Swop out the old bearings and fit the new stronger new style bearing.
The new bearings are nearly 30% stronger than the standard bearings. We get rid of that awful nylon shim and fit the bearing straight onto the Hollowtech II axle. It also comes with a better seal, if you want to use it as the bearings are fitted with rubber shields. It does help to keep the muck out.
As an opening offer, for a limited time. If you send me your bearing cups we will change the bearings for you at no extra cost.
