Challenge Adds Two 700x30C Gravel Bike Tires
Challenge’s Almanzo and Eroica are two new 700x30c wide gravel road race tires.
Eroica is named after a race in Tuscany, Italy. It’s got a 260tpi casing and comes in at 340g for the tubular ($110) and 320g for the open clincher ($76). Available in black and skinwall.
Almanzo is named after a US gravel race and is a slightly narrower version of the Grifo XS. Same basic specs as the Eroica but with a more aggressive tread pattern.

Both have dual puncture protection using a new material, one layer directly under the tread and another (red) inside the casing. Available now.
Latex tubes now available outside of a tubular tire. They’re completely seamless. Road tube is 65g and cyclocross version (wider) is 75g. They launched this past season, but production wasn’t up to demand so they’re ramping up.
