Choose the higher number (harder spring) if:

• you ride frequently in the hills or mountans
• your riding style is more power-based and you do not keep high cadence

Choose the lower number (softer spring) if:

• you mostly ride on flats and gentle rolling hills (big gears)
• your riding style is cadence based (consciously control your cadence)
