    Pulled a bit of overtime today which was not a chore, the other guy on
    is the guy who's pulled me in to ATB. He had much more to do than I did
    so I left him to it.

    So he has a bit of a break and we chew fat a bit about the upcoming
    ATB. He's got a Bad Boy (which I really like) and he took me through
    things like his disc brakes which are a bit of a mystery to me etc.

    Then we got to looking at my bike. ``Gee, it really is a commuter isn't
    it?'' he says. Lets see, NiteFlux, rack, frame pump; yup.

    He looks a bit closer. ``Mate, your rims are shot.''

    Now I've heard about rims going but it's not something I've experienced
    to date. Pictures were painted for me of rim exploding while going
    downhill at 70+km/h. I didn't need much persuading to visit BSC tout
    suite.

    Talked to Sean(spelling?) and he put it too me that with 40,000kms
    behind them I'd be better off getting new wheels rather than new rims
    for the old hubs. After pointing out that I normally have around about
    15kgs of luggage on the racks (only when I'm on call thank goodness, one
    week in three) and he steered me towards a set of Ritchley Aero OCR
    rims built on to Dice hubs with DT spokes. Five twenty knocked down to
    four forty. Eek! Oh well, it is my transport.

    Went down the road for caffeine and cake while waiting; friendly barista
    so chatted to him a bit and mentioned I'm doing ATB. Turns out he lives
    in Geelong. Two hundred and forty five a week in fuel! Fsck, that put
    things in perspective!

    Picked up bike a little grumpy about having spent money (I am Scottish.)

    Grumpiness lasted till halfway down Hotham Street. These new wheels are
    NICE! Very NICE! They seem to handle bumps in the road better, they're
    smooth as silk and I do believe they actually go faster! Maybe it's a
    tailwind, so I turned round and did five ks in the other direction.
    Nope, definately faster!

    I rode home grinning from ear to ear, I even went ``Wheeeeeeeeee!'' on
    occaision which drew some odd looks from pedestrians waiting to cross
    the road.

    What next to replace I wonder (oh no, more money! But it feels so
    Good!)

    It depends on how they've been looked after, what quality they are, and
    the alignment of the planets. Given your further comment that you're a
    tight git^W^WScot, I'm assuming you at least kept the hubs to build up
    into a new set of rims. A regrease, possibly new bearings, and there's no
    reason they shouldn't be good for a few thousand more ks.

    And a 2nd set of wheels can be a nice thing to have anyway

    Aha! We now know the true story: you wanted new wheels! A true Scot would have bought rims with the same effective rim diameter and number of holes, taped it next to the existing wheel and then transferred the spokes one at a time... Servicing the hub was a red herring that was (cunningly) thrown in to help justify the purchase of entirely new wheels!

    Well played sir!

    Keep an eye on the rear OCR rim. They have a reputation for cracking around
    the spoke holes. I had it happen on two of those rims, and the bike shop
    told me that they were prone to cracking.

    spokes one at a time...

    That's what I did a few weeks ago. Mavic Open Pro rim (not CD) with a
    couple of broken ferrules and a few cracks around spoke holes. Back
    wheel. Just under 25,000 kms. The big problem, I think, (apart from my
    weight - we won't mention that :-)) was over tensioning the spokes. I
    originally got the wheels built with DT Competition black spokes. Very
    smart, but they get out of true. The natural reaction, for me at
    least, when the wheel went out of true was to think that some spokes
    had become a bit loose and to tighten them to bring the wheel back
    into true. Big mistake.

    Rebuilding the wheel was easy. I already had Jobst Brandt's book and
    Sheldon Brown's instructions are clear and concise. I bought myself a
    Minoura truing stand. I'd been planning to build a wheel or three for
    some time.

    I was paranoid about over tensioning, so took longer than I needed and
    checked the tension (plink, plink) against professionally built
    wheels. After about 300 kms, it's still true visually. I'll be putting
    it on the truing stand for a 500 km free service soon :-)

    So don't be frightened about building (or rebuilding) your own wheels.
    It just takes patience and a few tools. And you get a good feeling of
    accomplishment when you can look at the wheel and think "I built
    that". Of course, your first reaction is probably going to be one of
    total shock: "Good grief, would you look at that. It's round!" :-)
