How to Measure

Rider Height

Stand straight up, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

Inseam

Wearing cycling shorts, stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inseam measurement. Your inseam is very important to your final bike size so please measure carefully.

Roscoe 8 is a rowdy hardtail built to hunt for side hits and dive into the steep stuff . Its Alpha Platinum Aluminum frame pairs with a Fox Rhythm 36 fork (150mm travel) to soak up rough and chunky trail debris. It delivers plenty of gears for punchy climbs, thanks to a 12-speed Shimano Deore drivetrain, and stop-on-a-dime braking power from 4-piston Shimano M6100 hydraulic disc brakes.
