Continental GP ? For Premier Bike wheels?

which tires fastest with good puncture resistance?

For racing fairly good roads. Almost all flat no hills. Very few corners.

Disc brakes

45 front
Disc wheel

I’m thinking tubeless Continental 5000 25 front 28 rear?

Is there a better tire or size to consider which would be faster but also good puncture resistance?

I went with the Vitoria Corsa Pro in 26mm for my Premier rear rim disc, and I dig it. Tubeless. Would go 28 if it fit my 2013 P5.

Dan told me the wheels were optimized for 25s.
