The ASC Pro Tilt Wedges are available in increments of 1°, 2°, 3°, 4°, and 5°, allowing precise adjustment of the ASC Pro’s default 15° angle to match the rider’s fit. The wedges come in both positive (+) and negative (-) angles, enabling the base 15° angle to be increased or decreased. For safety, the total adjustment range is limited to ±10°, meaning the maximum achievable angle is 25°, and the minimum is 5° The ASC Pro includes a switch adapter that reduces reach by 20mm when the brackets are flipped. Note that using the switch adapter reverses the wedge angle. To ensure proper fit, it’s essential to know your reach before purchasing wedges. If uncertain, consult a professional bike fitter.
