Giant Bikes Bottom Brackets

Kogel Bearings offers two versions of bottom brackets for Giant bikes, a 24mm ceramic bottom bracket for Shimano, Sram GXP and Rotor 24mm spindles, along with a 30mm ceramic bottom bracket for BB30, 386EVO, Rotor and Cannondale SiSL2 crank sets.

Choosing the Right Bottom Bracket

Even though the frame dimensions are slightly different between Giant road and mountain bikes, our bottom brackets are the same. Only your choice for road or cross seals separates the two.

PressFit Not PressFit30

Giant Bicycles has a long collaboration with Shimano. It is no surprise that Giant's frames follow the BB86 and BB92 standard developed by Shimano. The official name is PressFit, but we tend to avoid it since it is too confusing with PressFit30.

WHY Upgrade/Replace Your Bottom Bracket

Even new bikes with new high-end drivetrains can, and usually do, ship with bottom brackets using steel bearings.

Even if perfectly maintained, those steel bearings just won't roll as smoothly or efficiently as our ceramic steel bearings.

Kogel Ceramic Bearings are:

  • More symmetrical (i.e. round) and built to stricter tolerances than steel bearings
  • More efficient for power transfer than standard bearings
  • And, won't deform, flat-spot, crack or get pitted

Beyond the basics of keeping your bottom bracket clean and maintained, perhaps the most important step is ensure your bike's best performance is using a bottom bracket manufactured with high-quality ceramic bearings.
