Description

S&M believe 20" bikes are the original dirt jumpers and that handing that name to 26" frames blows, but at the end of the day all that really matters is the ride. The 26" Big Jumper is designed to go fast and high, soak up bumps and brake better than its smaller counterparts.

Unlike a smaller rigid bike, a 26" with a suspension fork and a disc brake roasts transitions almost effortlessly and leaves you in better condition to have just as much fun the next day. Geometry is based around a 100 to 120mm suspension fork or an equivalent rigid fork, with a 120mm head tube that takes a 1.5" tapered steerer.

Features

Built around a 26" wheel. Designed to go fast and high, soak up bumps and brake better than its smaller counterparts.
Geometry set for 100 to 120mm forks. The angles are drawn around a 100 to 120mm suspension fork or an equivalent rigid fork, so the bike sits right.
Tapered 1.5" head tube. A 120mm tall integrated 42/52 style head tube that accepts a 1.5" tapered steerer.
160mm disc brake mount. Real stopping power for going fast into jumps, using a 0mm IS to post mount adaptor.
Four colourways to choose from. Raw Dog gloss clear, Limousine Black, the transparent dark maroon-red Satan Red and dark trans green Gangrene.
