Walking around the 2022 USA Cyclocross Nationals expo, we noticed an exciting tire at the Challenge Tires booth. An updated Baby Limus is on the way, with a slightly tighter tread pattern and new side knobs.

What is it?

It’s no secret that Tom Pidcock is working with the design team at Challenge Tires to craft better cyclocross designs. One of the first updates from Pidcocks’ input is this newly imagined Baby Limus tread. The updated design takes the Baby Limus into faster “mixed terrain” territory without sacrificing grip.


What’s new?

The updated Baby Limus tread features a tightly spaced center to maximize rolling efficiency, it’s not certain, but the knobs look shorter (from the previous model).

The most notable change to the Baby Limus design is the side knob and shoulder tread. Departing from the Limus and Chicane treads, the updated design has characteristics of the Dugast Rhino, with less of a pronounced corning knob. The side knob is flipped and should offer a solid grip in off-camber sections.

One of the complaints with the previous Baby Limus design is clearing, especially in thick peanut butter mud. The new Baby Limus has ample room for mud clearing, and the updated side knob spacing helps.

Old Baby Limus
The current version of the Challenge Baby Limus is a fast-rolling tire, but the updated version appears to be more performance-focused.

When can I get it?

Currently, the Team Edition Baby Limus is only available to sponsored teams/athletes but were hopeful they will be available for the general public next season.

Am I completely mistaken, or is this not the identical tread to the Donnelly PDX?
It would make sense, as it is an awesome tire, but not popular in Europe.

My thoughts exactly….the new version looks amazingly similar to the PDX. I’m running the PDX WC and its a phenomenal tire that can handle mud OR general all-around conditions.

It’s very close, but some of the knobs are shaped or orientated a bit different.
