TS and 500 like her last run I'm thinking?

Rotor
 

Team Sprint for sure. She's taller and wider than the other ladies, so I'm sure she provides great shelter as "Man 1".

Maybe 500 for World Cup and World Championships, but there isn't a 500 in the Olympics.

Keirin maybe? I mean, she's probably got killer bike handling skills from BMX and Jamie Staff won a World Championship in the Keirin when he was relatively new to the track (less than 3 years as a trackie).


I guess we'll have to see what events she rides in World Cups as a clue.

No mention of track stuff there. Did they drop the track cranks from their line?

Rotor
 

Different website.
Just a matter of time before they offer it on their track crankset.

Rotor Bike Components

Are you talking about their InPower BB spindle meter? I wonder if it can handle/compute the negative tourque that a fixed drivetrain exhibits.

Again like the Stages only measuring left leg power...

Looks like more marketing than substance to me.

All-New Rotor INpower hides power meter tech inside crank spindle

Interesting thing going on with this crankset. I wonder if the inclinometer will be thrown off by the banking of a drome. Pretty decent sampling rate at 200Hz.

Speaking of BB PMs, whatever happened to Ergomo?

Ergomo - went bankrupt - came back and are still trading... Mobile Power Measurement in Watts - ergomo- THE POWER METER!

Yeah, that's right. Ergomo did do the BB deflection power meter. I'm not sure why they didn't take off. My buddy here in ATL had one for his track bike. It wasn't very stable. He said that he sent it back a few times.

I personally think that power meters should get closer to the feet (i.e. measure using crank arms, pedal spindles, or force plates/cleats on pedals) than further away.

I agree. Either put them at the source of the input (more accurate input measurement, fewer variable along the way), or put them at the the rear wheel so you know how much Wattage is being put to pavement after it's gone through the drivetrain.


It doesn't really matter where you put it in the end, as long as that's where you will consistently have your PM.

fwiw - a close friend of mine is a pro-mech for a team that used Rotor PMs last year - he said that even with the extra support they got as a premium-sponsored-team, their PMs were a living nightmare.
Wouldn't calibrate, wouldn't hold calibration, weren't stable...


he's still with that team, so I'm afraid I can't get into other details that would incriminate him... but I'd recommend on giving them a pass unless their units start getting vastly better engineering.

Mazda concept bike.

Very pretty, but for some reason the handlebars are just a bit dissonant (for me)

Interesting, but those "concept" bikes and "industrial design school senior project" bikes are always designed by people who have never ridden a bike :D

There are so many reasons why this wouldn't work.

it mostly looks ridable except for that front end... would be worse than over cooked canned spaghetti

"least possible parts"

in other words...the same amount of parts as every other bike on the track? :P

And that front end looks like its about to fold under its own weight, let alone a rider into a turn.

Ridea
 

First time I have seen these.
https://scontent-dfw.xx.fbcdn.net/hp...05440898_o.jpg

is it made from vibranium adamantium alloy?

you need matching Captain america speed suit to ride that

@carleton, this company (Ridea) makes a double bolted seat post collar. Top half clamps around the seat post, the bottom half around the seat tube. A little more elegant than the hacked double Thompson set up. ;)

"hacked"!!! Whatever! My setup is a stroke of genius :D

I'm looking around Google and I can't seem to find the particular clamp to which you are referring. Do you have a pic or link?

"Hacked" is a compliment in my book. It takes a genius to hack something into an improved version of itself. But this is the link - RIDEA Headquarter Oval chainrings Crankset CNC lever are Upgrade Component for bikes and motorcycles
Scroll about halfway down.

Thanks! :D

This one?

There's no info explaining what it does and it's not evident from the image. But, I do see text describing the tubing and seatpost diameters.

I'll look into this. This is an interesting way to address this. I wasn't aware of such.

I stumbled upon in when checking out the Ridea site after @Soil_Sampler posted the Capt. America Crank.

hacked
 

custom machined, is the correct nomenclature.

double clamp
 

Quite a few seatpost double clamps.
