Well it states that "the Catalyst is very similar to the Enduro... it has identical geometry, except the chainstays are ½" (1.27cm) longer", the error being that both the Catalyst brochure and the Enduro brochure have the chainstay length as being 408mm, not sure which one is correct. My guess is that the Catalyst chainstay length should be 421mm. What do you think?
