3T Apto Stealth Stem +/-6 Degree Info
The 3T Apto Stealth Stem +/-6 Degree is a clean, no-nonsense alloy stem built for riders who want a reliable fit without unnecessary weight or complexity. Machined from 6061 aluminium, it delivers a stiff, direct connection between fork and bar — the kind you feel in your handling, not just on a spec sheet. The matte black finish keeps the cockpit looking cohesive on any build.
Available in seven lengths from 70mm to 150mm, the Apto Stealth gives you real flexibility when dialling in your position. The +/-6 degree angle works with a traditional round 1-1/8" steerer — note this is not compatible with D-shaped steerers — and the 31.8mm clamp fits the vast majority of road handlebars. Weight runs from 127g at the shorter end to 180g at 150mm, keeping the overall package honest for an alloy stem at this tier.
