More about e*thirteen MTB Stems

Engineered to vanish when you're riding. Designed to turn heads when you're not.

Off.Road.cc called the Plus 35 "a tough little unit" and "my favourite one to date," noting "the steering felt spot on. There was no twisting feeling and no issues with bolts loosening." MTB-MAG put it through "pretty decent slams and crashes" and found the bar stayed put where they "fully expected it to be cockeyed."

Plus 35 is machined from ultra-strong 7050-T7 aluminum with a two-tone anodized finish. The 132° opposing steerer clamp bolts deliver optimal knee clearance while maintaining alignment as you torque them down. Available in 40mm and 50mm lengths with color options to match your build: Bronze, Naranja, Eggplant, and Intergalactic.

Base 35 delivers the same technical benefits in a no-nonsense package. MBR found it "solid and responsive" with bars that "haven't moved a jot over months of riding." Forged and CNC cut from 6061 alloy with low-profile T25 hardware and convenient bar angle indicator markings.

Covert I.C.R. Core takes E-MTB cockpit design further with internal cable routing. A seamless pathway runs your control cable through the handlebar, stem, headset, and frame for a clean look and added protection against snags and crashes.

Every stem features 35mm bar clamp diameter and Grade 12.9 T-25 hardware built to withstand years of aggressive riding.
