Hey tech question for ya-
if a 103mm BB or a 107mm BB will both work to put my Swifts Surly hub fixie chainline within 1 mm L or R of perfect center alignment, then a 105mm will get it centered perfectly? Hmm... searching web... looks like the rub is finding a 105mm BB that is affordable. Ah so.
Looks like I'll be shimming something.
My rims and Surly hubs are ordered. I plan to replace my BB when I fit the new wheels. Any reason to replace the crankset at the same time? The stock Xootr crankset and chainring seem nice enough.
I can't help myself...it's so dang easy to trick-out the Swift with different handlebar configurations.
The thing about BBs...you gotta beware of the assymetrical ones...you know, where a 107mm is actually a 105 with 2mm added to the non-drive side. For example, a 107mm assymetrical BB is the same length drive-side as a 105mm. So you're not losing spindle length on the side that counts. You get the idea. Search the web for specs on your particular BB of choice.
Plan on ending-up with several BB's until you find the one that brings joy. The golden chainline, I've found, is sometimes a hit-or-miss process.
So I assume you got the 130mm Surly NewRoad flip-flop hub with the 47.5mm chainline? Where did you order your wheelset from? I would work with the stock Tracer crankset for now, put some mileage in and get your money's worth out of it, then upgrade to a
sweet Sugino set (which is what I plan to do).
Here is an affordable BB in to use until you upgrade to a Sugino crank/BB.
