Maybe some new cables too.

I need to replace the inners and outers on my old charger/turbo/off-season bike as its getting cantankerous. I suspect the rear mech is out of alignment too as it won't index properly and the gear change via the rear mech is getting on my nerves. The headset bearings are on the way out as well and I did not replace them that long ago, but with some cheap ones; so buy cheap, buy twice as they say...
