I got the new 2019 version as soon as they came out. The feel of them in your hand is more supple and seems a little softer and tacky than the 2016 pro one. I’m running them tubeless. They went on the rim slightly easier than 2016, which 2016 version has never been that difficult for me. Although they mounted easier, they still created the same great tubeless seal as 2016. I think they stretch a little more so they can mount easier while creating the same seal. The 2019’s are now using the European tubeless standard, so was glad to see that matched my wheels nicely and dimensions seemed to b very close to 2016. I haven’t flatted yet. Even ridden them a bunch in chip gravel rail trails. They do seem more supple and tacky on road to.
Overall, except for 1 issue, I think the did a great job. I was expecting them to test better on rolling resistance, but that’s splitting hairs.
The 1 issue I have is sealant seeping out of the carcass. I have tiny liquid dots all over the tire. I’m running finish line sealant, which is not ammonia based and doesn’t dry when in contact with air. Maybe this is why, but I’ve run finish line for years in 2016 version with no issues.
That being said, I prefer the old onestar compound with microskin compared to the new addix compound solely because of this leaking problem. I am still using the tire and have for months, but next tire I’ll get the 2016 version if available.
