Bontrager RSL Tire Line Offers Four Designs With World Cup Ambitions

Bontrager is ramping up its RSL (Race Shop Limited) line for 2024. Trek is bringing more gear under the once-limited RSL moniker. “RSL” is replacing the “XXX” line of top-end Bontrager and Trek goods. We’ve seen it recently with the newest Trek Road shoes, which makes sense. Now its the new Bontrager RSL mountain bike tires.

Another thing that makes perfect sense is the new naming convention of these Bontrager tires. The team traded in the “XR2… “etc. for actual names of the courses and locations that the tires succeed on. Even more remarkable, you can tell the course’s demands just by the tire’s tread. Now, in case you’re not watching every World Cup like it’s the Super Bowl (like some of us) let me catch you up on the newest cross-country and trail treads from Bontrager.

Bontrager RSL Cross Country Tires

Vallnord RSL

Vallnord Andorra is an iconic World Cup location known for fast, dry racing. The new Vallnord design effectively replaces the Bontrager XR1 but maintains many features.

Mont Sainte-Anne RSL

If you know World Cup XC, then this name is very familiar. Mont Sainte-Anne is a staple of the World Cup circuit. Where the sharp rocks and endless roots aren’t even the worst of it. Riders contend with super steep climbs, mossy rocks, and lots of natural water from the soil.

The Bontrager RSL Mont Sainte-Anne replaces the XR2 as a Bontrager all-around tread. The trend, however, sees many updates from the previous iteration. It is adding more horizontal knobs for wet weather traction that are thin to conform around wet roots and rocks.

The Mont Sainte-Anne RSL is nearly 40 grams lighter than its XR2 predecessor and offers nearly double the puncture resistance. All this with a boost in dry and wet corning grip.

The Mont Sainte-Anne will be available in both RSL and Pro casings. The RSL boasts a 220TPI casing, while the Pro has 60TPI. Both have reinforcing XR puncture protective casings and Bontrager dual compound center and shoulder.

Montrose RSL

The Montrose name comes from the land of ride-it-all single-track. It is a place where you can find fast trails and ones that require skill in cornering, braking, and courage.

The new Montrose RSL replaces the XR3 trail tire. Bontrager describes the Montrose as a “fast-rolling trail tire,” but it’s a do-it-all tire. The casing is a supple 120TPI with a triple trail compound: medium center, soft shoulder, and supportive base.

Compaired to the XR4 the new Montrose RSL has double the tread puncture protectivity, and a slight uptick in side wall puncture protection. The wet corning grip is nearly the same at the XR4 Team Issue, but with an increase in dry cornering grip thanks to new sculpted knobs.

The Montrose should be an excellent performer like the XR3 it replaced. , bridging the gap between aggressive cross-country riding and fast technical trails. Unlike the cross-countries above t, the Montrose gets the more robust puncture protection casing. , helping and off sidewall cuts and pinch flats.

Gunnison RSL / PRO

The Gunnison takes its name from the gateway to the most iconic rides. , with rails ranging from rocky desert terrain to high alpine classics. The design echoes that, with an aggressive design and options for riders looking for absolute performance and longer wear.

The Gunnison replaces Bontrager XR4 and SE4 tires, delivering an all-around trail tread that offers grip and speed in mixed conditions. The tire looses weight over, coming in about 55 grams lighter than the SE4 Team Issue. The newly tweaked design sees a increase in tread puncture resistance and a large up tick in wet corning traction.

For those looking for performance, the Gunnison RSL is 120tpi and the more robust Pro casing is 60tpi. The Gunnison is available in both XT and XR puncture protection offerings and a triple or dual tread compound.
