I spent some time where I was addicted to all of the back country sites... chainlove, bonktown, steep and cheap, etc. I have a lot of gear that came from back country. I saw those brakes yesterday and if I had the cash layin around, I would have bought them.
just fyi... i e-mailed competitive cyclist (owns chainlove) and I said hey I have money to spend on bike bling. I saw a $20 off $150 coupon before the holidays I wasn't able to take advantage of. When is the next coupon coming or I might spend money somewhere else. THEY e-mailed me a loyalty code. $20 off $150 or $50 off $300. Spent $250 after coupon. SWEET. Sweet deal for X01 cranks & BB. Give it a go if you might get lucky!
