OK, so I made my first part! Well, kind of - it's a wooden mock-up of the pair of adapters I'll make for my $90 wheel/tyres to fit the 25mm rear axle I'll use. The mock-up shows that it works but that I'll have to countersink the bolts coming through from the back of the adapter and into the wheel hub. I chose this side (92PCD) of the wheel rather than the other side (100PCD) to attach to the adapter because the wheel hub is clearly stronger on this side. To be clear, I'll be changing the two existing 15x37x11 bearings in each rear wheel, and substituting four 25x37x7 bearings in each wheel (two each side), so the adapter does not carry any weight load, only the driving and braking load. Have fun! Simon
