Box One Top Load Race Stem

Box's One Oversized Top Load Stem boasts a unique look compared to other stems thanks to their constant drive to improve.

CNC machined from 6061-T6 aluminium alloy and Cold-forged for maximum strength. Their stems are oversized for a reason, they've focused specifically on the stem-to-bar interface improving and enlarging the surface area of the stem by moving material from low stress areas.

Front-Load clamp design with 48, 53 and 60mm extensions available. Fits 1 1/8' steerer tubes and 31.8mm handlebars.
