Bulletproof Cycles Bulletproof Chain Kit

The Bulletproof Cycles Bulletproof chain kit is one of the strongest, and most durable chain drive conversion kits we have used. The bolt-on carrier design for the rear sprocket is superior to other's cheap spacers. The kit comes complete with 100-percent hardened steel PBI Sprockets, an EK ZVX3 Chain, a Billet aluminum carrier, and ARP hardware. bulletproofcycles.com
