Defintely parts to make the bike lighter, also trouble finding Kinetix Pro wheels/rims. I myself looking for Kinetix Pro front 14 hole wheel and rear 28 hole rim, both in Red. Also SRAM Automatix 2 speed 28 hole hub. The only places I able to find them is either in Germany or UK, either shipping cost to high or don't ship to US. That will be great you get this started.
