Suntour Cyclone Cranks ???

Hi,

Three related questions:

1) Does a Suntour Cyclone crank need the same taper bottom bracket spindle
(ISO) as does a Suntour Superbe Pro crank, or can the Cyclone use a
"standard" JIS taper spindle, such as a Shimano?

2) And, no matter the taper, what length bottom bracket spindle does a
Suntour Cyclone need?

3) Does anyone know some good online sources for tech info, such as this
question about the Cycline crank, for Suntour parts in general?

Thanks,

David

Normal, not Shimano. Same as all classic cranks and current
Campagnolo.
Suggested spindle for a Cyclone 400 is a 3-K, asymmetric
with a 33.5 right side.

For a Cyclone 7000 it's a 3-H. That spindle is symmetric
with a 30.5 on both sides, 113mm overall. If that's the
crank you have I would be more inclined to try the
Campagnolo 111 than the 115. You can always add a small
spacer under the right side if needed.

I don;t have much on the crank tech but we do support
