Has anyone built a 1x7 drive-train? I do mostly trails mix of climbs and falls and rolling single track. I'm trying to spec my winter build and can't afford new wheels yet. But with getting a new frame, crank and BB are in order. SO I'm thinking build it as a 1x7. 1 on the new crank (32tooth, same as I use most often now). And the 7 on my current rear wheel. It's a freewheel that was on my Meijer bought Mongoose. Frame, wheels and BB are all that are left on it that where on it new. It started life as a 29er Impasse HD.
Any thoughts on this idea?
