Ergomo pro

stevevinck

Are here some users of the ergomo pro powermeter ?

experiences ? pros/contras

Woofer

Friend of mine uses it, loves it. Big CPU (SRM has the same issue, especially on most aerobars), early adopters got screwed - production problems but all got repaired under warranty, very inconvenient if you want to ride more than one bike, comes with cyclingpeaks software, installation requires a bit more technical expertise.

Squint

Do you have the dimensions of the SRM and Ergomo CPUs?

stevevinck

why should dimensions be an issue ?

What I'm trying to find out , does it function good , in every condition ? Can you rely on it ?


I don't like the fact that powertap goes in the rear wheel and because I often ride indoors (with other wheel with special indoor tire) that would be unusable for me

Ergomo only measures the torque and hence power from your left leg and then doubles the amount because it measures the twist of the bottom bracket. The SRM system and the Powertap system measure total torque throught the drive train from both legs and are therefore much better since most people develop quite different levels of power from each leg. Other than that the system is accurate.

I got a box in the basement from Ergomo. I'll go open it and measure the CPU.

It is ~7cm wide, ~8.5cm high and ~3cm thick(although this measurement varies greatly on how you measure it).

FWIW the viewing area is 5cm wide and 3.5cm high.

Hope this helps.

So Ovalmaster.... Let me get this straight.... You pedal better with one than with the other? If so then the rgomo would be a problem. There are a fair number of Pros using it out there. I guess your rebuttal would be that pros don't have uneven pedal strokes

I have one and I have a PT pro. they tell me my power is similar from both. Differences within drivetrain loss and accuracy variances. So either I'm just one of the few/ lucky people with an even pedal stroke or it's less of a problem than you might think. Oh the Ergomo pro is on my Scott CR1 and the Powertap Pro is is on my Colnago Master light.

I'm selling one PT Pro if anyone interested though And I'll put another ergomo BB in the Colnago with the proceeds.

Oh as for durability. One more thing. Hunter Allen used on on the La Ruta De Conquistadores Mtn. Bike race without so much as a hiccup. If it can survive through that water and mud soaked extravaganza it can take anything a mere mortal can throw at it.

The SRM PCV is 80 x 54 x 14 mm, also depending on where you measure it.

Did you measure the old or new Ergomo computer?

Meek One

My fault, I have an old model from last spring/summer NIB.

You asked for pros and cons. There are quite a few people who don't like the aesthetics of a really big CPU on their handlebars. You are not one of them but someone else reading this probably is.

Squint

Both the current SRM and Ergomo computers are smaller than their predecessors. Judging from pictures though, the new Ergomo computer seems disproportionately tall but it's not the monstrousity the previous computer was.

Woofer

Yes, the only person I know with one has the original godzilla model. Not very common around here either. One thing about that is if you have a powermeter that some other people around you might have, that makes it much easier to troubleshoot some types of problems. I see a lot of PowerTaps and some SRMs around the neighborhood.

I have a SRM V CPU and I really wish it was smaller and fit on my stem...

ovalmaster

I thought that most people had a right left power imbalance (legs and arms depending on how you are handed). Pros probably have less of an imbalance due to the training and milage that they do. I need to work on my imbalance which is quite significant (from tests) therefore the ergomo would be no use for me. Does anyone know if the SRM or power tap can show leg power imbalance similar to the Polar system.
