Ergomo Install

That was easy! It slipped in and worked with no finagling around for hours. Not quite plug and play but no headaches involved. It comes with instructions written for a gal with my level of mechanical knowledge i.e. it actually told me which was the left and right side of the bike! It also comes with a few tools needed for the job to thread in the bb without ripping off the sensor cables. The only things I needed were a torque wrench and a 34mm socket. The socket required a trip to the hardware store. I had a torque wrench.

The Ergomo is inside the bottom bracket so step one was to take off my old cranks and bb and clean out the shell. Now I know what I'm doing that only took 5 minutes.

Next thread the Ergomo bb into the shell. On the left side are two sensor cables which must be oriented at 9pm with the bb tightened to 55 Nm. On my first try it was at 6pm. Add a few washers until it ends up at 9pm. I ended up with 3 washers which meant I had to put the bb in and out a few times to get it right.

Bolt on the cranks

Tape up the two sensor cables. One goes to the rear wheel to pick up speed and the other from the bb to the cpu. The speed sensor worked first time too. I thought I may have to do something tricky with it but no...

Enter wheel circumference, K-Factor and check the offset. Go ride.

Lookie here I have watts, heart rate, cadence, speed and time!

The whole system is really contained. There are not a lot of wires and pieces to get ripped off-road. I'm pretty psyched on this right now. Tomorrow I'll take it off road. The forecast is windy with a high of 41F - brrr...

Looks good....

looks like a very clean setup!

Did you grease your bb? and the splines?

Awesome. That's a lotta numbers staring you in the face.

How's the chainline? Any troubles with the front d action?

Should be fun/interesting to see how live IF/Pnorm/TSS readings are implemented into your training. A whole new frontier.

Now you know you're gonna have to put a PT wheel on for some file comparison action. It's the only way to know if the ergomo's function matches it's asthetics.

Rear brakes? They're overrated anyway.

Yup, I greased up. The red stuff from Rock 'n Roll goes everywhere. Thanks for the tip. I need lots of them. I'm getting a ton better at this mechanical stuff as I do it more. I've got a couple of great local guys willing to lend me tools and help me over the speed bumps (thanks Andy and Kong!). I haven't trashed or stripped anything yet.

Chainline and front d are good but I've got some testing in the dirt to do. So far it's just been up and down the street. The feeling in my legs pedaling up the street is the Ergomo power is spot on compared to both of my PT's.

I'm off to do a regular loop I have lots of time, HR and power data for so it will be a good first outing comp. I'll post the file later maybe.

This Ergomo has altitude on so it'll be fun to see acumulated elevations too.

Oh lala. Very exciting. Can you take photos of the wiring up the bike?

Great page.

Was that the handlebar mount the Ergomo Pro came with? I just installed mine and it's a bit different. It puts the computer square on top of the bars, while your puts is in front.

I much prefer yours. If it's not standard from Ergomo, where did you get it?
