Just wondering which on line store come up the cheapest for parts. I have used Merlins quite allot but what others are out there?

Merlin's fork prices are pretty hard to beat. I tend to search between CRC, Wiggle, Merlin and UK Bike Store.

Any of merlin, chain reaction or occasionally wiggle. All good service, but prices vary so you need o check for specific bits.

i'm usually lazy and just use crc, but wiggle, chain reaction, rutland, and uk bikestore are all good. if i'm in a hurry i usually used google to get a pricematch, print it and go to evans gatwick and pick the stuff up there and then.

I have quite a few things cheap on Amazon

Ribble have been very good to me recently!
