CW tests the updated version of Continental's time trial-specific rubber
With three plies and a total 180tpi they are not, and do not feel, as supple as some of the tubs by Conti's Italian rivals, but the Germans no doubt have their own test results to prove their choices are the right ones, taking everything into account including price.
However, they are very well made, reassuringly tight on the rims and once in place, crucially run very straight.
I have been very impressed by the complete lack of cuts after two hilly time trials, both of which I rode out to. At half the price of a Veloflex Record, you can ride out on these, but you get what you pay for, and if you want super-supple silks you have to pay more, and risk puncturing more too
