I agree about if the frame had disc brakes it would contradict what was stated about already existing auto/moto tech.
I looked around and it seems there exists already 44mm rim brake plus tire rims, called Snowcats/Snow Cats . 44mm wide. They've been around since '93 ! http://616fab.com/wheel/snowcat-wheels/ https://arcticcycles.com/wp-content/uploads/Snow-Cat-Rims.pdf So I have no idea what the "new" mtb could be either The Bombadil at the time was the "new" mtb based on the 80's kinda design of mtb's .... so here we have another "new" based on the same 80's kinda idea ? You got me ! The only Riv frame I have is a Bombadil and I ride it mostly on road as I have little place off to ride, but it is a wonderful mtn bikey as-is :) -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
