Schwalbe

I've been running a pair of G-ONE RS tires as a 50mm front and 45mm rear (chainstay clearance limit prevented using a 50) for a month of gravel road riding. I moved from the Specialized Pathfinders (38 rear, 42 front), which are hard to beat for speed on pavement, so that's the baseline for my perspective. The G-ONE RS has a smooth rolling snake-scale tread in the contact patch for the pavement and hard pack. These wide tires give me plenty of float for better speed on loose gravel and the modest knobs towards the edges hook up in the corners and climbs of the mostly dry gravel roads I ride.

Caliper measured widths (multiple points) were just 1-2mm under the claimed width, as mounted on my Zipp 404s. They went on very easy on my Zipp rims. I mounted and inflated them with a tube to seat on the rims and let them "stretch" in a warm room for a day before breaking the seat on one side, removing the tube and installing the tubeless stem, adding sealant, and re-seating them with a 16g CO2 cartridge.

Very good tire from Schwalbe. Great price from BTD!

These hard to find two inch touring tires were listed on Amazon, but were Marathon Plus at one supplier and another supplier there had several reviews suggesting they had gotten factory seconds! Bikes Direct had the correct tires with the model numbers I was seeking. They arrived timely and I replaced the MTB knobbies on my Priority Bruzer! Great ride for long rail trails and tow paths! Good rolling resistance and A solid ride. I have put 3000 miles on them with no complaints.

I mounted these on our Bike Friday Pocket Tourists that fit in Samsonite suitcases for air travel.

They were a challenge to mount but I used a tire bead jack that helped enormously.

The marathon pluses are extremely tough and flat resistant...the rolling resistance seems minimal as they are nearly as quick and effortless as the much narrower and lighter Schwalbe Durano 20 x1.1 that they are replacing.

These tires also seem to be a good choice for both pavement and gravel

I replaced the Kenda tires that came with my e-bike, which barely lasted a week. In my observation, these new tires are very robust and built to last, unlike the Kenda tires, which crumbled when I removed them. Installing the new tires was tough, I even ended up bleeding from my thumbnails! However, once on, these tires provide excellent grip when pushed hard.

I do recommend practising safety above all else, as e-bikes can be tough on tires. These tires are CE-R75 certified, which is the highest standard in Europe. I've ridden over a thousand miles on them now, and the wear is minimal, I can still see the factory mould lines. Zero flats and I'm confident there won't be anytime soon.

Comfort is also top-notch; I can ride for long periods without realising how much time has passed. I highly recommend these tires for e-bikes, especially since tire weight isn't a significant concern.
