    I found this article to be deceptive and disingenuous. The author is trying to associate the manner in which carbon fails with increasing frequency and severity of accidents in pro racing. And...

    I have an old Trek which has little adjusters in the dropouts to help with this. I don't think there is anything sacrosanct that says you have to have the axle seated on both sides. If your QR...

    The basic physics are the same for both bicycles and motorcycles. (Stuff like weight, CG location, etc. are unimportant, at least in a basic theoretical sense. The equation for lean angle for any...

    Whether it was Sagan waiting on others or others waiting on Sagan, the result is the same - no one chased down Nibali. The point is that Sagan didn't have the luxury to wait around and see if someone...

    The green jersey competition is over, but Sagan finishing the tour with this jersey and no stage wins will be a huge disappointment to him and the team. The early stage in England where he didn't...

    Okay, taking your number at face value, would you be in favor a set of bicycle user fees which would pay for 40% of the cost of an expansion of dedicated bicycle infrastructure?

    The physics of 'throwing the bike" are that when the rider shifts his weight aft on the bike, the bike itself shifts forward to maintain the same CG.

    Whatever you decide is the right way to expand the bike infrastructure, someone has to pay for it. That's the 1000-lb gorilla in the room - governments are simply not going to dramatically up the...

    That's the problem with these discussions - they usually become inverted from "is this running a risk of a problem" to "prove that it will cause a problem". If your criteria for drilling into a...

    I wouldn't consider it. This is one of those things that, done properly, might be Okay, but you just don't start drilling holes in critical structures of a bicycle. It may also be darn hard to...

    The biology of this is tough.... to be a TDF-competitive sprinter requires huge muscle mass and brute strength and woman are at a big disadvantage here. A woman's smaller size could work in their...

    I agree with this. I've used three UN55's (maybe one was a UN54 - one had a plastic retainer on the non-drive side, but they're alum now as I recall) for tens of thousands of miles and have had no...

    If you select something with the proper threading, bottom bracket width, and spindle length you should be Okay. The fly in the ointment is that many older loose-balls/cups spindes are not symmetric...

    I'm not sure exactly why, but looks to me like it might be fairly early vintage, perhaps very early-80's. (My wife had a 1979 Trek and it reminds me of this bike.) And repainted/re-decaled. ...

    I can 2nd this.... when I did a recent rebuild of a bike with 1990-era Shimano bar-end shifters (7-speed), it took me a good 30 minutes to finally get the orientation correct so they'd index...

    Thanks, the bike gets ridden a couple times a week and is doing well. No changes since the rebuild. These old Treks are very nice bikes.

    Okay, maybe I should have said I have two Trek 400's, not two Trek 400 Elances. As I understand it, the Elance name came and went in the 80's.

    I have two 400 Elances, one is 531 and the other is TruTemper. Both very nice bikes. I'd inspect the Matrix rims carefully for cracks around the spoke holes.

    I agree with the previous. As long as you don't stray too far from the spec'ed dimensions you should be fine. But putting a 19-23mm tube in a 35mm tire is asking for trouble.
