The 3T Apto Pro in a range of lengths is an affordable high-quality road bike stem to experiment with your riding position.
If you see a stem with blacked out logos in the pro peloton, it’s likely to be a 3T stem. Why? For the same reason, bike fitters love it. 3T make stems available in a very wide range of lengths (70-150mm), angles (+/-6 & +/-17) and performance levels. The stem may not be the most exciting bike part, it is the crucial connection between the 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.
