I took this out on short ride to the store tonight. I've had a few drop bar MTBs,a few "Track" bikes a few SS Road bikes and quite a few SS MTBs. O can honestly say I had more fun on this bike in that short ride than any other bike. I bunny hopped over a median while on the hoods and still put it a little sideways. I'm going to put my Fixed/free wheelset on it to run it fixed when I want also. If you run a 27.5/650b MTB then you can run 29x2.0 tires more often than not. My wheels are 700c with a 35c Continetal Cyclocross Race in the back and a 42c Specialized Trigger in the front(Aluminum Kona P2 fork is stiff) and both have lots of room left. Go 1 size down on an MTB frame to keep a similar TT length and adjust with the stem after that. Understand what it is you really want to do,I wanted an N-1. A do-all bike isn't easy to build if you don't understand how to ride Road/Fixed/SS/Trail.
