I've currently got the Continental ultra sports, which tested decent on a rolling resistance test I saw the results for on another site. It's about time to get new tires and I'm looking for the fastest option in the 27 1 1/4 size. I haven't seen many options. Ond that I have seen is the continental grand race. They're higher priced but I think it's because of the added puncture protection. They look similar to the ultra sports and I'm not sure which one is faster.
So yes, any recommendations
