I have a 2007 Norco Shore w/a 888 Marz. The bike was obviously designed around a 7" Marz. 66 with a high B.B. for tech riding. The problem I have is I want to race and with the 888 my B.B. is really high. I think a 24" might help lower the B.B. and slacken the 66 degree H.A. After talking it over with my mechanic I'm still not satisfied that the rolling resistance problem inherent with the 24" wont be offset by the lower center of gravity and slack H.A. Also I have a friend with an old Bighit that runs the 24" and he seems to do really well on it. What should I do? And is it worth the effort to put money into a heavy freeride bike. Is it just going to be a heavy freeride bike thats slacker and lower if I do drop the money?
