"This is the only way to setup spring shocks and it is perfect for forks!"
Kevin Walsh- Evil Bikes

Cut the O-Ring!

Slacker is perfect for setting up air or spring shocks and forks. This tool makes it super simple for anyone to quickly take real-time measurements and make adjustments with absolutely no assistance. Checking suspension sag  and health regularly and adjusting it for different riding conditions is key to getting the most out of your bikes suspension and assuring the bike is predictable and safe!  It is super easy to adjust and you will kick yourself for not doing it as a regular part of your usual bike setup sooner.

Fast, Simple, Precise-

The new and improved Slacker is even easier to use than the original! This patented system allows anyone to quickly and easily setup their bike’s suspension. Measuring sag at the shock is horribly inaccurate and does not allow for fine adjustments. In fact, I'll bet if you set your bike up once using an o-ring on the shock and then set it up again it is not actually the same travel at the rear axle because such a tiny difference at the shock is amplified at the rear axle. At 50 years old I can barely read a millimeter much less tenths! It is also impossible to tell if you sat down a little extra hard or threw it off somehow. Slacker can show you exactly how much sag you have in real-time so you can bounce the bike and settle the suspension confidently. It also allow you to see how your riding position affects the bike so you can make sure you do it the same every time. The tool was developed over the course of two years with input from industry leading suspension companies like Factory Connection, Pro Circuit, Evil Bikes and Plus3 MTB to assure the accuracy, consistency and reliability of the tool. This newest release features new hardware, new software and a fresh new look produced at a new state of the art production facility!

Includes: 1) Slacker digital sag scale with remote display, 1) universal fork and seat post adapter with velcro cinch strap and 1) 6mm hex key axle insert for downhill and XC mountain bikes. (5mm, 6mm and 8mm hex inserts are also available individually)

-Requires thru axles with hex keys to work with our MTB axle inserts. 6mm hex insert and universal fork/seat post adapter are included in this bundle.

-All measurements are shown in real-time on main unit and remote display.
-Far more precise measurements than measuring at the shock.
-Much finer adjustments are possible to get the perfect setup.
-Allows you to bounce the bike to settle the suspension unlike an o-ring.

Measurements are based on the total travel measured in reference to Slacker's positioning on the bike and directly reflects the percentage of travel used at the shock. It is far more accurate and repeatable than measuring at the shock body.

30-day Money Back Guarantee! If your bike doesn't handle better than ever you can return Slacker with no questions asked within 30 days from when it arrives.
