These tires are my first excursion into the tubeless world and I can't be more happier in how easy they were to set up, just a few small burps in the first 20 miles. I like how fast they roll on hard pack and they really hold on in the corners. I also feel my climbing has gotten better (reduced rolling resistance?). I now have over 350 miles on them and they show no wear at all.
I've been riding these tires on the gravel for two years now in 35s, which I chose mainly because I was used to riding cyclocross tires 31-33. The tires have seen a lot of abuse including long gravel rides such as the Gorge Gravel Grinder and they're not showing much wear yet. They've proven to be a great balance of road efficiency and gravel traction (there's always compromises, right?). I'm going to try the 40s on this year's Gorge Gravel Grinder, giving up, perhaps, a little on the pavement for a little more comfort on the long gravel stretches.
I bought these tires for my new bike to do gravel rides, and I must say that they are working as I had hoped. The first time I used them I was glad I had chosen these tires, since there are many to choose from. They ride smoothly and have plenty of grip on the roads.
Great tires set them up on non tubeless rims vuelta rims and they work great no leak Downs no problems the tire feels like it's made 4 gravel and off-road use really feel tje road and soaks up tje bumps seemingly better than my other tires with tubes
Grippy and durable tires but are prone to not seat well at first. The tires go right onto Bontrager 700c rims... too easily. They are a pain to seat due to being so loose on the rim. They are also prone to bulging being lopsided and need to be coaxed kneaded a lot to seat properly. Re seated bead twice but still are not super true and they aren't going to get any better. At high speed the lopsidedness is very obvious. At lower speeds it doesn't really effect ride. These get a meh. Sorry.
Tried to set these up tubeless but could never get a good seal and they would be flat by morning. Kenda says these are tubeless compatible (SCT) but it didn't work for me. I'm going back to a UST tire. I'll still run these with tubes as they have a great tread profile.
I found this tire to puncture easily and then not seal well with Stan's. I also had it delaminate completely near the bead rendering the tire worthless. I likely didn't have 500 miles on the tire when it failed. I'm glad I bought these on sale as they aren't worth full price.
I picked these up about a month ago because I was looking for a durable, lower weight 40c gravel racing tire without giving up traction. These were 490g each (on my scale) and I set them up tubeless on 21mm internal wheels. I expected them to stretch and increase in width, but they seem to be a true 40c. No issues so far with about 300 miles on them. I've tried 20-35psi and I've settled around 27.
Rode and finished the 2016 DK200 on these 40mm gems with no flats on a standard tube set up. 30-50 PSI running pressures with wider tread offers more comfort for long gravel endurance rides on my Warbird. Definitely a contender and viable set of skins for any serious gravel adventure or premier race event.
The Flintridge Pro fits the fast rolling great traction recipe that mixed gravel riding requires. They are a full 40c in width on my rims and I am stoked on their traction, cornering and low rolling resistance getting to and from the gravel. 40c is the way to go!
I do mostly road with a little gravel endurance riding. I'm 250 lbs and am not up to riding 200 mile on a 100psi 25mm tire. The K1152 flintridge pro lets me ride at 65 to 80 psi. I didn't have any flats in 3000mi and it rides fast for a biger tire.
