BB86 for Shimano
Shimano cranks fit into
BB86 frames when you have this CeramicSpeed Bottom Bracket installed. The
kit consists of two cups that are pressed into either side of the central
opening.
The cups come with
CeramicSpeed Bearings installed. There are two versions. The first is our
low drag, long life Standard Bearing, with hardened-steel races and our
super round CeramicSpeed Balls. The second version is our coated bearing,
which uses those same CeramicSpeed Balls installed on coated,
hardened-steel races for longer life and less bearing drag.
Technical Data
This CeramicSpeed BB86
Bottom Bracket works with cranks that have 24mm thru-axle spindles, including
both Shimano and FSA.
CeramicSpeed standard
Bearings typically have frictional drag of 0.3-0.4 watts per set. That
represents an average 75% drag reduction compared to standard bottom
brackets. The hardened-steel races feature the CeramicSpeed Balls that are
100% smoother and 15% harder than the ceramic competition. The CeramicSpeed
Bearings last at least three times longer than other bearings.
Coated Bearings drop
friction further and increase lifespan. The coated races see a 50% drag
reduction and an improvement in bearing life of 60%.
Changing the grease can
tune performance. All Round Grease comes installed, but can be changed for
lower drag TT and Track Grease, or higher durability LongLife Grease, which
adds a bit of drag but stays in when riding through messy conditions.
