The 29*2.3 tyre which was meant to be 640g was 730g. They are lying about the weights. I weighed the tyre on a balance in a UKAs accredited lab so the 730g is accurate. Maybe once all the rubber has worn off it'll be 640?

I'm solely a cross country rider. I bought an Epic with these on the front and a Renegade on the back. As a front tire I would have given it 3 or 4 stars...it was better than expected given the low profile knobs, but not as solid in the corners as I would like. But I moved it to the back and have loved it. Super fast with good grip even in the loose-over-hardpack trails that I often ride. But I ride mostly dry trails. I've had 2 Fast Traks...this S-works series on the 29er and formerly ran a Control series on the rear of a 26er. I've never had a flat running these tubeless, but I'm not a heavy person. This is my preferred rear tire for cross country riding.

400km with those tires on my new Epic HT 2017 and 3 flats already despite riding tubeless. Two of these happened on a short rocky section. This tyre fails once it gets a little bit rocky. I am now looking for another brand to have something more reliable for racing

I won my class in first race on my new Epic, but the rear tire was almost flat at the end. Pin hole leaks in just 50 miles of riding that wont seal. But since I did well I bought two more of these tires on sale from this website. They also developed pinhole leaks that a double dose of Stans cannot seal. So 250 miles on my 2108 Epic, I have had three of these tires fail. I guess I will put tubes in them on commuter bike. Maxxis from now on.

Quando comprei a Chisel e veio equipada com este pneu na medida 2.3 achei que iria ficar pesado mas tem excelente rolagem e grip. E o que mais me deixou impressionado foi a resistencia a furos e rasgos. Pneu top, recomendado.

The 29x2.3 Fast Traks roll fast, corner well and have much more grip than you would expect. Seems true to size, nice volume. Lovely handling tire, quality is apparent. It also sealed up tubeless easily. However, I knocked off a star because weight is listed as 640g, mine weighed 700g. I look forward to trying other Specialized tires.
