I recently became curious about the answers to the following questions with respect to my fat bike, a Surly Pugsley:
1. How would it ride with a standard, not-specially-dished 26″ rear wheel and standard mountain bike tire used in the rear?
2. Would it work to mount a standard — say, 2.0 — mountain bike tire (with a standard tube) on a Large Marge rim?
3. What would happen if an Endomorph was mounted on a standard, not-specially-dished mountain bike wheel with a Surly oversized tube, and that wheel was used on the Pugsley?
Of course, I had theories but I wanted some observations by way of confirmation. So I set out to do some experiments.
