Challenge Grifo Pro Handmade Tubeless-Ready Pro HTLR Cyclocross Tire

Classic Grifo tread from Challenge on a brand new, handmade, tubeless-ready (HTLR) casing, designed to be a high-end, top performing cyclocross race tire for riders who prefer a tubeless setup. Designed to meet the UCI and USAC tire width rules (maximum 33mm wide) when used with rims with internal width of up to 23mm. 

All-around, all-conditions use tread

The Grifo Pro HTLR is ideal for riders who only have a single race wheelset, because the all-conditions tread works in wet or dry, rocks, roots, and grass. If you have to pick one single tire to run all season, Grifo is it. The center section offers fast-rolling knobs that offer excellent traction for pedaling and braking.

PPS Puncture Protection Strip

No one wants a race-ending flat tire. The Grifo HTLR features a special fabric between the tire casing and tread, reducing the risk of punctures. 

High-end handmade tubeless casing

This version of the Grifo is for cyclocross racers who demand top performance, featuring the new Challenge handmade (HTLR) tubeless-ready casing. The handmade casing creates a tire with low rolling resistance and comfort possible.

A similar tire, the Grifo Vulcanized Tubeless-ready is also available for riders who prefer the same tread shape, but in a more economical casing option.

Meets ISO, ETRTO standards, plus hookless compatible

The HTLR line from Challenge meets the new ETRTO and ISO tubeless standards, and is also hookless compatible. 

Challenge tubeless-ready tires can be mounted with or without inner tubes. When used tubeless, a liquid tire sealant is needed (Challenge's own SMART tubeless sealant recommended, but others can be used as well.) Challenge tires should not be mounted on wheels that don't meet ISO or ETRTO standards.
