I recently bought a frame and all the bits mail order as well. I asked the guy if he had any brakes on special offer and he said he had some Juicy 7's.
They were slightly lower than CRC prices so I took them. When they arrived it was clear they were second hand. Then he changed the rims I had ordered to tubeless rims without telling me. Then the fork turned out to be a standard QR rather than a QR 15 I had requested. (The order was posted in three separate lots)
Now, I've easily bought £10k plus worth of stuff from this guy over the years and I'm pretty annoyed. Should I send it back or bite the bullet? Am I over reacting? Would really like to have a bike over Xmas though!
