I have been using shimano mtb pedals on my road bike for a couple of years now. I have Sidi road shows which take both cleats and i am fairly happy with my set up.
The thing is i have signed up for my first sportive and plan on doing another 2 or 3 after that, i am also awaiting delivery of my new Ribble ultralite racing bike which i have ordered without pedals.
Is there any real benefit in using road pedals over mtb?
i do think the road pedals look a bit better and if there are any "marginal gains" to be had then i would maybe change my set up.
Any thoughts or help would be appreciated.
