So I’m planning well in advance for this, but I want to get an idea for how to set up my fat bike for riding trails in the spring/summer. My Spec. Hellga came with 90mm wheels 135mm/190mm QR and 4.6 Ground Control wire bead tires. My goal is to get a somewhat lighter wheelset with narrower rims to fit smaller tires.
From what I’ve seen I have a couple of of options: 26 x 4.0, 27.5 x 3.8, 27.5+ (2.8-3.0), or 29+ tires/wheels. I don’t know what I would “need”, however I don’t plan on adding a front suspension to my bike as I don’t think it’d be cost effective for me, nor do I know if one would work on my bike. So with that being said I want to see what would be an optimal wheel+tire combo for riding single track on a (rigid) fat bike.
