    The allen key fitting type nut (that fits into the counterbore hole in the back of the forks) that screws onto the stud/mounting bolt, can be bought separately in different lengths. Some companies (Sram) supply 3 or 4 lengths of nut with their brakes. Your LBS should have a selection.

    Steel dropouts are malleable at room temperature and are relatively easy to deal with.

    Titanium alloys (alpha beta alloys) are not so malleable at room temperature.
    However just on the basis of looking at the picture the titanium drop out appears to be malleable at room temp. So it must be Commercialy Pure (CP alpha structure).

    So, it probably will be possible to straighten it out at low temperature.

    http://www.alloysinternational.com/commercially_pure_titanium.htm

    "Commercially Pure Titanium contains the lowest oxygen and iron levels, producing the most formable grade of material."

    http://www.kobelco.co.jp/english/titan/files/details.pdf
    "Commercially pure titanium is stable for use in the temperature range up
    to approximately 300ûC due to its specific strength, creep resistance, and
    other properties."

    "Low temperature characteristics
    Neither commercially pure titanium nor titanium alloys become brittle
    even at extremely low temperatures." Titanium alloys are just not so malleable at low temperatures.

    A remarkable photo, normally when trying to bend / distort titanium (alloy 6/4 etc) that much when cold it just snaps. So it is possible that it is commercially pure (the dropout that is, not the tubes).
    It is possible to heat titanium to reshape it, as long as you stay well below 800 degrees celsius. Titanium will readily combine with nitrogen at 800 degrees c and above.
    There is the problem of forming an alpha case on the metal (crystaline structure) when heated, and titanium does not look pretty after heating in air (or any active gas). Therefore a possible way to heat it is in the shield gas (argon) of a TIG torch.

    It is therefore:
    1 Try to bend back cold and it might snap and it will not look great.
    Hold the gear hanger very firmly in a vice and pull the frame around till it looks OK.
    2 Try heating it with TIG arc in argon shielding (if you can find anyone to do it) not going to be easy, or look pretty.
    3 Get the damaged part only removed and a fabricated replacement gear hanger welded on, again not going to be easy finding someone to do it.

    Ceeway might know someone to do it.

    You will need to know what the parent metal alloy is, probably either :

    The digit "6" as in 6xxx designates magnesium and silicon as the major alloys
    The digit "7" as in 7xxx designates zinc as the major alloy.

    Then have the right filler alloy to match.

    7000 series alloy will age harden naturally without any need to heat treat.
    6000 series alloy can be heat treated to age harden. Local heat treat can be used on a repair.

    Just look in yellow pages for someone that welds aluminium, and ask to see some of their work.

    The Cerit is similar if not the same insides as the Onyx hubs. The tools for the rear is just a pair of cone spanners. You will find it possibly just needs a clean. But if the bearings do need renewing then it will cost whatever the LBS charges.

    Why narrower tyres?

    According to Schwalbe:
    "Why do wide tires roll better than
    narrow ones?
    The answer to this question lies in tire deflection.
    Each tire is flattened a little under load. This creates
    a flat contact area.
    At the same tire pressure, a wide and a narrow tire have
    the same contact area. A wide tire is flattened over its
    width whereas a narrow tire has a slimmer but longer
    contact area.
    The flattened area can be considered as a counterweight
    to tire rotation. Because of the longer flattened area of
    the narrow tire, the wheel loses more of its “roundness”
    and produces more deformation during rotation.
    However, in the wide tire, the radial length of the
    flattened area is shorter, making the tire “rounder” and
    so it rolls better."

    Some of the cramp symptoms that some people are describing are maybe to do with the centuries old not to be questioned conventional wisdom of ball of foot over pedal axle style of pedaling.
    Maybe not quite the same as spending hours at a time trying to do heel raises but pedaling with your toes/ ball of foot style is going to be a challenge for some of the smaller muscles in the legs.
    It does require some of the smaller stabilizing muscles in the lowerleg to do a lot of work that they are not suited for.

    If you move you foot slightly further forward over the pedal (if using clipin pedals then move cleat back on shoe) and possibly lower the saddle slightly then you can at least fell the difference in effort and the way that the larger muscles can be used more. Possibly this is of more benefit in avoiding cramp than messing about with salt intake.

    "The most widely held belief is that cramp is due to dehydration and the loss of minerals such as sodium, potassium and magnesium. However, if this were so, then presumably all muscles would be affected and not just the large leg muscles, as is generally the case. "
    "Another misconception is that lactic acid (melksuur) build-up causes cramp. This is patently incorrect. High levels of lactic acid in the muscle contribute to fatigue and the inability to sustain a particular exercise intensity by interfering with muscle contraction. On the contrary cramp is a sustained muscle contraction. "

    Lamb might be one of triplets, and its mum might be struggling, possibly.
    The ewe in there might have lost all its own lambs with the cold and rain etc, so it might be the lambs only chance.

    Create your own bluebell wood:
    first take wood then add bluebell seeds.

    Either:
    Bluebell(Wild Hyacinth)Hyacinthoides non-scripta

    or

    Scottish Bluebell (Harebell)
    Campanula rotundifolia
    (aka Gowks Thumles)

    Scottish wildflower seed packets & meadow mixtures

    Yes LHM might be yellow but it will be just as good as more expensive bike oil.
    If its good enough for Rolls-Royce, Bently and Citroen cars it will be OK for Magura brakes.

    Heavy legs?

    A uniquely French condition…… surely?

    http://news.bbc.co.uk/1/hi/programmes/from_our_own_correspondent/7779126.stm
    "Correct me if I am wrong, but have you ever heard a British person complain they are suffering from "heavy legs"? Fascinated by a malady to which British people appear immune, I went to my local pharmacy and asked the smiling young chemist if she could advise me on remedies for heavy legs. "

    "Curiously though, he has noticed that since the French health insurance companies stopped paying for heavy legs remedies a couple of years ago, consumption of these products is now one-tenth what it used to be. "

    How heavy are your legs?

    Might not be ideal. But, if the fitting to the lever is the type that you are looking for then maybe possible to just swap ends round. So 90 degree at lever.
