Kenda Flintridge Pro Tires: Checkpoint- by Guitar Ted
The Spring we were supposedly going to have was a fast one and here we are in Summer already. Time to update this review with the latest views on this classic gravel tire. If you seem to think you’ve seen a Flintridge review here before, you may have and all that is explained in the “Getting Rolling” post here. As mentioned in that previous piece we will also be hearing from MG, our contributor in Nebraska, about this tire. Let’s dig in……
The Flintridge Pro has some quirks, but is a pretty decent tire for gravel travel.
Tubeless Performance: The views I had on the difficulties I experienced with the ability of the Flintridge Pro tires to be set up tubeless set off a storm in the comments and I heard from many riders regarding the tire and what rims were and were not working well in regard to tubeless set up. Our contributor, MG, also had some comments and his experience was much better than mine. He reported an easy set up, as many readers did. Digging in a little further, it seems that the vast majority of those commenting, and also with MG, were using Stan’s rims of some sort with the Flintridge Pro.
This makes sense in that Stan’s rims have a bigger bead seat diameter than most tubeless rims. This makes the Flintridge Pro fit tight enough to allow it to make a good initial seal when setting up the tire tubeless. The Irwin Cycling wheels, the Arlo GX 27’s on test here, are another rim that seems to play well with the Flintridge Pro. Besides this, the Flintridge Pro seems to have very good air retention characteristics and that is impressive.
The Flintridge Pro was average in terms of wet weather performance and mud pack up.
Ride Performance: The Flintridge Pro has a quirky personality when it comes to ride feel. The puncture protection belts and stiff feeling casing would lead one to believe that this tire has a higher rolling resistance. That I confirmed in my roll down test. On the course I use, which is a steep, paved hill leading to a primitive two track road, I found the Flintridge Pro was at the bottom of the class when it came to roll out. This can be felt while riding paved surfaces as well. It has a “draggy” feel to it, and I find the tire to be unpleasant to ride on pavement.
That high resistance ride feel was absent on gravel, however, and for whatever reason, this tire rolls just fine on loose gravel. In fact, the rougher it gets the better the tire performs. Perhaps this is owed to the tire being designed for Kansas’ Flint Hills region, which has some pretty rough gravel. The dual personality of this tire manifests itself in a smooth, composed ride on gravel. There is a slight bit of lateral instability on the loosest, deepest gravel, but that is par for the course. The Flintridge Pro is actually a pretty impressive tire on crushed rock.
Our tester/contributor, MG, also has been testing the 40mm Flintridge Pro along with its 35mm sibling. MG reports liking the 40 a bit more saying, “Overall, they’re pretty good. I like their rolling performance.” He also has matched up the Flintridge pro with a WTB Riddler. MG comes from a MTB background where mixing and matching tread patterns has been a tradition for years. “The 40 (Flintridge Pro) is a good tire front or rear, but I prefer it on the rear, paired with something like a WTB Riddler 45mm in the front.” MG says it is this combo which he will race on the Lauf True Grit which he is reviewing for us. (See his latest post here) As stated, MG is also using the 35mm Flintridge Pro. He has these on a Singular Kite and stated, “…..they are noticeably faster and lighter, but also harsher riding.” As for nits, MG said he wasn’t as fond of the cornering prowess of the Flintridge Pro tires as he is with other tires with a more pronounced edge tread. The Flintridge’s edge knobs are quite low. MG also said that inconsistencies in the way the tread is applied to the casing appear as wobbles on all the examples he has in to test, both the 40’s and 35’s. I noted a slight inconsistency on one of my tires as well. Performance of the tires does not seem to be affected adversely though. More of a cosmetic annoyance here. Finally, MG reported back that his 35’s measure out at 38mm and his 40’s as 43mm tires. Something to keep in mind if your clearances are minimal.
So Far…… The Flintridge Pro is a tire made to withstand some nasty gravel and paved road gremlins, but with that protection comes a price. In this case, a possibility for a very difficult mounting process, and high rolling resistance on pavement. While hard surface riding suffers from a higher rolling resistance feel, when you hit the rough stuff this tire comes alive. It rides with an uncanny smoothness then that belies its paved riding characteristics. The Flintridge does mount up 2-3mm wider than stated on the hot patch, so be careful if clearances are tight on your bike.
Tread wobble could be an issue with this tire, but it doesn’t seem to affect performance for us. The tread has a good amount of traction on dry dirt and performs in an average sense on gravel. Just what we expect from a tire in this class. Mud is not this tires friend. That said, if you have rough to severe gravel or rock on much of your routes, the Flintridge Pro is up to the task there.
Stay tuned for our final verdict on the Flintridge Pro tires coming up later this Summer in our “At The Finish” post.
