Not Coming???-FlangedHighQualityEnoFW's w/dualRowBearings

[MitchJi]

Hi,

EDIT UPDATE (changed title):
Got this today (Wednesday, April 27, 2011):

Mitch,
I finally talked with White Industries. They are working on designing us a dual bearing freewheel. They just needed to confirm a few design issues with us. I don't have any time frame but they are working on it.
Thanks,
Jim

If you would like to purchase a high quality Flanged White Eno Freewheel (or multiple Freewheels) similar to the picture below, with a Dual Row of Bearings please let me know.

You can post to this thread or send me a PM.


This thread was inspired by mmd's suggestion and my emails with Jim at Sick Bike Parts:

If any manufacturers see this, we need a flanged, high quality freewheel with dual row bearings!

Yes!

I sent this to Jim at Sickbikes:

What are the chances of you coming up with a solution?

And I got this response:

Yes we are aware of the problem as it applies to mostly electric applications as the angular loads are much greater with an electric set up than with our gas jackshaft set up. We have contacted White about making a dual row bearing freewheel for us making a much more bullet proof set up. They said they would work on it but we haven't bugged them about it lately. I will contact them again and see if we can get the project started again. I will let you know what they say.

My reply (hopefully not a mistake!):

Maybe I could help organize a group purchase which would help you judge demand (might not be good news) and help fund the project.

His reply:

Yes some input about quantity would help.

Destroyed! A warning to those using freewheel cranks....

bulletproof freewheel

Another option might be a one-way:

I went the CSK route. Smooooooth. And I don't think it will lock up if I crash it. Good luck!!!

If someone can design and equally robust and affordable solution, and its the preferred method, maybe we can organize a small run of parts or kits?

[phyllis]

wow, that´d be super. I want two, depending on width and number of pawls. I want as many pawls as possible.

[Ricky_nz]

Yep, definitely interested provided they don't work out significantly more expensive than the current single row ones.

[John in CR]

Yep, definitely interested provided they don't work out significantly more expensive than the current single row ones.

Since we're helping them correct and serious and potentially dangerous design flaw, we should get them at a significant discount, not equal in price or more expensive.

LOL!

If both were available, and the diff in price was not great, I'd for sure buy the double.

I find it kind of funny that there happen to be so many threads running right now about FW cranks as well as sprague one-ways.

I know the Elation V3 uses a sprague on the cranks. I think this would be perfect if a second support bearing was incorporated as well. Even a sprague has only one bearing row internally. The sprague I use for my belt drives has one bearing row and two sprague rows. So, the holding power is HUGE. However, there is still a need for a second bearing for crank drive type systems. It is not needed for any other application. But, for this specific application, we need it.

Hmm, how much room do we have to work with anyway? Is there enough width for a sprague and a second bearing along side it?

Yes interested -
dual row bearing freewheel from White and Sickbikeparts
If I could get a couple for $100

[recumpence]

Yes interested
If I could get a couple for $100

Hmm, I highly doubt that would happen. Spragues are expensive in the size range needed and the added machining would add even more to this. If I had to guess, I would say something like this (a sprague one-way with second support bearing and sprocket adaptor) would be well over $100 for one.

Hi,

If you would like to purchase a high quality Flanged White Eno Freewheel (or multiple Freewheels) similar to the picture below, with a Dual Row of Bearings please let me know.

Can you clarify if this is a 2 bearing set up, or a single, double row bearing, installed ?

If you read the quote above from his email to me you will know as much as I do. I interpreted this to mean a FW with dual bearings, one on each side of the pawls to me, otherwise what's the point? I'll ask for clarification, if you want, when I update him on the results of this thread.

Hi MitchJi,
I'm keen for one unit.
Cheers,

Well i can see how it would be relatively easy for them to upgrade to a dual row (single) bearing, but much more of a redesign to install dual (separate) bearings.
I just wanted to be clear exactly what HE was proposing ...as opposed to what you wanted

[MitchJi]

Hi,

Reeived this today:

Mitch,
Just letting you know that I haven't forgotten about this. I have been pushing White Ind to work with us to do a double bearing freewheel but he has been slow to respond. I will let you know when I hear more.
Thanks,
Jim

[SoSauty]

Interested in having one, willing to pay up to $180 or so.

This implies the single row bearing model, pictured above, isn't bullet proof. Roughly how much power does it handle?

[kevo]

I'm also interested.

[comradegerry]

That is good news indeed, I will put my name down for 2 of them once available. Thank you Mitch for your efforts in trying to push the case forward, fingers crossed it bears fruit.

There might possibly be a glut of new single row WI freewheels hitting the sale section at discounted prices if the new improved model turns out to be the real deal, thats where mine will be heading if I can upgrade....

[Green Machine]

Count me in for one...

[comradegerry]

Bump....

Just wondered if anything ever came on the dual row bearing flanged freewheel?

Sure sounded like a great idea, especially if White Industries was behind it....

Maybe one day in the future.....

[odedelen]

Hi,
Count me in for 2 please.

Thanks !

The only dual bearing flanged that i know of is this one here . Acs crossfire is better then the eno. http://item.mobileweb.ebay.com.au/viewi ... 2004017013

What are you talking about? Not only is that link NOT to a freewheel, but the ACS Crossfire is nowhere NEAR the quality of a White Industries unit........

Matt

[jk1]

Down the bottom of the add, they sell it as an option. It's the only place i have seen selling them.

Sorry the link above was from a tablet PC and hence mobile ebay- it doesn't show up well on a Pc in that view- this link you can see it better down the bottom:

Here is some discussion of all the different freewheels available By boost juice and what he thinks of the ACS crossfire: There have been many failures of the ENO's and i have personally killed 2* csK 35 Type freewheels so this ACS crossfire should be the strongest design available today, i want to try it some time on my next freewheel failure.

[myzter]

I can destroy ACS Crossfire's freewheels in a day or two quite easily, on my rig... the motor is not perfectly aligned with the freewheel...
The threaded cover piece is not very secure, and must be welded in place, however I prefer another freewheel which is rated at 550 LB/in. Torque and the 16T is only (138g) 4.9 ounces. these are proving to be much more bomb-proof...
