Two parts to that statement. Price, and value.
Ultrasport ‘s are online for £12.99. GP4000S for £54.99 including 2 tubes. Those are the first proper few in comparison page called Bikesy. Thats less than two to one, not factoring the tubes in.
Value is harder to quantify. I had two punctures in less than 200 miles. 4,700 without any on the others. More importantly for me, the grip was my main motivator, or lack of. I like to corner and descend fast and I had a good number of occasions where the tyres didn’t cope and grip was minimal. For me, that was the deal breaker, value wise, with punctures as the clincher (no pun intended). I generally ride for pleasure, so a puncture is inconvenient, but for commuting it will matter a whole lot more.
The value element will vary for others, so my points may or may not matter, dependent on requirements. That’s where the perception of value comes in.
