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.
