Dawes SST bottom bracket specs and chainline question
So I have recently replaced my rear wheel. I have a Paul hub on it the rear wheel and added some Sugino RD2 cranks. However, I am now getting some noise and my chainline seems to be a little out of whack. I was wondering if anyone else had a similar experience. Also does anyone know the exact specs of the Dawes SST bottom bracket. Is it a truvativ? Is it 68x 103 or 108. This chainline thing is bugging me and I am trying to figure out the cheapest most effective solution.
Thanks
Thanks

Take off booth crank arms and measure the spindle. A vernier caliper would make is super easy to find the measurement. Try the chainring on the inside of the crank.

i think paul hubs have a 46 mm chainline instead of the track standard 42. If i remember correctly from where i read that you can chagne it by flipping the cog or something like that.
edit: I just checked the paul site and its 44mm

I think the RD crankset is 45mm chainline and the Paul's is 44mm chainline. Assuming chainline variance is not the issue here, it might be the profile of the chainring teeth which is causing more noise. Some rings/cogs are noisier than others.

damn...108 so that might b where the problem lies. i think the suginos are supposed to create something like a 45mm chainline and the paul hub supposedly a 44mm so that is a wash. I supposed it might b bb related then. But it seems a good deal of the actual noise is coming from the cog as well. By the way are you guys actually capable of measuring to the mm with nothing more than ur eyeballs and measuring tape as your guide? I find it to be very difficult.
