Don't grovel in the gravel.
Named after the gravel-road laden Flint Hills of Kansas, the Kenda K1152 Flintridge Pro Tire gobbles up loose rock like nobody's business. The fast rolling center tread keeps speed on hardpack, but grippier transition and shoulder knobs provide excellent bite when the terrain gets loose and rocky. This balance of low rolling resistance and traction is enhanced by the Flintridge Pro's dual tread compound that features L3R Pro 60A durometer rubber down the middle and a softer 50A Stick-E rubber on the sides. It's built over a 120 TPI KSCT casing that protects the sidewalls from cuts and abrasions while also making the Flintridge Pro tubeless-ready so you can grab some extra performance and comfort on your next gravel grinder.
700c diameter. 120 TPI casing. Tubeless ready. Folding bead. Available in multiple widths. Claimed weights are 481 g (35 mm) and 515 g (40 mm).

I've tried a few different gravel tires and settled on these. The 40c gives a good ride wgood traction and durability and feels like it rolls faster than others. Im a larger rider and this tire gives a nice ride for me w47-50 psi.
I had been riding Kenda Happy Mediums 40mm and really liked them, but knew my bike could handle wider tires (45mm). I was interested in trying wider tires for extra comfort(lower pressure) and better traction. These tires deliver on all aspects. Plus they are bombproof. I'll be buying more of these.
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.
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.
Mounted these on my gravel bike in late summer before the RPI in Sun Valley. Put around 100 mi on them prior to that event. During the RPI the tires performed admirably. Ran them at 65psi with tubes, I'm 6'3, 190lbs. I tried mounting them tubeless but they didn't take and I didn't really care to take the effort to continue - I don't mind the extra weight.
They are solid and confidence inspiring in the gravel and rough sections and roll well on the pavement despite having a fairly wide footprint. In the dirt they are fine as long as it's solid but if it gets loose they can be a little squirrelly as you might expect from the tread pattern. When cornering on pavement they tend to turn in early when leaned over into a corner which can feel like they are washing out but if you keep your nerve they hold their line. They are also a bit heavy, but worth the protection.
Overall these tire are great gravel tires, good on single track, fine on pavement and I feel like they'll last quite a while.
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.
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.
These are my go to gravel tires. I recently set up my second set (700x35) and mounting is a breeze. Very durable and long wearing tread. I keep them around 40 psi otherwise the side tread can catch a little turning on pavement. I've ridden them on some gnarly terrain, both wet and dry, and they haven't let me down.
Performed flawlessly on the Ohio Erie Canal towpath over many miles leading up to a week riding the Great Allegheny Passage and C&O Canal trails self-contained over a week last summer. Ohio Erie was soft at times from rain and the Flintridge held its grip. Major rain the night before heading onto the C&O Canal towpath left large areas of standing water on the trail for about 23rds of the 189-mile-long trail. Again, the Flintridge performed well under full load. Would definitely purchase this tire again. Oh yeah - no punctures!
