Our Hightower mullet link is designed to preserve geometry as best as possible when running a 27.5″ rear wheel. The link raises the BB height 12 mm relative to running a 27.5″ wheel with our standard link. While this is still a little lower than the stock geometry, it’s as far as you can stretch it with only one link and not compromise the kinematics. With sag set properly, we have found pedal strikes are no more of a concern than they otherwise are.

Along with the geometry modifications, our Hightower mullet link increases bottom out resistance. The link is slightly more progressive than the stock link, but not quite as progressive as the standard link. Increased bottom out resistance is accomplished by the increase in initial leverage ratio. This increase in initial leverage ratio is what pushes the travel to 155 mm as well. Technically, our Hightower mullet link is a little more resistant to bottom outs in drop to flat scenarios than our standard link even. Initial leverage ratio controls bottom out resistance in these situations while progression controls it for impacts that occur while the wheels are on the ground.

Set Up FAQs

No. This link is only compatible with air shocks unfortunately.

Air pressures are set to sag around 30% while also increasing bottom out resistance over the stock set up. For increased bottom out resistance starting with the recommended shock settings is a good starting point. If you find yourself wanting even more try adding four clicks of LSC. If that’s still not getting you there installing the Megneg is a great option. If you are running 30% sag with the Megneg and can bottom it out easily your shock likely needs to be serviced.

Sure

Longer chainstays will make the bike more stable at speed especially through rough terrain. They also make it harder to wheelie out while climbing. However, at +5 mm the added chainstay length won’t be noticeable unless you think specifically about it while riding. Contrary to popular belief they actually can help with cornering by distributing a little more weight to the front wheel.

There is not a grease port on this link. We have found that by the time the bearings need greasing they also usually need to be replaced. We chose to go with sealed Enduro MAX bearings and forgo the grease port because the bearings will last longer in harsh conditions. The bearings are the same size so you can still use the Santa Cruz lifetime bearing replacements, but they just won’t be sealed.

These pressures are recommended starting points for tuning your shock. The desired amount of sag is still 30% so adjust accordingly.

Please note this link has not been confirmed to fit XXL frames as they have slightly different pivot locations. If you have an XXL frame and are interested in the link please email us for details.
