good basics ! but they are not really covering my problem ie how to calculate my spindle length.
in most case the crankset compatibility will just say “compatible with 68/73 bottom brackets” but i would like to know how to get rid of the excess spacers on my next crankset purchase
i dont mind having spacers on the bottom bracket but i dont like having spacers on the spindle
i finally got rid of the creaking noise on my raceface turbine cranks. they come with a nylon “pre loader” ring that allow you to adjust the gap usually filled by spacers. i replaced it with a cane creek aluminium one (33£ brand new ordered from the cool local bike shop)
here is pics and a breakdown of the setup:
turbine raceface 30mm spindle ( most cranks spindle are 24mm) (90£ on ebay second hand)
T47 chris king bottom bracket External or X (there is a internal one as well) (100€ on troc velo second hand)
Stolen garage recomanded me the T47 BB Shell and after researching on it it sound like a good idea if you want bombproof combo : bigger spindle size is more stiffer and not much weight difference. the T47 BB has bigger bearing sizes in. hopefully it will outlast me.
