Hey all,
Ergomo is out of stock except campi italian versions. Anyone know where I can get one?

I think all the Shimano ones were recalled. That might be why they are in short supply.

Hello
I have been away from the forum for a bit, and thought I should try to answer
some of the questions that have appeared. Copied below is a comparison of the powermeters on the market, they each have their strong points.
First the questions:
Left leg only:
As with any bb spindle power measurement, the data is left leg only. Most riders are somewhere in the 47/53 or better leg power ratio range, but some do have a signifigant discrepancy. The small discrepancy may not be worth correcting for, and for many riders it varies between legs. Larger discrepancy can be accounted for as the Ergomo has a calibration setting that can be raised or lowered to compensate. This is not the same as the free force value which is measured during installation by the system.
Dura Ace 10:
2004 Dura Ace 10 speed drivetrains and chains are compatible with 9 speed octalink based cranks. The 2004 7800 crank is not compatible with any bb other than the Shimano 7800. FSA cranks are available in octalink, and are 9/10 compatible.
Recall:
The recall only affected octalink, not square taper. The problem was overhardening of a spindle batch by the vendor. The entire batch was recalled, and the replacements were delayed as we took this opportunity to include a planned design upgrade to the octalink Ergomo. The new version octalink will be available late July, and customers awaiting their replacements should have received them by the end of July.
Ergomo/PT/SRM comparison:
The PT with standard rim has the advantage of being more affordable by several hundred dollars over the Ergomo, and about $1,500 over the SRM Pro. Also, with a PT wheel and a spare harness, a PT wheel can be easily passed around among a group of riders,a club, or used by a coach for athlete testing. The disadvantage is that unless you build with a race day rim, you usually have an everyday training weight rim on the PT, and you cannot use a disc.
With the Ergomo and the SRM, the ability to use any wheels at any time is a real advantage. This also makes it more likely that the rider will race with the powermeter, and racing provides excellent data. The SRM is an excellent product that has the longest history, while the Ergomo is more affordable and gives riders the added flexibility to swap crank lengths, or mount the new compact chainring cranks like FSA and Ritchey. Field reports indicate that the Ergomo is very weatherproof, and the Ergomo is not affected by ambient temperature changes. The Ergomo includes the Cycling Peaks software, licensed as ErgoRacer, called the “best available” in the powermeter review from VeloNews, Sept 8, 2003.
The accuracy of the PT, SRM and the Ergomo are all in the +/- 2% range.
The Polar is the most affordable of the available powermeters. There has been a wide range of experience and satisfaction reported among users, but when properly set-up and adjusted, coupled with better than average chain and drivetrain maintenance, it does work effectively.
