Note: Oneup Components Switch Oval Chainrings are only compatible with OneUp Components Switch carriers. You will need a carrier that fits your crankset to use this chainring. Switch Carriers and Chainrings are sold separately, but can be purchased as a complete system on each product's page by clicking on the appropriate icon above the Add To Cart button. Be sure to choose your proper carrier before checking out. Use the item description to choose the correct fit as the images are for reference only.
The OneUp Components Switch system is a two-piece direct mount spider and chainring system. It consists of a direct mount spider (sold seperately), offered in 5 popular mounting standards and 3 offsets, as well as your choice of Oval or Round chainrings ranging from a 28 to 36 tooth count. It's also one of the most efficient and cost effective ways to deal with the increasing number of chainring and crank standards. The rings are removed and replaced easily due to a unique ring to spider interface. With just one tool, a 4mm allen key, the ring is dethatched and slips right over the crank arm. No need to remove a crank, spider or have multiple tools on hand to make a simple gear change. In matter of minutes, dial in your gear ratio, even between stages of your local enduro series on race day.
With these quick-change rings and cheaper replacement costs, Switch has some very enticing benefits over the standard one-piece direct mount chainring set up. Get into a complete Switch chainring system at the same price as an existing direct mount chainring, but now the ring and carrier can be replaced individually and at a fraction of the cost.

I love the RaceFace Cinch system - but changing chainrings for one or two days of riding was always a hassle. The OneUp system takes that all alway - quick easy changes. Great chainrings. Even stopped using a chain guide since these suckers hold the chain on all the time.
Well made, machined perfectly so installs on switch hub quickly. Primary reason for purchase was to allow foe relatively easy gearing changes on my single speed. And it completely meets my needs. The oval ring was noticeable at first, but felt natural after a couple miles. I would have to alternate between round and oval to determine if there is a difference in power delivery.
