I have a set of Diamantes on one of my bikes and have more than 2K on them. They're decesent tires that handle well and have been totally puncture free. They are supple and comfortable. If you like a hard feel from your tires, these are not the ones, but that is a preference issue. I really like the tread, but it did not take long before the rear developed a flat center. In my opinion they don't seem to be fast rolling tires, but they don't feel slow or sluggish either...I'd say they get the job done. As for wet weather handling, I think you can do better. There strengths are suppleness, toughness combined with relatively light weight, and dry weather cornering. I was/am satisfied and would not hesitate to buy again if I was looking for a racey training tire.

Pros: Lightweight, supple, puncture resistance

Cons: Center tread develops flat spot quickly.

Great all around tire for poor road surfaces, but light enough for racing. Only complaint is the "crowning", that is, the flattening of the rounded profile after about 500 miles. You can rotate your tires, but a flattened tire put on the front is more noticeable when turning. I prefer to simply run this tire on the front where it lasts 3x longer or more anyway.

Pros: Price, performance, value, flat resistance

Cons: Crowning

I really like the ride of these tyres. Very confident feeling on high speeds and turns as you can feel the road and grip. Used Rubino before and these Diamantes have lower rolling resistance and faster. Durability really depends on road condition and some rural roads in Malaysia are just terrible, with lots of debris, bumps and pot holes. Hence my back tyre had a bad cut after about 1500 km. I didn't think twice to replace with same diamantes. I believe tyre punctures has got a lot to do with what tubes you use. Too thin a tube punctures are more common. I use slightly thicker tubes to prevent punctures. My wife's bike are on new Conti gatorskin and feels less grippy as they are mostly slick.

Pros: Nice grip and feel. Fast rolling

Cons: None

These are good tires for the price. They are on the light and fragile end of the spectrum but give reasonable wear. Pump up nice and round and have good wet and dry grip. A high performance racing or training tire. Would not recommend for commuting, etc.

I have been riding race bikes for 30 years and have ridden almost every major tire brand. Others say these tires get lots of flats, but where I ride the problem is they do not sweep the streets anymore, not the tire! These tires get no more flats than any other. And I find they last me 3-5000 miles which is very good. The best part is their ride. Compared to every other brand I have ridden these tires have a ride that is the best. They feel the road yet absorb the bumps, and when I am cutting corners at high speeds in the mountains they feel and grip like no other. One of my friends that rides both clinchers and sew-ups says these tires are as close to a sew-up you can get. The bike stores where I live are always sold out too, which is why I am getting one from Excel! For the price they cant be beat.

Used the Diamante Pro for the last year logging about 2500 miles. About 15% on dirt/gravel. In the past I’ve always ridden Conti’s (the 4000 and the GP) and noticed immediately that Diamante’s were a faster tire. Pretty easy to notice because when I leave for a ride I always have about a 400 ft descent over the first mile. These tires wore well and I only had two flats after the tread was pretty well worn. Personally I also found the tires to be a more comfortable tire than the Conti’s . My only caution about the tire is that as it wears, the center of the tire flattens out considerably (relative to Conti’s) and as a consequence I began to feel a noticeable difference in initiating a turn, it felt a little weird as the tire would transition from the flat center to the edge. In summary: great road feel, fast durable, great cornering when new, less so after about 1500 miles and I will buy another pair to replace the current tires on my bike.

I have used these tires for the last couple of years. Not very good tread wear and I have had too many flats. I would not recommend.

Very good puncture resistance and comfort. After trying many different brands, Vittoria is my preferred choice.

Excellent ride feel and grip. So-so puncture protection (Vittoria product with PRB might be tougher). Wear is not so good, I go through a rear tire in maybe 500 miles (I could go longer, but I don’t skimp on this). These are great tires... but something like a Rubino Pro is a better product for all-around street use.

I’ve used these tires for 2 seasons now. Excellent feel, grip, and endurance. Don’t know what the guy who got lots of flats rides on, but I’ve had mine in all sorts of conditions and seasons - even on gravel with virtually no problems.

I have over 1100 miles on mine and have only had one puncture, and I ride on a trail with lots of broken glass. Lots of little cuts show the effect of the glass, but only one puncture.

I have used these for many thousand miles over the past year. They have a nice road feel but by my experience puncture way too much - I finally switched as I tired of all the tube changes. I wouldn’t recommend to anyone as there are better products now.

An excellent tire with confidence inspiring grip. It’s relatively light with good feedback and ride qualities. I have put about 1,000 miles on them with 0 punctures and just a few cuts front and rear. The only down side is that these tires are much more dependent on tire pressure to avoid pinch flatting on road debris because of the the supple casing. I’ve ridden tires from just about every tire company and I’d have to (at least for me) rate these among the best.

Amazing tire with very low rolling resistance. Holds up well. No flats in over 1,800 miles. You will notice the difference when you ride these tires. GREAT VALUE!!!
