I'm excited for this:

Gearbox | Efneo

I currently use a 2 speed Patterson crankset on my pavement bike for dinglespeed effect. I want slightly more range. Pretty slick either way though.

Hope the price is compelling, once it becomes available. The rad thing with the Patterson is that it is so absurdly inexpensive.

Problem with the Patterson system it will not work on a mountain bike 68mm only most mountain are 73mm ,your next best 2 speed would be the ATS Schlumpf this retails at $325 .and is made under license in Taiwan to strict specification and save you quite a bit of money over the German made one. The Efeno does look interesting , I would buy the Ats Schlumpf as it has a history of reliability the Efneo is new to the market who knows if it reliable ?.

Hmm, I didn't know that the Schlumpf was being manufactured in more than one place. Interesting, thanks for the info. It looks like a good system but I don't want to have to modify a frame.

Got an email response from Efneo clarifying that the core product is the right crank, and all it needs is a place to anchor against the frame that is static, for anti-rotation purposes, and you could mount the right crank on any square taper BB spindle.

3 speed mid-transmission fat bike, can't wait!

Exactly. Pair this with a Phil 100mm square taper BB (since the cranks don't know how wide the BB is) and you've got a simple fatbike drivetrain. Appealing for wild rides where some gearing is needed, but a der-based drivetrain is going to get kilt, stat.

From the horse's mouth. I hope they hit an appealing price point since they're going the crowd route. I wish them luck.
In January we are starting (at last!) our crowdfunding campaign. We need your help to spread the word!

We have chosen some of the most interesting articles on Efneo for your convenience in one e-mail.
If you use Facebook, Twitter, Digg.com or any of the similar sites, choose the one you like and share it with your friends!

Looking forward to seeing this in the metal. I'm on the list. :)

Sweet.

I see they added a fat bike option after I had contributed for a 68mm BB shell version - though I don't think it will matter, given the type of crank spindle.

Not yet. Had forgotten about it. :)

Better give them a poke.

Their last update on the Indiegogo blog was 4 months ago. Ready to move to mass production.

Edit: just looked at their site. They have a shopping page, and no mention of it not being immediately available. Price is $495 now. I've sent them an email. Will report back.

Didn't get any response to my email, or a later contact through their enquiry form.

Was about to start taking further action but this arrived:

Efneo - delays explanation

Dear Contributors,

I know many of you are wondering what's going on and why you don't get your gearbox. Some of you may even suspect being cheated.

In fact, we have already delivered almost 100 units to our backers and we are still shipping. Some of these people have published their reviews (mostly very positive) with photos. You can google them easily.

You can also take a look at some media reviews:
Review: Efneo GTRO 3-speed front gearbox | road.cc
http://www.bentrideronline.com/?p=11407#more-11407

The problem with the deliveries is that we are not able to ship in bulk now. That is because there are three parts in the gearbox that we are still manufacturing in very small quantities and that makes our manufacturing capacity very limited. Fortunately, we have finally found a quality supplier and placed an order for large volume to be delivered in January. That's the point where we can really accelerate with the deliveries.

Some of you are also asking why we are selling the product through dealers since we have not delivered to all our Indiegogo backers. Frankly saying, without sales we would not be able to raise additional funding, continue the project and fulfil our Indiegogo commitments.

Please accept our sincere apologies for all the delays. We know how frustrating they are.

Wishing you all the best,

Franek & the Efneo team

I'm pretty frustrated with them right now. First world problem and all that. The fact that you can order one today and have it ship this week just doesn't sit well when they've had my money for ~3 years already, and I still don't have anything to show for it.

That and the fact that they've stopped responding to inquiries from people whose money they've already spent.

Agree. I was thinking about approaching the Polish Police before their most recent communication came through, so decided to give it a bit longer.

I've sent 4 messages without reply.

Maybe we should start a FaceBook group...

Certainly I'd be wary of ordering one directly from them right now. I'd want to see it on the shelf in my lbs.

Maybe a few comments dropped in the reviews on their website might get them to hurry up...

Hi guys. I noticed on another site that Mikesee finally got his, and he's got it rigged (edited) on a Pugs. Kudos to you and any others for helping the crowdfunding on this. I've been anxiously waiting to read any reviews.
For the record, I have a couple of Pugsleys (one regular 26" fat on Marge Lites, the other 29"x3" on Rabbit Holes), and both with Shimano Alfine 8-spd hubs. I like my set-ups, but I'm often wanting more range. Since I ride the beach a lot, I currently have my gearing set low, but I can change things up with different chainring/cog combos.
Mikesee's recent blog posting with his o.p.p. caught my eye. I had been wondering about an Efneo/A-8 combo for wider gearing range on my 29+ Pugs ever since I first heard about Efneo.

Edit: Now I see that Mikesee has a single-speed Pugs with an Efneo. And he's taking it out in the boonies! At first glance I thought he had the Efneo paired with his Alfine 11-sp hub.
That got my noggin spinning. The singles-speed fat wheel set that I pulled off my #2 Pugs when I swapped it over to 29+ and Alfine 8-spd suddenly has more potential!
I really hope that the Efneo proves to be robust enough for mtn biking and fat-biking. I'll be keeping my eyes open for more reviews, as I remain a potential customer. I think that I could make it work with my A-8 and a 20t or 21t cog.

I've received my Efneo crank with 100mm spindle for use with an English threaded fat bike. I have not installed it yet as my attention is compelled elsewhere. I'll try to follow up in the next week or so.

I've had mine about a month now. Two 'out there' trips so far, plus a handful of commutes. It functions perfectly, but makes a fair bit of noise -- sounds like dust in there, squeaking intermittently.

Has anyone seen anything about a need for or ability to lube it?

@Velobike: Do continue to send politely harassing emails. I had to repeat my order details three times, while waiting a month or more in between each message sent.

If you got one for a fat bike, make sure to mention it is NOT for the Sonders E-bike. Something about a asymmetrical left crank vs a symmetrical left crank.

They have never replied to any communication. If it wasn't that you & Mike had got yours recently, I'd be thinking it's a scam.

What email address did you use.

(I've used their form on their web page and also [email protected])
