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 a rear elastomer that is one grade harder if you are carrying any significant load; front
elastomers are not affected much by the load on the rack or carried in bags. Elastomers do not significantly
change stiffness with lower or higher temperatures, and you may find you prefer to change to a softer
elastomer in cold weather.
If you are a light rider and have your suspension setup soft it is advisable to adjust it to a firmer setting;
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.
