This exceptional versatility ensures a clean pathway for your brake and shifter cables, hiding them from the wind to reduce drag and create a sleek, aesthetically pleasing front end. This stem provides the clean integration that high-performance bicycles demand. Built for universal compatibility, its 31.8mm bar clamp diameter works perfectly with the vast majority of standard road, time trial, and triathlon handlebars, making it a straightforward yet powerful upgrade for your existing setup.
Crafted from high-quality Aluminum, the Profile Design Tri stem delivers an exceptional balance of stiffness, strength, and sensible weight, ensuring precise, responsive handling when you´re in the aerobars or out of the saddle.
