Open tubular differ from traditional clinchers for the construction. The Tyre is produced just like a tubular and uses the same materials and production process. Instead of being sewed with an inner tube inside, at the end of the process beads are made by folding the casing around Aramid fibers threads. For this reason an open tubular gives very similar ride feel of that of a tubular, mainly if a latex inner tube is used.
Mounting an open tubular on a wheel is the same as mounting a standard clincher but with the advantage of riding a much more comfortable and performing tyre.
These tyres are for racing style bikes that use clincher/hooked rims, these are the most common fitment and hook onto the rim and require an inner tube. There is a wide choice of tyres within this category and the right choice is important. Lighter tyres will accelerate quickly, but will be more prone to punctures so getting a balance is extremely important. If you require a tyre for all round use look for something with puncture protection, an average TPI(Threads Per Inch) and average weight. If you require a fast tyre and speed is the only thing that matters look for a low weight folding tyre with high TPI. If durability is your priority and speed is not so important look towards the puncture resistant tyres and consider going for a wider tyre, these will be less prone to punctures and offer a bit more comfort. For wet road conditions a triple compound or winter tyre is a good choice, these use a softer compound on the cornering surface to maximise grip.
