    Let me know how the water sealing works.


    Power taps and wet haven't exactly worked well in the past. They claim to have fixed it but that remains to be seen.

    Saris can't build them fast enough. I work at American Classic, and we are building on them!! If you want a Disc Brake 2.4 Powertap we can build them 26" or 29", 32 hole only.
    LMN- the computer seal is VERY tight on these. We double check every PT we ship to ensure the seal is good. No problems so far for us!

    I ordered mine from my local shop: Geneva Bicycle Center, my guess is they called Saris and are able to get one? The shop is going to build it up to the hoop for me

    Saris has the hubs, just no rotors to go with them...I guess they've been selling extra rotors.

    No, I believe they have a custom bolt pattern.

    awwww she's luvly. We'll have to take them out for a ride together

    Was it plug and play for you or did you have to mess around with a few settings? How do you feel the power readings compare to your other PT's?

    Plug and Play.

    Plug and play, I set the time and aranged the display how I like it before I rode. But it worked right out of the box.
    I only have one ride on her but the data I downloaded was perfect. It seemed to have way less if any holes in the data.
    Oh, BTW thanks for the consult. (LWcoaching) A few things that I learned in that informative meeting have led to the best year yet (so far, knock on wood). Thanks.
    Enjoy The Ride!

    BN_A could you get me a Disc side photo of your wheel in the bike? A Similar angle to the one above, just from the other side.

    My PT Disk, with a 347g Stans 355 rim, 2.0/1.8 and 2.0/1.5 spokes 3x, Aluminum nips, Yellow tape, weighs 1030 without rotor. Add 160g for custom rotor, and also add for rotor bolts (x8).

    I did not get a chance to weigh the hub, but it looks like it should be very close to a standard PT SL (without rotor of course). You also need to add for the different axle, which I believe is steel.

    That seems dead on based on available info. Alum nips are ~10g per wheel, and the mix of spokes you have is ~165g per wheel. A few grams for the yellow tape, some subtraction, and I get 504g for hub only without rotor or rotor mounting hardware.

    Compared to Saris' web info quoting 680g less 160g for rotor as per Perry's post above, and maybe 15g for rotor bolts that gives 505g which is almost a dead match. Saris says the regular (i.e. road) PT 2.4 SL is 416g, so that means about 89g extra for all the extra material on the hub for the rotor mount, and any other changes they needed to maix it suitable for disc/MTB use.

    I bet most of that 89g is in the steel axle.
