Picked up a Foes Mutz early this spring with the intention of making it a do it all summer/winter bike.
Been swapping out parts I don't like and so far it's a very impressive bike for sure. I have no trouble keeping up to or accelerating away (on downhill sections this thing is awesome) from the guys I ride with who are on conventional bikes with teeny tiny tires.
10/10 so far!
