    The current Park tools just have the 22mm thread, which is Campy, Shimano, and nearly every other commonly encountered crankset with threaded arms.

    The old Park tool had 22mm on one side, and 23mm on the other for TA cranks. ;-)

    Lol... guess there's no need for suspension in Florida. If all the trails are like that there, go hardtail. Lighter and more efficient.

    The trails are not all like that. Below is another trail in the same park, and like the others, it's much worse in person than it appears on the video. The one time I rode these Red trails, I took such a hammering that I'll probably never go on them again, even with a FS bike. :nah

    That's how I remember it, but couldn't comment on the current item.

    Note to Gummee and anyone else who runs into this: Stronglight cranks are yet a different size and if you try to use the TA puller YOU WILL DESTROY THE THREADS. Stronglight are 23.35mm, just to piss us off.

    SheldonBrown.com is saying 23.35mm is pre-1982....

    Y'all have never seen Ricky's setup have y'all?

    in the 'what makes you smile category:' I was on my way to the ride last nite and realized that the socks I was wearing were the same age as the car I was driving.

    Both are darn near old enough to vote!

    Ricky who?

    Hell, I've got socks older than most of the people I ride with. One pair was purchased back in 1981. :eek1

    So if I've gotta carbon fiber road bike and find a couple spots where the top-layer of finish has been scratched away (thereby exposing the fiber to the atmosphere), should I cover the spot with something? lacquer? clear fingernail polish? snot?

    Don't care how it looks - just didn't know if there's some weird quirk about carbon fiber turning to jello if it's exposed to the atmosphere or something? :dunno

    I recall being told that exposure to UV light and air is damaging to CF. The CF parts on my '96 Ducati were covered with a thin layer of clearcoat so as to showcase the fiber weave everyone seems to love, but after a few years you could clearly see evidence of sun bleaching. Eventually cracks started to form at the edges, and the parts had to be replaced. I've noticed that on my new bicycles, all the CF is covered in opaque paint, not just clearcoat. I assume this is being done to protect the CF against the damage from UV light. Painting your entire frame in some opaque color might be cost prohibitive, but I would at least put clearcoat back on the exposed portions you mention.

    Are you talking about the guy from Colombia? If so, I do know who he is. I purchased one of his custom made handlebars for my 1150GS years ago.

    The clear coat can have anti-UV stuff added so it doesn't hurt things.

    You want to keep it sealed from moisture.
    Banging it enough to crack off the topcoat and expose fibre is a bad thing. The fibers are not happy to be whacked at.I think I'd use some fiberglass repair epoxy. Check the radio control forums/web for stuff. They use a lot of the stuff, or just ask the LBS.

    Guys,

    Thanks for all the info about crank arm removal, etc. I managed to pull my crank arms last night. I also took the chain rings apart and gave everything a good cleaning. Everything seemed to go back together OK. I also pulled my cassette off the rear wheel and cleaned everything back there. My cassette actually went from black to silver! The bike looks brand-new. Quick question. The cassette lock ring was hand-tight. That's not right, right?

    Next up, chain replacement. I've done a few motorcycle chains and I have a motorcycle chain break and rivet tool. Will that work on a bicycle chain?
