Any question answered...

My LBS has informed me that the gear and brake cables on my recently purchased (second hand) road bike are a bit squiffy and could do with replacement. I don't want to spend too much seeing as I've just splurged on a new bike, but can anyone recommend a bundle I can get online that will do the job? I need all the ferules etc too as those are a bit fucked too. Preferably not too ugly as the bike is quite nice...

squiffy how? Off the top of my bonce

Rock and roll cable magic lube is reported to rejuvenate and work wonders on old/new cable alike. If you want to replace then for gear cable outers goodridge do compressionless housing meaning the cable sees a constant diameter through bends. Thats £5 per metre i think. To my knowledge the cables themselves are much of a muchness, but pre-stretched wouldn't do any harm.

Gore are touted to be the best apparently. £30 - £40 for a set i think, but I'm not sure if they're only MTBs specific

Cheapest option for complete replacement would be a kit by clarks for ~£15-20 probably.

Most importantly, be sure to install the cable outers properly with a decent pair of wire cutters. I used a dremel. You need a clean edge. As explained by Sheldon http://sheldonbrown.com/cables.html
