Item # PRS002S


Sharing its name with a large swath of desolate land on Mars, PRO's Tharsis Trail Stem anticipates you'll be taking it into some pretty inhospitable terrain as it sits at the helm of your trail, XC, or maybe even all-mountain rig. As such, PRO doesn't mess around with construction, CNC-machining durable, lightweight 7075 aluminum to create a stem with a commendable strength-to-weight ratio for barreling over everything from otherworldly craters to line after line of unforgiving rock gardens. It locks onto your handlebars via four-bolt,31.8mm clamp, and wraps around the steerer tube for a smooth, clean junction. In addition to conjuring images of futuristic space craft, the clean lines and sharp angles, beef up the design to make it something you'll be able to depend on when you steer your bike into the unknown.
