Boardman Team Carbon - Chain Rubbing on Front Mech
After adjusting all the gears the chain still rubs at certain points, quite simply we don't believe the Tiagra from mech is wide enough and no matter what adjustment is made certain gears will cause the rubbing.
Not sure if this has been discussed before but would another make of front mech solve the issue (or take a crowbar to existing one to widen it )
Consider getting a different rear cassette with an 11-28 at the back anyway to help an unfit (2 new hips) heavy smoking wimp get up the hills easier so thought I'd get both done at once.
If this is common, can someone suggest a front mech that would solve this
