Cadence........ do you use a sensor or not

Do you guys find cadence information from a computer necessary in your training or do you "spot check" and or just been riding for so long that you can feel what cadence range you are doing while riding?


Discussion between me and another person is that accurate cadence data is a must for your training/TT racing where I feel that using feel and or near accurate PT hub cadence is more than enough. To be honest I never look at cadence unless im doing a drill that requires a certain range and then I only spot check.

Not that theres a right or wrong way but wondering what you guys/gals do.

When I first started seriously training I paid attention to cadence, but not anymore.

I still record it, though, as I can't remove the cadence sensor from my Ergomo.

I don't have a sensor but I still monitor my cadence. The powertap does it through the hub somehow. I don't need to know the details, it just does it.

I find myself riding to low of a cadence from time to time so I having it display does help me keep it a bit higher.

I still note it after races. Seems like I train around 87rpm and race around 96rpm. Works for me.

i've got a flitedeck on my tcr, and have found the virtual cadence pretty helpful at times.

i tend to look at it the most when i'm in a break.

for some inexplicable reason, i pay more attention to my cadence than to the actual speed.

i use cadence a lot in training mainly because my coach has me doing lots of drills to try and raise my cadence. I rarely look at anything other than power or hr otherwise.

For the PT guys do you find the cadence data with the hub sensor good enough or do you run the extra sensor too?

Yeah, the curve with the PT isn't so smooth with the hub data, but the 5s averages and above seem fine. It's funny though, once you have Watts, you really stop caring as much about the other stuff Speed? HR? Cadence? meh

Step 1: Disconnect the sensor.
Step 2: Pedal.
Step 3: Profit?

I stopped wearing my HR strap a week ago with the same thought.

I stopped using the cadence sensor altogether on the PT. I don't display it at all. I'll look at what the hub records, but the hub can be wildly inaccurate at times. Since the hub generates cadence based on differences in torque, the smoother you pedal, the more inaccurate it can be (or so I've read somewhere at some time).

Re: HR monitor, and minor thread hijack. I still use it for threshold workouts (20 min or longer) but I only compare the data to other workouts on similar conditions (eg mostly same fatigue level)

Cadence with power has helped my sprint. I went from grinding it out at 120 rpm to spinning at 150 rpm and my 5s power improved over 10%. 10s went up around 8%.

sounds about right.

off the top of y head, i can only recall 3 occasions over the past 3 years where i was working solely off of my HRM, and those all involved climbing/surviving passo giau.

I used it when I started riding to get a baseline for a good cadence. Since then, not so much, especially since I now have a PM, which like others have said, after you get that, you don't really look at anything else. Though some workouts I have to as my coach still trains me with it as she hasn't yet adopted power.

a few times... i noticed my cadence while racing is typically higher than when training. so, it helped to train a bit more at race cadences.

Sounds about right. Although I only do any drills where I have a specific cadence in the winter. I do look at it while I am warming up on occasion, in particular on the trainer.

When I first hop on my trainer it feels really awkward (likely due to the lack of momentum to carry me through the top of a pedal stroke). I do a few spin ups during my warm up where I take it up to 130 rpms or so for 30 seconds. After doing that I feel smooth at my usual 95-105 rpms.

The PT hub cadence is completely useless for me. The only time it's correct is when I am stomping on the pedals. The rest of the time it reads very high. I'd like to think that it's my smooth pedal stroke developed from years of riding, but it's more likely due to my lack of power.

damn, your "grinding" is my spinning. haha.

you do know that the little lever on the right shifts up right? 150rpm in the 53x12 is over 50mph.

that's for his sprint, so it's going to be a higher cadence anyway.

I've got it but don't really use it. I'd be quite open to suggestions regarding how to incorporate it into training though.

I have a sensor but to be honest I don't look at it anymore. I know when it feels right and that "right" feeling is a moving target. It changes for me depending on many factors such as fatigue, weather and my mental outlook...
