Clearance for what counts. 
Whether you need more room to make shapes or simply want more distance between the bike and yourself, the SB135 has an ultra-low slung top tube. But we didn’t stop there. To make the best fitting bike for smaller riders, we designed an entirely different frame for the small and extra small sizes. Focused on minimizing stand-over height, maximizing seat postinsertion, and preserving space for a water bottle, we moved the forward shock mount to the downtube, designed an even more compact shock linkage, and made a completely different swing arm, all unique to these two sizes. With the ability to fit riders down to at least 4’11”, the small and extra small SB135s are truly their own engineering feats within the SB135 project.

Cable management. 
Internally routed cable tubes with secure closures at entry and exit points eliminate rattles and cable rub. Whether running a mechanical drivetrain and dropper or a wireless setup, cable management is intuitively easy.

Threaded BB. 
Threaded aluminum bottom bracket shell with integrated ISCG-05 tabs. This critical drivetrain interface is now more durable, cleaner, and easier to service. You asked, we delivered

Hangerless interface. 
The Hangerless Interface creates the strongest and most precise shifting with Eagle Transmission. It’s also backwards compatible – simply thread in a Universal Derailleur Hanger (UDH) and run your drivetrain of choice.

Full drop. Full flight. 
As the capability of our bikes continues to increase, so does their ability to run modern day, full-stroke dropper posts. Our seat tube is shorter to allow for a longer dropper posts. Most riders will be able to use a 150mm dropper posts on X-Small and Small frames*, 175mm on Medium frames*and 200mm+ dropper posts on L-XL frames* for airs like this.

Speed metal. 
Gone are the days of pivot bearing on carbon contact. Our new pivot design secures 100% standard-sized cartridge bearings in the frame linkages, attached with precision-machined Floating Collet Axles ­– boosting longevity and reducing tolerance gaps to virtually zero.

Patented compact wishbone. 
The wishbone shock extender makes low slung top tubes even lower, allows us to tune the leverage ratio while maintaining kinematics, and makes shock removal a cinch. It’s driven by an all-new link that nests inside the mainframe, for a stiffer pivot ­­– and a cleaner look.

Leverage rate - 14% Progressivity.
Making turns go boom isn’t fun with your heels dragging in the dirt. But the inconvenient truth is, progressive curves don’t always help maintain composure. A straighter, more linear progression curve means it's easier to tune shocks to pair with suspension kinematics. So we chose a leverage ratio that provides small bump sensitivity and the right amount of progression to maintain mid-stroke support and bottom out control, without making it impossible to reach full travel.
