The BSD Revolution Ersatz O-Ring is a small but essential spare part designed specifically for the BSD Revolution freecoaster hub system. Over time, O-rings can wear, dry out, or get damaged through regular riding, especially in demanding BMX street and park use. Replacing a tired O-ring with a fresh one helps maintain the smooth, consistent engagement and reliable performance that the Revolution hub is known for. This simple component supports proper sealing and fit within the hub mechanism, contributing to long-term durability and reducing the chance of unwanted play or noise.
Ideal for riders who push their wheels hard with frequent fakies, spins, and technical lines, the BSD Revolution Ersatz O-Ring is a smart item to keep in your parts box. Swapping in a new O-ring is a quick, low-cost way to refresh your hub during routine maintenance or a full rebuild. By using the correct replacement part from the same brand that engineered the hub, you help ensure compatibility, preserve the hub’s unique feel, and keep your bike rolling smoothly session after session.
