Wheels Manufacturing PressFit 30 Bottom Bracket
Introducing three all-new PressFit 30 bottom brackets. 100% made in the USA. We understand that the heart of your bottom bracket is the bearings themselves. That's why we've decided to produce our PF30 bottom brackets exclusively with Enduro Bearings. Wheels Manufacturing is the only company currently offering PF30 bottom brackets with a choice of bearings in standard sealed bearing, angular contact bearing or ceramic bearings. Radial deep groove bearings that have 5/32" Grade 20 balls, the largest in the industry, resulting in a 12% increase in static load compared to standard 6806 bearings. Dirt is kept out by no less than two double lip seal systems from the outside elements. The bearing seals are dual lip, groove type seals rather than standard 2RS types that other manufacturers use; one lip to keep the dirt out and the other to keep the 90% grease fill inside. Bearings are filled both sides with Mobil HP 222 synthetic grease for the best protection and long lasting set up. Another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration.
