DirtySixer rolls out MonsterEnduro, a 32-inch enduro bike

For years, tall riders have learned to make do with bikes that technically fit but never quite feel right. DirtySixer’s new MonsterEnduro 32 takes a different approach: instead of stretching existing designs, it builds an enduro bike around oversized wheels and proportional geometry.

The company has spent more than a decade experimenting with big-wheel bikes, starting with 36-inch concepts in 2013 and introduced production 32-inch models in 2016. The MonsterEnduro becomes the fourth model in that “point guard” category: DirtySixer’s tongue-in-cheek term for bikes sized to riders well above average height.

Built around 32-inch wheels, not adapted to them
The MonsterEnduro will be offered in sizes from L through 4XL, with the smallest size intended for riders roughly 5’7″ and up to 7’1″ and beyond. For truly tall riders, the upper sizes promise a rare chance to ride something that fits.

The bike uses the updated 32-inch Maxxis Dissector 2.4 tires. The frame is hand-built 6061 aluminum with a Horst-link, four-bar suspension giving around 140 mm of rear travel. The front fork has the same amount of travel. It’s a modest amount of travel by modern enduro standards but as founder David Folch points out, it’s logical for wheels this large. They roll over obstacles easier, therefore reducing the need for tons of suspension.

Overbuilt in classic DirtySixer fashion
Component choices lean toward durability and stopping power. A SRAM Eagle transmission drives this wagon-wheeled machine. Then Magura’s four-piston Louise brakes on 200 mm rotors provide the stopping power. The hub spacing uses fat bike standards: 150 mm in the front and 197 mm in the rear. The bottom bracket is a fat bike T47. Inboard bearings keep the Q-factor relatively narrow at 186 mm.

Up front, the prototype is running a modified Manitou Dorado fork with custom CNC crowns. DirtySixer is still finalizing the rear shock as they continue to test the bike. The geometry suggest they bike will have a a roughly 65-degree head angle and a 75-degree seat angle. The chainstays are around 490 mm.

Headed for real racing, not just curiosity status
DirtySixer plans to test the bike at the notoriously brutal Megavalanche this summer, using a squad of tall racers under race conditions.
