Replace that old worn out or cracked swingarm with this new one! New Old Stock: Trek Fuel Swingarm. Made in the USA! This will fit model years from 2001-2006. Fits models like Fuel 80, 90, 100. Note, this is an all-aluminum bonded swingarm, whereas the Fuel 100 had carbon stays. This will fit that model, but it is not carbon. This will fit all sizes of Trek Fuel mainframe sizes - from 15.5" to 21.5" or SM to XL. This actual swingarm is painted the same Red as the 2001 Trek Fuel 80. This does not come with derailleur hanger or bolt. You will need to take that from your existing swingarm or obtain one through a Trek dealer. The brakes have cantilever/linear pull bosses on them, but this also can be converted to rear disc brakes if you have the compatible adapter that mounts to the rear left dropout. I do not have that adapter. Swingarm only with new bushings installed. Does not come with pivot hardware. Full bicycle picture only for reference. Buyer is responsible for proper installation. Pivot hardware must be torqued to proper torque settings. If in doubt, have a local bike shop install it. Shipping to the USA only. Sorry, no International Shipping.
