An integrated headset for frames whose bearings drop straight into the head tube: a 42 mm upper and a 52 mm lower bearing, both 45x45 (IS42/28.6, IS52/40). The patented GripLock cap sets preload separately from the stem clamp, so it goes on to a torque spec and stays there.
Compatible with Open, 3T, All City, Low, Cinelli, Lynskey, and more.
Compatibility questions: send the bike's make, model and year to support@dragonspinecycling.com and we will confirm the right part before the order ships.
