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.

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.
