Thanks, sounds like a great idea, have you a link to an example? The dropout takes up a fair bit of the corner so it might be tight for space, but if it saves weight it would be worth a go. Any info would be appreciated
some old Gary fisher and Klein frames had mount on the chain stay with the brake calliper sitting in between the chain and seat stay triangle.
neat solution but there are few callipers of the correct shaoe that will fit there so choose your calliper first!!!
below is how I used a Magura front calliper
(the only one I could find that would fit but they may be others) with my DIY adapter; it works very well in fact
but as the bleed screw is below the inlet, the calliper needs to be removed from bike in order to be bled (a minor inconvenience).
another suggestion wold be to make use of the axle drop out as a mounting point; that would make your adapter less clunky.
have you looked into getting a bracket welded on - that would be the ideal solution.
