Take it to the shop or DIY- a Poll

Cables and gears are all taught on the Ctuk courses.

Not that difficult once shown how.

Cheers James, but it's not the know-how that's an issue:

I do everything except for the fiddly stuff that I know I can do, but really would just rather not (Basically, cabling and tuning gears).

Doing that stuff well and quickly is an art (like wheel building, but I enjoy wheel building, so don't mind taking my time). I know I can do it (I've done it a number of times), but I don't enjoy it. I think part of it's the fact that once you cut an outer, it's cut. There's not turning back. There's not much else like that in bicycle maintenance. Also, I tend to forget which limit screw needs to be turned which way. That's annoying.

Ultimately, cycling and cycle maintenance is a hobby and something I enjoy. Not that bothered with the parts that I don't enjoy, so I'll pay someone to have a go.
