Thanks for your replies . Well I have totally lost the plot on this one . I have never been happy with the sti front gear change on the triple .But buying a new inner ring ,chain guard , front mech ,chain and cassette ( last two because the old ones are a bit cattle trucked ) for less of a gear range and having to double change when drooping in to the granny ring didn't make much sense to me . So I have pulled off the triple levers, fitted old non aero brake levers & simplex friction gear levers . Put the old 48/38/28 triple crank back on . Bought & fitted a new 8 speed cassette & chain and its bloody brilliant . So easy to set up /changes gear like a dream . And should be cheaper and longer lasting than running 10 speed chains and cassettes ( judging by the old 7 speed bike I own ). Happy days colin
