4 seasons ago I purchased my first complete drive train since 1986 when I picked up a complete NR groupset from Oschner as a leftover. Rode the heck out of that NR group for many decades and finally the old knees said "NO MORE" very loudly. Picked up 11 speed Chorus deraileurs, Record brifters and crank and put 'em on. Although not as beautiful from an aesthetic point of view, the parts are nice looking in their own right and look just fine on the bike. The big thing is that the thing shifts perfectly every time and I don't have the chain rings rubbing the front der. when under load like the old NR did. I love this new old stuff.
