As you know I'm building this jalopy and need to keep the cost as low as possible. I was going to buy new cranks but I'm having issues with price and availability.
Anyway, I've been given a set of road cranks and I plan to run a single chain ring, but the BB I was given is for a 68mm BB shell and mine is a 73mm.
Have any of you guys put a road crank successfully on an MTB and / or what spindle width do you suggest I use? I was thinking about a 118mm spindle.
The net says the bike's original set up for a triple was a 113mm spindle. I read somewhere that the width difference between an MTB and raod crank is 20mm. Correct? This math is doing my head in.
