  1. I need to find a 140, -17 stem that won't damage a Reynolds carbon steerer,
    and I couldn't find any info at the Reynolds composites site even though
    they say there is a list somewhere. Can anyone tell me if the newer Ritchey
    stems will work? That's the only road stem in that size that I've found so
    far, and it's got the diagonal slot Reynolds doesn't like.

    Thanks for any help.

    Ritchey stems work well with Reynolds forks. leave 5mm spoacer above
    the stem to prevent crushing of the very end of the steerer.

    How can you crush the end of the steerer tube, if you have the
    compression plug installed?

    Easy. The guts inside the steerer are not at the very end of the
    steerer. If the stem overlaps the end of the steerer and you really
    gorilla it tight, you pinch/crush it. We put 5mm on top of all the
    stems for any carbon steerer.

    Actually, the compression cap is EXACTLY at the very end of the
    steerer, unless you've cut the steerer many, many mm too short. If
    that's the case, then the compression cap won't work as it won't reach
    the steerer tube. It's either at the end of the steerer or not at all.
    Won't work any other way.

    The compression cap (that hard plastic thingy that inserts in the end
    of the tube) certainly does NOT go completely past the end of the
    steerer tube, as it also has to reach beyond the top of the stem. If
    you've cut the steerer so that it reaches within a couple of mm of the
    top of the stem, taking into account the spacers you will use, the
    compression cap will extend into the steerer well past the top bolt on
    the stem and thus prevent that bolt from crushing the steerer. Unless,
    of course, you tighten the stem so tight as to crush the steerer AND
    the compression cap simultaneously.

    Now, I'm sure there's at least one person out there who'll say they've
    done it, but I'll have to see it to believe it.

    If it's so important to have the steerer tube extend beyond the stem,
    what's so magical about 5mm? Why not 10, or 20??? How did this
    mystical 5mm come to be? Is it really reasonable to expect that a stem
    tightened at the end of the tube will crush it, but if you just move it
    down 5mm it won't?

    Peter, I building a bike with a full carbon fork at the moment. The
    compression plug which came with the frameset has a large cylindrical
    portion above 'the guts'. The diameter of this portion is 0.3 mm smaller
    than the inner diameter of the steerer tube. See

    http://home.planet.nl/~holtm072/plaatjes/ScottCR1limited%20006.jpg

    would it be still wise to put a 5 mm spacer on top? I need no spacers
    under the stem and putting a 5 mm on top would be kindda ugly (all
    spacers look ugly). I'm gonna use a tork wrench, so no gorilla tightening.

  7. Too late now as it's been cut for a Thomson Elite (oops). The cap that came
    with the fork is pretty beefy and extends down snugly inside the steerer
    almost to the internal plug supporting more of the collar area. Maybe that's
    a recent fix by Reynolds for the crushed steerer problem, but they still
    sent a flier saying not to use certain types of stems just to confuse the
    issue.

    Can you thread a carbon steerer an additional couple of millimeters using a
    die?

    Ah, but tell me how many crushed steerers have YOU seen?

    Do you know the fatigue properties of a carbon steerer tube?

    Carbon steerer tubes are a bad design! No wait, we've all seen carbon
    steerer tubes, so they can't be that bad of a design...

  9. Please look up the sender of the original post. 🙂

    Please consider last post wishful thinking in lieu of definitive
    information. The top cap I'm talking about goes almost an inch into the
    steerer tube and screws onto a threaded wedge circling the allen bolt used
    for loading the headset bearings.

    I have personally crushed one carbon steerer, and don't want to do it again
    with my new ouzo, or were you gunning for someone else?

    I guess on your but the part that expands to hold it into the steerer
    is not at the end, and the part that is threaded 'should' be a wee bit
    below the end of the steerer, or the cap will hit that before the HS is
    tightened.

    Nah, just making a joke to the newsgroup in general, forgetting the smiley.

    I'm not being pissy. Just questioning your declaration that there's
    something to be gained, besides adjustability, by extending the steerer
    tube above the stem.

    I can visualize it quite well. There's a portion of the compression
    cap that extends into the steerer tube. I thought it was plastic, you
    say it's metal. Not important, except that if it's metal it's probably
    even MORE resistant to crushing.

    So, please visualize this: the steerer tube is cut so that it comes to
    within 2mm from the top of the stem. You insert the compression cap
    into the steerer tube. This cap extends well over an 1" into the
    steerer tube and serves to reinforce the steerer tube well past the top
    bolt on the stem.

    How much force do you think it would take to crush the steerer tube
    PLUS the compression cap simultaneously? I suppose that if you
    installed a stem on the end of the steerer with the top bolt a cm or
    more above the end of the steerer and you did not put the compression
    cap in, you could damage the steerer tube by overtightening the stem.

    With the end of the steerer tube cut just below the top of the stem and
    the compression cap installed I just don't see crushing the steerer
    tube with only the force you could exert by tightening the stem bolts.

    I don't expect that you'd care to demonstrate this on a fork, but if
    you want to prove your point, I've got an idea. Next time you cut a
    carbon steerer tube, put the part you just cut off into a stem and try
    to crush it, with or without a compression cap installed. I'd be
    curious to see just how far above the end of the steerer tube you'd
    have to put the top bolt of the stem to damage the tube.

    I've got a new frameset coming next week. After cutting the steerer to
    length, I'll try it myself. I'll let you know how it works out.

    cap in, you could damage the steerer tube by overtightening the stem.

    With the end of the steerer tube cut just below the top of the stem and
    the compression cap installed I just don't see crushing the steerer
    tube with only the force you could exert by tightening the stem bolts.

    I don't expect that you'd care to demonstrate this on a fork, but if
    you want to prove your point, I've got an idea. Next time you cut a
    carbon steerer tube, put the part you just cut off into a stem and try
    to crush it, with or without a compression cap installed. I'd be
    curious to see just how far above the end of the steerer tube you'd
    have to put the top bolt of the stem to damage the tube.

    I've got a new frameset coming next week. After cutting the steerer to
    length, I'll try it myself. I'll let you know how it works out.

    I seem to understand your description, but let's get the terms right.
    The expander is a two-piece aluminum bit through which travels a steel
    bolt. The lower portion of the expander is partially split into four
    sections, all but save the lower bit, which is threaded for the steel
    bolt. It also has a conical sink into which the upper portion
    correspondingly fits. In a groove around the lower portion is a rubber
    o-ring. The upper bit is threaded at the top to receive the aluminum plug.

    When tightening the steel bolt (5mm), the split lower bit expands inside
    the steerer, anchoring it there. Afterwards, turning the plug clockwise
    (6mm) pulls it down towards the anchor, dragging the stem and spacers
    with it, resulting in preload of the hs bearing.

    Now, as for tightening/over tightening/crushing the carbon steerer,
    that's what the plug portion is designed to minimize/alleviate. It is a
    reinforcing plug for gorilla types who insist on over tightening things
    without a torque wrench, and it is designed (from my interpretation)to
    protect the upper end of the steerer, not the entire stem zone. True
    Temper has a similar concept going with their glue-in reinforcement
    plug, but that covers the entire stem clamp zone of the steerer.

    The best way to avoid crushing problems (admittedly difficult for a
    thoughtful person) is to tighten the stem "just enough". That is, so it
    doesn't move in normal use, or loosen. In lieu of that, use the torque
    wrench. Leave as little room above the steerer/below the top cap as
    possible to maximize strength, usually no more than 5mm.

    As for your 14cm stem, I don't know of any limitations from Reynolds.
    Nonetheless, I'd follow the instructions (in your literature and above),
    and not worry about it. Now, where you can find this stem, I don't
    know. Several makers make a 140mm stem, but no-one I could find in 73^
    (aka -17^). Why not go for a 80^ and lower it a bit?

    If the carbon steerer doesn't go past the clamp portion of the stem,
    but is partially below the end of the stem, it can be crushed...with
    the top bolt being overtightened. If you can't visualize this-ohh
    well....We are not keen about paying for a carbon fork we goon up.

    I'm not being pissy. Just questioning your declaration that there's
    something to be gained, besides adjustability, by extending the steerer
    tube above the stem.

    I can visualize it quite well. There's a portion of the compression
    cap that extends into the steerer tube. I thought it was plastic, you
    say it's metal. Not important, except that if it's metal it's probably
    even MORE resistant to crushing.

    So, please visualize this: the steerer tube is cut so that it comes to
    within 2mm from the top of the stem. You insert the compression cap
    into the steerer tube. This cap extends well over an 1" into the
    steerer tube and serves to reinforce the steerer tube well past the top
    bolt on the stem.

    Tell ya what, you do whatever you want. We at the shop, than install
    hunderds of forks, will continue to do what we do cuz, it works, and
    not all 'compression plugs' are like the Ouzo Pro one. Those 5mm aren't
    very heavy, BTW. This is kinda like those that whine about 36 spokes
    being 'overkill'...There is no reason NOT to install the way we do,
    there is not reason NOT to use 36 spokes....

    I guarantee I can crush the end of a carbon steerer with a stem if it
    is not all the way thru..no problem.

  19. Hey, I'll donate my old fork if you mechanic types think you could prove
    something with it and post the results. Just the clamp area is bad and
    there's some steerer left to mangle with.

  20. Took a Salsa stem and the section of 1 1/8inch carbon steerer, no
    expander, ala Profile type forks, tightened booth bolts with the
    section 3mm below top and cracked the carbon. I took 4 fotos but they
    all came out fuzzy. I'll try to take them again, it was really no
    problem to crush the end of the section.
