I'm one of the proud weirdo freds who use MTB pedals on road bikes.

I use Speedplay Frogs on my road bikes and they are better than Shimano MTB pedals, IMO. I started with Frogs in 2014 and used them ever since. I use Shimano MTB (XTR M9100) on my hardtail 29er mountain bike... and they are good pedals, but not as amazing as the Frogs. It's a shame Speedplay was bought out by Wahoo... and Wahoo didn't continue the Frog line. Frogs are simplistic, with a brilliant design. Super easy to clip in and clip out, extremely durable, easy to maintain, double-sided and light weight. Perfect pedals that allow me to wear MTB shoes, so I can walk around off the bike with comfort and ease.
