I've been using Specialized Mondo at 120psi for about 10 months on my Allez. Since it was my first road tire for many years, I had nothing to compare them to, so on that basis, I thought they were pretty good and certainly appeared pretty sticky. I went thru 3 tires in those 10 months (2 rear, 1 front) but I believe on one of the tires sold to me may have been 'funky'. I found them easy to install (using combination of Specialized and Rubino tubes) on 700x23 wheels. They seemed to ride smooth enough.

Then I came across the Krylions (at 116psi). On first acquantance, I thought it's just my imagination that the tires gave a smoother ride, but after a few more longer rides, I'm pretty sure the Krylions give a moother ride and certainly grip atleasts as well (probably slightly more because I've touched the pedals to the road on several turns, but that could just be a confidence thing as I gain more experience tackling corners). I went for the red striped tires which compliments my silver bike nicely, with red 'Allez' lettering.

So, Mondos good though seem to wear a little quick perhaps 1000 miles, the Krylions are nicer to ride on.

Edited: @StanSteven - by 'funky' I mean the LBS I got it from is not too poular with the local cyclists. After installing the tire I got a few flats pretty quick even though I checked the tube and tire before fitting; so I think a suspect tire was sold to me.

Edited: @SirReal - I'm a heavier rider so may be that's why I got 1000miles. Also, it's an approximate 1000 miles - I have no cyclocomputer installed. I've fitted 3 sets of Mondos and have got about 1000 miles per set.
