I'm looking to purchase some quality flat pedals for my bike. I've been riding cheap plastic ones and they keep breaking! I am currently looking at the Race Face Aeffect since they are aluminum. Any and all recommendations are appreciated!
You'll have some things to measure, and some decisions to make.
First, you need to know what the threads on your cranks are. There's a 99% chance they are 9/16" with a tiny chance of 1/2" thread. You need to match whatever interface your cranks have.
You're committed to flat pedals, which does limit things a lot. Don't rule out clipless pedals, or even combo pedals which offer a flat side and a cleat side.
Even in the flat world, there's also a choice between flat and dished (ie your foot has a little shallow bowl to sit in) And you can choose the surface too, from plastic to rubber, to metal. Most forms have a flat and a pinnned or studded interface too, which can be good or bad depending on your needs.
I suggest you pick a budget amount, and go into your LBS and look at what's on offer.
What are you after? Strength or lightweight?
I have these and they're both. I weigh 105 kg (232 pounds) and have not bent them at all. Probably recommend the titanium axles if you can stretch.
