Just got myself a specialized allez sport. it is in lovely condition and has a full tiagra groupset. the right hand shifter is very smooth but the left hand one makes a loud clunking noise when shifting down from the large to small chain ring. I have noticed this before with other shimano shifters that the front mech clunks. the noise seems to vibrate through the frame making it sound louder. i have tried different tensions on the cable but is still doesnt help. the mech isnt catching the chainring, trapping the chain or hitting the frame at all.
any ideas appreciated.
cheers
