New high performance bicycle CRANKSET

[joliverti]

the music is hilarious

[darkcyber83]

The website Revelox.com is no longer available/accesible hmmmmph...

[BenFranklinFan]

Schwinn came out with cranks like this in the 1980's

It was called a "Bio-Crank"

The variation was not as extreme but it was the exact same concept.

[kloeser]

MARINONI!!!!

[ozzyfan2236]

What is MSRP on it?

[jonnie505nm]

cool!! they should make car transmissions gears like that! and motocross bikes too!!

.....lame...

[germankid93]

good if you don't know how to spin properly

[Tesseract0]

This is not innovative. Elliptical chain rings have been around for a long time. I remember having one on my Look back in the mid 90s

[743d]

on paper these ideas are sound, but when you factor in the variety of femur,tibia,etc. lengths the whole thing goes out the window. thats why biopace was such a bad idea, one pedal stroke deficiency is not the same for all people. it also is not a hoax, the black section of the arm moves in relation to its position. on the other hand, thats a mechanical nightmare waiting to happen.

[daFranch1se69]

I would take an Ultegra Crankset over that p.o.s any day.

[glozick]

@daFranch1se69 i second you

AMEN

[fartefactof]

Looks Like ROTOR

[dnm25]

ya what's up with extending cranks plus biopace, that sounds like complete overkill to me.

[pawr1111]

absurd! spend less energy by reducing your upper body movement - THEN LEARN HOW TO USE AN EFFICIANT PEDALSTROKE!!

B.T.W. in the early 80's, oval chainrings was experimental. why are they not used today you think?!

[mikzu88]

Actually oval chainrings are used by many pro's like the Specialized MTB team and Cervelo Test Team. Some had them on their bikes on Tour de France this year too...

[bladedspokes]

... and your handlebars are too wide for you...

[bladedspokes]

Ugh... it's the biopace debacle all over again...

[jdc760]

Wow, this is so clearly a hoax. The video is stretched horizontally so when the cranks are horizontal they appear longer. Note that they also appear skinnier. When the cranks are vertical, they appear shorter, but only because the video is stretched, also making them appear wider. Metal doesn't morph like that.

This would be super easy to spot with a round chainring - it would be stretched, too. The oval chainring makes it harder to pick up on the stretching.

[Tromoly4130]

Nope, if you look closely you can see that the cranks are longer when in front of the BB but shorter when behind the BB.

Combining these cranks with Biopace has to be the worst idea I've ever seen, it's guaranteed to make you so screwed up on any other bike. What happened to things being round?

[jdc760]

No, what's visible in front of the BB appears longer and what's visible behind the BB appears shorter, but consider that directly behind the BB is more of the crank that's not visible from the other side.

Still clearly a hoax.

And really, has anyone beyond this page ever talked about these cranks? Have you seen press about them or seen them in your LBS or on a real bike? Of course not; they don't exist.

[livin4lax09]

1:09  Revelox will make my arms that much longer? WOW

[keithhearn]

Ok, it has all of the questionable advantages of elliptical chainrings, with more weight and more moving parts? meh

[RolfCopterKk]

meh i ride bmx bike.

Buy a doge Charger!

[sippinthefnordies]

this isnt even biopace. it just moves the bottom bracket forward of the saddle more, similar to a shallower seat angle.

[vwrx1969]

Man that's old school !, I had bio pace in 1992

[mhowey]

What makes these any different than biopace?

[mikemonster]

biopace is back from the 90s

[PianoComposition]

This might be the beginning of solving knee problems.

[ReveloxInfo]

The actual design is about 1400gr but we plan to go down to 1300 or lower after.

[gorgefahazadeh]

thats weighs more than my frame

[EVH3730]

I wouldn't buy it until it was 800 grams or less. Carbon Compact cranks are simply the best! If you are pushing around more weight it just AINT an improvement in effieciency!

[duinthadope420]

Carbon yes, compact, no, I gotta sprint it guy

[MASTERCON12]

how much do the cranks weigh? (in grams)

[wojtek1425]

Currently I am testing PowerCranks for improving running .

What is the influence of your product ( if any ) on running performance ?

Any similarities to PowerCranks in biomechanical way ?

[ReveloxInfo]

We don't have measured or evaluated yet the influence of our crankset on running performances. We hope to doing it in a near future with multi-sports athletes.

The biomechanical aspects of both products are quite different. Our crankset improved the wheel power by generating more torque (mostly in the power phase) while the Powercranks help to improved the upstroke/recovery phase.

[wojtek1425]

Thanks for replying .

I am going to focus on PowerCranks religiously for a few months in order to write a report .

If you would consider me in your tests I am a game in a few months .

[representenhiphop]

a can go faster on a regular bike then how fast they go

My Kuwahara had that setup on it 15yrs ago. It was discontinued because your feet speedupand slow down every revolution and it is hard on the knees.

[ReveloxInfo]

I agree about the feet speed variation over a complete rotation. But, the combination with oval chainrings creates a ergonomic, smooth and efficient movement. Like with a conventional crankset, a progressive training with a proper bike fit is very important.
