After 1300 miles the Tiagra (4600) front mech has got 'notchy'. It's not the cable. I detached the cable and worked the mech by hand but it really needs a bit of 'encouragement' to go the last few mm inbound to the smaller cog. When riding it needs a kick or a push to change to smaller ring. I think some recent seriously wet rides have taken its toll.
Obviously I am a tad loathed to replace like with like. I have Tiagra 4600 shifters. Can I replace with an Ultegra front mech? Does it matter if it is 6600 or 6700 front mech?
Really confused. TIA

I may be wrong but I thought things changed between x600 and x700. Maybe that was just brake pull.
Aha finally found the 2012 [url= http://bicycles.stackexchange.com/questions/7629/will-it-cause-problems-if-i-use-components-from-different-series ]Compatibility Chart[/url]. Why isn't that readily available on the Shimano website?!
Looks like I'm alright with x600 / x700. Tho you may be right about the brake pull.
