Schwalbe One goes gravel.

Schwalbe's G-One 27.5" Gravel Tire stays on top of rough terrain with a larger volume and tubeless casing. Low profile knobs practically turn your adventure bike into a rock-cheating cloud, and pinch flats on the rough stuff are virtually a thing of the past thanks to Schwalbe's MicroSkin Tubeless Easy tech found in the G-One's casing. It's made of a high-tensile micro fabric that's vulcanized into the carcass for an airtight seal, even at higher pressures, and it also has the benefit of adding more cut resistance all around while decreasing weight.

Combine this with Schwalbe's OneStar triple-compound rubber, and you'll be carving corners and flying into loose gravel sections without a worry in the world.


  • Gravel specific
  • Tubeless Easy technology for speed, comfort, grip and puncture protection
  • OneStar triple-compound protects against rough terrain

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!

After 4 replacements just got my first flat
by kevin.daly

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.

Nice gravel tire

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.

Not as tough as I would like but fantastic traction
by kcdaly

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.

Replacement for my Slate

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 took off the slicks for winter packed snowgravelpave riding. Needed to pump to 90 on my rims to set the beed, then backed off the pressure for riding. Like these!

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.
