MANTIS / XCR / 1991

Richard Cunningham originally offered the Mantis XCR as a fillet-brazed, all-steel frame in 1983, with the intention that the tighter design would be better for cross country racing. The next version with an aluminum front triangle and a steel rear end appeared in 1984 as a traditional diamond frame. The idea was to capitalize on the best traits of each material. Some time around 1989, the elevated chainstay or EC version of the frame was first offered, which solved the dreaded chain-suck problem. In addition it allowed for shorter chainstays, which quickened the handling and improved climbing. While the front ends were painted, the rears were durable, chrome plated.
