Comments about Shimano Ultegra SM-BBR60 Bottom Bracket:
I just installed this BBR60 (Ultegra 6800 BB) on my 2010 TREK 1.2 and paired it with the Ultegra 6700 Crank set and am very pleased. I am only training inside due to weather in the NE but I enjoy the smoothness, the fit, the look it's a nice upgrade from my stock BB. As usual Nashbar beats all in price
Was this a gift?:
Bottom Line Yes, I would recommend this to a friend
