OneUp Components Switch Carrier NOTE: OneUp Components Switch Carriers are only compatible with OneUp Components Switch Round & Oval chainrings. SwitchCarriers and Chainrings are sold separately, but can be purchased as a complete systemon each product's page by clicking on the appropriate icon above the Add To Cartbutton. Be sure to choose your chainring 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, offered in 5 popular mounting standards and 3 offsets, as well as your choice of Oval or Round chainrings (sold seperatly) 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 theses 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. Features One tool ring swaps are possible with just a 4mm ring allen key. 5 Ring Sizes in 28t to 36t counts for a dialed gear ratio. 2 ring profiles available Round or Oval.
