Geometry tweaks can transform the way a bike rides, and the Riser Crown Race makes those subtle changes simple. Designed by Mountain Racing Products, this clever little component comes in two options-5mm LowRise and 10mm HighRise-and installs like a standard crown race while giving you more front-end clearance and a touch of geometry adjustment. Ideal for gaining room for oversized fork crowns or upgrades like the Noken air spring, the Riser Crown Race is compatible with any 1. 5-inch headset using 36/45deg bearings. Expect a 0. 25deg or 0. 5deg head angle change depending on the model you choose, letting you slack out the front end or tailor fitment on modern enduro or trail bikes. It's one of those small tweaks that has a big impact on ride quality and fit.
