    Dear Sheldon,

    I look forward to the debate over chain streamlining:

    I'm always glad of proofreading help with my Website, I'm a fast but
    not too accurate typist.

    However, when you do spot a typo, it would be better to send me an

    Nice report but I take much exception with this sentence:
    "Nobody rides a singlespeed in terrain mountainous enough to actually _need_
    a rear disc brake."

    I don't ride an SS but the guys I ride with do and since we're on the same
    rides they definitely are riding "terrain mountainous enough". The San
    Gabriel Mtns are very steep and of average height, 5000ft to, well, 10,000ft
    with alot of trails climbing 3000 ft in only a couple of miles. No matter
    how the SSers get to the tops of those trails they still ride down them.
    And I'm sure there are plenty of SSers around the world riding similar
    terrain.

    Woohoo! Was that a 8spd Nexus *rapidfire* shifter I just saw!? I think
    they never did better than the original thumbie for the Nexus 7. I
    liked the feel and the groovy rotary dial. The disc brakes for the
    Alfine group are totally overkill--but why the heck not? It's likely
    going to be ridden by the creme of Amsterdam--they can't just have
    pedestrian roller or drums. We'll likely see this groupset first on one
    of those gorgeous Koga-Miyata, no?

    Totally agree with you on the SS discs. I'm sure some folks can make
    use of such braking power--but I'd reeeeally like to see a return to
    good ole semi horizontal dropouts for bike that use a caliper brake.
    Track ends strike me as more of a fashion statement for street use with
    brakes and even fenders than a practical idea.

    Those side plates are actually tiny zeppelins filled with hydrogen to

    Which says among many other things:

    "Kinda disappointed in Bianchi this year. They continue to believe that
    disc brakes make sense on singlespeed bikes. This year they've got
    three different singlespeed/disc mountain bikes and a singlespeed/disc
    cyclocross bike as well!

    "Using a disc brake means you can't use a flip-flop hub, so you'll be
    stuck with only a single gear option.

    "Also, as the chain wears and you move the wheel back in the axle
    slots, the relationship between the disc and the caliper will change,
    which is a Bad Thing.

    "If you combine a disc brake with an old-fashioned rear-opening fork
    end, as is currently fashionable, you have to undo the caliper just to
    fix a flat tire!

    "Nobody rides a singlespeed in terrain mountainous enough to actually
    _need_ a rear disc brake."

    There's no problem running a front disc if you prefer, but I'd strongly
    advise going for a rim brake in back.

    Of course all generalizations are false, but I'm gonna stand by that
    one.

    I generally take much exception to any claim that any cyclist "needs" a
    particular feature anyway...

    I haven't ridden in those mountains, wherever they are, but I am highly
    dubious that a rear disc brake is actually needed to descend them. I
    have no doubt that a rear disc brake might be nice to have there, but I
    very much doubt that it would be as useful as a flip-flop hub to
    someone who was into that sort of riding.

    The main virtue of rear disc brakes is for use in wet , muddy
    conditions, and such conditions rarely occur at high altitudes, or at
    least that's my impression. Maybe your mountains are an exception to
    this, I dunno.

    I would imagine that the percentage of Bianchi's singlespeed customers
    who will actually ride their bikes in major mountains is a pretty small
    drop in the bucket.

    looks like the Shimano Alfine shift gear indicator is upside down, the
    numbers are upside down. I have the Shimano Nexus on my Bianchi
    Milano and like the performance very much, this looks like a nice step
    up, will be watching for bikes that offer the Shimano Alfine.

    Dear Sheldon,

    The San Gabriels run right up next to Los Angeles.

    I dunno about how wet they are, though massive mud slides following
    forest fires and torrential rains make for entertaining reading if you
    like John McPhee (See "The Control of Nature" collection of his New
    Yorker pieces).

    But in Colorado, things tend to be dry low altitudes--say Pueblo, out
    on the Great Plains at around 5,000 feet, with the cactus, antelope,
    yucca plants, tarantulas, and so forth.

    It's up in the Rocky Mountains where things are muddy, wet, and
    miserable.

    In summer, it rains up there. In fall and winter, it snows. When spring
    comes, the snow melts. People up in the mountains own raincoats.

    The ski resorts are up high because that's where there's lots of snow.
    Down in Pueblo, two feet of snow is a rare disaster. Up above Salida, a
    hundred miles into the mountains, it's not enough to open the Monarch
    ski resort at over 10,000 feet.

    Typical mountain trails in Colorado follow and cross endless streams,
    snowbanks, and bogs. It's out in the foothills where the desert
    conditions are found. The Great Plains are dry because they're pretty
    much in the rain shadow of the Rockies. Damp air from the Pacific drops
    most of its moisture as it passes eastward over the repeated
    north-south mountain ranges.

    For example, I've been riding motorcycles up the front of the Greenhorn
    mountain range for years on the Snow Slide trail. It starts half-way up
    the front of the mountains near San Isabel, climbs about two thousand
    feet, and reaches a huge large flat area on top, near a steep boulder
    field running down the front of the mountain range that's visible for
    fifty miles out on the plains. The rocks are usually snow-covered well
    into summer, so it's known as the Snow Slide.

    At the top, you ride across what's often a mile-long bog as late as
    August to reach the Greenhorn Road that runs along the top of the
    mountain range.

    The trail is the dotted black "pack trail" heading southwest from the
    highway just below
    the red-circled "165" a bit south of San Isabel:

    http://terraserver.microsoft.com/image.aspx?T=2&S=14&Z=13&X=154&Y=1312&W=3

    The trail starts half-way up the mountainside at about 2700 meters, or
    8860 feet.

    The wide bog on top is the huge white area at over 3405 meters, or
    11,170 feet. The solid black line south of it is the Greenhorn Road, a
    wide dirt fire road.

    Of course, damp New England hasn't got any elevation as high as lowly
    Pueblo, and my sister near Boston often mentions curious architectural
    features like mud-rooms, where people leave their muddy boots.

    Fenders, I hear, are routinely attached to bicycles in Massachusetts, a
    fairly pointless bit of frippery for bicycling around Pueblo for about
    350 days of the year.

    But the fenders on my trials motorcycle are very useful up in the
    mountains. After a typical ride, it takes about five minutes to hose
    all the mud off the machine at a car wash.

    Your mountains may be different.

    Cheers,

    Carl Fogel

    I'll be a bad boy and post this redundancy about the Brooks grips:

    quote:
    B.135 is similar to the B.130, with compound springs, but with the same
    smaller top as the B.66-B.67.

    The Brooks handlbar grips look very appealing. Edge-on leather discs
    for good traction. The stack of discs is held together by bicycle
    spokes! These grips have a fairly coarse appearance when new, but can
    be expected to smoothen up with use.

    The Brooks "Aged" saddles have turned out to be quite a bit softer than
    the standard models. Targetted at lower-mileage riders who don't care
    to take the time to break in a standard Brooks. Some of the early
    "aged" models had a tendency to get too soft and too wide, so now they
    are all coming with laced-together adjustable skirts.

    Brooks handlebar grips are mad up of a stack of leather discs, set
    edgewise and held together by two metal caps and three spokes!

  16. That sure came across as rude. Just a head's up, Sheldon, otherwise a
    salute from me, and a virtual slurp from my cup of yerba mate!

  17. Sweet report. Thanks for the effort (of making the report).

    Now the real questions is, I've only managed to get a few strands of
    orange-brownish hair in my beard. How in the world did you get that
    radioactive red-pink glow to yours? Surely, we know you're not the
    superficial type to go for - gasp - artificial coloring? Dites-nous que
    c'est pas vraie! Du colorant? Non...Ca se peut pas...

    Another advantage of discs is that a mildly bent or out of true rim
    won't rub brake pads or freeze your wheel. If you're doing lots of
    jumps/falls/etc, this could be a big advantage.
