I've got myself in a right pickle with my gearing. Last time I rode some of the cos were being missed or making lot of noise, so after doing a it of research and reading the installation manual (Shimano 105) I tinkered about with the barrel adjuster and limiting screws, noting seemed to get it quite right, often made it worse.
I got to the point where all the gears were engaging if a bit noisy and thought right, that's it I'll ride it. Then 10 miles in the highest gear starts trying to shift into the frame.
The bike is a couple of months and 600 miles old and kept in good order so I doubt it's a problem with kinked cables or worn teeth etc.
Every time I adjust something, one problem is solved but another is created and I'm starting to tear my hair out.
Any advice, suggestions, or links gratefully received. I really think this is something that shouldn't require a trip to the local bike shop.
Is it possible to perhaps 'start again', going back to the way it would have been supplied and start as though I was fitting it new, following the manual word for word? Should I remove the cable?
Thanks to anyone who can help as I'm really going round in circles now.
