The Sentinel LT link completely revamps the bike’s suspension. By increasing the progression from 7% to 20% it provides much better small bump sensitivity, mid-stroke support, and bottom out resistance. As a result, it maintains traction much better, feels more composed through chop, and has way more bottom out resistance. Essentially this link gives the V1 Sentinel the suspension performance of a V2. Whether it’s pinning it through roots and rocks, sending it to the moon, or railing berms, this link will make the bike feel better than ever regardless of whether you are running the stock shock or the most top of the line options out there.

At 20% progression, the Sentinel LT link plays well with shocks like the stock air shock as well as coils. The benefits of running the link with the completely stock shock alone are substantial and no shock modifications are required. If you are running a coil or thinking about it, this link is hands-down the way to go. The improvements this link provides far surpass what’s possible with volume spacers or damping tunes. It’s no wonder Transition is implementing similar leverage curves with their newest bikes.

For those riding the bike for more gravity-oriented things, the Sentinel LT link also brings an increase in travel. With the stock shock size, travel is increased to 146 mm. The carbon frame has more clearance and can run up to a 205×60 mm shock for 152 mm of travel. This allows the bike to be set up as 160/152, which is more in line with current enduro bikes out there. For the time being this is the Super Sentinel.

A note on shock compatibility…

Please check your shock stroke before installing the link. This is the distance between the shock body and the surface on the spring retainer/clip that the bottom out bumper rests on. We have encountered shocks where the stroke is significantly more than it should be. There will be clearance issues if your stroke exceeds recommendations.

Some carbon Sentinels can run a 205×62.5 mm shock for 158 mm of travel, but not all. If you do decide to run your carbon Sentinel with 158 mm of travel, please check all frame clearances at full bottom out. While it works on our test bikes, we’ve seen enough variation in carbon frames from other brands where it’s a wise idea to check. The area to pay close attention to is the clearance between the shock reservoir and the frame. It clears on the DHX2, but longer reservoir shocks may have issues here.

Sentinel Mullet Set up

The Sentinel can easily be converted to mullet bike that maintains the stock geometry by installing an 8.5″ (216 mm) eye-to-eye shock and limiting the stroke to 58.5 mm. The standard stroke for an 8.5″ shock is 2.5″ (63.5 mm) so a 5 mm travel reducer is what’s needed to limit the stroke properly. If you are converting your Sentinel to a mullet set up by using this shock size we highly recommend installing our link because the stock link is -6% progressive with the shock.

Set Up FAQs

No change to the shock is necessary. Even with the completely stock shock the improvements will be very noticeable.

Both can work well with this link. We prefer the coil for rougher trails with lots of roots and rocks and air for trails that are smoother but with big hits. If you already have something installed on your bike and don’t feel like replacing it there certainly isn’t any reason to.

This link delivers substantially more bottom out resistance than the stock link. Using 30% sag should be your starting point. If you feel you need a little more first try adding a few clicks of damping to account for the change in leverage curve. If you still want even more you can try going up 25-50 lbs in spring rate or 10-20 psi in pressure.

At 30% sag this link will also deliver much better small bump sensitivity so start there. If you still feel like you’d like a little more try running less damping. The link makes it so the suspension doesn’t rely on damping as much to avoid bottom outs so running less isn’t an issue.

The link doesn’t change the static geometry of the bike. The only geometry affected is wheel position at full bottom out.

Installing this link does not void your frame’s warranty. Thank you Transition for being open minded to these kinds of alterations.

Recommended Spring Rates

Recommended sag at the shock is 16-18 mm. This equates to 28-32% sag at the wheel. Note that because the link is more progressive it sags a larger percent at the wheel than it does at the shock. It is not advised to run more sag than this because the bike will sit in a region of its travel where anti-squat is lower. This link does not require excess amounts of sag to achieve small bump sensitivity. Please set your sag at around 17 mm at the shock and let the link do its work. The spring rates below should get you close to the right sag but you might have to deviate from them here and there.
