I've ridden cheap tires and more expensive tires. As a general rule, I'm not wasting any more time or money on cheap tires. One of the few things that will quickly change your bike IMO. And a big reason why I'll avoid any 27in tire bikes going forward as the best option is a Pasela.
BTW Grady, offer still stands if you want to see if that Park Pre will clear RTP. I still want to see that bike anyway. Ha
