Current Projects chat and miscellany

Not sure if its the wheel size (27" vs. 700c) but on every group ride on downhills, I catch people/ take them very easily, despite having a poor aero position, a non 'aero' bike. Obviously on the ups, my lard arse doesn't quite operate in the same way. but still, rolling resistance can be massively different between various hubs/wheels/tyre combos.

Not being awful, but I seriously doubt that is down to your hub bearings. The 27" wheels will probably have more of an effect.
