Challenge Baby Limus Pro 38mm HTLR Handmade Tubeless-ready Cyclocross Tire

The Baby Limus, one of my favorite tread patterns for cyclocross from Challenge, now comes in a brand new, 38mm wide version. 38mm wide tires for cyclocross offer more grip and handling in 'cross races where the 33mm tire width rules are not enforced. 

The Baby Limus 38mm uses the new HTLR (handmade, tubeless-ready) casing. This is a high-end option for cyclocross racers who prefer to race on tubeless instead of tubulars.

Bikerumor.com says: "If you’re riding a very bumpy course with lumpy grass sections, you’d love the 38mm suspension-like feel."

Baby Limus blends features from the Grifo, Limus, and Chicane

Start with the Limus, but shave down the tread so the knobs are shorter with less rolling resistance. Add the Y-shaped knobs from the Chicane for edge cornering and you've got a great jack-of-all-trades tire for cyclocross racing, and in the new 38mm version, and you've got a winner for bumpy, rocky, rooted race courses.

PPS Puncture Protection Strip

The Baby Limus 38mm HTLR features a special fabric between the tire casing and tread, reducing the risk of punctures and preventing race-ending flat tires.

Meets ISO, ETRTO standards, plus hookless compatible

The HTLR line from Challenge is hookless compatible and meets the new ETRTO and ISO tubeless standards.  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, or use popular sealants from Stan's NoTubes, Orange Seal and similar)

Don't mount Challenge tires on wheels/rims that don't meet ISO or ETRTO standards. 

• Folding Aramid bead
• Black tread with tan sidewalls for that classic "look"
• 300 TPI Superpoly casing

Maximum tire width rules in cyclocross races

Most Elite cyclocross races (think professional-level Superprestige, World Cup; and some National Championships) impose a tire width limit of 33mm, but most local race series held at the amateur level have no such limits, allowing riders to ride tires like the 38mm Baby Limus.
