It's a decent setup as it is for my purposes. I swapped out the Selle Royal saddle for a WTB Pure V Pro, have snap-on fenders for wet weather, mounted a Cateye computer, and just bought a pair of Crank Brothers Mallet 1 pedals to replace the junk Wellgos.
I've owned a Felt 80, but bought another house to rebuild a couple of years ago that put an end to longer rides. I sold it, and get wistful about it every now and again. I've promised myself a new road bike for my 70th birthday as a goal to completing the house reconstruction.
