Getting Rolling: Clement MSO 36mm Tubeless Tires

<Back to News Home |

EDITOR’S NOTE: We have come to the understanding that some readers think this tire is available now.  UPDATE: 12/15/15: We just got word that the Clement MSO 36 tubeless tires are being produced this month with initial shipments due to be sent out late in January/early February. We were promised more updates as the delivery time draws nearer. Stay tuned……

Tubeless tire

The Clement 36mm MSO on a Velocity A-23 rim

Getting Rolling: Clement MSO 36mm Tubeless Tire- The MSO tire from Clement was originally sold in two sizes- a 40mm and a 32mm size more suited to cyclo-cross. Now we have a “tweener” sized MSO in this 36mm tire, but it is much more than just a new size. It is tubeless ready. You can see our initial report on this tire here. Now it is time to get this review rolling, and here is how things have gone so far…..

 The MSO is immediately familiar to those who have been around gravel riding for a while. The small, neatly arranged center and mid-casing knobs are interspersed with some larger, more laterally oriented side knobs. MSO casings tend to be round with a low “C” shape profile when inflated and this tubeless MSO is no different in that regard. However; let’s stop here and take a look at what it takes to get the MSO set up and then I’ll move on to some first impressions of these new tires.

I immediately went to a set of Velocity A-23 wheels I have here for the set up to tubeless with these MSO tires. Velocity rims have a good track record with me and tubeless set ups with various tires, so I feel that the A-23’s will be a good base for this test. Those rims are typically built into a lighter weight wheel set, and the MSO 36mm tires are certainly directed at those who race gravel.

The A-23’s were wrapped in two courses of Velocity “Velotape” and I used older style Velocity tubeless valve stems. The sealant used was the Caffe Latex which we introduced in this post. One thing, as a quick tip, that I would recommend on any gravel tubeless tire set up would be to use a soapy water solution and brush that on the beads of the tires before mounting them. This will aid in seating the beads of the tires properly and also helps seal off the beads to the rims while airing up a tire for the first time. Using this technique, I was able to easily set the MSO 36mm tires up tubeless with an ancient floor pump. The MSO tires seem to be well suited to the Velocity rim profile so I would expect that these MSO 36’s should work on any appropriate width Velocity rim here.

Gravel tires

The MSO 36mm tires felt fast and comfortable.

Ride Impressions: The air pressures I first tried were okay, but at 43psi rear/40psi front, I could see I had a bit excessive “tire drop”, (think in terms of suspension sag), so I bumped up the pressures to about 48psi rear/42psi front and that was a lot better. Even so, at both settings I did not feel any excessive rolling resistance at all. I’ll be experimenting with air pressures as the review goes on, but so far I would say these should have a lot better ability to go to lower pressures with a good feel than the tubed MSO tires do.

Beyond the air pressures, the ride was smooth, damped, and much like I would expect from an MSO. Perhaps there is a bit more grip here in corners. The tire without a tube in there seems to conform to the irregular terrain much better. I’ll be searching this out for later updates on this review. The paved sections were fast, as I expected, and I haven’t found any coarse gravel with these tires yet, but I will………

So Far…..The new MSO 36mm tires are familiar in appearance and in much of their ride feel as well. However; that tubeless thing gives these an edge so far in the performance category over a tubed MSO. Easy tubeless set up on Velocity rims is a good sign for these tires.

Note: Clement Pneumatics sent over these MSO 36 mm tires to RidingGravel.com at no charge for test and review. We are not being bribed nor paid for this review and we will strive to give our honest thoughts and opinions throughout

    Have you tried mounting these tubeless on HED Belgium+ rims? I have a set of Belgium+ and I like the Clement tires that I’ve used so far.

    • Guitar Ted November 30, 2015 at 6:33 pm #

      That will happen after these have been used a bit on the A-23’s. This review will likely take about two to three months over which time I hope to try these out on a few different rims. Thanks for checking in!

    I ride the 40s tubeless – mostly asphalt at 30ish front, high 30s rear; mostly gravel 25 front 32 rear. I’m about 150. No problems in hundreds of miles except for a couple times i tried to go over 50lbs and blew off the tire (quite a mess). Still running that tire trouble free. I’m a risk taker, what can I say.

    Update: I mounted these tires on my set of HED Ardennes+, (same rim as Belgium +) with ease. They work well on Velocity and HED rims so far…..

    Has Clement announced when these might hit the shelves?

    • Guitar Ted December 14, 2015 at 3:09 pm #

      Michael- As per our note at the top of the article, all we know is that by Spring sometime you should be able to get these. We will update that when we get further info.

      Clement wrote to me today that the tires would be available “around the first week of January”. But then the last time I asked about tubeless tire release, the same person told me that the tubeless MXP would be available end of July 2015. Ergo grain of salt.

    Ted – what are your thoughts on the MSO 36mm tubeless vs the Specialized Trigger Pro 38mm tubeless? The Trigger Pros were flawless for me last year at DK200 and various other races but can be hard to get at times.

    • Guitar Ted February 1, 2016 at 7:51 pm #

      Steve, the Specialized Trigger Pros I tried were the S Works version, which were VERY thin and VERY supple. Nice, but they had no real lateral traction. I could break them free in corners and drift at will. Kind of sketchy that way. Otherwise they were super smooth and fast.

      The Clements are a tiny bit stiffer, a tiny bit slower, but have better lateral stability, and they seem a bit more robust in nature. Obviously, they are a bit heavier as well.

        Ted,
        Can you tell the width of 36mm MSO mounted on the Belgium+ rims?

    Any problems with wobble? I have a tire I just got and it has a bad wobble

    • Guitar Ted April 10, 2016 at 1:48 pm #

      Of the three sets I’ve seen, none had any wobble. You might try seeing if you could get yours replaced.

    • Ryan July 12, 2016 at 9:43 pm #

      Did you get this resolved? I just installed 2 on brand new grail rims and both have a serious wobble. Beads seem to be seated fine.

    What is the best suited tubeless tire you’ve come across talking speed on both tarmac and gravel?
    Best so far that i’ve tested is Hutchinson Black Mamba CX which i find faster than Schwalve G-One (35mm version).

    • Guitar Ted May 10, 2016 at 10:36 pm #

      That all depends upon what you have for gravel. Both tires you have mentioned would not be best on gravel here. It also depends upon you, your riding style, and your expectations.

      That said, I have liked the Clement MSO 36’s best for all around performance so far in a tubeless tire.

Trackbacks/Pingbacks

  1. Maxxis Rambler 40mm Tires: Getting Rolling | - December 10, 2015

    […] This may get modified as time goes on, because of my recent experiences with the Teravail Cannonball 38’s, (review here), which was a very stiff, unforgiving tire. The Rambler seems, at least for now, to be at the opposite end of the spectrum here in terms of ride feel. Damped, smooth, and fast are my initial impressions. I might add “fragile” to that list as well, as I had a freakish pinhole puncture on my third ride on these tires that the sealant didn’t seal, (sealant’s fault, not the tire), so I’ll also be keeping an eye on that as well. Oh, and by the way, the Rambler measures out to a 38mm on my A-23 rims, so that is a bit less than claimed. In fact, this tire looks about the same in volume as the Clement 36mm tire we also have on test here. […]
