I have been running on the G1 Allround for about 17,000 miles on my Cannondale Slate. they tend to last for about 2000/6000 (rear/front) miles if they dont get damaged beyond repair. I have had tread separation from the carcass from (I believe) hard front braking on rugged material after only ~600 miles, a few pinch flats that ruined the tire all together and they tend to loose about 10 PSI between rides. This newer version so far has not exhibited any of these issues after 850 miles. The tire felt a little heavier out of the box and the outer tread material seemed different, maybe thicker on the sidewalls. in either case, the newer version so far has not leaked as much as previous tires and the tread seems solid. The overall ride on these tires (great traction, smooth ride) is fantastic, which is why i keep coming back to them.
I bought these (2.25s) last spring to throw on my Wi.De. for summer riding, but never got around to it until early fall. My first impression was that they were fast, but also pretty hard. I was running them a bit above 35 psi (I'm 175 lbs). I gradually lowered the pressure to where I now run 25 in the back, 20 in front. Still crazy fast, and now soak up all the rough stuff.
The wet season is here in the PNW, and I thought I'd be eager to put my Racing Ralphs back on, but so far I'm pretty happy. I have them on Astral Outbacks, and they hold their curved profile nicely.
All gravel tires sacrifice something, and these are no exception. Downsides are: cornering in loose gravel or mud, climbing in wet leaves and mud, and running over grass.
If you want a crazy fast tire, and don't mind a bit of control loss, these are a great choice!
I have been a fan from afar of the G-Ones and recently bought a bike with a pair of the smaller ones. When my gravel bike Thunderburt had multiple punctures in the wider version I thought what better place to try then Bike Tires Direct and the tire I have been really wanting to give a shot are the wider G One All Arounds. I found the tires to be almost as fast as my road slicks and defiantly faster then the Thunderburts on the road. Going off road there was no comparison to slicks and they were not quite as good as the TBï¿½s but of your doing any mix of road and gravel I think these are it. The TBï¿½s were a little to noisy and slow on the road but shined on single track. The G Ones were better on road and gravel and good enough for the singletrack I was using this bike for. Anything more and I would want my MTB regardless. The only complaint I have is running tubeless they got a small hole in the seam down the middle that is very hard to plug. The tires have well under 100 miles on them and certainly could have hit something but finding the leak was odd. A few trips on the G Ones and everything seems fine. I planned a longer road / gravel ride and the night before was going through the bike and added about 10 psig of air. As I was checking the front tire I heard a small noise which turned out to be this small leak right on the seam. I added more Stans, spun and bounced the wheel and got it to seal but then in the am it lost half the air I put in.
I have been riding on the Schwalbe G-One TL EasyMicroskin's for 6000 miles of gravel on my 2017 Slate Force. these tires are really fantastic! they are very light, tubless, and tough as nails! in fact, I am just on the site buy a new rear because I destroyed my current one on a substantial pinch flat that Stans could not plug even with worms (and it bent the hell out of my rim). However, I would say I am fairly abusive to my tires and to have not had a single flat for 6000 miles (over four tires) of gravel is impressive.
I bought these for a Cannondale Slate to replace the slick tires that come with the bike. These are a significant improvement on the dirt without compromising much (if anything) as far as rolling resistance on the road. They are a little narrower than the tires that the bike comes with and there are some 27.5 X 42 tires on the market for those looking for a slightly wider tire. But overall these handle very well on road and dirt.
This is actually a pretty good tire and I have now put a total of about 8k miles on this on the G-1's (a total of 7 rear tires, with two catastrophic blowouts from casing something. Was able to patch enough to limp home. a rear tire will get me about 2k miles if it last to the end. Although I had these two blowouts I continue to wear these because they are very grippy and it was likely that I was too hard on them.
I used these to replace the much vilified Panaracers that come stock on the Cannondale Slate. Those tires were cool in many ways but they really do puncture easily if you're off pavement and man, what a pain to pry them off the rim!
The internet says these are the tires to go to (or the WTB Resolutes) but they only come in 40mm. So far for what I do they are great. 45 in the front, 50 in the back. Good enough grip for the gravel and fast enough for the road...until it gets fast.
I replaced the stock Panaracer tires on my Cannondale Slate with the G-Ones. I ride a mix of paved and gravel trails. I liked the way the Panaracers rode but I was getting 2 to 3 flats a month with them. I saw that winners of the Dirty Kwanza 200 used the G-Ones. Mounted them tubeless with Orange Seal. They sealed up nicely. No flats after about two months. Excellent ride on pavement and gravel. Very pleased so far. Using 45 psi in the front, 55 psi in rear tire.
