3T Cycling Apto Pro Stem

Joining frame and fork, the stem is perhaps the most critical juncture of your bike when it comes to controlling. Designed, forged and moulded to provide an outstanding level of strength without superfluous material or overcomplicating the issue, the 3T Cycling Apto Pro Stem is made from aluminium 6061 for a supreme strength-weight ratio.

With chromoly bolts reinforcing this stem and offering a secure connection between bar and stem, this stem clamps to handlebars using the 31.8mm modern standard diameter. Providing a 40mm stack height and a 6-degree rise, this stem is ideal for any rider looking for comfortable positioning, and available in lengths up to 130mm, you can be sure of finding your reach somewhere in your machine.

Weighing just 164 grams in a 110mm edition, this stem uses steerer diameters of 1-1/8" and is sure to deliver a better feel and freedom of movement out on the road as you tick off your ride goals.
