i have a 1980 Centurion Omega, yes I am a newbie. I want to do my first Tri in April '11. my bike is pretty much all original as far as I know.
I want to get aero bars and bar end shifters but i don't see 12 speed bar end shifters anywhere.
Should I convert to a different number of speeds? 12 speed doesnt seem to be around any more.
Many more questions but this is a start. Thank you for all of your help.
