After 40,000+ km on mountain bike style SPD clipless pedals, I’ve finally made the transition to “proper” road pedals.
I’ve had regular SPD pedals on all my bikes and never had an issue. I don’t feel like I’m losing any watts in power transfer, although it’s hard to quantify that one. I like that the metal SPD cleats basically never wear out and you can walk easier. So why the “upgrade” then? Well, actually I don’t really know. It just seemed like time. I’ll keep the old shoes/pedals for use on my winter/turbo bike.
The larger contact patch and cleat size of the road clipless pedal and shoe combo is supposed to give better support, increased efficiency and higher overall comfort. The soles on road shoes are usually much stiffer too, the ones I bought rate at 10 on the Shimano shoe stiffness scale, as opposed to 9 on my older shoes. Not exactly an earth shattering difference but I guess it’s all about those marginal gains!
Does size matter? Road cleats VS mountain bike SPD cleats.
And yes, I pretty much bought the same shoes as I had! My Shimano XC7 mountain bike shoes have been replaced with the road equivalent, RC7 shoes.
With only a single 100km ride under my belt using the new shoes and pedals I have no complaints, but that’s not enough time to give any true judgements yet. I’ll let you know my thoughts as I rack up a few more rides.
