    Ah, that explains some of it then. I pulled the GP4000sII numbers off of bikestiredirects page. They just list 330 TPI, but it would make sense if it was 3x110.

    Main tire factors:
    1) Rolling resistance
    2) Traction
    3) Suppleness/flexibility
    4) Flat protection
    Other stuff-- Weight, mounting difficulty

    Thoughts on a road tubeless conversion. I know Boyd mentioned it worked with a Stan's kit. My main concern would be corrosion, aka the Shimano problem.

    People here are under the impression that a partially worn tire is more prone to flatting.

    In my experience, flatting seems to be a function of what I ran over. Brand new tire, old tire, front,...

    Honestly, the best way to tell is go to a shop demo day, and demo a bike with better components. That's the only way to tell if you'll notice a difference. Everyone rides a bike differently, some...

    One major thing I noticed. The top tier components use better components for adjusters. Phillips head screws (prone to stripping) are replaced by metric allen bolts. Things like that. Brake...

    This.

    Mt. Washington is an extreme example. You're going to need to invest some money and time getting a dedicated gearing setup for such a climb.

    Hill repeats are good, but you probably...

    New on front makes sense depending on how fast you wear your front down. Depending on annual mileage, its entirely possible to have the front tire dry out before wearing out. If you normally...

    In theory I like the new front, old back approach. The problem is that you either have A) mis-matched tires or B) can never change tire brand.

    I just did a front/back swap. I wore the rear...

    With a proper spline design and tolerancing it should work fine until it suddenly falls off. The advantage of spline type is that the crank is basically locked into place by the splines. The should...

    Yike! What all needs to be fixed? At that price I'd considered the frame toasted and just get a new one. Frequently the difference between mid vs high-end frame is mainly going to be weight. So...

    As you go up, shifts are lighter and faster. The lever pressure and travel required to shift goes down, and the shift speed goes up. The difference is...

    You can probably just swap to a 12-30 cassette easily. That will help. That (12%) is still one hell of a hill. I run a standard 34-28 combination and that good for extended climbs up to about 8%...

    The negative drag is real. What's happening is the wheel is turning into a wing/sail. Remember that scenario only occurs with strong cross-winds, such that you can get a 30 mph wind at 20deg yaw...

    Thanks for the feedback, that's exactly the sort of info I was interested in. I'm assuming the rims stiffness (due to depth) results in just a slightly harsher ride?

    Considering new wheels (carbon vs Al)

    So I've been kicking around the idea of new wheels.

    The main things I'm considering:
    Boyd Altamonts
    Cheap Carbon Clinchers (38-50mm deep, high Tg >200C)
    Something from Psimet

    I'm currently...

    I think you're getting the Pro-Form trainer confused with the LeMond Revolution trainer (which is very good, but loud). I couldn't find the review you're talking about.

    I really wish there was torque spec on Sidi shoes, because you definitely want those bolts properly tight.

    The issue is corrosion of the aluminum rims due to the ammonia in Stan's. The C24 carbon rim won't have that issue, since its a carbon rim.
