The ORBEA OC1 MTB Crank Preload Bolt and Tool is a small but essential component designed to keep your mountain bike crankset running smoothly and securely. This preload bolt allows you to precisely set the bearing tension on compatible OC1 MTB cranksets, helping to eliminate unwanted play and creaks in the bottom bracket area. By maintaining the correct preload, you protect your bearings from premature wear and ensure a more efficient power transfer every time you pedal.
Included with the bolt is a dedicated tool that makes installation and adjustment straightforward, even for home mechanics. The tool is shaped to engage perfectly with the preload bolt, allowing you to dial in the correct tension without damaging the part. This combination is ideal for riders who regularly service their bikes, swap cranksets, or simply want the peace of mind that their drivetrain is correctly set up. Whether you are building a new ORBEA MTB or refreshing an existing one, the OC1 MTB Crank Preload Bolt and Tool is a smart, low-cost upgrade that supports long-term reliability and consistent performance on the trail.
