As far as I can work out, the feature that houses the threads and chamfers, plus the threads and chamfers themselves, are gonna be much more expensive to manufacture than one simple piston. The surface finish required for the piston bores also ups the cost significantly - having two of those is gonna be un-necessary. You could also make the body retrofit a current lever blade, saving more cash. I didn't actually read that post though to be fair, I'm fully aware of Luke's situation (he's a customer of ours). I dunno, I'm just trying to suggest things to make it easier. Another idea: http://www.motorrad.magura.com/downloads/M...atalog_2007.pdf Part number, 0120438, Page 24
