Been toying with the same idea. The SS freehub body is narrower so the wheel has less dish (stronger) and it improves chain clearance for big tires. There's indeed quite a few threads on MTBR, here's a fewhttp://forums.mtbr.com/29er-bikes/6-spe ... 73783.htmlhttp://forums.mtbr.com/29er-components/ ... 58083.htmlhttp://forums.mtbr.com/29er-bikes/6-spe ... ost4788277
this link is a very detailed guide with numbers for cogs and spacing data:http://www.peterverdone.com/wiki/index. ... _Speed_MTB
My aim is not actually creating a big range, rather an SS with "options". I like SSing, when I go out on my own or with my 11y old son it is always on a Singlespeed. I'd like to take it out on the sunday morning group ride too if it wasn't for the fast farmers tracks connecting the proper trails. All I need is a few gears for a more manageable rpm at say 30ish kph (20mph). I know I could also stretch to lighter climbing gears, but hey, Holland IS flat.
Compared to my typical 38x 19/20 SS gearing I would go for a 14-15t smallest and then build it to 20something in 4 steps? 14-16-18-21-24? I can do 8v or 9v spacing, thumbie or trigger and I don't need the 6th cog, maybe a 14-17-20-24t set would do the trick with 4 speeds. Quite a dedicated set-up, purpose built for my local tracks. Now looking to assemble something close to this without reverting to all individual cogs and spacers.
