hmm... I suspect the 'serrated' edges of the Sylvan may necessitate a harder sole than running shoes... compared to the flat platform of the GR9...
Have you looked at the dual sided pedals for clipless and toe-clips?
I don't understand the question. I want something that keeps my feet planted on the pedal and properly oriented. The above pedals and steel cages is what my LBS suggested.
You refer to "clipless". As a suggestion for what I should get? And toe-clips...I don't understand.
