Bontrager XR1 Tire

4/5 (14 Reviews)
MSRP : $47.00


Product Description

Designed in collaboration with Bontrager-sponsored pro race team riders, the XR1 is an ultra-fast rolling cross country race tire that's ideally suited for dry and dusty condition. Small, tightly spaced knobs provide plenty of fast-rolling traction, while siping (thin slits) across the middle knobs give even more grip on dusty surfaces. Designed for front or rear use.

Strengths:    2.4" is 560g
Fast rolling, outstanding resistant to pinch flats
Very well constructed


Weaknesses:    Wish the blocks on the edge was bigger for better cornering

Bottom Line:   
I commute on my hardtail bike to work. I also take to the road to ride up to Pompano Beach from Fort Lauderdale. I used to run 1.9" tires under the idea that narrower tires translated to lower rolling resistance. But three pinch flats later, and one dented rim, I decided to try the 2.4" after seeing them on a bike at my local bike shop.

The tires are the widest I have ever ridden. I feel like I am on the Batman Motorcycle when I ride. I run at higher pressures and these tires ride faster and much quieter than the Tomac's I previously ran. I feel less beat-up and have less fatigue on my hands and wrists.

The challenge was inflating these tires. I saw examples where people were able to fill tubeless tires with a floor pump. No such luck. These tires required compressed air. I used 2oz of Stan's on each tire and they sealed up easily without the need of soap and water.

Strengths:    Speed
Cornering traction
Pretty tough
Easy tubeless set up


Weaknesses:    mud

Bottom Line:   
I used the 1.9s on a hardtail set up rigid for a gravel road race. They set up tubeless very easily on ENVE rims. I am 145lb and ran 22/24 psi fr/rr. Probably could have gone lower, but I didn't have enough time on the tire to be comfortable with lower pressures. This tire is a great choice for gravel grinders, STXC, or dry XC courses. Very fast rolling and they surprised me with their cornering traction.

Strengths:    light weight, easy pedaling on pavement and dry trails

Weaknesses:    probably not the best in a lot of mud

Bottom Line:   
I really like these tires. Should probably give them five chilis... They are great here in the southeast. I tend to avoid mud and spend equal time on trails and pavement. I ride a Surly 1x1. Mine need replacing soon. Thinking of trying the Kenda Small Block 8, but may just buy another set of these.

Strengths:    Super fast!

Weaknesses:    Mud

Bottom Line:   
These tires have worn really well. They hold on loose corners and in the silt like dirt here in OR, while performing in the rocks. Worked well on a trip to Moab as well. The XR1 feels fast on steep climbs and flies on the decent. Not great in the mud yet are ok in the snow. I would buy them again!

Bottom Line:   
Awesome tire for the rear in totally dry conditions but just not versitile enough for Michigan riding. I swapped them out for the new Bontrager XR2 and I'm much happier.

Strengths:    Very fast, light, responsive, high-volume, and supple tire

Weaknesses:    Durability, price, steering control, mud

Bottom Line:   
These are FAAAAAST tires for pavement or hardpack conditions. These tires very closely resemble a low-profile version of Small Block 8's. In fact, I would call these a "Small Block 7" as they have 7 small knobs in each row of the tread. They are light, fast, supple, and responsive. I run the 2.2 and they have good air volume to run low pressures. They grip surprisingly well on the rear in dry conditions. They set up OK with Stan's, maybe taking a little sweet talking and definitely a compressor.

They don't like rocks or mud. I have about 15 rides on mine and they look like Swiss cheese. They simply can't hold up to everyday use on real mountain bike trails. Riding in mud is like riding on ice with these tires. There are also better front tires out there too. While the slide is predictable, the tread pattern is definitely not set-up for side-to-side traction. Watch out!

All-in-all, these are great tires for racing on smooth and dry courses, for pavement, or for really smooth trail riding. When you can keep air in them and ride in a relatively straight line, goodbye, they're fast as hell. Otherwise, flip a coin...I'd say it's a 50/50 shot you'll be tubing or walking to the car if you ride over any sort of fast rough stuff...

Date Reviewed: May 3, 2010

Strengths:    Very low rolling resistance, lightweight, fast acceleration, supple feel

Weaknesses:    Very little cornering grip

Bottom Line:   
The XR1 makes for a good rear tire, be careful when running it on the front. It will corner well on dry, dusty hardpack (not sandy) and tacky soil.

But when you venture on to sandy trails, loose trails, or wet trails, traction quickly goes downhill.

Break down of how the tires perform in dry, hardpack conditions or tacky soil.
Straight line - Outstanding
Accleration - Outstanding
Feel(suppleness) - Outstanding
Corning - Good
Braking - Great
Climbing Traction - Good
Wear - Great (700 miles of trail and road and they still look good)

Date Reviewed: May 1, 2010

Strengths:    Light, low resistance, great stick on dry roots and rocks

Weaknesses:    Not good for cornering in any conditions. Not great for braking. Also useless in wet and muddy conditions, but to be expected as any tire with low tread.

Bottom Line:   
The tire is surprisingly sticky and works great when climbing and driving through roots and rocks. It's also very light and has very low roll resistance. Unless you're only riding in a straight line though they do more harm than good. Even in the most ideal conditions they easily wash out with any aggressive cornering. Not very effective braking either causing you to slow too early. My low ratings are based on high speed trail use.

Strengths:    Very light, low rolling resistance, surprising traction

Rear tire only.


Weaknesses:    Wears out fairly quick. Mud. Do not use on front

Bottom Line:   
I was really happy with this tire. It hooks up really well and rolls like a road tire. It has zero nob roll and is very plush. I ran a 2.2 size with zero issues at lower pressure. The sidewalls are fine in sharp rocks.

I only replaced it as the trails got looser due to lack of rain.
I will throw it back on for monsoon season after the trails pack down a little. You loose a little traction on climbs if you saw at the pedals and dont keep weight on the rear tire. On buff packed trails it rails thru turns and really rolls nice. I haven't ridden a faster tire.

Not good in mud at all. 3 chillis for value as it does wear, but it still hooks up even worn, but you can tell its days are numbererd. 5 overall becouse it raises awareness about how little bigger knobs do for traction on buff trails.
