The riddlers were easy to install and setup tubless. No issues getting them fitted or aired up. The sidewalls did weep quite a bit of sealant before they eventually sealed up. Took a few days of shaking them up and adding air. After the first ride they were good to go, no more air loss. Great grip off road while not being a total anchor on pavement. Definitely biased towards dirt though. Taken these on some pretty rough singletrack alond with some pretty chunky hravel and theyve held up well. I would recommend for anyone whos more than 50% off pavement.
The Riddler is as described! My go to tire for all around use. In combination with my Knight Composites 35 TLA wheels, they mount tubeless easier than most others i have used. Only complaint is that the tires may wear out in pavement quicker than I'd like, but probably due to a higher use on the tar than they were designed.
I have a set of these with probably 200 miles on them by now. I've had them mounted tubeless on two different sets of rims, both known good rims, and they just will not hold pressure. (I use Stan's sealant.) They will go from 35 PSI to completely flat overnight. I expect some loss of pressure, of course, but that's way too fast. It's enough that I don't feel confident that they'll still be holding pressure by the end of my usual 40 mile gravel ride. That's too bad, because the traction is great on dry gravel/fire roads, with predictable push/slide through fast corners.
Game changer for converting my 2019 Ridley X-Night from a Cross bike to a real gravel performer. I switched from the original 32 mm Cross tires to these 37mm WTB Riddlers. It was like I switched to a different sport! Less jarring road feedback and much more confidence on loose gravel descents. So far, I have run them tubed at 60 lbs on Mavic Ksyrium Elite rims. I actually broke a few PRs on downhill segments since i felt much more stable.
I have not ridden other specific competitors to this tire in similar width and pressure, but I cannot imagine much better gravel performance. I am going to run these tubeless on a new Open Up build with Zipp 404 NSW wheels, and will report back if any major differences. (PS, i did not want the 404 NSW wheels for gravel, but the world is sold out of 303 NSW)
I spent an hour in my LBS with a very patient mechanic trying to find the largest off road tire I could put on my touring bike to turn it into a gravel/off-road bike. The WTB Riddler 700x45c were what we came up with. I've been using these for trail riding and in moderate terrain mountain biking (Florida & Georgia) for 2 years. As far as the ride goes, they are GREAT tires. They work great on/off road. But... they always seem to delaminate/fail in the sidewall after about 800 miles (the tread is still in great shape). I contacted the manufacturer after the first one failed and they more or less blamed me. I just had another one fail in the EXACT SAME WAY and so I'm going to see if I can get another brand to work as well. If not, I'll return to these.... but will be less enthusiastic about the value proposition.
I bought these tires to build up my first gravel bike. They mounted fairly easily tubeless with a track pump on HUNT 4-Season wheels (19mm internal). My only complaint (and it is minor) is that they are smaller on these rims than the claimed 37mm (more like 36mm). However, after riding them, I see no need to get anything much larger. Cat-head gravel? Bring it! Peanut butter mud? Sped through it faster than my buddy on his mountain bike with 2.2 in tires. Tarmac? Kept up with my friends on a 30 mile group ride without having to change my wheels out.
Not so much as a scratch on these after over 300 miles, they are just starting to show minor wear. I'm certain I've just jinxed myself by bragging on these tires, but I wanted you all to know they are great!
Have been fixing flats, tires, my bikes for 40 years, three bike tours across U.S. The WTB Riddler tire will leave you stranded, almost impossible to mount onto WTB's own I-23 rim, TCS rim and tire. Managed to work tire onto rim, almost crying with frustration, tried to picture side of road in MT with wind and rain. Dangerous tire. Removed tire, gave both new tires away with warning to new owner to stay close to home.
WTB seems to have solved the porous-sidewall problems (or just-plan "bad sealing") I found with very-early version of this tire, which I purchased elsewhere. The one I bought from BTD is much more reliable.
A nice riding tire. I use it on a CX bike that I use primarily as a commuter in Houston. Roads in Houston very similar to CX courses! Durable, and good on road as well as trail. Wears a bit quicker than I'd expect, but overall a good value.
This is an update to my previous review.
Following puncture issues with the first set, I bit the bullet and re-purchased. The second set lasted for almost 800 miles on REALLY rough AZ gravel without a single failure.
I'm going for set 3 without any doubt
This is a very confusing tire. Inconsistent handling. Sketchiest tire I've ridden since a (oddly enough also) WTB MTB tire 12 years ago.
Set up the 700x45 on a tubeless specific rim, 24mm internal width. Setup went awesome, bead popped right on. Easy to roll the bead onto the rim without levers. Following that experience, expected it to be awesome. But on the way to the dirt it was sketchy as all hell at what I'd consider normal tubeless dirt pressures on pavement. Cornering really felt like the side lugs were going to fold over, of the entire sidewall fold under the rim. Scary. Very drifty. I actually unclipped mid turn on clean pavement as I thought both tires were washing out and I was going down.
Tire wants to go straight. Lean it and it wants to return to center. Turning feels almost like a controlled-fall turn. Tire wants to go straight, have to muscle it to turn with you.
I stopped and aired it way up, some improvement, but shoulder lug squirm still out of control.
I'm comparing this directly to the 700x42 Resolutes I took off (and put back on). Resolute is head and shoulders above the Riddler both in handling on and off road, and straightline speed.
Resolute flies on pavement and no squirm on cornering.
If they'd adopted the Resolute shoulder lugs on the Riddler, it would be a lot better.
Looks sweet? Its a high quality tire and all that, but the dynamics are somehow all wrong. Price is appropriate for the build quality, but not for the handling characteristics.
My only suggestion for improving this tire is improved puncture resistance. Had one suffer a 1 cm cut on the center line caused by simple gravel. I run mine tubeless, with Stans at about 30 psi.
Mounting went easy, without problems, and without a gorilla.
Surprisingly good traction on a variety of surfaces. (No mud yet)
Pretty good float in sand.
Great in the corners.
Very confident feel.
Going from Maxxis Ramblers 40s, these (at 37) are faster on paved and hardpack. The trade-off is reduced shock absorption, which can wear you down on long rides. No problems with traction on my local roads. I do plan to use these as file treads for cyclocross-we'll see how well.
Now the downside. One of the two tires has had 3 leaks, the first one out of the box. Biketiresdirect.com convinced me to keep it, but it's had two bad leaks on the road. The Ramblers never leaked in two years.
These tires were also very difficult to mount on my Bontrager wheels. Have not tried them on any other rims.
I plan to replace these for gravel, and keep them for cyclocross races.
I have these on my topstone carbon and its a great balance for riding on pavement and park dirt trails. I run tubeless on these for about 1200 mi. But was a little difficult installing them as tubeless. Starting to show wear on the rears but I would buy them again.
I use these on my Giant Revolt Gravel bike. I upgraded the wheelset, and put these on the bike and my local bike shop made them tubeless. They work well on fairly loose gravel, great on downhills with more heavy gravel and rocks and have survived more than three punctures with the Stans working well on the inside to quickly seal things up! No sidewall issues. The tread doesn't look too deep, but I run 30 psi on my gravel bike and they work great (I weigh 155 pounds) I would buy these tires again for what I use them for, gravel riding in the Tucson and Safford Arizona area.
Bought this tire as a direct replacement for the tires that came on my Cannondale CAAD X. Got two years of use out of the originals with no flats but the rear tire was slick so I changed it. I ride mostly gravel on town roads and Forest Service roads but this tire isn't too bad on pavement. Still running tubes in them.
No real trouble getting it on the rim but the tire was clearly out of round when I put it back on the bike inflated to 60 psi. Took off the rim and remounted a couple of times with same problem.
Then I read an earlier review that said they needed to get it up to over 100 psi to get it to seat and problem solved.
After I realized having a larger tire in the front was the way to go, this Riddler, in 45 mm turned out to be a deal. And this after prior use of a more traditional (motocross) style tread. Mounted well and casing so far appears to handle the sharp knocks.
I use these tires for commuting in the city. At 37 mm they are supple and sprightly. I'm now running them tubeless. The front tire has far out lasted the rear. Sorry, I don't have a mileage count. I ride a steel frame, which offers a plusher ride.
Im revising my original review. Im changing Almost Great to Dang Good. My original complaint of them being fragile hasnt held up with a second set. Im at almost 500 miles of rough gravel onthe current set without any hint of weakness. Theyre wearing fine as well.
