    Shimano M9 Flange Bolt - 8070 hydraulic brake line

    Is the the M9 Shimano flange bolt used to hook up the hydraulic brake line on the new Ultegra and Dura Ace shifters proprietary or is it available somewhere other than Shimano, like at a fastener store? I got stalemated last night putting together my new/old bike when I realized the old line fittings are different. Only place I've been able to find them is Ebay as part of a kit from Shimano or individually from Asia.

    Is the brake line the same size as the old or do I need to convert that also?

    From years working in manufacturing, the few instances where I've encountered M9 bolts have all been proprietary. I've never seen an M9 thread on an off-the-shelf piece of hardware. In fact, this thread is so uncommon that you pretty much need to go to the full unabridged Machinery Handbook to even find specifications.

    Thanks, I'll just order a couple from Ebay I guess. Couldn't find them anywhere else without buying the hose kit which I don't need.
