And it's CARBON. Still mounts to the valve stem? :foo:

Pass.

I'll wait until I see real world accuracy numbers. I can't really see it working any better than the other terrible options for aerodynamic meters.

I will wait for DCRainmaker to weigh in on this one.

I have no idea how well it works, but I did say all along that the measurement method was about pressure changes due to rider effort in the tires. That seems to be confirmed now. What I don't get is how it is calibrated to rider and bike weight, etc.

I think potential users could save themselves $139 and 11g by simply recording their ride on their smartphone. The data won't be filled with as much noise.

FWIW rider weight doesn't change the pressure in the tire, but I doubt that it works much better now than it did in round 1. A disappointment for sure.

Hopped on my road bike this morning. My first thought was dang I wish this SRM was smaller...

Look at it this way, folks..At the very least, you'll have a really expensive(and unattractive) presta valve cap.

I just want a pressure meter that alerts when tire is dangerously low.

Can't it do that instead?
