Rock II

Brand: Hutchinson

The Rock II is the mountain-bike half of Hutchinson's Rock family, a leisure tyre for hardtails and hybrids rather than for technical riding. It is catalogued in three sizes, 26x2.00, 27.5x2.00 and 29x2.00, all on the same simple build: a wire bead, a 33 TPI casing, a tubetype construction and black sidewalls. Claimed weights are 760, 955 and 900 g. The small-wheel sizes of the same family, from 14 to 24 inches, are listed separately under the name Rock.
