Specialized Pathfinder 29 x 2.2" tyres put to the test: Narrow XC tyre vs. wide gravel tyre

Professional riders wanted the new Specialized Pathfinder tyre to offer more volume, more traction and more speed. So the Californian brand gave their gravel tyre more air volume and increased its dimensions to 29 by 2.2 inches. Despite the extra material, the Pathfinder 2.2 is said not to have gained any weight. Specialized racing cyclists have already been using this new development in both gravel and cross-country races. But is this fast tyre also suitable for non-professionals? We put it to the test.

Conclusion

Having tested the new Specialized Pathfinder 2.2 on both a gravel bike and a mountain bike, I have to say: its practical range of use on a cross-country bike is as narrow as the tyre itself and limited to fast, dry sprint courses at best. The situation is different on a gravel bike. There, the combination of smooth rolling and shock absorption is impressive. However, other tyres offer even better grip. - Jan Timmermann, BIKE editor

Gravel tyres go cross-country

The Specialized Pathfinder was originally developed for gravel bikes. However, speeds in the Cross Country World Cup are now continuing to rise. In short-track races in particular, the pace is faster than ever, and manufacturers are increasingly on the lookout for small but decisive advantages. That is why more and more racing teams are testing high-volume gravel tyres on XC mountain bikes. As early as 2025 in Nové Město na Moravě, many World Cup athletes could be seen riding on narrow tyres with minimal tread. The aerodynamic advantages of a narrow tyre can be decisive at world-class level.

In a direct comparison with its predecessor, Specialized claims the Pathfinder 2.2 offers a 21-watt advantage at 30 km/h. The American manufacturer achieves this primarily through an optimised construction featuring a Gripton T2/T5 rubber compound and a modified carcass. According to Specialized, the larger tyre is said to offer better puncture resistance, meaning less material was required. Furthermore, the tyre construction is designed to use a harder rubber in the centre of the tread for faster rolling, and a softer rubber on the outer edges to improve cornering grip.

Our impressions of the new Pathfinder

Compared to the delicate titanium tubes of our test gravel bike, the new Specialized Pathfinder 29 x 2.2 looks like a balloon about to burst. The tyre is large and round. On most gravel bikes, this can still be a problem at the moment. Only a very small number of models are approved for 55-millimetre-wide tyres. However, the trend is clearly moving towards wide tyres. Even the new, weight-optimised Specialized Crux 5 Race gravel bike has been designed to accommodate 55-millimetre-wide tyres. Thanks to its large volume, the Pathfinder provides a smooth ride. Small pebbles are simply absorbed, and kerb edges are no longer a cause for concern. The chunky Specialized tyre is a real asset when it comes to riding comfort.

On tarmac, fine gravel and in dry conditions, the Pathfinder really comes into its own. Even on the road, the closed centre rib rolls along quickly and quietly. On easy terrain and in urban settings, it allows you to cover ground quickly. In corners, the softer sidewall rubber comes into its own. This means the tyre allows for more lean angle than you’d expect from its unassuming appearance – thumbs up! On wet surfaces or coarse gravel, the picture changes. Grip and traction are still decent, but can’t quite keep up with other gravel tyres in the 29 by 2.2 or 2.1-inch sizes. Whilst riding through the damp forest, we preferred to steer clear of mud and roots.

The Specialized leaves a similar impression on a mountain bike – where, visually speaking, it looks unusually narrow. For short-track races on dry days, the new Pathfinder is definitely worth a try. On the start-finish straight, for example, the fast tyre pulls you forward with noticeably little resistance. Here, the rider’s input is instantly converted into speed. When the course turns into the woods, caution is advised. Racers should choose their line carefully so as not to lose traction and grip. The Pathfinder 2.2 is clearly a specialist tyre – good for gaining that final bit of an edge in competition, but not without its compromises in everyday use.

Strengths and weaknesses

Pro

• fast and surprisingly grippy on firm, dry surfaces
• The large volume ensures comfort on a gravel bike
• Weight remains low

Cons

• A trade-off between traction and grip as soon as the surface becomes damp or loose
• a very specific area of use on mountain bikes
