Specifically developed for SRAM’s 120mm bolt-circle twin-ring cranks, this has specially offset teeth. They push the chainline over to centre of the standard twin ring setup, which can help with shifting and chainguide setup. Pre-threaded holes allow you to reuse your stock bolts.
We tested the smallest 36-tooth ring and, when matched with an 11-36T cassette, the gearing spread was enough for flatter rides but our legs did suffer on bigger days in the hills. Wear rate is good so far, and the shaping is good.
