Orbea's line of MX bikes is especially innovative. With lots of technological concepts and details put into the design, the results are bikes that are not only capable but also really fun to ride. Each MX is loaded with features that help ensure longer life: a durable aluminum frame, sealed headset and bottom bracket bearings, and a replaceable derailleur hanger. The AL6061 frame tubing of the MX is carefully shaped and manipulated to put strength where it's needed while reducing weight where possible. MX only uses hydraulic disc brake systems because of their power, reliability, and low maintenance. Their improved lever feel and increased stopping power will make your rides safer and more fun. Internal Cable Routing not only gives a cleaner appearance, but it also takes advantage of full-length cable housing for great performance with lower maintenance. MX is compatible with your riding style--the patented Orbea Digit quick-adjust seat post fits perfectly, and mounting points for racks make increasing carrying capacity a breeze.
