Storage? I am Storage!
The tires started out about 2 mph slower than air tires. Within I'd say the first 100 miles this quickly improved to the point where they were only about 1-1.5 mph slower. Ever since it's getting slightly better, to the point where now I'd say the difference is practically unmeasureable ( 1/2 mph or less ). I'm basing my figures on typical average speeds I do on rides. Given that no two rides are the same, it's a difficult comparison. Nowadays when I have a good ride with relatively little need to slow or stop my average speeds tend to get close to 16 mph ( note that included in this average speed are ALL my stops or slowdowns-my cruising speeds typically range from 18 to 23 mph on level ground, depending upon weather and how I feel ). Anyway, this is roughly around where they were 3 years ago when I was riding the same amount using air tires. A few rides I got into the high 16s back then, so maybe air tires are still ~1/2 mph faster. Truth is unless someone keeps meticulous records like I do, they wouldn't even notice such a small difference.What changed? Were the tires slower before OR was it harder to stop? Softer or harder.
As for softer/harder, I'd say the tires got a little softer but also less stiff. Basically, that means a slight improvement in both ride quality and rolling resistance. As for traction, never a problem. I can stop or turn same as with air tires. I really think most of the reason airless tires are disliked is because of people not really giving them a chance. You really need to put a few thousand miles on the tires before they reach their ultimate potential. Incidentally, looking at the amount of wear after about 2200 miles, I think I can get an easy 10,000 miles out of these tires, perhaps even twice that. Considering that a set of regular tires lasts me 4000 miles at most, this is great news.
BTW, how did you fracture your ribs? Was it in a bike accident? It sounds really painful.
