Silca launches bigger seat roll and latex tubes

Silca’s Seat Roll Grande Americano, a larger version of its Seat Roll Premio, has the ability to carry a 700x62mm (29×2.5) tubes or two inner tubes up to 700x30mm. Three internal pockets keep things organized. The roll is made out of water-repellent 1000D ballistic nylon, and the BOA Closure System snugs up tightly around seat rails to keep the roll compact. The Grande Americano costs $58. Silca has also collaborated with tire manufacturer Vittoria to create a latex inner tube. Latex is more elastic, so as the material is stretched or flexed, it returns to shape much faster and with less energy loss. Silca believes this results in a savings of up to 5 Watts. The latex tube weighs 85 grams and costs $15.


State Bicycle Co. grows its line

State Bicycle Company has expanded its popular Core-Line of bikes. The Ghoul, Ashford, Hunter, and Pigeon are built around a steel frame, which comes in three sizes (50cm, 54cm, and 58cm). 40-millimeter deep v-style wheels are equipped with a flip-flop hub so you can change from fixed gear to singlespeed. The riser bars are outfitted with Vans grips. Each model includes front and rear brakes and platform pedals. The bikes cost $299 each.


Become a virtual national champion with Zwift

On February 24, Zwift is hosting a virtual national championship race in 15 countries with the most registered Swift users. There will be a men’s and women’s race, and Zwifters should only join their country’s race on the day of competition. Rider’s will compete over the Watopia Volcano Climb course, which is 14.2 miles and climbs 669 feet per lap. The men’s race will be three laps and the women’s race will be two laps. Riders are required to wear a heart rate monitor to be eligible for the win and riders producing over a 5 watts per kilo average for the race will be automatically disqualified. These riders can be reinstated after providing similar real-life matching performances verified by ZADA. Furthermore, Strava data for the Zwift national championship races must also be open and not private or hidden. Riders can register here before the race.
