BB86 allows for bearings to go almost directly into the frame. It's an 86mm wide, 41mm inner diameter shell. With the BB86 Campy UT Bearing Kit, you're pressing the bearings onto the Campagnolo Ultra-Torque spindle, then fitting the cranks into the bottom bracket.
The CeramicSpeed Bearings are the essence of the kit. There are two choices. The first choice is our low drag, long life standard bearing, with hardened-steel races and our super round CeramicSpeed Balls. Second is our Coated Bearing, which uses those same balls installed on coated, hardened-steel races for longer life and less bearing drag.
IN THE BOX
The Ultra-Torque spindle starts as two pieces and is connected via a Hirth joint. The bearings are installed on the spindle and resting against the arms. A removal/installation tool is necessary; we sell one here, but any appropriate tool will work. You will also need Campy's BB86 UT-compatible cups to go in the frame.
Our CeramicSpeed Balls are 400% smoother, 128% harder, and 58% lighter than steel balls. By installing them in hardened-steel races, CeramicSpeed standard bearings typically have frictional drag of 0.3-0.4 watts per set with standard grease. Approximately a 75% drag reduction compared to standard bb's. The CeramicSpeed Bearings also last at least three times longer than other bearings.
The CeramicSpeed Coated Bearings further boost your performance. The coated races find a 50% drag reduction and an improvement in bearing life of 60%.
Changing grease adjusts performance to your needs. All Round Grease comes installed, but can be swapped for lower drag TT and Track Grease, or higher durability LongLife Grease, which stays in better riding in messy conditions.
We recommend that you follow our instructions on how to maintain your CeramicSpeed Bottom Brackets to achieve the lowest friction and the best longevity
