This is a 2010 Chumba F5 ridden by a sponsored Chumba rider. The bike runs perfect and is one of the smoothest bikes you will ever ride. It has scored many top 10 finishes at national races in 2010. The bike was completely rebuilt after every race by a professional mechanic. All parts are 2010 or newer. The fox suspension was also rebuilt multiple times through out the year by fox. The bike has absolutely no problems what so ever and is ready to ride. If you have any questions give me a call or email me at or respond to this ad. NO TRADES Price is OBO so open to offers.
