A friend's rear hub stopped spinning on a recent ride, described as "crunchy". The 17mm bearing extractor allowed easy removal of the drive side hub bearing and a punch was used to remove the remainder of the non-drive side bearing. A 17mm wrench and a soft hammer allowed the removal of the inner race from the axle. A magnet retrieved the loose bearings from inside the hub shell before a thorough clean. It appears that used a smaller 17 x 26 x 5 mm bearing, pressed into a reducer, on the earlier editions of their Gen1 hubs. They later replaced this complicated arrangement with larger 17 x 30 x 7 mm bearings which are more robust. The 30 mm threaded press made short work of the new bearing install. It is a real joy to use simple but well made tools. The whole job was made easier with excellent tools from and l***s applied from l**e toobs. grease in the hub and freehub grease for the ratchets. The hub is again as good as new and ready for another few years of rolling good times.
