Specifically designed for Challenge Seiran bikes, the ultra-durable T-Cycle Challenge Seiran Easy Reacher Rack is custom made and comes much stronger than an ordinary rack. Mounting arms are custom CNC machined for each main frame tube and chainline with black anodized TIG-welded rack arms. Racks are further customized with pannier rail levelling clamps specific to the angle of your main tube. Once you see how beautiful these parts are you will appreciate the all USA made T-Cycle rack. No other rack system is anything like it.
