The good thing is that the Veloflex tires are available at a pretty neat discount, so it's relatively low risk to pick up a pair and try out. Will order one as soon as i wear through the current tires on my Venge.
couple of pics,
New veloflex on the right, old one on the right. Both 25mm.
New one, 212g. Old 207g. These are regular clincher. The new tubeless clincher is 21g heavier than the new clincher (not 30g like I said earlier).
The inner side look and feel very much the same,
Here are some obsrvations. The new one is a tad thicker in the middle, where the meat of tire is (probably good for wear). The bead of the new one is slighter tougher (Veloflex said for compatiblity of all carbon rims, no exception like Enve). The tubeless version just feels a tad thicker and heavier.
Veloflex claims that the new clincher has a lower rolling reistance, right. If you just compare the tread pattern alone, you (well, I) notice that the new thread pattern is not as aggressive as the old one (you can feel this by running your fingers up and down the thread), makes me wonder if rolling resistance is mainly due to changing tread pattern, but hopefully this won't compromise the new one's handling? we'll see
