Since 2005, Mortop has been obsessed with three things: weight, precision, and durability. Born in Taiwan and trusted globally, we provide riders, distributors, and cycle parts shops with elite-tier components, including bottom brackets, headsets, wheelsets, tyres, and grease. Whether you are looking for advanced material solutions or essential spare parts, Mortop delivers the performance you can feel.
Real performance is best proven in real riding. Mortop ambassador Emanuele, an experienced Italian cyclist, tested the Spinning BB over nearly 3,000 km in outdoor and indoor training. He praised its smooth crank rotation, solid feel, quiet performance, and reliable durability under repeated sprints, climbs, and hard efforts.
