Hi guys,

Its come down to a choice between these 2.

Going to put them on a SRAM S80 which is a pretty narrow wheel.

Has anybody found either of these 2 tired to be bad?


I'll be riding them for training and racing Oly to Ironman. So I do want some puncture resistance too built into the tires.

I don't see a 700x20 in the GP4000s (Black Chilli) will be using that tire in 700x23 in my rear Hed disc.

Many Thanks for your feedback.
