I think its a mistake moving away from ISIS. I would have bought a disc hub, but I want to use my own cranks.

Same. I love the hub design, but would use different and lighter-duty ISIS cranks in my own build.

Glad to see the company expanding offerings, which implies growth. I imagine this is a very hard market to thrive in. Best of luck to those at Mad4One.

Not ISIS? What were they thinking?

If it was ISIS, I'd consider buying a disc hub, oh well

The hubs are made of ergal, that is why the ISIS pattern is different. The entire hub and crank are EXTREMELY light and strong. I am using the non disk hub on my 24inch street unicycle and I have yet to bend or break the hub or cranks.

Yes it does seem kind of odd to have a different ISIS pattern but after you feel the weight difference between all the other hub and cranks you seen realize the MASSIVE benefits of having a light hub. Your control of the uni goes up, hiking/walking with the uni is a lot easier (I rode my uni on campus both semester this year and the light weight made it a joy for riding through crowded hallways and walkways, also made it nice for when i had to carry my uni in class).

These hubs and cranks are quality, each and ever hub is made one at a time in a small machine shop in Italy that machines parts for the Bugatti super car. Yes they are expensive, "you get what you pay for."

Jacob,

Are they using a spline standard from mtbing or is it their own standard?

I.E. are there any other crank brands that fit those hubs?

I an guessing that the pictures shown here are just computer models. Please tell me if I am wrong but it looks to me like the splines on the hub don't match up with the splines you can see on the green cranks suggesting these aren't the real deal.

Ergal is just another name for 7075 Aluminum, no reason for a new crank interface.

They're prototypes I believe, not computer models. You'll be able to see them at unicon.

On the question what the type of spline is it they answered on fb:
It is a MAD4ONE system developped by us. With this spline is possible to have Ergal hub strong as CrMo Hub with 30% of weigth.

+1

This interface forces a consumer to use the matching crank. Many people would choose another crank made by someone else if given the choice. That choice has been revoked. The market will vote with their dollars to prove whether or not this was a good idea.

I'm also turned off by the claims of a lighter hub increasing my enjoyment while riding through hallways. All things within reason, hub weights don't matter. Especially when riding in hallways.

I wish people could just sell their products on the merits of good, simple design.

I'd have been interested in the hub based on it's clean elegant design and one-piece machined construction. the cost associated with machining the hub is higher than other methods. As an educated consumer, I'm aware of that and would have been willing to pay extra.

I suppose this sells things to people who don't know better, so the youth?

Personally, I already have more than a dozen ISIS standard cranks in lengths from 125-175, four ISIS hubbed unis, so if it ain't ISIS I ain't buying. I suppose it would work for folks who only ride a uni the way it comes equipped, that's just not me.

As to the use of "new" materials and claims of weight loss and high strength, let's be honest, there are no new materials that are economical enough for uses, even Ti is very expensive. I would hope that "the youth" would recognize that such claims are fluff

Propriatary cranks and hubs, novel idea, too bad they won't sell many.

Ive been riding a unicycle for 8 years, I have seen many designs come and go. Personally I myself do not care about weight but more of the reliability of the part. After riding with light weight parts you soon see all the advantages of having them.

I mean you guys care about having a light weight 36inch tire so why not have a light hub? This hub is for the extreme genres of riding, the type of riding where you do things in the air that happen in a blink of the eye.

Yes the ergal is the 7075, an extremely hard aluminum! Currently KH is making his new cranks out of them and I am extremely excited to see how they hold up. These are not computer models, they are in fact the real deal.

I have been riding with Mad4one parts for a year and a half now and have seen and rode some parts that werent the best. These new cranks and hubs are so far amazing. Yes I am sponsored by them, I am not saying all of this because of that. I am completely for the innovation of new parts for the unicycling community and I think mad4one is doing this quite well.

Also just to clear things I dont just ride in hallways, I also enjoy like to ride a lot of street.

Because the tire is far away from the wheel axis and contributes significantly to the moment of inertia - contrary to the hub.
