Your elastomer will also depend on your riding style, terrain and other factors. If you ride on rough terrain or ride
aggressively, you may benefit from a harder elastomer. If you are a leisurely rider, who rides predominantly on smooth
tarmac, you may be able to use a softer elastomer. Note: you may need an elastomer that is one grade harder if you are
carrying any significant load.
If you are a light rider and have your suspension setup soft it is advisable to adjust it to a firmer setting and change for a
harder elastomer if necessary before allowing a significantly heavier rider to sit on your trike, otherwise permanent damage
to the elastomer may occur.
