Description

Tackle any terrain.

The Donnelly X'Plor MSO is a versatile tire is named in honor of the Missoula, Montana airport code, the home of the Adventure Cycling Association. Previously known as Clement, Donnelly tires feature a new name but the same great performance. It's designed for on or off-road adventures with an understated center tread rolls quickly on pavement while increasing traction on dirt and gravel roads. Chunky side knobs have been lifted from the PDX cross tire to bite down in loose conditions and inspire confidence in the corners. The result is a tire that's ready for virtually any riding conditions you might encounter.

This version of the Donelly X'Plor MSO features a 60 TPI Tubeless Ready casing and dual compound tread. 35-55 PSI recommended. Folding bead. 700c x 36, 700x40 and 700 x 50mm (36/40/50-622 ISO).

I'm a big fan of this excellent tire but they are very hard to find. They work well on gravel and pavement and are durable lasting 1500-1800 miles. When I got one with a factory defect they were quick to replace it at no cost. I will continue to use them as long as I find them.

Tire Review for WBW

I've used at least 5-6 of these tires and have found them to work very well on pavement and gravel. They have a small problem with sitting on my rims but with Stans seal it that seems to be able to be worked out. I would buy these tires again and recommended them.

Smooth Rugged And Durable

I got a good year out of the older iteration of this tire (branded Clement) on the front, so I figured I'd stick with the program.

Installation was a bear on my DT Swiss rims, but aging tape may have contributed to that. Once that got dealt with, the tires rolled true & smooth. I did a month of training then the Cycle Oregon 5-day rally (with some gravel options) without issue.

The front picked up a couple of tacks one day. The Stan's No-Tubes sealant did its job and the tire still holds pressure good as new.

The knobs wear down pretty quickly in the center on the rear. They're still sort of there after 500 miles, but it might be best to think of this as being a semi-slick type for the later half of the tire's life.

I will probably go back to a slick center design in the future, since that suits my needs just fine & wears down less conspicuously.

If subtle knobs are what you are wanting, I have no complaints or regrets with this model.

I currently have over 2,000 miles on a set of MSO 700x40 TR, and I am very pleased with their performance - as in NO PUNCTURES!! I run them tubeless on a set of HED Belgium. I ran them in the Almanzo 100, DK 200, Heck of the North and lots and lots of gravel training miles (note I have a 2nd wheelset with 700x30 road tires for non-gravel riding). I have no idea how they perform speed-wise compared to other tires, but they seem fast enough for me. And the fact that they havent flated in a race makes them faster than having to stop and fix a flat.

I will definitely be putting a new pair of Donnellys on my bike for 2019 - most likely another set of MSOs.

Good grip in the 700x36

I just built up a new gravel bike, but to save some $ I kept my road wheels...so I'm a little limited when it comes to going too wide, as I want to avoid any issues with my rims.

That said, though, I'm a huge fan of these tires. The 36 is, I guess, considered a narrow tire in the world of gravel, but it gives me a level of confidence that brings my off road riding to a whole new level.

On top of that, these tires are barely noticeable on pavement, which is an excellent thing.

Highly recommended.

Excellent tire. Rode it for SBT Grvl race and have gone through several as general gravel use tires. Have ridden the 40c and 36c versions of this. San Diego has tough rocky trails and need something that won't gash side walls if you ride hard. A slightly heavier than average tire because the sidewalls are so strong but result is no cuts. I passed tons of guys with flats on the sharp stuff on races. Great traction and fast on road. IMO 700x40c is the perfect gravel tire to go anywhere and Donnelly's are not going to leave you stranded.

Got the MSO 40s in 700c, tubeless. Mounting was not overly difficult. One of my pair inflated directly from a floor pump, the other required the compressor. Sealed (orange) fine. So mounting experience was very good (DT Swiss aluminum hoops). Rode a couple fondos (and other rides) and they took the abuse well. The Fondo was especially abusive with lots of sharp basalt rock and steep climbs. I picked these specifically because of the anticipated conditions for the Fondo and I am impressed. They have pretty good traction as well and the center bar rolls pretty well on the pavement.

Just finished a 200 mile bike tour in the hot and somewhat smoky Palouse in southeast Washington. These tires roll fast on packed gravel but a bit sketchy on the loose stuff. I'm very impressed on how well they roll. There pricey but I think you get what you pay for.

I have these on DT Swiss rims on a Lynskey Backroad frame used for commuting and touring. I like the feel and performance of the tires but with about 2000 miles on them the rear tire is already worn slick in the middle. For that reason I feel they are overpriced.

Used these tires (700x50c) on my Specialized Elite gravel bike and rode the the first phase of the Great Divide Ride from Banff, AB to Whitefish, Montana. Had about 45 lbs. of gear on bike (self supported). While I could have used a wider tire to handle the fast descents, these tires nevertheless performed exceptionally well. Never had a flat either-)

Without the gear on the bike I could have ridden almost as fast as on my mountain bike. Recommend these tires!!

Ran them tubeless with 35 psi at this year's Lost & Found gravel grinder. They provided reliable handling in the rough stuff, and were smooth on the pavement sections. No problems through a bunch of rocky sections where others suffered flats. I was very pleased.

I've run other brands, but these feel more secure in dirt and loose gravel. I have dropped back down to 36mm now, and find even with that smaller tire I have better control on soft surfaces.
