These are rare touring boot soles and grips, lightweight bindings for free riding that are compatible with walk and alpine soles. The brakes are 100mm, but I also have new 90mm and 110mm brakes, so if you wish, I can replace them and ship them. Please contact me at the time of the transaction. Currently, this model is not compatible with touring boot soles, so I think it's a valuable model. I bought it new and stored it, but I'm selling it because I no longer plan to use it. - Brand: MARKER - Type: Ski Bindings - DIN Range: 3-11 - Color: Black Backcountry Free Ride Thank you for viewing.
