Torelli Extra-Lite ATB tubes were also cited by Mountain Bike Action as one of the ten hot things you should buy!
Torelli Extra-lite tubes are the most cost-effective way to improve the performance of a bicycle.
Torelli tubes enhance performance two ways. First, the rotating weight is substantially reduced. Given that the energy needed to accelerate the rotating mass of the wheels is greater than the energy needed to accelerate any other part of the bike, this weight saving is important.
The other energy savings is gained by flexing less inner tube mass. The tire and tube are deformed as they roll over the ground. This deformation takes energy. By reducing the thickness of the tube, the energy needed to roll the wheel over the ground is reduced. More of the rider's energy is used to propel the bike forward at a higher speed.
Torelli tubes are butyl rubber. Extensive investigation and tests convinced us that the reliability and repairability coupled with the low cost made butyl the only choice. We went to France for our tubes because the density of the butyl available there allowed us to make the tube only .4mm thick and have it still retain air.

Torelli "Torino" Open Tubular. The Torino Open Tubular tire is made with a 240 TPI casing that gives a superb road feel and unrivaled perfomance at this price. If you see one at a shop, take it in your hand and crush it. You will be surpised at how supple the casing is. This supple casing allows the tire to immediately adapt to changes in the road surface.
To eliminate friction and stress between the casing and the tread, the tread is hand-glued to the casing. This hand made process is called "cold treating". This is how the most expensive tires used by the most demanding professionals are made. The result is the equivalent of radial tires for your bike.
Suggested retail price: $34.95
Torelli Arezzo Open Tubular. Everything written above about the Torino is true about the Arezzo except more so. The Arezzo is a higher-performance tire made from a lighter, more flexible casing. The higher thread count tells a lot of the story.
Suggested retail price: $49.95
Torelli Pneu Grande Vitesse (PGV). Many riders prefer a traditional clincher with its thicker vulcanized tread. For those who find the need for durability very important we offer our PGV and TDF (below) tires. We have worked to make the casings supple for superior response to changes in the road surface. Our PGV is the state-of-the-art clincher using a 120 tpi woven nylon fabric casing and a natural rubber-butyl blended tread. The tread uses Torelli's grippy, soft formulation to give the bike maximum corning power. Tread pictured below.
Suggested Retail: $49.95
Torelli Tour de France (TDF). Looking for a good training tire with a supple casing and soft tread that wears well? Then the TDF is your tire. The TDF has a 60 TPI woven nylon casing and a sticky tread. Don't get training tires that beat you and your bike. We're supposed to be having fun. Tread pictured below.
Suggested Retail: $39.95

Torelli Lugano Tubular (Sew-up). The Lugano is made from a 320 tpi polyester casing sewn around a latex inner tube. Weighing 280 grams, it offers absolute top-of-the-line perfomance for the most demanding athlete. When you get one to mount you'll discover another advatange ot the Torelli Lugano: it's straight. If you have ever tried to glue a lumpy or crooked sew-up on to a rim you'll appreciate the care that goes into these fine, hand-made tires.
Suggested retail: $69.95
