This video shows how to determine whether your shocks are bottoming out too often, then discusses how to adjust the suspension preload to tame your ride.
After considerable cogitation then applying some highly speculative assumptions, I drew an XY graph that estimates suspension preload settings by rider weight. The number of clicks count from minimum preload. Your Rebel 1100 comes from the factory with preload already set to three clicks.
Here are my assumptions
* Engineers selected a spring preload with a maximum preset of 18 at or near the 348-pound maximum load limit of the Rebel 1100
* Engineers selected a factory preset of three clicks assuming an average rider weighs about 170 pounds.
* The relationship between the number of preset clicks and rider weight is mostly linear.
Assume these settings are my best guess. You should do the zip-tie test to determine your preferred preload settings.
Preload "Clicks" from minimum preset by Body Weight in Pounds
Weight Clicks
100-122 0 [Who weighs that?]
125-149 0
150-174 1
175-199 4 [Papa Steve now]
200-224 6 [Papa Steve when I made the video. It was 5 clicks actually. I weighed 210]
225-249 9
250-274 11
275-299 14
300-324 16
325-348 18
