    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.

    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!
