I am looking for longevity reports and tubeless compatibility for this tire. Currently I am using my 29er hardtail as a gravel grinder machine and have a set of Geax Evolution's. The Geax tires have proved very durable with over 1,400 gravel miles on them with no signs of giving up, but I could not get them to seal up tubeless from the beginning. My biggest concern for the Clement is durability, as the Geax is one tough tire and has the weight to back it up in the 800 gram range. The Clement is listed as being in the lower 400 gram range, and may be more delicate, so I just need a little coaxing.
