I can enjoy a good trip with this wake 45mm mountain bike stem. This mountain bike stem only weighs 130 grams and is easy to maneuver with a 31.8 handlebar and a 28.6 mm steerer diameter. This 6061 T6 Aluminum alloy bike stem is my fave. Such an alloy is known for its good formability and malleability. Everything about this bike stem is solid, snug, yet lightweight and versatile.
