    Hey Fishkens,

    Did you get that? It's OK to use steel braided brake lines again. I just want to make sure because you were really concerned about this.

    Any room for a few contrary opinions?

    My brake guy makes and proof tests lines, and takes great delight in demonstrating on his proof testing machine that the rubber hoses available to him today are stiffer than SS braided teflon lines.

    Rubber hoses have improved a lot since they started fitting them 80 years ago.

    If you doubt this next time you pass a open cut mine pop in and have a look at what is on the high pressure hydraulics on the 350 ton excavator that is bulking out the hole - it wont be teflon braided.

    I was a fan of Avon tires too but when they went from $230- a pair to $370- overnight here in Oz I changed to IRC Durotours which I find just as good if not better.
    They come in the right sizes and work fine at the origonal pressures the forks and shocks were designed to work with.
    They stick well, have a nice rounded profile , so stability and turn in is good , and in Oz they are half the price of the Avons.

    IMHO The trick with the Ate calipers is getting them really free on the pins, so that a good hard squeeze of the lever aligns them, just like it says in the 75/7 riders handbook. Dont know when the nonsense of setting them up with a string line/chalk came in.

    If your undertank M/C is working properly going to a handlebar M/C will be a retrograde step unless you go to a very small M/C - remember the lever on the undertank M/C has about a 3 to 1 leverage on the piston.

    With twin Ates a 11 mm handlebar M/C gives good power and feel, with minimal lever movement. If you know how to bleed brakes, of course.

    Problem with the Ates is getting decent pads.
    A large part of the improvement with modern disks comes from the fact that modern pads are designed to work with them, but these compounds are hard to find in Ate pads, so you dont get the full benifit from the disk swap.

    There isnt a lot wrong with the OEM shocks, unless you compare them to the big buck Ohlins.
    Until recently the damper units alone were available from Motobins or Motorworks, at a sensible price.
    If you need replacements the Ikons have stood the test of time, but they are are not worth fitting if your existing shocks work OK and you just want an upgrade.

    It seems to be the never ending story. Room for everybody here. I think the best brakes out there might be on the bikes that have attention from their owners. I do appreciate that my under tank MC is correct again. I was not going to change it because of expense and trouble. Now you have dealt me another trump card for the OEM set up.

    The idea of "really free" caliper pins is well expressed. I have always done this and have no trouble with alignment.

    But an 11 mm MC on dual 40 mm Ates seems a bit extreme to me. Certainly makes the 13 mm not seem so bad tho.

    Guzzi used the 11mm M/C with two twin 48 mm piston calipers without any problems, so it should work OK with two single 40mms.

    The usual comment from folks who ride my /7 is-
    "nice to ride one of these with front brakes that work- what have you done to it" .
    But I have great difficulty convincing them that there is a 11mm M/C in there, as the lever movement is not noticably different to any other size cylinder, and probably less than most.
