Description: The Quantum Pro is engineered for the professional racer, and is probably the lightest road bike fuselage available. It offers an incredible level of performance, with frame rigidity and drivetrain efficiency that will satisfy even the biggest and most powerful riders. Offering an incredibly silky ride, this bike accelerates, climbs and handles like no other bike in the world.
We would say that this is a great frame for Road Racing and general riding, which is the design purpose of the bike, and which Klein's quality is exceptional. However, as a Duathlon/time trial set up, it's not appropriate.
That's because not one part is giving the rider an aerodynamic advantage, which is essential in a non drafting event where the riders race for the fastest performance.
I raced one of the first edition Quantum Pros for two years. That model had an integrated seat post tightener, which I cracked probably due to too much tightening. Klein sent me a complete new setup--frame, fork, stem--and even paid the shipping. Klein has since gone to a collar seat post tightener. Like the first frame, the new one corners like a razor and climbs like a turbo charged mountain goat. How they get the bike so stiff, yet so smooth is a marvel.
super light. excellent cornering. excellent climber. beautiful paint. its a stiff yet smooth ride. super fast. Highly recommended. I've owned two consecutive q-pro's...
Light as a feather, responsive, great ride Has that intangible special feel that you don't get riding other bikes. People still turn heads and look at the bike as I ride by them.
