    I recently moved to a 9sp frame(Klein Quantum) due to a cracked frame. I still use the front wheel
    from my 7sp frame and I bought an Matrix ISO 3 wheel for the back. I am currently doing alot of road
    work and I am training for a triathlon with a 56 mile time trial.

    I always have had backup wheels for my 7sp and I am looking to do the same for my new 9sp rear.
    But I am wanting some help on what is the best option for me. My front wheel is an ISOII that is
    10yrs old.

    I weight about 175 and am currently doing a 40k in about 1h05m.

    I have been seeing alot of these wheels like the R540s,or other type with bladed spokes. Is there
    really a great advantage in doing time trials with these. I was just going to find a used hub and
    have on old velocity rim that I was using on my 7sp, but I am considering buying a pair of those
    type wheels for time trialing but don't know if it is worth the expense. But considering the age of
    my front wheel, I am wondering if it may be a good idea to do it.

    Is my weight a consideration for any of those type wheels? or any particular to stay away from?

    Any suggestions would be helpful.

    can only say I actually like how it's designed. It is a very serviceable

    What kind of bearings does the Ultegra and lower use in their sealed


    cartridge

    models, what about Campy? I didn't have any paperwork with mine, is their a particular grease to
    use on it?

    I bought a used from a demo bike(low miles). I cleaned all the bearings

    We've gotten spoiled with the remove and replace cartridge BBs. Gasp! You actually have to maintain
    (!) a D/A BB??

    Phil Wood grease is an excellent grease to use for BB's. I wouldn't think another second on it!
