I just went back to clipless (SPD) after many years (just got back on the bike end of last year).

Well...Wasted quite a bit of $$$ on Dura Ace, Cyclone, and MKS ESQuartz pedals, clips, and nice Cinelli and Silva straps!

I had forgotten how nice it was to ride clipless I guess. Now I have A520s on the Sampson and M520s on the Pinarello. Methinks I will end up buying something for the Reus eventually (sooner than later probably).

I still have clips/straps on the Super Course, beartraps on the Rockhopper and old Iron Horse, and Power Straps on the PR10 (hopefully selling that this month).

I think clipless is effortless and mindless once you get used to it and you probably wouldn't want to go back.

If anything, it is the annoyance of the cleats on shoes (even SPD). I used Specialized BG Sonoma which is sorta a road/casual shoe and the cleat protrudes a hair...clickety clack...clickety clack. Mountain shoes with tread fare better for sure.

Oh yeah...French threading...the tapping from 1/2 to 9/16 is a non-event. Use some cutting oil (or any oil really) and it will breeze right thru.
