Rider-matched picks
Size-matched helmets picks for long torso riders, with fit and feature priorities curated for how long torso riders actually ride.
Open the helmets calculatorLong-torso riders typically need 15-30mm more reach than standard sizing suggests for their height. You may need to size up one frame size for adequate top tube length while using a shorter seatpost or setback post to maintain correct leg extension. Look for frames with longer effective top tube lengths relative to seat tube length — brands like Trek and Canyon tend to offer longer reach geometry. A longer stem (100-130mm) can add reach, but don't compensate more than 20mm with stem length alone, as it changes steering responsiveness. Measure your torso by sitting on a stool and measuring from the seat to your sternal notch — if this exceeds 60% of your inseam length, you likely have a long torso relative to legs. Consider frames with sloping top tubes that provide adequate standover while allowing a longer effective top tube. Dropped seatposts with less setback help keep weight distribution balanced.
Measure head circumference at the widest point across the forehead. Most brands size: XS (50–53 cm), S (53–56 cm), M (56–59 cm), L (59–62 cm), XL (62+ cm). Kids helmets typically start at 47–50 cm. Always try before buying; fit varies by brand.
