Switch v2 Chainring

One of the most efficient and affordable ways to handle the increasing number of chainring and crank standards, the OneUp Components Switch Chainring keeps your chain in place on the roughest terrain and costs a fraction of the price of a complete direct mount chainring. Due to a unique ring-to-spider interface, the ring detaches and slips right over the crank arm with just a single tool (4mm Allen key). This means there's no reason to take off a crank, or spider, or bring along multiple tools just to make a simple gear change.
