Thanks to help from this forum, I've manage to convert my wife's bike using a Cyclotricity front hub kit and I'm now trying to do the same with my old hybrid. However, I have one outstanding 'gotcha' to resolve:- the PAS rotor (see piccy) as supplied doesn't fit the bottom bracket spindle -- even though the exposed section of the spindle is within OEM specs (see piccy). The exposed portion of the BB spindle is 2.1mm (see piccy) but the PAS rotor is 4mm thick!
The 'hole' in the centre of the PAS rotor is ~32mm dia and the 'inner spigot' of the crank on that side is ~30mm dia x ~3mm wide. So my gut feeling is to remove all but 1mm of each 'finger' in the PAS rotor centre hole and then glue the rotor to the crank using epoxy. However, I suspect that someone might have modified one of these rotors and might have a better idea. Hence words of wisdom from the forum will be gratefully received.
Thanks for looking. Geoff
