If anyone is interested shoot me a message. Fits tyrolia bindings and I believe it is the small mounting plate (fits boot sizes up to 330 mm?). Used 15 days maybe? No issues with it, just upgraded to an actual AT binding setup. THe MFD works a lot better than trekkers, so if you're looking to get out and do some walking, without dropping $450 on new bindings, these are a great introductory option. Located in East Millcreek.
