Pompino and Claude Butler track but not for long, they are barely used. They mount fine on a steel (springy!) 120mm frame, but I wouldn't use them on an aluminium 120mm.
Phil Woods hubs (36H BMX, so 100mm/110mm front/rear), NOS Araya 700 rims, White Industries 18T Trials freewheel, Kenda Small Block 8 700 x 32 tyres. Wheels had around 30 miles use, freewheel around 5.
