I wouldn't have bothered "correcting" the Sunday either, but that's a very dedicated project and I respect the effort! Very cool and nicely done. Hugely improved them. I took the time to try both wheel sizes back to back on the exact same frame while resetting geometry to keep all other factors consistent (or as consistent as possible) before making the switch. Tested over a mixture of bikepark runs (not a single track, not just a few runs, not just a few days - extended periods of time on both setups back to back). I don't think anyone else here has done that except buckoW. I have nothing to sell, so the experiment was purely for me to decide which was better and which I'd keep running. My conclusion was that 650b made most riding less painful and more enjoyable, on top of being flat out faster. With that said, I also like rubber compounds that grip, so my opinion may be worthless.
