I'm having a grand time riding my MTB. I'm also spending an inordinate amount of time looking through tons of different threads, reviews, and other online outlets about all things bike. It made me wonder, if you could only have one bike to do all or most types of riding, what would it be? I know I've missed super specific bikes like cyclecross or time trial, but that's what the "other" selection is for. Just a little something to think about until the lifts spin!
I have both a 1x Gravel bike and a MTB All-Mtn bike. The Gravel bike gets more use because I use it on pavement as well as some singletrack. It is a super versatile bike since you can change its capability by swapping tires. The MTB is really more fun on appropriate trails.
