I will try to make this understandable. I have a set of GL330 Mavic wheels with Shimano 600 hubs (i did not build, got 2nd hand). The freehub body holds 9 speed with a 1mm spacer on the hub.
The axle on the rear appears to have 2 spacers on the non drive side, i had a hard time getting my calipers in there, but it looks like 3mm (one looks thicker than the other, but 3mm would get 126 to 129, seems a bit off). I have been reading about adding spacers to 126mm to make 130. Anyhow, i am going to build up a 2nd set of wheels that i can use as pit wheels and that my wife can use on her 9spd bike.
I will look for some Shimano 600's so that I can dupicate this setup, but if i were to go with tiagra or 105's, will my wheel dishing be all screwed up so that i cannot easily swap wheels back and forth?
If i were to find some stock 130mm wheels and the RD still shifted OK, would it be safe to say that i could build up some standard 130mm hubs on my next set and all will be well?
I hope this made sense
CLIFF NOTES: Shimano 600 rear hubs have 2 spacers on non-drive side, want to build up a set of pit wheels, but am worried that dish/axle spacing may be screwy for shifting/brakes
