The hub readings I have seen from my old style pro and SL are all over the place. I don't know if the average reading over a period of time is correct or not.tomUK said:for those of you who've fitted the cadence sensor on the powertap - are the readings much different to those obtained from the hub? I'm wondering if it is worth installing this option.
Thanks
For me, the hub cadence is (amazingly) usually right. It has some noise in it, so jumps around a bit here and there, but it's usually right. It's close enough in my case that I can't imagine anyone wanting the wired cadence. However, it seems people vary on this, so it might depend on you/your bike/?tomUK said:for those of you who've fitted the cadence sensor on the powertap - are the readings much different to those obtained from the hub?

Here is a pic of a file using the hub (I hope). I doubt if I spent much (if any) time over 100 RPM on this ride - certainly nothing over 110. - TFlanierb said:For me, the hub cadence is (amazingly) usually right.

If you are a smooth pedaler the hub cadence readings will be wild. OTOH, if you mash your gears, the readings will improve. The hub seems to calculate cadence based on variance in power during a pedal stroke.tomUK said:for those of you who've fitted the cadence sensor on the powertap - are the readings much different to those obtained from the hub?

I have the same experience as NomadVW. Hub cadence for me isn't very accurate.NomadVW said:My cadence readings on the hub are all but useless.
1. The accuracy of hub-based cadence depends both on the rider and the situation.NomadVW said:My cadence readings on the hub are all but useless.
To "confirm" what Piotr said, my cadence evens out when I'm climbing hard.
Please expound on this comment. I'm very curious to hear how you've arrived at this conclusive statement. Personal experience, anecdotal evidence???RChung said:1. The accuracy of hub-based cadence depends both on the rider and the situation.
2. In general, even if cadence were accurate, it's pretty useless. Cadence is a red herring.
3. If you're really, truly, interested in cadence, it's often possible to recover the "true" cadence.
4. You shouldn't be really, truly, interested in doing that.
