Reviews
I wanted a tough tire that rolls fast, and has some grip for a few gravel races. Like the other review mentioned, these tires are not easy to get on the wheel. Because they are hand made, they are virtually flat when they arrive. I mean they are a ribbon of rubber with no shape. So you need to get one side on the rim, and it will start to take shape, then you will fight to get the other side on. There is no point in buying these tires unless you plan to go tubeless. Any attempt to change a tube, or add a tube on the side of the road would be fruitless. Thankfully, these are tough tires, and not likely to need any help one mounted and sealed. They were surprisingly easy to inflate and seat once they were on the wheel. I did lose air overnight initially, but then over inflated them again, and shock out the sealant, and they were just fine. These are fast rolling, tough and grippy. I love these tires, but do not plan to mount them without a friend on hand.
And they look awesome too.
The tires are fantastic once you get them on the rims....you may need the help of your local bike service center! But one you have them on they are some of the best riding tires on the planet...I use them on my gravel bike.
Very nice tire. They provide a great ride--supple and compliant. They are the nicest gravel tire I've owned. However, they are a pain in the ass to install. You almost certain will need another set of hands and tire levers to get these things on the rim.
