The Sentinel Carbon frameset is the perfect canvas to create to your ultimate custom build. The all carbon construction including carbon rocker arm makes this bike very lightweight, durable and stiff in all the right places. For rear suspension, we worked tirelessly with Fox to create the perfect tune with the extremely impressive DPX2 rear shock. Amazing small bump sensitivity like a coil shock and excellent mid-stroke support and bottom out control. The Sentinel Carbon Frameset features a threaded BB, external rear brake routing for easy brake maintenance, full water bottle storage inside the main triangle, boost rear end and rubber molded frame protection.
