MTB Pro Kit

Great tool for tuning MTB suspension

High quality kit with everything you need to accurately set the sag on the front and rear shocks. I was surprised at how far off it was using weight formulas to estimate shock pressure to set sag. After setting the correct sag with the slacker, my bike rides so much better—more active on climbs and plush on the descents!

Makes Setting Suspension Straightforward & Consistent

The Slacker made it easy to measure the sag on my mountain bike. It allows me to take consistent measurements over time and make adjustments as necessary. I found the sag on my rear suspension was way too much.

Fills in the gap

I have been looking for a tool to measure sag for coil-sprung shocks, and some of the existing solutions are too complicated to use, in some cases one must remove the shock from the bike to install the tool. Slacker’s approach is completely different, it measures the sag without removing anything from the bike and I find it interesting that the measurement is done at the axle instead of the shock itself. So far, I’m satisfied with the tool, how easy it is to use, and I think the measurement is more adequate.
