Challenge Grifo Team Edition Handmade Tubeless-Ready HTLR Cyclocross Tire

The new Challenge Grifo Team Edition HTLR (handmade tubeless ready) will be the envy of your local cyclocross race series thanks to their distinctive, unmistakable red sidewalls. This is a high-end, supple tubeless-ready tire for enthusiast cyclocross riders who want an all-conditions tire for racing.

Classic Grifo tread pattern, with new 320 TPI casing

This tire mates the proven Grifo tread pattern you already know and love to a new corespun cotton casing. Featuring a high thread count 320 TPI, it's Challenge's most supple and low rolling resistance tubeless tire for cyclocross.

To protect the new handmade cotton casing, Challenge has applied a special bead-to-bead waterproof coating - helping to extend tire life and appearance, even on bikes that are frequently pressure washed in difficult conditions.

Meets cyclocross tire width rules

As with the other Challenge HTLR cyclocross tires, the new Grifo Team Edition is designed to meet the UCI and USAC tire width rules (maximum 33mm wide tires) when used with rims with internal width of up to 23mm.

Inspired by Challenge Team Edition Tubular Tires

Prior to the release of this tire, Challenge Team Edition features have been limited to tubular (sew-up) tires. But with the release of this new line of Team Edition HTLR (handmade, tubeless-ready) Challenge has delivered Team Edition specs to riders who want to ride tubeless wheels and tires.

This tire also uses red sidewalls, available to the general public for the first time (previously, red sidewalls were only available on "sponsored athlete only" tires given to elite teams and athletes.)

PPS Puncture Protection Strip

No one wants a race-ending flat tire. The HTLR line, including the Grifo Team, utilizes Challenge PPS - a special fabric placed in between the tire casing and tread that reduces the risk of a race-ending puncture. 

S "Soft" Tread

For extra grip and performance the Grifo Team Edition HTLR uses a softer rubber durometer compared to traditional tires.

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.
