N.Wood Posted May 30, 2007 Report Share Posted May 30, 2007 You'd need to use a C2 lever, as the existing Magura setup is a closed system and the new Mono/Mini systems are open.Contact Pete Wright for any help, he did it. Quote Link to comment Share on other sites More sharing options...

They did an O2, an Open 2 but that'd be useless for the above reasons. Quote Link to comment Share on other sites More sharing options...

Ali C Posted May 30, 2007 Report Share Posted May 30, 2007 it is possible, but it feels sooooo bad, its not worth doing! You will have to find some new seals to suite mineral oil to go in the hope lever. The piston ratio is so small that the lever is spongy as hell and you have to have the pads setup pratically touching the rim the whole time.either get a maggie or deng brake, or be extra happy and get a vee.

RobinJI Posted May 30, 2007 Report Share Posted May 30, 2007 It can and has been done with a C2 lever, as said or an XC4 lever. You would have to use a crossover style barbed fitting on the main hose which should connect straight to the C2 lever if there the straight fitting. Or you could use a shimano 90deg fitting on the maggie hose for the XC4 lever. Also the system would need to be run with water, due to hopes using dot 5.1 and maggies using mineral oil.The main problem however is that maggie's use a 15mm master cylinder if I remember right, while hopes only use something like a 12 in the old levers, so there is a much higher mechanical advantage. While this should mean immense hold and power, It also means your rim has to be impracticaly straight, and you'd need one serious booster!If you've got the bits lying around give it a go, but don't be too disappointed if its not amazing.
