LUNJE CNC Bike Stem 45mm Power Climbing Geometry
Precision CNC machining creates a climbing riser geometry that positions your body forward and upward for maximum mechanical advantage on steep grades and technical terrain. The high-strength aluminum alloy handles the impact forces common in downhill sections and rough trail conditions without creasing or permanent deformation. This MTB road bike stem’s 31.8-millimeter bridge accommodates modern handlebar diameters while the 45-millimeter vertical rise suits riders seeking aggressive hand positioning for attack descents. Independent testing confirms zero play or movement between handlebar and frame attachment points, delivering the steering precision demanded by experienced mountain cyclists. The LUNJE CNC design balances weight savings against durability, ensuring you get performance that lasts through entire seasons of demanding off-road riding.
