I bought 2 wheels on ebay not thinking the bearing size might change. They were 96's. The front has a 17mm bearing and the rear has 20mm bearings. Rather than taking the wheels apart and making the 20 and 22mm bearings fit I thought I would sleeve some axles to fit the bike (01-426). My ? is: What years use the 17MM axle front and 20mm axle rear?
