Lower drag (gained 1 mph) compared to knobbies, and one of only few tires that fit on my existing rims. Worked well for driving on roads and packed gravel for a cross-country trek over the pass. Great for commuting to work as well.
I use these tires on my Sage Titanium Barlow gravel bike in a mix of road, fire road, and single track. The set-up really nicely on a pair of Enve 4.5 AR rims and can run low pressures for days when one might be inclined to ride something a bit more technical. I ran them on Lolo Pass with no issues last month and use them regularly on fire roads throughout the Portland Metro area. I've previously run the 32mm version (which lasted all winter and well into the summer in really nasty conditions). Now, I'm running the 35mm version.
Kinda like TP, you'll pretty much always need it. I always keep a few extra tubes in my bike toolbox, well, because it's easier and in my opinion, better to replace flats with new tubes. I see it as cheap insurance. These don't disappoint and since after installing with my new tires they have held the air pressure nicely. I waited to review these until they've been installed for awhile and as I stated, they don't disappoint. I would and will buy again
I'm giving this tire four stars because once the tire is mounted on your bike, it performs well.
However, I had a lot of trouble mounting the tires on my rims. What used to be a ten minute task in tube-land ended up taking me most of the day. Granted, this was my first experience with tubeless tires so it's not the tire's fault I was on a steep learning curve.
I ended up inadvertently ruining one tire by inflating it to the max and then having it explode spraying me and my bike with sealant. Again, mea culpa. I thought taking it up to the max air pressure would ensure the bead would seal. Unfortunately, the bead didn't hold for more than 15 minutes and after it popped, I was unable to re-mount the tire as it seemed like wire inside the tire had been stretched or otherwise damaged. Again, not the tires fault!
I ended up purchasing a Schwalbe tire as a replacement for the damaged one since I couldn't find another G-One Speed in stock at my LBSs. I hope this is useful to someone with a big caveat to not inflate your new tire to its max!
