Clement Xplor MSO gravel road bike tires and LGG road tubular tires

Clement has a new X’Plor MSO (a reference to Missoula, MT and Missoula Bike Works, who acted as a sounding board on the design) in a 700x 32. It joins the 40 width for more race oriented cyclocross bikes that can’t fit the wider tire. That one comes in September and should retail around $50 to $70.

The $50 version will have a 60tpi casing with polyurethane protective belt under the tread. The $70 one will. 120tpi casing, dual compound rubber and bead-to-bead Kevlar belt. The former is better against punctures, the latter for abrasion and cuts.

Coming in a couple weeks is a new road tubular based on the Strada LGG. It’ll have a smoother center section but keep the chevron tread on the sides. Like their others, it’s a tubeless tubular, meaning the inner tube is vulcanized to the casing, for a one layer construction. The benefit is that it’s lighter than a handmade tire, and it’s airtight so it works better with sealant. The sidewall comes precoated, and they say it’ll last much longer than a handmade tire and roll smoother with straighter tread lines. There’s also no risk of delamination of the tread from the casing. The tire will be called LGG and retail for $129.99.


  1. I had the 40c 120 TPI version of these for dirty Kanza 200 this year. Clearance was minimal to say the least on my Chinese carbon disc CX bike but they made it through without issues. One tiny flat that quickly sealed up with sealant. Great tire.

  2. My cycling partners in crime and I have been using Clement X’Plor MSOs on all of our big dirt road rides this year. Like Collin, that included a trouble free Dirty Kanza on the 40C 120 TPI version, where the hovercraft like ride and sure-footed grip of the MSOs was put to the test in a myriad of conditions.

    More recently, I was able to use a pre-release pair of the 32C 120 TPI version (*), in the Green Mountain Double, as documented here:

    214 miles with 24,000′ of climbing over dirt roads and, err, “roads,” put them to a thorough test and they passed with flying colours. If you don’t have room for the 40Cs, the 32Cs are well worth checking out for mixed condition rides.
