Well, I didn't plan on going here....but someone asked if I knew how to put tire sealant in a tube that had Presta valves...sort of a tricky, specialized skill, I guess. I'd just finished doing the same to my own bike, in preparation for an early spring...and somehow word got out that I'm an expert bike fixer upper. Actually, I do have lots of experience twiddling with bikes of all sorts, but never thought I could make a dime doing it. Well, I guess I can. Anyway...if you're in North Pole, and you need your bike tuned up, stop by. I can always add one more skill now that I'm sorta sposta be retired. Yeah right. By the way....the FAT BIKE was invented and developed right here in Fairbanks. I'm not the sorta fella that likes riding bikes at 50 below, but a dedicated bunch of local fatbike aficionados actually do this. I'm trying next to figure out how to operate 2200 meters bicycle mobile. STay tuned.
