Update on the Corsa G+
2. Had a scary experience on the ride today. On about an 18% downhill where you need to brake hard into a curve, I locked up the rear wheel. I was braking with the same force I've used on the Comps and Carbons and neither would have locked up. My weight was same as always in such a situation, leaning rearward. This reminded me of the older Vittorias I tried where I experienced similar lock ups. On the Carbons or Arenbergs, if you lock a wheel, you lose a lot of rubber. Checked afterward, not so on the G+. Not sure I've locked the rear on the Comps.
Net: the G+ seem to have less dry traction, at least when braking in a straight line. I wonder if the compound on the edges is more supple / stickier for turns and the center harder for longevity? Anyone know? Wasn't super confidence inspiring!
I had exactly the same experience, steep technical turn into a switch back - smooth / dry surface. The back wheel slid out, whereas Veloflex hold. Hardly any rubber off the rear vittoria, whereas I would have expected to see rubber off Veloflex.
Summary, I think they are great for distance - but the trade off seems to be grip. I'm pulling them off and going back to veloflex.
The other observation, and I'm not sure if it's just me - but the groove along the side, seem to provide a weak channel for debris to go. Eg the extruded ridges are too hard to cut, so the articles move to the channels and maybe increase punctures. I'm not sure on that last point, maybe others have had different experiences.
For grip - Veloflex seems better IMHO
