Loved these tires. Ran these 622-35 700c tires for 3,300 miles at 70-75psi and was pleasantly surprised that they carried my 200 pounds for so long before the rear tire tread started to separate.
They were a little slow...am now running Continental Contact Travel tires on the same bike Trek Verve2 at 60psi and they seem a little faster but then again they are brand new...ask me again next year.
Overall, if they were still in stock then I would have gone with the Kendas again.
A few years back these were pretty good tires. They are robust for sure and have a ton of tire down the center with plenty of tread to keep you moving forward.
I'd only use these for training now-a-days because they are quite heavy compared to the competition. (2019-2020).
I'd say that if you are looking for a cheaper, rugged tire that will keep you rolling these tires can be a great option and they are usually on sale. However, if you are doing gravel races and need to watch weight, these are significantly heavier than other tires on the market which offer similiar or better performance characteristics.
Ive ridden 360 miles of mostly gravel, a little pavement and a few miles of Singletrack. These tires have been very stable in large and small gravel and deep sand due to their size (29 x 2.1). Cornering in gravel is good, havent found the traction limit yet. ^) Rough roads, washboard and mildly rocky Singletrack has been smooth sailing. They seem to do fine in mud, but I havent been in the sticky stuff yet. Speed has been good with them and they roll better than I expected on pavement and do not sound like a truck. Seems like this bike and tire combination will ride well anywhere I want to go. Kendas are little pricey, but they have never let me down. Ive worn out three sets of Kenda Flintridge Pros on my other gravel bike with only one flat. The Flintridge does not come in my size for the new bike, but Im liking the SB8s. Bike is a Trek 920 29r.
I did Dirty Kanza 200 on these in 2017 and they performed flawlessly ... that is after having to send two of them back because of a visible wobble that seemed to come from some issue with the sidewall sticker and the tire. Once I replaced the wobblers they were awesome and performed well for about another 2K miles after the race, to include a couple days of light bikepacking in Vermont. I ran them tubeless on CX tires from Velobuild.com. I just returned from DK 2019 training camp and one of my fellow campers had a new pair set up on his bike and it appears that they figured our how to place the stickers on the sidewall without causing the wobble now - I will definitely replace the standard tires on my new bike with these babies a couple weeks before the race.
