C'mon Ted, make the cranks 100g heavier and release them. I don't want them because they'r light but because they look so beautiful

I agree with drjones96. How can anyone have such an opinion on a piece of equipment no one has used. Ted with release the cranks when he is ready to release them. So anyone with a negative comment should keep those comments to themselves until the cranks has been released and fully vetted by the early adopters who will buy the crank first and give us their opinion on them.

By the time these come out there will be a new benchmark from Shimano/Campagnolo/FSA or whoever Its like buying the best PC money can buy, as soon as you buy it its obsolete.

Interesting pictures. I thought sharp edges in machined metal were supposed to be stress risers.

I'd like to congratulate Ted for doing it right. No use bringing something onto the market that isn't ready. Better to be complaining about them being late than complaining about the injuries you might have sustained if they failed. Looks like the black and white photos were due to the cranks not being anodized yet.

Well I have waited a long time as a tester but I can really appreciate Ted wanting to get it right before releasing the cranks. Too many times in the bike industry, and the industry I work in, see companies that are too quick to the market with products and the consumer or end user winds up being the testers and R&D departments. This was pretty evident by the number of failures or issues that Zipp, Cervelo, Powertap and others have had wanting to get their products to the consumer.

I'm happy waiting plus it will be tough to pull my Clavicula's off my bike to test these cranks. Hey that sounds like a great reason to build another bike!

Hmmm... the brand is Zero Gravity, not "Feel the Gravity", Lord Vader.


Those few pictures look great again. Can't wait for my crankset to arrive. Meanwhile Zero Gravity got some nice coverage for their crankset in magazines, but still do not have it on the market... rather a pity, but that will all be forgotten if we'll have it on the bike, isn't it?

Don't bash guys for having fun at Zero Gravity's expense. The company owes them nothing, and they owe the company nothing. I realize some of you will be getting a free set and are trying to keep your attitude positive because of it, but don't deprive a person a little fun because of your agenda. It is almost comical the way some of you defend the crank design. He has a product that is years behind schedule. He "wants to get it right?" Correct me if I am wrong, but he is doing simple CNC work to aluminum to make a bike go forward, not trying to discover a way to make cold fusion or some other highly complex molecular process happen. It isn't rocket science. I don't even want to think how much revenue he has lost with the delay of the release. Not to mention the bad press he is getting as a result of revealing them at Interbike 1992(he he he) and then not producing them for years later.

They can be, but if the level of that stress is so low it's inconsequential, then I suppose fashion can prevail.

Really, it's not useful to talk about a stress riser without talking about in context with design parameters, material, test results, and etc.

FWIW, I think the new ZG design looks hideous.

I think you've over simplified things by a lot. Yeah, there is a product that will be CNC's. However, in the time between when that product was designed and today, the designer left, the factory was moved, and who knows what else has happened. None of us sit in on their company meetings.

The idea that just because a crank only makes a bike go forward means that you should be able to produce one just by flipping a switch.....well, that's bollocks. By the same thinking, Shimano and Campy should have had their electric versions ready years ago; SRAM should have only taken a couple of weeks to design the relatively few, simple parts that make up brifters, derailleurs and the rest of the lot; and no bike manufacturer should have to spend any time at all doing testing.

I'm also sure that ZG never considered, at all, any of the other crank failures there have been with lightweight cranks: Pulsions, Time cranks, Propellors and similar cranks.......nah. Not worthy of nary a concern.

Heck, it's likely that ZG and the related company only work on the brakes and the cranks, so they've got all the time in the world.

The new ZG-crank looks fine indeed – but from at mechanical designer’s point of view I do not think they have come up with the right design that is ZG worthy.

It sems like ZG is stucked in the early '90. Look at the inside of the arm. Com'on - it is like they are desperate to loose weight so they have drilled a lot of holes. They can never achieve a crank that can beat FSA, Campag or DA by the use of small holes



Is that the way to go?

Look at campagnolo or FSA.





Or Cannondale SI og Dura Ace for that matter. That is the way to go.

And no, I don't have a problem with ZG - I think that their brakes are the best - period.

The design of the Zero Gravity is much stronger,
since the others like Dura Ace / FSA are hollow they will bend or failure earlier and is less stronger then the ZG design.
And I wonder in how far customers can use the warranty,
my left arm had already been replaced without problem at Shimano Germany,
and now I got a issue right crank at the places where you mount the bolts of your chainring which is bended during normall use.
(it only got 500km, 269 euro's) and has been sended to Shimano Benelux and they're going to do nothing with it.


Hope that this will be also on it like Ted is saying.

Why is your frame hollow?

The reason why ZG cranks have holes in it instead of being hollow is because they are CNC machined. Campa and Shimano cranks are forged.
It has nothing to do with being stronger but with the productionmethod.
