Also, put any items you carry in/on your bike in place as well–this includes water bottles, and items in your Glovebox internal storage compartment. Make sure you’re dressed in your riding kit and gear-sag is very sensitive to weight, so if you normally wear a pack filled with water, strap that on along with your helmet and riding shoes before you jump on your bike. So grab a ruler and we can get started.Ģ. You know that little rubber band-looking thing on the shaft of your rear shock? It’s an o-ring, and it's used to measure your sag. That’s all fine and dandy, but how do you get this number for your rear shock? 1. Compression damping controls how fast the suspension can compress, or essentially, how quickly it can respond to an impact, while rebound controls how quickly your suspension recovers from an impact. Further, it also controls the way it compresses during impacts-faster = less damping, slower = more damping. The damper is what keeps the spring, whether air or coil, from sending us over the bars every time the suspension rebounds from an impact. Damping is what controls your suspension by adjusting how oil moves through the valves inside of your suspension. Sticking with the Hightower example, it features a 210 x 55 shock-55mm of stroke and 210mm of total length.ĭamping – All suspension (forks and rear shocks) has two basic components, a spring and a damper. Shocks are measured by total length (eye-to-eye) and stroke (travel on the shock). Knowing how much stroke your shock has is important because it will let you translate a percent of recommended sag to an actual number you can measure. While a Hightower, for example, has 145mm of rear travel, the shock only has 55mm of stroke. Shock stroke – For a rear shock, Shock Stroke measures how much total travel in millimeters that your shock has–which is different than how much travel your bike has. If you're running a coil shock or fork, it's adjusted by changing out the spring itself for one with the correct spring rate, which is measured in pounds. With an air shock, it's adjusted by increasing or decreasing air pressure. Why does that matter? Because this utter fanaticism for our product makes us the best at what we do - We live to create cyclists.Sag – Sag is the amount suspension travel used with just the rider's weight on the bike. We only sell bikes - you might even say bikes are our life. We don't sell snowboards, we don't sell kayaks and we don't sell tents.

Why shop with us? Because we know bikes and we care.
