  1. After torquing to 25-lb-ft, I notice the axle doesn't turn as quite as easy
    as before it was installed. Is this possibly a slight distortion in the BB
    shell, or more likely the Phil cups grabbing onto the bb housing not
    completely perfect? I kind of doubt a brand new Colnago C50 has a
    mis-aligned shell. Anyone notice this, and if so, does the BB spindle
    loosen up? It's not MUCH different than before, just a little. I do
    realize sealed bearings when new, have more "stiction" than roller bearings.

  2. First, do you see any dissonnance in your choice of BB and frame?
    The Phil Wood BB is, albiet one of the best BB's, a very heavy piece to
    be installing on a superlight frame like the Colnago C50.

    To answer your question though, this slight level of increased
    resistance is common with an installed Phil BB and is not noticeable
    once you are actually on the bike. Also you are making a bad assumption
    in assuming that the BB shell on the new colnago is perfect. things can
    get through the cranks anywhere, and are actually more common in hand
    processes.

  3. Well the C50 is NOT super light at all. There are many carbon framesets far
    lighter than the C50. That's the main reason I bought it; It's a VERY
    robust frame. But what you say here. ."slight level of increased resistance
    is common with an installed Phil BB and is not noticeableonce you are
    actually on the bike. . ." Is what I'm experiencing. If you turn the
    spindle with the cranks on you don't notice it. Only when hand turning the
    spindle.

    Huh? I recently purchased a used Phil Wood mag-ti bb, its super light at
    around 150g. How many bbs are that much lighter (and I should say as
    strong)?

    If it's Ti, it's not strong. The spindles break off.

    Phil BBs start a bit stiff, and that may be what you are feeling.
    When installed, the feel is slightly more stiff, but I think this
    is an illusion and results from the fact that the unit is
    installed in the BB shell and not being spun in hand. If the unit
    feels appreciably more stiff, then you have overtightened the
    rings, which is unlikely at 25 foot pounds.

    I may get flamed for this, but I believe that it is possible to
    mis-install a Phil BB. This occurs when the shoulders of the
    unit do not seat into the retaining rings but rather hang up (the
    rings are tight), which causes the unit to go in slightly
    cross-wise. This causes the bearings to bind when the retaining
    rings are brought up to torque. When the unit finally seats, it
    gets loose, and the cranks rock. Whether this is lore or not, I
    believe it happened to me. What I did was uninstall the unit;
    put a small amount of Phil grease on the outer shoulder (not on
    the rings, of course, which get Locktite); reinstall the unit,
    making sure it was going directly and smoothly into the rings;
    then I brought it up to torque and checked to see if it was
    binding. It was not. If your C50 has an Italian BB shell, I
    would be very diligent with the Locktite (clean the shell and the
    rings with a good degreaser that leaves no residue) because
    Italian BBs are prone to loosening. If in doubt, call Phil. --

    That was my first reaction, especially since I weigh in the 190+lb catagory.
    However, before I bought the bb, I emailed Phil and they told me "no
    problem., our ti spindles are fine for riders up to 250lbs!" I'm saving the
    email....

    Phils are sensitive to BB threads out of plane. See if the
    Campagnolo thread guides pass easily with fingers only. If
    not, retap the BB with a Campagnolo or similar piloted tap
    set, so both sides of the shell are cut on one axis.

    Why would a 200 lb. man risk major falls and broken bones for 2 oz. I
    can take 2 oz less water or empty pockets of 2 oz of stuff.

    Superlight, interesting choice of words on this overpriced, made like a
    $1500 Calfee Luna, frame.

    I agree about the BB shell not being perfect tho. Colnago's QC, nor
    their warranty department are not something to yell about.

    A little seal drag is possible with the Phil BB BUT run a tap thru the
    threads of the C-50. Assuming that Colnago BB threads, along with other
    things about the frame being perfect because it's so expensive is not
    quite accurate.

  12. No flames at all, in fact I said the very thing on a "Roadbike Review"
    form thread. The cups have all those edges that "catch" the BB
    housing. I can see easily how if two or three cought before the others
    it may ever so slightly change the axial alignment. The spindle turns
    smooth still, it just seems to be a little stiffer than before. Also,
    the Phil seems to have VERY tight specs, I imagine if I stuck a
    Campgnolo BB in the same hole it would not exhibit this odd behavior.

    I'm with Paul.

    After seeing perfectly innocent humans with smashed faces
    hips, hands and bicycles, we no longer sell _any_ titanium
    spindles here- BB or pedal. Phil's quality is nonpareil -
    I'm sure it's among the every best - but titanium just isn't
    reliable in the application.

    I fully agree with you on that. I guess what I should have said it's
    essentially impossible to mess up tapping an Italian Bottom Bracket,
    and that's why Colnago and Tesh (I imagine others) use this type of
    threading. You align on ONE side, and just go straight through. I
    should have said that. I'm 99.9% positive it's the Phil BB, and I've
    heard others say the same thing. It seems best installation is loctite
    242 and minimal touque on locking rings. The interference fit between
    the rings and the housing is overkill IMO.

    OK I understand you.

    But the frequency of Phil Wood problems is quite small and
    thread issues with Colnagos are common. In practice, few
    houses pass one tap all the way through.

    Tesch at least had a fixture on his lathe he would use to hold the BB
    while cutting threads all the way through with the lathe.

    Since all of the BB taps I've ever seen were only about as long as
    they were wide, they really can't be expected to pilot themselves
    perfectly thru a bottom bracket. They will wander.

    The only way to prevent this is to use piloted taps from each side.
