Hello, I recently purchased the Roam 2. It is my first bike of this kind. I'm quite satisfied with the way it rides on the street, but offroad could be a little better. First of all, the tires. They spin like crazy in any moist dirt, although they're great on the street. They come with 700c wheels stock, but I'm wondering if I could put 29"ers on it?

Also, the suspension fork isn't great. I would like to upgrade it to an air shock suspension fork. There isn't a lot of suspension forks for 700c wheels. Most of the ones I see are for 29" and 650b. Would the 650b fork work with 700c wheels? Would 700c wheels work on a 29" fork?

Also, if I were to switch the fork or the wheels, would it be difficult/possible to use the same discs and brakes?
