I bought the 27.5x2.10 tube for a mountain bike tire knowing that it might be a little small, which it was. Fortunately, I had a previous foam insert for the previous tire, and coupled with this tube, fit in the tire snugly. It was a bear to get them seated in the tire and rim, but they have remained in place throughout the past year, and of course no more flats to worry about. I have gotten use to the firm ride, and the foam insert provides a little more cushion than the yellow tube alone might otherwise provide.
