Engin Cycles 35mm Stem

Engin Cycles



The all-new Engin 35mm Stem is a premium component designed to meet the exact standards of modern mountain bikes. Each stem is produced from domestically sourced 6061 Aluminum and machined in house in Philadelphia. Every threaded hole on the Engin Stem is form tapped to increase strength and longevity over standard cut threads. 

One major hurdle to clear in the development process was ensuring a tight fit and secure clamp with a wide array of handlebars and fork steerers on the market often having slightly varying clamp diameters from the nominal measurement. In order to accommodate the most bars and forks possible, we went through a painstaking process of refining the bore sizes on our clamps to ensure the best possible fit on any bar or fork you could choose to use with our stems. This means you won’t need to resort to over-torquing fasteners to firmly hold your components, which is a main cause of failure for both handlebars and stems.

Realizing the importance of proper installation to get the most out of a precision stem, we made it as easy as possible to nail the torque values with a no gap design on our faceplate. It makes getting even clamping force distribution a cinch, so you can keep your focus on pointing the bars in the right direction.
