Great for gravel, and not a hinderance on the road.
After riding with these tires for a few weeks I am quite pleased. I ride probably 75% pavement and 25% gravel and appreciate the fast rolling qualities of this tire with ability to ride at a variety of pressures depending on conditions. So far so good!
I use on my cross frame which doubles as a commuter. I pump up tire to 65 psi and it gives a comfortable ride.
Originally went w the 33s for tackling the (awesome!) Hoosier National Forest roads. Loved the tires but found them too narrow for some of the loose gravel. Bumped up to the 38s and they are perfect. Expertly manage the slime of sloppy lime dust but also do a better job of floating over loose gravel. Excellent on dry hard packed gravel and tough enough for the occasional bit of singletrack. Roll nicely over paved sections. About 1000 miles without a flat. Have tried them tubeless but the sidewalls leak too much - not sold as tubeless so that's fair. Great tire!
I live in the city with streets and paved bike paths, but I'm at the edge of town with gravel section roads stretching to the horizons through farmland. These tires have been a welcome upgrade over the stock 33mm tires that came on my Specialized CruX. Smoother rolling center tread, knobby on the edges to bite in the loose and chunky gravel, and enough volume to lower my pressures for a smoother ride. Near perfect.
I use this tire to commute(20 miles a day) and also hit the logging roads nearby. Fast on the pavement and grippy on the hard pack.
Great, light gravel tire, rolls fast, stable in corners.
many 100 mile rides no problems yet
I purchased these after experiencing reliability issues with another tire. I found myself riding hard-core gravel and wanted a tire that could withstand the punishment, but still provide good rolling resistance on pavement. For me, it was between these and the MSOs. I ran the Gravel Grinder Race for 8 months with acceptable results.
A few notes Tubeless performance was unsatisfactory. This was disappointing, but they were not sold as tubeless ready, so what can you do? This is the main reason I don't run these anymore, and why i gave only 4 stars. Another observation is those larger side knobbies. To me, they seemed like a distraction. I did not like the way they felt underneath when they engaged. It felt like the tire changed its characteristics whenever in a hard cornering situation (which is where I want it to be the most consistent). Get rid of the side knobbies, they're dumb.
The tire looks good, rolls well, and is reasonably tough. It's a good alternative to Clement MSO or even USH. Do not expect to run these tubeless. I found they wore a little faster than I'd hoped for.
These are exactly what I was looking for. Great for my gravel bike.
I set these up tubeless with Stan's no-tube cyclocross kit on standard rims (Mavic Front, Powertap alloy rear), and have been playing with various pressures between 20 and 40 psi. Have done one long race (107 miles) in Minnesota, and lots of training. Will be riding this in the Chino Grinder (Arizona) this weekend, the AlmonzoRoyal 162 next week, and the DK in June. Hoping the lower pressure will allow all of these to run a bit better than with tubes and higher pressure. So far so good. I'll update if I have any problems.
I have been using this tire since 2016 in the DK 200, Almanzo 100 (twice), Cuban Gravel Crisis and the Tour of Hermann Gravel Challenge to name a few. I finally went tubeless and ordered the TCS this time.
I use my Specialized Crux as a cross-gravel-secondary road training bike and put a lot of miles on the bike. I wanted a good gravel tire that would be able to handle a wide range of terrain and still roll well on the road. This tire has been the perfect tire. No problems with punctures, easy to run low pressures for rough roads, good traction, and rolls well on pavement. The width is very nice and the key to this tire. On 25mm rims the tire measures around 40mm and that is key in its ability to maintain traction on really rough gravel roads. The side knobs are nice when you corner as you start to slip and then they kick in and you get the much needed traction. I have not used this tire tubeless.
I trained on these for several months and several thousand miles - mostly on pavement - leading to this year's Dirty Kanza 200. Then, I mounted a new set for the race itself. On pavement, these tires run fast. I did group rides on pavement with my roadie friends and stayed in the lead group. No problems. In fact, I still hold an 8-mile paved Strava KOM with these tires and couldn't beat it last weekend on my 25mm road tires on my road bike. In the Dirty Kanza 200, I think these are the perfect tire. Excellent in all conditions, including loose gravel, big gravel, sandy dirt, and the rough, rocky descents of DK. Very stable. Excellent traction. Always lively. And NO FLATS! I weigh 170 and I used 5055 inflation pressures.
Many people rave about this product but I had a disappointing experience. One of my tires had a bulge that was big enough to be noticeable from bike-mechanics' eyes, and annoying when riding on a paved road. Otherwise, they felt like a great choice for gravels with a very supple feeling and a good balance of low rolling resistance and traction (but I only rode 60miles with them). Thankfully, the customer service at BikeTriesDirect.com provided me with Clement MSOs as replacement (because these were already sold out) right away. I am very happy with MSO. If you choose these tires over MSO (and I can see there are a few reasons to do so - slightly narrower profile (better tire clearance), lighter weight, familiar tread patterns (for CX cyclists), etc, I would make sure the tires are perfectly round before riding.
Put 400 miles of gravel under them so far and no flats. They are fast rolling and corner well with the large side knobs. Surprising grip while climbing on gravel. The sidewalls are supple and the tires feel great at the recommended 45psi
These are the best tires I've found for riding gravel and dirt roads. They have a tall/narrow profile so they take a lot of the edge off the roads but still roll pretty fast. I can feel the weight when climbing but otherwise don't feel much slower on these than I do on my road bike running 23's. Not good in mud, but good enough on dry singletrack as well.
They do wear somewhat quickly on pavement, rotated after about 500 miles. But I haven't found a tire with any kind of tread that doesn't.
Used these tires with Challenge latex tubes for two 62 mile gravel races, Barry Roubaix and Rough Road 100. Inflated them to 45. Very comfortable ride. They roll super fast on all surfaces. While others were flatting over a particularly rough section I was fine. These are my go to race tire. Of note, the rear tire is wearing very fast. I have done some, not a ton, training miles on the road but am still a little surprised how fast the center tread is wearing. I have a set of the Clement LAS tires that have way more road miles and show little signs of wear. Lastly, while advertised at 38 I'm not sure they measure out that wide and I'm using the Industry Nine i25 wheelset which has a bit rider rim.
When I got my cyclocross bike I primarily got it for gravel and after riding with the stock 32 tire on gravel I decided to try something different. The stock tires walked a lot on gravel and were slow when I was on the road. I read a review of the Gravel Grinders by Guitar Ted and decided to try them. I have rode about 500 miles on them and I love them. No more walking on gravel unless it is very loose. They are fast on the road as well despite their size due to the file tread pattern in the middle of the tread. I had a lot more control on mud as well with them. Mud does like to stick to the sides due to tread on the sides. I highly suggest them and I haven't found anyone who doesn't like them.
Rear tire got 2 punctures (both sealed with sealant) within the first month of use. One was on rounded fine gravel, second on rail trail. I liked the ease of mounting and sealing, but 2 punctures on what I'd consider easy gravel have me wondering about long term durability and getting stuck in the boonies.
