Hi all,
Thank's for all the great comments. The wheels I am running with the Hookworms are a sun fat albert, unfortunately they discontinued the rim. Felt bicycles has a rim that is the same width and a very similar profile that I have been tempted to try. As far as the fitment goes they were tight on the bike. I had to rais the fenders a hair and shim the wheel a little to. You will have to check your frame clearance at the front of the rear tire, some bikes have a good gap and some are very tight with the stock tires (evidently there was two different jigs where the bikes were manufactured). If you have the larger gap you will only have to do minor changes.
There is another tire that is 26x2.6 and looks like the old brick tire that a guy brought in yesterday but for the life of me I can't remember the manufacture. I will try to get some info on those in the next few days.
