S36 is the postcode area of Sheffield's infamous Wharncouver, the place where serious riders come to test their metal on the man-made berms and bumps, tracks and jump that criss-cross down the steep sided hills. It's also the name of our latest downhill bike.

  • 650b Downhill Bike
  • SRAM GX1 DH groupset
  • BoXXer Charger RC, Kage RC suspension
  • Progressive geometry Full Description


The first On-One S36 magazine review is in and Factory Jackson simply love the S36 stating that "The On One S36 is a machine a bloody fun bike that just pushes you to go that bit faster and bigger." What more could you want from a downhill bike?

Sheffield's Wharncouver is littered with interconnected trails that slice down the steep sided hills, threading through trees and over man-made features that are designed to test the metal of the very best riders. Hidden away in the trees these sneaky trails are where you'll find the hardest-riding, most enlightened downhillers and it's the natural home of the S36. Born and bred in Sheffield the S36 has raced at Steel City, flown over the table-tops on DH3 and covered every inch of Wharncouver's trails.

Frameset: The S36 packs in 8" of progressive travel and doesn't mind whether you prefer a coil or air shock. With a low centre of gravity, long cockpit and slack head angle the S36 is perfect for blasting the steepest trails and grabbing massive airtime. 650b wheels are the perfect compromise; fast rolling, agile in the turns, they help serve up huge amounts of confidence so you can pin it to win it.

An ISCG 05 mount helps protect the low-slung BB giving you the confidence to push harder in the rough stuff. Designed for SRAM's new 1X drivetrains the S36 uses an 83mm threaded BB shell and 157x12mm back end to give you perfect chain line and the smoothest transmission possible.

We've sweated the details so you don't have to. Oversized bushings and burly shock mounts help ensure maximum service intervals. A massively reinforced head tube supports an oversized tapered headset for effortless steering control and load distributing frame gusset protect your investment.

Groupset: SRAM GX1 DH incorporates the same Championship-winning SRAM 1X technologies as their German-engineered, industry-leading X01 DH drivetrain, GX DH delivers dedicated, gravity focused 1x performance that doesnt break the bank. GX DH is a no-brainer for any rider ready to attack the next DH run. With its main objectives being durability and dependability, GX DH is the clear choice to bring more riders to the mountain, and the one to keep them coming back for more. GX DHGet Some.

Suspension: RockShox BoXXer Charger RC fork and Kage RC shock. For nearly two decades, BoXXer has been piloted to the top step of the podium at downhill World Cup races and freeride events more than any other fork. With such a legacy, its no doubt the new BoXXer has already proven itself. Now it comes with the full Charger damper kit upgrade ready fitted, the BoXXer Charger RC is ready to take you places. RockShox's Kage RC rear shock serves up 75mm of stroke for 8" of supremely smooth and well-damped travel. With a progressive curve and RockShox Dual Flow Adjust damping the Kage RC gives you all the adjustment you need. External dials for compression and rebound let you rig your S36 to ride just how you like it.

Wheelset: WTB Frequency i29 on EL Guapo Sidewinder hubs. Tough and tested rims from WTB laced to our massively strong Sidewinder hubs. With oversized 17mm axle, sealed cartridge bearing and burly freehub body this is a wheelset you can trust.

The S36 is designed for riders who go fast and go big. Whether you're maxing out the shuttle runs, a season's lift pass, or simply smashing it down the tracks and pushing back to the top- do it all with the S36.

Please Note: All customisable options will be fitted by our trained mechanics.
