Product Description

Among the new bottom bracket standards in the bike industry is BB86. It offers frame designers a little more room for new designs in seat/down tubes and chainstays. Where a typical road bike has a 68 or 70mm bottom bracket shell width, a BB86 equipped bike has a shell that measures 86.5mm wide. A BB86 shell lacks internal threads and has a 41mm inside diameter.This Shimano BB86 Bottom Bracket Assembly is made to press right into your bike. It will mate your Shimano HollowTech crankset to any frame equipped with a BB86 bottom bracket shell. Frames that use BB86 bottom brackets include bikes from Scott, Giant, and plenty of others. This bottom bracket comes with two steel cartridge bearings pressed into composite cups. The cups increase the outside diameter of the assembly to 41mm to match the i.d. of the frame's bottom bracket shell. There is a 1.75mm thick outer lip that provides a positive stop for the cups when you press them into place. Shimano includes their standard plastic o-ringed inner sleeve to protect against water damage should it find a way inside your frame. It uses black plastic dust shields that snap into the inner race of each bearing.

Do I the use spacers that come with the XT crank to resolve this, although I don't use the XT bottom bracket? Thanks!Read More »

Single Speed BB86 Eccentric Available?

Hey there, if my geared frame has a BB86, is there an eccentric available to make it single speed? I believe the difference in 86 vs 92 is that the 86 uses a road crank, not a mountain crank. Can someone offer suggestions, I only found these two EBB's for oversized BB shells: - [B]Problem Solv ... Read More »

SS crankset for press-fit BB86

The crankset I wanted may not work for the frame I'm building up. Can anyone suggest a good (light, strong, bad ass, etc) single speed crankset for a BB86, press fit only. I'm open to suggestions. My original plan was to use an e13 SS crank, but it looks like this might not work.Read More »
