Brand new Challenge Strada Bianca Seta Extra handmade silk tubular tyre.

It is for standard 28" tubular road wheels and is the 30mm wide version.

The Challenge Strada Bianca Seta Extra is among the most exclusive tubulars in the world. The useage of silk thread makes it possible to produce a tyre with 1000 TPI casing. That is 3 times as many as top-of-the-line nylon casings, and gives a tyre which is superior in both handling and durability. They are so good that some pro teams choose to buy them and use for a few very demanding events instead of their sponsored tyres.
Here at ProOwned, we were fortunate enough to get our hands on a limited amount of these tubulars, which we offer for sale at a great price.

We will always advice our customers to ride in tight clothes. You can read more in the other tab “It has to sit tight”.

It has to sit tight

If you ever are in doubt about how tight a cycling jersey or your bib-shorts are supposed to be on you – there are some things to be aware of. The tighter the better – a good example of why this is important could be the bib-shorts. If you go for a longer ride and your shorts is not tight, you might end up with with pain in your bum – You always want to make sure, that everything is “in place” and does not move while riding this is something you can insure by using bib-shorts sitting tight on you, you will properly get a more comfortable ride.

Another thing to be aware of is that when you use cycling clothes sitting tight on you will break the wind better, which will result in better aerodynamic.
