All you fixed gear riders who wanted to run Profile cranks, but didn’t like the wider q-factor, Profile has answered your calls. I’ve been riding their 5 1/4″ Gun-Drilled Spindle for a few weeks now and it’s so much better than the standard bb spindle. You can set them up with just a cone against the cup and no spacers now. Doing so leaves about a 3/8″ between the crank arm and my chainstay, drastically shortening the q-factor.
Grab one here at Profile Fixed under the options for spindle length.
