Bought a pair of these for my Charge Plug single speed. The wheels are much better than I expected to be honest. the hu bolts are 0.5mm thicker than the old wheels making them a tight fit on the rear drop outs but the axle bolts are better quality than on the old / original wheels - they roll better than the old wheels too, so I would say the hub bearings are likely better quality, the acceleration is a bit better, as in easier, but the biggest surprise was the improvement n ride quality (same tyres / inner tubes) which is a big plus. Fantastic value for money.
