Description

The updated second run of the BJ frames come with thoughtful upgrades — an engraved head tube, added tyre clearance, and a T-slot seat tube for smoother, more secure QR clamping.


S&M believe 20” bikes are the original Dirt Jumpers, and giving that moniker to 26” frames blows, but at the end of the day, all that really matters is the ride. The 26” BJ is designed to go fast and high, soak up bumps and brake better than its smaller counterparts. And unlike a smaller-rigid bike, a 26” bike with a suspension fork and disc brake not only roasts transitions almost effortlessly, it leaves riders in better condition to have just as much fun the next day.

Features
  • 26" wheels, built to go big. Designed to carry speed and height, soak up bumps and brake better than a smaller bike, so you can back it up the next day.
  • Suspension fork geometry. Angles are based around a 100 to 120mm suspension fork or the rigid equivalent, with a 69° head angle and 10" standover.
  • V2 updates: tyre clearance, T-slot. The second run adds room for bigger rubber, a T-slot seat tube for smoother QR clamping and an engraved head tube.
  • 160mm disc brake mount. Comes set up for a 160mm disc using a 0mm IS to post mount adaptor, so stopping power matches the speed.
  • 135mm dropouts with tensioners. A 3/8" slot, 135mm spacing and integrated tensioners hold the rear wheel straight and the chain tight after every session.

26 inch BMX sizing

A 26 inch is the largest BMX wheel, for riders about 160cm and up, on a 22 to 23 inch top tube. It is a ride feel rather than a size step: more roll and stability, still BMX geometry.

Rider heightWheel sizeTop tube
60 to 91cm12"12 to 12.5"
81 to 106cm14"14 to 14.5"
96 to 122cm16"16 to 16.5"
122 to 147cm18"18 to 18.5"

183 to 190cm and up20"20.75 to 21.5"
160cm and up22"21 to 22.25"
160cm and up24"21.75 to 22"
160cm and up26"22 to 23"

Sizes overlap on purpose, so personal preference comes into it. A big wheel rides longer than its top tube number suggests, so do not compare it straight against a 20 inch.

How to measure

Stand against a wall in the shoes you ride in, heels flat, and mark the top of your head. Measure from the floor to the mark.

  • Choose a big wheel for the ride feel, not because you are tall. Plenty of tall riders stay on 20 inch.
  • Coming off a 20 inch? Expect it to feel longer and more stable, and slower to spin.
