hey! i got a brand new 07 Domain 318 180mm version, i am gonna sell it to a buddy for his 07 Cannondale Prophet, and in it's 180mm version it's axle to crown is a bit to high for the bike, i've heard/read and searched all over the sram website, aswell as the manuals on how to reduce it to 160 and not having much luck, can anyone enlighten me on how to reduce the travel on this fork ?
