I got to the same outcome for a year round bike by adding a 27.5+ wheelset to my fat bike. Given the amount of time I ride blue and above trails in the summer (ie not much) this is a pretty good compromise for me.Great outdoor pics. I got rid of my 26x4 fat bike in favor of a Trek 29+ Stache. I had a great time on the fat bike year round, but the Stache is 10 pounds lighter and handles a lot better. But I still suck at hill climbing, although I can climb some hills I couldn't on the fat bike. Don't know if it's my technique. or just poor leg strength.
