The Schwalbe One family provides the perfect tire for the latest gravel bike trend. The smooth rolling G-One profile and Tubeless Easy technology make it a pleasure to ride over forest paths and rolling fields.
We have installed and ridden the 38mm and found it inflates to 40.6mm with the Stan's Grail rim.
If your frame has enough space, select the 40mm version. Larger volume is always an advantage when riding off-road.
I have heard so much about these I had to give them a try. I have the 35MM on my Hakka MX and they are so nice! My first ride was on a gravel, tarmac with a nice dose of mud thrown in. I rolled right through them all with out any issues. Kept good speed and hooked up on each surface better than I expected. The mud was the surprise, nothing deep or sticky but these handled it so well. Well worth the hype.
