Velo Orange Eccentric Bottom Bracket Bearing

These bearings are designed specifically for eccentric bottom bracket systems that utilize a 24mm spindle. While they are a standard size for many setups, you should verify your current bottom bracket shell and spindle diameter before purchasing to ensure compatibility.

No, these bearings are non-side specific. They are sold as a pair, and both bearings are identical, which simplifies the installation process.

Installation typically requires a bearing press tool to ensure they are seated evenly and without damage. We recommend using a proper press rather than a hammer or punch to avoid compromising the bearing seals or the eccentric housing.

Common signs include a gritty feeling when rotating the crank, audible clicking or creaking noises while pedaling, or noticeable play (wobble) in the crank arms. If you feel resistance or roughness when spinning the cranks by hand with the chain removed, it is likely time for a swap.

Yes, these are high-quality sealed cartridge bearings designed to keep out dirt and moisture. They are built to handle the rigors of regular riding, though regular maintenance and cleaning of your bottom bracket area will always extend their lifespan.
