The parts maker 3T has been making bicycle parts since 1961. Originally named 3TTT for Tecnologia del Tubo Torino (Turin Tube Technology), the firm began by making steel handlebars. By the 1970s 3T products had switched to light alloys and were very well regarded. They are used by many top-end bike makers and successful pro riders.

3T's Mutant stem:

• In 1999, the Mutant racing stem became the first bicycle stem ever to be recognized with an International Design award for innovation
• Forged AL 6082 T6 aluminum alloy
• 26.0mm bar clamp diameter
• We have Mutant stems in both 1" & 1 1/8" (with adapter sleevers for 1")
• 10-degree rise
• Produced in the 1990s
