CeramicSpeed Colnago Threadfit T45 Bottom Bracket For 82.5mm Frames - Campagnolo Ultra Torque From  £219.95

Some people's comments I've read on certain bike forums fume at the cost of this item, and the fact that it's proprietary to the C59, C60 (what I have) and the C64. While I'm not privy to the reasons why Colnago chose CeramicSpeed to partner with, but the greatest bike frame manufacturer in the world obviously had their reasons. Nuff said.
