  1. After investigation, I thought would go to Nitto 26mm bars and Nitto
    longer Stem instead of introducing threadless stem different company
    componenet interface issues. Nitto quality was the biggest deciding
    factor to change, as Sheldon suggested earlier, for my 1971 Raleigh
    Supercourse.

    1. Looking for about 2" higher bars on stem, so are there different
    heights are just one Nitto Technomic stem with different stem bar
    depth reaches? Anyone know the range of bar height increase with this
    stem?

    2. If have about 90cm stem reach on my low stem now, how would I
    estimate what would be best depth, just approximate 90-110cm for an
    average? Just sit forward or backward on seat for brief periods to
    simulate reach?

    3. Until I put Scott Mathauer rust pads on Weimann caliper, which were
    stock on Weimann calipers, never knew how good the calipers and levers
    really were. Is there any way the 7/8" or 15/16" handlebar clamp on
    Wiemann levers will fit 26cm Nitto bars (up to 3.7mm dia difference in
    clamps)? Or what would I need to do, other than have Tektro 200A as my
    backup plan? I would really like to keep the Weimann levers on the
    bike if possible.

    Thanks!

    I thought the bar diameter on the old jobbers was the same as the new?
    I didn't have a problem mounting circa '77 Shimano kit on a new
    Ritchey bar a while back. I now use the 200A levers and really like
    them. Fair warning: they're big, so throw you forward another
    centimeter or two when riding the hoods. If you ride the hoods a lot,
    you might want to get a slightly shorter stem. Nashbar's got their
    house levers on sale for $15 with a spare set of hoods, they're more
    of a traditional shape. Also, Cane Creek makes some rebadged 200As
    that have gum colored hoods--which might look nicer on a vintage
    bike..

    Landlotter,

    No, the bars are 22.3mm, an old Raleigh unique feature. The brackets
    are just bent straight pieces with holes, so hopefully Loose Screws or
    even LBS can help me out on bracket. The reason I like tektro levers
    are they have quick release, campy brake copy, and Cane Creek hoods
    are softer: feel better, but wear out faster. But I really want to
    keep Weinmann brake levers since the brakes are perfect now, and want
    to keep all angles exactly the same. I just need to hook new cables in
    them, mainly to reroute cable over handlebar for direct entry into
    noodle. But (finally) figured the Nitto stem/bars was the best way to
    go, so why not do it at same time?

    I appreciate the observation on hood distance. Don't really ride the
    hoods often, but sometimes I do and they do feel a little close now
    that you mention it. Maybe that is one of the most important factors
    in fine adjustment of stem depth. It will just take allot of hard
    thinking I guess without simulating it somehow or trial and error.
    Pretty complicated interfaces and never seen anything published to
    date on how to attack the 'fit' problem. First, I need to address
    Weinmann Lever problem, and go from there.

    Thanks for your astute observation!!

    Nitto Technomics are all the same height, come with different reaches.

    There's really no sure-fire way to do this, because you don't even
    know that the 90 mm reach was ideal for your body to begin with.
    After all, you wouldn't be replacing the stem at all if you were
    comfortable.

    I usually use the FitKit for this, but that's not something that can
    be done over the internet.

    Back in the day shops used to stock the clamp bands in both sizes.
    Might be hard to find these days, and, in my opinion, not worth the
    effort. Switching from the old Weinmann levers to modern levers such
    as the Tektros will make a BIG improvement in braking, possibly more
    than the upgraded brake shoes. If I had a Super Course the levers
    would be the first thing I'd replace.

    Funny, I've upgraded a couple vintage bikes from 70s 600 to the R200s,
    mainly as it's often cheaper than sourcing new hoods--but I've not
    noticed any palpable increase in braking power. I know that I *should*
    as there is more mechanical advantage, but something in me thinks it's
    lost with the friction of the cable routing. Maybe I should blow the
    bank and spend a tenner on some teflon coated inner cable. At any
    rate, both old and new levers stopped the bike on a dime--and that's
    due to the Kool-Stop Contis you turned me on to. They're the smartest
    upgrade ever for vintage kit. That and big meaty hands, if I can grow
    'em, anybody can!

    Thanks Sheldon.

    But even a fit kit would be deceptive, because until you rode with it
    in different circumstances over time, the static fit may not be the
    best fit. If I make a matrix of factors like hood distance, different
    fatigue factors, etc... the best overall close estimate may evolve.
    The reason for the change is not depth, but height mainly; and you are
    right, I don't know if best depth now, and know too short in at least
    one factor Landlotter mentioned. Even that one factor of drop comfort
    can change by moving brake levers up on bars. But best in
    multidimensions makes it hard to estimate, especially considering
    everything will change with higher stem. I have some tools to help me
    estimate different factors. There are too may variables to make
    unifrom suggestions, and like seats, is probably something LBS's like,
    since is keeps customers coming back to find that 'ultimate' solution.
    But there should be a 'natural' order of fit, the same as crank,
    pedal, seat, stem/bars, within stem/bars fit alone - the final
    frontier.

    Landlotter,

    I also wondered about the cable routing tight curves close to bars.
    Eventually, the Teflon will wear off cable, where as regular cables
    routed properly can last a few decades easily. My brakes are like ABS
    now, so I can't see them becoming too much more effective now. The
    Tektros would be nice, especially with the quick release, but it
    'makes' you use the tight curved cables around handlebars. First, I'm
    going to try to fix the Weinmann clamps since doesn't 'look' that
    difficult to change with any 26mm clamp. But like the Nitto stem and
    bars, I may 'have' to switch levers in the end anyway. The stock
    Weinmann brake system down to oem pads, feel so good now and would
    like to keep something that still works so well from original bike.

    Thanks,
    Phil Bailey

    Nitto Technomic stems have far, far, far, far more than 2.5" of
    height. Harris Cyclery says about 2.5" higher than traditional
    stems. That is not a useful answer. What is traditional? My TTT
    Synthesis is farily traditional and it has more height than normal
    quill stems. Its about 2" of height. But the Technomic has far, far
    more than 2.5" of height on it. The Harris Cyclery description is
    worthless. Rivendell lists three different Tecnomic stems. Gives two
    different quill lengths, 190 and 225. Gives two different
    adjustability ranges, 152mm and 210mm. So figure 6" to 8.25" range of
    adjustability. From Min insertion line until the horizontal extension
    is touching the headset. Or maybe until the wedge hits the brake
    caliper bolt.

    Good fitters don't blindly follow the numbers the FitKit spits out,
    they take into account the riders style, priorities and physical
    condition.

    Not sure what tight curves you're speaking of. If you're speaking of
    where the housing goes from the inside of the hood back under the
    tape, that's an issue with DiaCompe levers, but not with Campagnolo,
    Shimano or Tektro/Cane Creek.

    If you're speaking about where the housing exits the tape near the
    middle of the bars, the bend is not severe enough to be an issue, when
    the cables are cut to the correct length.

    Quoted message said:

    Eventually, the Teflon will wear off cable,

    I have never observed this with properly routed cables.

    However, back in the day of exposed cables, it was EXTREMELY common to
    see brakes that were compromised by kinked housing at the point where
    it exits the hoods. This is an area that is highly prone to damage.

    My brakes are like ABS
    now, so I can't see them becoming too much more effective now.

    Can you come to a quick stop while braking from the tops of the
    hoods? That's where the "aero" levers come into their own.

    Braking from the drops is about equal, but the different internal
    geometry of "aero" levers results in much better braking from the
    hoods.

    There are no "26 mm" clamps. The 26 mm is the diameter of the bulge
    where the bars fit the stem.

    The brake clamps you want for aluminum bars are marked 23.8 (the ones
    you have are marked 22.2 for steel bars)

    If you have a helpful local bike shop, see if they have any in their
    junk piles. Many bike shops accumulate a lot of this older stuff when
    doing upright bar conversions on older bikes.

    How do they take into account a half dozen riding styles and
    conditions that you don't know how to verbalize? They must be just
    averaging out known symptoms that may not have worked best, but didn't
    have raging complaints.

    2 different 'good' fitters may have 2 different solutions to the
    different products they may sell. And some fits may have acclimation
    periods to adjust to fit better, when the initial static fit will be
    what fitters gravitate towards.

    I would like to meet a 'good' fitter in person one day.

    hoods? That's where the "aero" levers come into their own.

    Braking from the drops is about equal, but the different internal
    geometry of "aero" levers results in much better braking from the
    hoods.

    I like to be in prone position when using brakes, so I don't have a
    chance in getting thrown over bars. There is nothing to hold you back
    on top of drops. I'd rather be in ready position when braking.
    Otherwise, I brake as little as possible. Its easier just to initially
    grab brakes in down position, than to adjust position in a real
    emergency.

    I'm going to try to fix the Weinmann clamps since doesn't 'look' that
    difficult to change with any 26mm clamp.

    There are no "26 mm" clamps. The 26 mm is the diameter of the bulge
    where the bars fit the stem.

    The brake clamps you want for aluminum bars are marked 23.8 (the ones
    you have are marked 22.2 for steel bars)

    If you have a helpful local bike shop, see if they have any in their
    junk piles. Many bike shops accumulate a lot of this older stuff when
    doing upright bar conversions on older bikes.

    Thanks, as always, for the advice.

    Nitto Technomic stems have far, far, far, far more than 2.5" of

    Great comment, Russell. Rulers are nice too:http://www.yellowjersey.org/TECHNOMI.JPG

    p.s. on better bikes the butt in the column is your lower limit.

    Thanks Andrew for informative picture.
    So then 150mm above the head set lock nut must be Nitto echnomic 225
    stem.

    Great! Thanks for the valuable stick in the mud :-)

    What sort of bike do you have that allows you to ride in a prone

    Ted,

    That's my goal, but not there yet. I don't ride with my hands on the
    brakes.
    I utilize UPS right hand turn heuristic, and don't touch brakes unless
    stop sign/red light.
    And even then will turn right not to stop and loop around when clear
    (usually).
    Most of the time, I'm alternating between several high control hand
    positions on handlebars or aerobars (pads allot);
    and at anytime brakes can be grabbed with a simultaneous, within
    reach, grab.

    Keep my eye behind me with third eye always instead since ride on
    right hand side of road.
    Nothing's going to jump in front of me, but if going by cars entering
    road, I won't mind getting in drops, depending on situation.
    That would be extremely poor posture habits to hold one or even two
    positions predominantly.
    At least a little variation helps, and you can't do that only in the
    drops or on the hoods position only.
    And within about 1.3 seconds, full control braking vs being fatigued
    in drops or hoods position.
    What do you think is safer? Good posture is critical in everything you
    do, especially biking.

    Always riding with hands on brakes is like riding a car with 2 feet.
    Either step on the gas or the brakes.
    both are mutually exclusive imo.

    Of course, YMMV.

    Russellseaton1,

    From Andrew's Nitto stem historical range measures of the max height


    being 150mm over lock nut (assume for 225mm stem),
    150mm over my lock nut was about 2.5" greater than my maxed out 1971
    Raleigh Supercourse. So that is what Sheldon carries, and may be the
    greatest demanded stem.
    I had just round house guessed 2" from holding stationary position
    sitting on bike.

    One optimization method is to go from lowest, usually stock, to the
    greatest offered. Then, in between may be better calculated in greater
    confidence rather than try every model
    size out, unless you have a better way to pin point height.
    But this seems like a height I will be able to hold the drops position
    for relative indefinite period when required.
    Since no one seems to like riding in drops positions for long periods,
    from surveys, stock stems are probably an
    extreme racing position unless you are shorter with long legs and fit
    that style.

    I feel strongly what is sold as 'relaxed' 2.5" higher position is a
    more ergonomic 'standard' position for most people (except short
    people with long legs).
    Its not natural to hump over in an abdominal crunched position for
    breathing, when the aero difference is negligible, and in fact you can
    bend lower easier when not
    forced to take that unnatural position 100% of time.

    Thanks for the heads up. This information may not have never been
    revealed otherwise without your observation.

    The Deluxe one that's 1.1" over standard says clearly, "As with all of

    The two Non-Deluxe that are 2.5" over standard height do not. Just
    from my 2" eyeball static simulation and ad evidence above, my money
    is on the Non-Deluxe, lol.
    Oh yeah, the Power of Sheldon too.

    Well, with closer reach/drop position Nitto 176 bars selected 40mm
    wide and increased 2.5" high of Technomics, most every thing cancelled
    out on drops and main level bar, except for rise. So the determining
    factor for me on stem depth was my aerobars where my ratchet shifters
    will also be. After reading Peter Whites logical 'fit' paper on his
    site, I figured while going up, I would reach out as far as
    comfortably possible: and was too crunched in now anyway. So I had
    figured up to 150mm stem reach (or 2" outward while going up 2.5" from
    stem too, since had 1cm that I could center my seat forward. But since
    130 is max stem, will not move seat forward which is good, because
    feels great at this combination of adjustments anyway.

    So I'm going for the higher altitude lifting Superman profile. Its a
    bird... no its a plane... no its Fat Phil out spinning again :-)
    Bicycle ergo nirvana.
