For those in a hurry Veloflex tires are great for those looking for a very smooth ride, high traction, reasonably low rolling resistance and a road feel that is more akin to a tubular tire. In particular, its the smooth feel, and the confidence I feel while cornering on them, that really stand out. They're also extremely quiet. I've ridden them on only a few short shake-down runs to check handlebar and brake lever positioning, so I'll update this later, after I check the tire's wear, traction and puncture resistance. But I can say without reservation that they are the most comfortable and confidence-inspiring clinchers Ive every ridden on, even in a 23 mm tire size that runs true to size.
A bit more detail They were difficult to mount (Veloflex cautions against using levers) on my old-school Mavic Open 4 CD rims (inside width of 13.2 mm). I didn't want the light-bulb effect and poor aerodynamics of combining a narrow rim with a wide tire, hence my choice of a 23-mm width. I used Schwalbe's high-pressure fabric rim tape, and Michelin's Airstop A1 butyl tubes. (Sorry, latex fans.) One of the tubes had a small leak in it after mounting - my fault, Im sure - and I used the Pedros to make safe removal easier. When I remounted the tire with a new tube, I used the Koolstop Tire Bead Jack, which I HIGHLY recommend for safely mounting hard-to-mount tires in seconds. I used 116 pounds in the rear, and 107 in the front, (using an Accu-Gage analog tire gauge).
So, how'd the Veloflex Corsa tires perform and feel on the short runs I took them on? They were superb! Id read that tires make a significant difference - possibly the biggest difference - in how a bike handles and feels, and I certainly believe that now. I would literally have noticed in a few yards - blind-folded. My bike, which has a frame of Tange OS 4130-tubing, now feels like a French-made Roold bike with tubular tires that I had many years ago.
I often tried to analyze why that Roold felt so good, and concluded it was due to its sew-up tires - there really is a difference. Thats what prompted me to try the Veloflex tires - reviews often mentioned that the feel was akin to tubulars. The reviewers were right! The Corsa tires make cycling more fun, and isnt that what its all about?
For someone who is looking to lower a PR by a tenth or two, or who cycles over broken glass and road construction, there might be somewhat better choices out there. But for enthusiast riders who cycle on decent roads for exercise, fitness and fun, and who value a soft, smooth ride, even at high pressures, the Veloflex Corsa is a superb choice. The $30ea sale price I got mine for from Bike Tire Direct made them a steal, but Id be willing to pay full price, if necessary.
Thank you for your feedback.
