Continental Ultra Sport 2 Folding Tyre Twinpack

Amazing, these Contis, while not as robust as the gatorskins or the grand prix, are a terrific value. Get them on sale and you’ll want 2 sets.

Fairly grippy rubber and acceptable durability. But from previous experience with 23mm width tires, not great in terms of puncture resistance. Hoping with the 25mm size, puncture resistance is better. Great price on the twinpack.

Great tyres for track train and club racing, wear well use them on concrete, sealed and board tracks.

Got these in 25c to upsize my wife's skinny old rubber. Great tyres for the money. I found them a very tight fit, made more annoying as I forgot to check the rotation direction on the first one so felt compelled to refit it, though I don't know if it really makes a difference.
My daughter has them in 28c to roadify her 'cross bike. Very pleased with them.

I replaced GPll 4000s for these, a third of the price with no real difference in performance. Great value for money.
