Notes

If the rider is still growing you may want to buy a slightly bigger size.

This is only a general guide, fine-tuning comes from experience, riding style and preference.

For safe and comfortable riding, there should be a clearance of at least 1” to 2” between the riders crotch and the top-tube of the bike.
