Hi guys, Appologies if this has been done before... but how do the SRAM double shift gear levers work??? Dose the same lever shift up and down??? I have been offered a boardmans carbon road bike as a insurance replacement from halfords.... I really like the look of the bike, and read good things about them but halfords??!?!?! I went into my local one today, the KID that served me couldn't explain how the shifters worked??? and didn't know how to put pedals on it for me to try it for size... The bike looks lovely though, i just couldn't get my head around the shifters.... Any one here have this bike and could shed some light or advise when dealing with halfords??? Thanks!
