funny this came up. i'm researching power meters for a new bike i'm planning to buy. i'm leaning towards the ergomo right now. $1600 or so, from what i'm seeing. supposedly it's quite accurate. it mounts in the BB, so it's supposed to be really protected from the elements. advantages - you can swap from training to racing wheels and still have it providing power on your bike, it can handle multiple files (unlike the stupid powercrap), it's only 100 grams heavier than a dura-ace BB, and the battery is rechargeable. i'm leary of it because it doesn't use strain gauges; it's an optical read of the torque in the BB, so all it can sense is the power generated by your left leg. it simply assumes the right is putting out the same kind of numbers. this is fine if you have a pretty even power output throughout your cadence. it's gonna be off if one leg is stronger than the other. that said, i've read where having a 5% difference in leg strength means less than a 10 watt difference in power output, so maybe it's not a big deal. since it stays on the bike and allows you to put any and all wheels on it, and it's half the cost of the SRM, i'm thinking hard about giving the ergomo a shot. check with vino. he has one
