'sloppy' shifting on 105 compact
Because I already had a 105 triple,when i changed to compact on my Kinesis Ti the LBS said I could keep all the levers and mechs and just change the crankset.Once the mechs stops were set they were fine..The front lever says triple on it the rear one just 105.The rear mech is long cage.Recently though I'm having to 'double' click a lot of the rear changes to get them to move cleanly and it's getting annoying and just feels sloppy.So I want to tighten everything up.
Was thinking ultegra RD6700 rear mech as it will take the 12-30 I use.I assume this will work fine with the 105 front lever? Or do I need an ultegra shifter.Is the pull etc any different?
The front mech is a triple one but front shifting is ok but does take a ' long' sweep of the lever to do it.Should I swap to double front mech at the same time?Again would this work with the triple front levers?
Any other tips would be much appreciated.thanks

I suspect your rear mech cable has crudded up a bit and is now sticking in the outer - probably the bit down by the back wheel ... take it off and uncover the normally hidden cable and I bet you it'll be gunky ...
Either clean it or replace (inner and outer) - it's probably the same for the front too - although the long sweep is the lever itself rather than sticky cables ...
Easy way to inspect it without undoing anything:-
have the bike in lowest gear (largest rear sprocket) then without turning the pedals, just upshift all the way till you run out of clicks, while pulling the cable to maintain a bit of tension. That should leave you with enough slack to unseat the small loop of outer cable at the rear mech from it's stop on the chainstay. That in turn will allow you to push the cable back through the shifter to examine the nipple and the first 2-3 cm of cable.
