Chain Device -- MRP WC1 or WC2 for BigHit Expert ???
I have just got my first proper DH bike and am upgrading it to get ready for the racing season next year.
My bike is a Specialized BigHit Expert '04 and want to put a 42 Chainring on (standard 32 is far too small) and a MRP World Cup Chain Device. Does anyone know whether the WC1 or WC2 will work on the big hit and what the difference is between them? I keep reading about an elevated chainstay but don't know what it is? Also, any tips on the chainring would be good.
