The ergonomic shaping enhances comfort and thanks to an adjustable reach you can fine-tune the fit to perfectly suit your style. The BR-RX810-R Hydraulic disc brake caliper is flat mount and features an innovative anti-mud specification so that braking performance isn't hindered by poor weather and gritty trail conditions. Heat is dissipated quickly for consistent stopping power, especially on long descents, and with wheel replacement and bleeding made easy, maintenance both at home or the trail side is quick and easy.
