The M.C.R. 9 is built from the ground up to give you nothing short of a Magic Carpet Ride. Featuring our proprietary Reynolds 853 tubing and custom s-bend rear seat stays and chain stays, the M.C.R. 9 smooths out even the roughest of trails without the weight penalty of other steel frames.
Our proven Niner geometry uses short chain stays and a steep head tube angle to keep the wheelbase compact, making the bike maneuverable around even the tightest hairpins, while the larger wheels help to increase high-speed stability, creating a fast and nimble ride. A radically sloping top tube makes room for the family jewels and the disc-only frame means you’ll stop on a dime. Tubing is drawn out for each frame, and external, as well as internal, wall thicknesses have been tweaked to produce the best possible ride quality for each frame size. Everything about this frame was thought through, including tire clearance for fat tires and downtube clearance from pesky high fork crowns.
The M.C.R. 9 is the perfect go-anywhere bike that will keep you in the saddle and more comfortable for the long haul. The superlative quality of Reynolds 853 steel tubing with Niner-specific geometry and the stability of the 29” wheel offer a ride quality unsurpassed in any other production hardtail frame.
