  1. Both are ISIS BB's. ISIS designs have come a long way, now most
    companies are switching to the outboard bearing design to take care of
    some of the old problems with ISIS...

    I know FSA's MegaExo has outboard ceramic bearings (??)..

    I was doing a side by side comparison of Token's Ti ISIS drive BB with
    Tiramic Bearings(http://www.tokenproducts.com/05htm/products.php?
    pc1id=46) and MegaEXO Ceramic BB..

    In the end both look sweet, but the Token BB is cheaper. Thought I'd
    ask someone here before making a decision. Technically, if you were to
    get either one of these, what would you choose and what would be the
    underlying reasons?

    Do Token BB's have outboard bearing design as well?

    Thx.

    Does not compute. You either need ISIS or you need external bearings
    for a two-piece crank. What kind of crank do you have? If you are
    buying a crank and BB, go with two-piece and avoid ISIS/Octalink.
    Avoid FSA. If you are stuck with ISIS, buy a durable and less
    expensive non-Ti BB because you will have to buy a lot of them and you
    shouldn't waste Ti. -- Jay Beattie.

    Let me clarify what I want exactly :

    Ceramic BB (ISIS) + a lightweight ISIS Crankset

    What I have now is an old shimano 9 speed dura ace (i bought it second
    hand) with octalink.

    I wanted to know the best product combo to go for, and cheapest
    option. I want to stay away from FSA but I'm not really sure why, and
    why other folks don't like them either. Any particular reason?
    Stronglight has a good reputation and that token BB looks sweeeet! The
    cassette also has CT2 ceramic teflon coating which must be cool to run
    with a titanium chain to minimize chainring wear. I'm not sure though.

    FSA on the other hand is popular in the pro peleton.. Give me a few
    reasons to hate them and save my pockets.

    The Ti in the BB is a coating on the race, not exactly a Ti axle or
    something. Maybe you should clarify what you meant in your last
    sentence.I didn't get you.

    I'd go with an outboard 2-piece (mega-exo), but I wouldn't do ceramic.
    Too much money for not enough benefit.

    The size of the ISIS spindle means smaller balls, and shorter bearing
    life. If you don't already have an ISIS setup, I wouldn't invest in
    it.

    My preference would be Campy Ultra-Torque. Coming soon in a Centaur
    Carbon model, if you want carbon. If not, Centaur or Veloce are both
    fine, available in full-size or compact. I have the Veloce CT-UT on my
    Guerciotti. Nice crank.

    Their products are flashy but not durable, at least based my
    experience with a broken wheel, BB and crank (and the experience of
    others on this NG). So, it sounds like you do not want ISIS but
    rather want Octalink -- which is a slightly more durable version of
    the oversized spline drive system. You can get any old Octalink v1 BB
    you like, but again, I would not waste my time with Ti due to the
    expense -- unless you find a BB with replaceable bearings. It's the
    bearings that fail because they are too small. I think RaceFace makes
    model with replaceable bearings, but I am not sure. -- Jay Beattie..

    So in other words, you're not advising me to go from octalink to ISIS
    due to durability issues? I thought in this age and time, ISIS would
    have improved its design over the past years.

    I got this from FSA's website.

    ISIS-Drive vs. Octalink

    ISIS-Drive BB's with 22mm diameter axles have superior strength and
    stiffness compared to Octalink BB's (also 22mm axles), which in turn
    were already an improvement over square-taper BB axles (17mm diameter
    axles). In our testing, ISIS-Drive BB's are typically at least
    20~30% stronger and stiffer than Octalink, for comparable BB's (i.e.
    we weren't using M12 DH ISIS-Drive BB's). Strength and stiffness of
    ISIS-Drive set the bar high in those categories. Going to the 24mm
    diameter axle used in integrated-BB's offers a marginal improvement,
    only a 9% diameter increase. In comparison, the 22mm axle is already
    29% larger diameter than the old benchmark 17mm axle.

    Currently, FSA ISIS-Drive BB bearing life is acceptable, although in
    the past, many ISIS-Drive BB's suffered from short bearing life. The
    same oversize axle that is great for strength and stiffness presented
    engineering and manufacturing challenges to fit bearings with a high
    enough load capacity inside the BB shell. (High-end Octalink BB's had
    similar problems.) The difficulty of engineering ISIS bearings can be
    evidenced by the fact that one of the 3 members of the ISIS-Drive
    Committee never produced an ISIS-Drive BB, while another member was
    the first to follow with an external bearing BB.

    FSA has used it's bearing know-how to develop long-lasting ISIS-Drive
    bearing BB's. Last year, CSC was on ISIS-Drive with good results
    (ridden to 3 stage wins in the Tour de France)! We have taken the
    feedback from CSC and have continued to improve our ISIS-Drive BB's by
    introducing high-end quadruple bearing versions with improved sealing,
    under the designation "MegaQuad".

    You are right, mega exo is not ISIS and is 2 piece. But I'm not sure
    why people seem to think the new ISIS compares badly with Octalink.
    Token BB seems like a great BB. Here's the spec sheet I obtained from

    Who said it compares badly with Octalink? I think the conventional
    wisdom here is that they're equally flawed. Oversized spindle + fixed
    shell diameter = small bearings. Only way to get around that and keep
    the larger spindle is to increase the shell size, which they
    accomplish by moving the bearings outside of the shell.

    And a spec sheet isn't going to point out a standard's weaknesses.

    Yes I want to change my crankset/BB system totally from what I have
    now.

    It comes down to ISIS vs MegaExo.

    They have been saying ISIS has improved their designs over the years
    since they had bearing issues.
    On the other hand, I pick up a lot of conflicting stories about BB

    I would think that FSA's megaExo is a better design from what you have
    pointed out.

    That leaves me with one question. I know FSA's races are made of
    hardened tool steel. The spec page for Token's ISIS BB claims it
    features proprietary Titanium coated bearing races and cones. What is
    the advantage of doing this and does this fare any better when
    compared to what FSA has?

    You are right, mega exo is not ISIS and is 2 piece. But I'm not sure
    why people seem to think the new ISIS compares badly with Octalink.

    Quoted message said:

    Who said it compares badly with Octalink? I think the conventional
    wisdom here is that they're equally flawed. Oversized spindle + fixed
    shell diameter = small bearings. Only way to get around that and keep
    the larger spindle is to increase the shell size, which they
    accomplish by moving the bearings outside of the shell.

    And a spec sheet isn't going to point out a standard's weaknesses.

    They have been saying ISIS has improved their designs over the years
    since they had bearing issues.

    I wouldn't think any coating would be preferable as with the forces
    involved I would not be surprised to hear of the different materials
    separating, further a tool steel race would smoothen and harden with
    use

    Both are ISIS BB's. ISIS designs have come a long way, now most
    companies are switching to the outboard bearing design to take care of
    some of the old problems with ISIS...
    I know FSA's MegaExo has outboard ceramic bearings (??)..
    I was doing a side by side comparison of Token's Ti ISIS drive BB with
    Tiramic Bearings(http://www.tokenproducts.com/05htm/products.php?
    pc1id=46) and MegaEXO Ceramic BB..
    In the end both look sweet, but the Token BB is cheaper. Thought I'd
    ask someone here before making a decision. Technically, if you were to
    get either one of these, what would you choose and what would be the
    underlying reasons?
    Do Token BB's have outboard bearing design as well?

    I'd go with an outboard 2-piece (mega-exo), but I wouldn't do ceramic.
    Too much money for not enough benefit.
    The size of the ISIS spindle means smaller balls, and shorter bearing
    life. If you don't already have an ISIS setup, I wouldn't invest in
    it.
    My preference would be Campy Ultra-Torque. Coming soon in a Centaur
    Carbon model, if you want carbon. If not, Centaur or Veloce are both
    fine, available in full-size or compact. I have the Veloce CT-UT on my
    Guerciotti. Nice crank.

    But the MegaEXO bb is advertised to have oversized bearings.

    woo hoo.
    oversized bearings, eh?

    Let me clarify what I want exactly :
    Ceramic BB (ISIS) + a lightweight ISIS Crankset
    What I have now is an old shimano 9 speed dura ace (i bought it second
    hand) with octalink.
    I wanted to know the best product combo to go for, and cheapest
    option. I want to stay away from FSA but I'm not really sure why, and
    why other folks don't like them either. Any particular reason?
    Stronglight has a good reputation and that token BB looks sweeeet! The
    cassette also has CT2 ceramic teflon coating which must be cool to run
    with a titanium chain to minimize chainring wear. I'm not sure though.
    FSA on the other hand is popular in the pro peleton.. Give me a few

    Their products are flashy but not durable, at least based my

    the oversized spline drive system. You can get any old Octalink v1 BB
    you like, but again, I would not waste my time with Ti due to the

    I got this from FSA's website.
    ISIS-Drive vs. Octalink
    ISIS-Drive BB's with 22mm diameter axles have superior strength and
    stiffness compared to Octalink BB's (also 22mm axles), which in turn
    were already an improvement over square-taper BB axles (17mm diameter
    axles). In our testing, ISIS-Drive BB's are typically at least
    20~30% stronger and stiffer than Octalink, for comparable BB's (i.e.
    we weren't using M12 DH ISIS-Drive BB's). Strength and stiffness of
    ISIS-Drive set the bar high in those categories. Going to the 24mm
    diameter axle used in integrated-BB's offers a marginal improvement,
    only a 9% diameter increase. In comparison, the 22mm axle is already
    29% larger diameter than the old benchmark 17mm axle.

    Currently, FSA ISIS-Drive BB bearing life is acceptable, although in
    the past, many ISIS-Drive BB's suffered from short bearing life. The
    same oversize axle that is great for strength and stiffness presented
    engineering and manufacturing challenges to fit bearings with a high
    enough load capacity inside the BB shell. (High-end Octalink BB's had
    similar problems.) The difficulty of engineering ISIS bearings can be
    evidenced by the fact that one of the 3 members of the ISIS-Drive
    Committee never produced an ISIS-Drive BB, while another member was
    the first to follow with an external bearing BB.

    FSA has used it's bearing know-how to develop long-lasting ISIS-Drive
    bearing BB's. Last year, CSC was on ISIS-Drive with good results
    (ridden to 3 stage wins in the Tour de France)! We have taken the
    feedback from CSC and have continued to improve our ISIS-Drive BB's by
    introducing high-end quadruple bearing versions with improved sealing,
    under the designation "MegaQuad".

    Great research, congratulations. You've clearly discredited the riders
    who actually bought one, actually trashed it, actually replaced it after
    failure with a more durable design.

    quadruple. oversize, ceramic, seal, whatever. My daily bike's crank
    bearing runs fine on its fourth rebuild since 1972. It was used when I
    bought it. See you in about 35 years = we'll compare bearing wear.

    What poppycock. This implies that square taper was somehow weak and
    flexy..both of which is not true. Larger spindle outside diameter is
    only larger, not better. Both resulted in small bearings, that
    resulted is toasted BBs..enter the outboard bearing crank..a 'fix' for
    ISIS and Octalink..NOT square taper. Octalink was meant to be market-
    ed against square taper, ISIS vs Octalink...once again, enter outboard
    bearings...Next step is this ceramic BS...for a 60-100 rpm system,
    needs ceramic?
