This link is compatible with the Stumpjumper EVO, Stumpjumper, and Stumpjumper ST.
Our link for the current Stumpjumper generation gives the suspension 70% more progression as well as a 5 mm travel increase (with the stock shock stroke). This allows the bike to be run with a stiff enough spring to prevent harsh bottom outs without having to compromise on small bump sensitivity or ride height. For riders on air shocks fewer volume spacers can be used to achieve the same bottom out resistance, which opens up a wider usable range for those dealing with lots of volume spacers as well. As a result, the suspension that can handle larger hits better than ever while maintaining loads of traction in rough terrain. The Stumpjumper LT link truly maximizes the bike’s descending capabilities.
The link maintains the stock ride height of the bike. In doing so, it leaves the Stumpjumper’s pedaling performance unaffected. This means all the added descending performance doesn’t come at a cost when it comes to pedaling back up.
The Stumpjumper link opens up more room for tuning as well. By making the suspension no longer reliant on things like damping, volume spacers, or progressive springs to avoid bottom outs have a larger usable range since they don’t need to be kept around a certain value for bottom outs. For example compression damping can be backed off to make the shock more active over small bumps since it no longer has to be relied on to keep the bike from blowing through its travel.
Complete Travel Specifications
|Shock size/Wheel size||29″||27.5″|
|210 mm x 50 mm||145 mm||153 mm|
|210 mm x 52.5 mm||153 mm||160 mm|
|210 mm x 55 mm||160 mm||167 mm|
|190 mm x 42.5 mm (SJ ST)||125 mm||135 mm|
We are currently working on a a table of all frame and shock combos that will provide more detail on shock size compatibility and travel amounts. Most Stumpjumper models can fit up to a 210×55 shock in high, but in low some are limited to 52.5. Regardless of compatibility we always recommend cycling your suspension with no spring or air pressure to make sure all clearances are good before riding.
