• Well the axle conversation didn't go as planned. I purchased a 10mm x 170mm rear solid rear from SJS but it's not. The 10mm track but doesn't go on. The current hollow axle is 10mm so I don't know what the problem is. There is a 10mm + 1mm axle available to buy so maybe that's what I need? The front should work fine so yay for that.

    And has anyone done a hollow axle to solid axle swap on a SP Dynamo Hub?
