be keen to see how the design fares in the real world.

OneUp Components didn’t give us any weights in the press release, but needless to say the Switch design is likely to be heavier than an equivalent single direct-mount chainring.

The Switch design claims quick installation and removal for ninja chainring-swappers.

The design means you can remove and swap chainrings without having to take the cranks off the bike. As an example, the existing SRAM direct-mount chainrings require the cranks to come off the bike, before undoing three small screws in the back of the chainring that keep it mounted to the crank arm. In the case of the Switch design, all you’d need is a 4mm hex key.

Yes, apparently there are that many. Get closer and squint, and you should be able to make out a man in the distance, pointing and laughing at how many chainring standards there are.

Confused as to how it all goes together? Thankfully OneUp Components has made a neat little video of all the happenings with the new Switch design, which you can watch below.

Switch chainrings will sell for $63 USD, and replacement rings on their own will be $40 USD. For more information on the rings and other products, head to OneUpComponents.com.
