The HX1 is reminiscent of CHUMBA's long-standing heritage - dialed geometry, simplicity, elegance, and outstanding craftsmanship using only the highest-quality materials. The HX1 is a tough trail bike built around a five inch fork. We've designed it with a sleek ultra-light eccentric bottom bracket for easy disc brake use - and it can be set up as a single speed or with gears. We also offer a replaceable derailleur hanger. Set it up as a rigid single speed or a trail bike with five inches of travel. The HX1 reveals the performance and beauty of a world-class hardtail.
