    Default What kind of powertap do I have?

    I bought a P2owertap recently and the seller sold it as a Powertap SL 2.4 (thus implying it can be upgraded to ANT+ spec). I have a feeling it in fact is a wired Powertap SL model. Can you tell this from the photos?







    Thanks!

    The rear of the CPU has the following numbers:
    IC: 6459A-SL2P401.
    FCC ID: T8P-SL2P401

    This seems to mean that the head unit at least is 2.4 wireless compatible. But what about the hub?

    It looks like a wireless model but not a Ant+ version. You can use them with the wireless Joule head but not with Ant+ compatible head units.

    I believe Ant+ units are called SL+.

    there's an updater to make the hub compatable with ant+ that you can order from saris... i think it's like $50..

    Looks like the older 12mm axle generation.

    "Comp" was wired with a steel axle and freehub body
    "SL" was wired with an aluminum axle and freehub body
    "2.4" was wireless but not ANT+
    "2.4+" was the 2.4 with the ANT+ firmware update
    "SL+" was ANT+ out of the box
    "SLC+" was the SL+ with ceramic bearings

    Trouble is that the battery covers are interchangeable and may not be original.

    A wired hub will not talk to a wireless head unit, even through the wiring harness.
    A wireless hub will only talk to a "like" wireless headunit. (ANT<>ANT, ANT+<>ANT+).

    Well I did what I should have done earlier and called CycleOps. It turns out the hub is exactly what it appears, a Powertap SL wired. I don't have much use for it now since I need something that connects to my Garmin but I'll see about trading it/returning it. Thanks all.
