Long time roadie, novice gravel rider here. I have been trying to get to the bottom of SPD pedal choice in regards to the surface area of the pedals so any advice will be greatly appreciated.
Is there any detrimental effect on power transfer, hotspots or shoes wear and tear because of the smaller surface area on SPD pedals??
I have a choice between Look X-Track Race (515 mm2) pedals and Shimano M540 (unknown surface size but smaller than Look). I’m riding S-Works Recon shoes and to my inexperienced eye the contact area on the SPD pedals is tiny compared to the road pedals so I’m wondering if that is going to cause any problems if used on an indoor trainer.
