Pugsley Upgrade I want to upgrade the Pugsley. I don't know if it is really an upgrade or not, but there are a couple of things I want to change. First I want to either rebuild or replace the rear wheel. I want to make it into a 9x1, sorry single speeders. That means I need a new rear hub or entire wheel. As well as a rear deraileur and shifter. If a new wheel is the way to go I want to try the new extruded Large Marge XC rim from Surly. Not sure on the hub yet. For the shifter I'm thinking of a Paul Components thumbie paired with a 9-speed shimano bar end shifter. For the rear deraileur I will use the 9-speed XTR off the 8000. I also thought about going with the White Industries Dos ENO freewheel, but it doesn't come in a big enough gear. I'd need at least a 22t. Any other ideas?
