shimano/suntour compatibilty

[Elev12k]

Hi,

I do have 8s Suntour XC Pro thumbies on both FAT and Panasonic.

On the Yo with Kooka crankset with Kooka rings and 8s XTR ti cassette (that makes m930?) and ’96 grey XTR mech. Excellent performance.

On the Pana XT m730 cranks and rings, m730 mid cage mech and 7s XT cassette. Excellent performance.

In index mode.

The Suntour Thumbies will work with shimano 7-8 speeds. The window of adjustment will be narrow, but it can be dialed in quite well. There were many weight weenie bikes and builds published in magazines back in the day that ran the combo due to the feathery weight of the Suntour thumbs.

Also to chuck another related (hoping non-thread hijack ) question into this - how would a SRAM road cassette work on a current 8 speed Suntour MicroDrive system? Would the cassette even fit onto the hub?

Iirc Suntour MD had a completely different spline system to anything that's Shimano compatible.

In fact I've just checked my XC Comp hub and the splines are a lot finer than Shimano's. So the answer is no.

As long as the dérailleur and cassette are both Shimano units the Suntour thumbies ought to shift them fine (as bore out by the accounts provided above). Shimano and Suntour thumbies pull virtually the same amount of cable per index click, so the key consideration here is that the dérailleur throw needs to match the cassette cog spacing.

Glad you guys are around!

I was about to put 7-speed Shimano shifters on my friend's bike with a Suntour 7-speed group.

The bike has Suntour '7s' under-the-bar shifters. They're strange and starting to lose their index ratchet powers. (I guess Gen 1 Rapidfire sucked too!) Oh well, it's a $30 bike.
