dude...:
i guess it depends on the tolerances between different manufacturers/factories
RighteousBMX:
Profile spindles will work with Taiwanese 48 spline cranks but it'll be a loose fit. Taiwanese 48 spline spindles will not work with Profile cranks. He was just highlighting how the subtle differences in spindles just complicates things even further for shops, let alone all the different sprocket drive options (19mm, 22mm, 24mm).
G:
PLEASE NOTE: THIS IS ALL IN RESPECT OF 22mm. IF YOU HAVE 3/4"/19mm THEN YOU ARE FINE.

YES.
--- Quote from: Admiral Ackbar on October 28, 2014, 09:24:54 PM ---its coz profile uses imperial measurements so their 22mm is actually whichever imperial fraction is closest to 22mm, which is 7/8" or 22.225
basically, profile is retarded

NO. Profile is not using 7/8" (22.225mm) like they did on the OLD SS cranks. They are using 22mm but it is fractionally different to the 22mm that Taiwan uses. Different tooth angles and major and minor diameters.

NO.
It isnt down to tolerance, it's actually different at a fundamental level.

NO.
The Profile spindle MIGHT hammer into a Taiwan crank arm, but I very much doubt it, and it sure as hell wouldn't be easy to get off again. The Profile spindle is a little bigger.

You aren't the only one. Its a complete mess.
If you have anything other than Profile cranks, then ANY sprocket will fit... I think. (even Profile though it will be pretty loose and will be able to wobble)
If you have Profile 22mm cranks then the Profile sprocket is a very tight fit but it is also the only sprocket you should try to get on there.
Tree sprockets seem to be a third size even though they are Taiwan made too.
As you can probably imagine this is a huge headache for everyone. By doing the Socket drive we can avoid all this crap. I think our plan is to supply our socket drive sprockets with a 3/4" 19mm adaptor and then sell a 22mm Taiwan adaptor as a separate part, hopefully Profile will then make a socket drive adaptor to suit their cranks.
But for the average rider my advice would be to just buy Socket drive Thunderbolts and one of our socket drive sprockets and dont worry about any of it.

KillSeth:
Would it be reasonable for a machine shop to machine a sprocket to accept socket drive? Or is it something better suited for the actual time of manufacture?
tecnic1:
Bolt drive suddenly seems pretty nice.
