About 3T Alloy Apto Pro 80mm Stem

If you see a stem with blacked out logos in the pro peloton, it’s likely to be a 3T. Why? For the same reason bike fitters love it - we make our stems available in a very wide range of lengths (70-150mm), angles (+/-6 & +/-17) and levels. The stem may not be the most exciting bike part, it is the crucial connection between frame and handlebars ensuring the bike handles well and your body is in the right position. The Apto continues 3T’s six decades of leadership in stem design, combining unparalleled functionality with Italian elegance.
