Zip ties on your cranks are SO un-ELITE

No problem! I should re-word slightly to say “(measured with good old magnets)”. Transmission is wireless.

Tip for crank mounted magnets: you can use a ring shaped rare earth magnet on the inside of your pedal spindle instead of zip tie-ing the included magnet to your crank. It might be slightly heavier but is well worth it imo.

small disk magnets the size of the back of the pedal spindle work too. Less weight than the stock one for the weight wee-kneez to boot. That said I am too lazy to upgrade and still have the stock one with a stainless wire holding it in place. OMG So un-elite.

I like to use the Garmin usb dongle in the laptop. Run Traineroad and Netflix at the same time to cut into the mind and butt numbing aspects of riding the mouse wheel.

A powertap will measure cadence without the need for anything on the cranks!

The PowerTap cadence is based on spikes in your power though (I think?), so in theory if you have a perfectly smooth stroke it won’t measure properly.

Yeah I use the ring shape because it’s easier to remove. I have Crank Bros pedals which use a hex in the back of the pedal spindle, so I’d occasionally want to remove the magnet. If your pedals use a normal pedal wrench there’s probably no need for the ring shape.

I had a zip tie for some time but it was prone to moving around every now and then, and you also get occasional rubbing when you ride. Also: Not aero.

Quarq and SRMs have the magnet mounted to a BB cup or BB guide. cant see the magnet at all.

I do notice that my powertaps read cadence lower than my quarq, fwiw.

PTs use science to estimate the cadence, so you’ll see some crazy fluctuations here and there (like 250rpm spikes) but they are generally pretty consistent, which is the important part.

This is what I do. I haven’t found it to be a problem with removing pedals with a hex wrench; they pop off easily with a tool — though you do have to be careful not to lose the magnet. I could see ring being a little more convenient if they’re easy to find (?)

The disc magnets can be found on ebay easily; search for “Icarus crank magnet”. I imagine there are cheaper ways to get them.

Yeah I think we’re all talking about the same location. By inside spindle I mean back of spindle, or whatever.

These worked for me. Just keep them away from kids (maybe). Probably cheaper on ebay, etc.
