Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

Yeah, it might be an idea.

I've bumped it up a bit more for the meanwhile.

Todays ride in the countryside with the Mrs: http://tpks.ws/41Dp

My bird fucked off to the beach so I went to Sigma Sport to dribble over some TT bike pr0n.

It was an EPIC ride full of EPICness.

Mine was full of Bluebells. And hills.

I went out past the Chilterns on Sunday and found green fields and rolling hills. Very picturesque but a pain in the butt with gear selection.

I'm finding 52/36 with an 11-25 is a nice range for the area just below London- North Downs and so on.

TT bike - front ring shifts are annoying. 55T all the way...

Anybody use quadrant analysis in Golden Cheetah, and have you made any improvements to your riding as a result? How exactly does it work other than telling you you were either pedaling with a lot of force, or pedaling quickly (or both, or neither), how can you benefit from this info other than pedaling harder/faster when training???

I've always ignored it, but I imagine it would be of use for steady state paced efforts like a TT- you could play around with gearing for the 10/25 miles and then see what your average power was against your HR say (I am aware that HR is deeply unfashionable, but it does give a general idea of how hard you are working).

i.e. 10 miles at 300 watts in 25 minutes is your baseline, do that at a cadence of 60 and then again the following week at a cadence of 90 and see what your PE/HR tell you?

Part of it is matching your training to the demands of your racing so if you looked at the plot of TT vs. a crit or a road race you'd see different patterns.

You can also look at individual performances and analyse why they were better or worse. How did you generate your best 20 min power? Pedalling faster or pedalling harder? What did your heart rate do?

^I really need to read my copy of TARWAPM

Confused now... Quadrant analysis shows average effective pedal force vs circumferential pedal velocity, no heart rate :-s

This.

Also have a look at training peaks website for more information.

Here's something I recently read that focuses on QA during Kona:

QA becomes a bit pointless if you are fixing your cadence, other than perhaps a confirmation but that's something your NP and average cadence would tell you.

Anyone got any clever ideas for LYC mounts?

The stock mounts don't seem up to British goat paths I ride on.

Maybe I could cut some holes in the top bit and zip tie it back on?

P2M - lots of talk on this thread of future purchasing, any one got one ? If so how they getting on with it ?

I believe that a couple of people have P2M meters now, I am consistantly tempted- I've got to the point of purchase a couple of times, only to back out given the only way to pay is bank transfer, which annoys the fuck out of me.

Dammit, Why P2M when you already have SRM?

Bank transfer?? They can fuck off. I think I'll get a quote to get it through my LBS if thats the case. I'm on the verge of getting one but still haven't sold my scull.

On which note however, does anyone have any experience of how the 310xt/910xt and Navi2Coach handles power data?

I currently have a 310xt but was going to get the P2M branded Navi because I read good reviews on DCrainmaker. However, I'm getting frustrated with not being able to record my pool swims and so now I'm contemplating spending a bit more and getting the 310 instead. My only worry with having everything in 1 computer is whether the 910 will be any good for recording/displaying power metrics with the P2M?

I have a 910xt, and do use it to record power data, however I don't use it during the ride- I only use it to record the data.

I guess that means you just have it on your wrist recording while you view your data the proper SRM head unit? Why this way round? I thought that the garmin only sampled a quarter of the SRM data to save battery power?

I download the SRM file into SRMWin, then export it to Training Peaks/WKO.

The data from the 910xt goes into Strava (for cycling), I upload running and swimming data direct from the Garmin into Training Peaks/WKO.

And yes, 910 on my wrist, PC7 on the bars.

Just checked, it's still bank transfer only on the P2M site.

Why is this such a issue ? Extra charges ?

I'd rather pay by credit card in order to have the protections afforded by that method.

As it stands direct bank transfer gives me the fear as it's totally without protection- like buying that Cinelli Laser via PayPal gift.

You do realise you can buy a P2M from an online shop in Germany that accepts card payments, don't you?
