The Mesa 61 has the same thin profile and wide body that the Mesa pedal is known for and built out of a durable 6061 aluminum that's built for grinds, smashing rocks and anything thing else the streets or mountains through your way. To top it off Fyxation added steel replaceable pins that offer just the right amount of grip when you're shredding on your ride. Oh yeah, it was designed to be used with most pedal straps and FRS so unlike most alloy pedals these bad boys will work foot retention.
