I find CRC pretty dog shit to be honest. They always screw me around, i have ordered from them 7 or 8 times and only once has my stuuf come next day and that's because i ordered it at 10 in't morning, and they were spokes.
Usually they come within 2 - 5 working days, it took CRC a whole week to deliver my first set of maggies, even when they were in stock.
Wiggle are also queer :)
Edit: some of that may be phrased weird, cos i'm mainly slagging off CRC :-
I stick to TartyBikes if i want something fast, or cheap.
