Did you end up running discs on the front? hows it handle?
I'm running GP4000's also in the 28mm, but theres about 1mm clearance between the tyre and the bottom of the fork so it rubs sometimes....looking at your pic above there seems to be loads of space?
building up new wheels so that I can run a front disc on it. Hope pro4 silver front hub, silver dt comp spokes and the new open pro disc rims.
for a rear wheel i'm trying to justify a phil wood, but it's kinda hard.
Need to be a fixed/fixed hub in silver. 32h
suggestions?
