If I where you I would stay well clear.
I recently got a pair of wheels built by them and after one short ride I found VERY loose spokes on both wheels, I took them to a well respected LBS to take a look and he was shocked that I had only been on one short ride with them and that any wheel builder would let them go out with spokes with such little tension, His first reaction was to ask if I had built them because of the amature build quality. The spokes where so loose that you could tighten them by hand. He sorted the rear for me but reckoned the front rim was faulty and I should send it back to CRC. So send it back I did, I got an email from them saying it will be a week before they will even look at it.
To say that I am disappointed is an understatement, not to mention the safety implications of having very loose spokes.
On further research into wheel building, I have since discovered (arguably) that a wheel that has been built correctly should stay true most of it’s life, certainly not just for one quick blast round Carron Valley.
