The CEMA SRC-HS-JS09 is a sealed cartridge headset bearing sized 41.8 x 30.1 x 6.5mm with a 45°/45° contact angle, built for 1-1/8" headset applications. It's a direct cartridge swap for a worn or notchy headset bearing of this exact size — no adjustment, no races to press, just drop it in.
Manufacturing defects are covered under CEMA's warranty terms. Return the bearing to Tune Cycles and we'll manage the claim on your behalf — no need to contact CEMA directly. This is in addition to your rights under the Australian Consumer Law.
