What Our Gearhead(R) Experts Are Saying:"I spec the PRO Vibe Sprint Stem on criterium and race builds where front-end stiffness and steering precision are the absolute priorities. The UD carbon construction delivers a rigidity that you feel immediately on the first hard out-of-saddle effort, and the fact that it rides with a surprisingly damped quality means you are not giving up comfort to get that level of stiffness. The alloy faceplate adds durability at the handlebar interface without compromising the overall weight."In a criterium, the difference between the front of the pack and the back of it often comes down to how precisely and confidently you can steer through a tight corner at speed. The PRO Vibe Sprint Stem was built for exactly that environment, engineered to be the stiffest stem available and designed to translate every input from your hands to your front wheel without a trace of flex getting in the way. The UD carbon body keeps weight at 206 grams while delivering a rigidity that PRO's own engineers describe as the ultimate in flex-free performance. What makes it genuinely impressive is that the stiffness comes without the harsh ride quality you might expect, the carbon construction provides a naturally damped feel that keeps the front end composed over rough road surfaces and through the repeated impacts of aggressive criterium racing. An alloy faceplate adds durability at the handlebar interface, and a proprietary top cap is included to complete the installation cleanly.
