Finally got around to checking the bottom bracket on the Alien and there seems to be too much play in the bearings hence the clicking.

Its a sealed unit with the following markings:

FP-B902/2T
L126

BCI 37"X24T

L <= 68 => R

Am I right in thinking this is a drop in replacement?


Shimano UN54 68mm Square Taper Bottom Bracket

Shaft length is 125mm

Any help appreciated, thanks!

Thanks to all who replied, I was inundated! :D

The one I linked to above fitted fine, for ref the shaft length is 127 mm

One small problem is the shaft diameter is greater than the original item so the pedelec sensor needs modifying to fit the shaft plus the sensor spacer won't fit so some washers are also needed to pack it out....
