Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Chainline and respacing Formula f/f hub

I'm trying to dial in the chainline on my conversion and I need to respace the rear hub, Rear hub is a Formula fixed/free with a rear CL measurement of 41mm. I need to add 6mm to the drive side to line up with front chainring measurement of 47mm. From what I've read I need to remove the rear axle & respace, but this is where I'm stuck. How do I do this?? the axle does not seem to move when I remove locknut & cone nut. Hub has sealed bearings. I've searched the forum & have not found direction. Can anyone provide some direction?? thanks!

if you respace the hub then you'll have to redish the wheel, which i wouldn't recommend unless you've got some experience truing wheels. also if you respace only one side will have a 47mm chainline. when you flip to the other side of the hub the chainline will be off.

if i were you i'd either a)run the chainring on the inside of the crank spider if possible or b)get a much shorter (~10mm) bottom bracket.
