...the only worry i'd have is about the plastic wearing over time or breaking some of thge finer plastic parts off...
There is very very little stress on any of the plastic parts. In terms of wear, the area that "resists/drags" is nearly 200mm^2 this compares with less than 1mm^2 on the steel balls of the current designs... There really is a lot of life in this part before it wears out, I would be very surprised if anyone ever wears one out even with decades of use.
I just watched all the videos and am a very happy person right now as George says some things that I've been saying for years.
I'm super glad he mentioned the part about the tolerance between the drive side shell bearing inside internal bearing race having a loose fit to the drivers outside bearing race and this causing problems.
I can't remember if I posted it on here or on Instagram, but G also corroborates the reason I gave why they want with a 3/8ths female axle on the drive side.
This looks like a super durable hub and I will be getting one, if not more than that. My only real question now is, Will it crankflip?
Glad to get your approval. Crankflipping is more likely to be successful than with current designs because of the "stick-tion" feature of the plastic.
Two questions. One, does the clutch require being all greased to hell, and if so will it be done at the factory or will it require teardown before use?
Two, is this actually the g-coaster, or do you still have another design on the back burner? Seems like I remember you mentioning lots of fiddly little internal parts and tolerances being hard to achieve for it on a full manufacture run
It will work fairly dry, but I would always recommend a good amount of grease. It should be pretty well greased from the factory but if it does need more you dont need to open it up, just use a grease gun to inject through the adjuster hole and it should work its way around.
G Coaster is radial engagement, this is axial engagement. G Coaster is meant to be the big shift, and the Clutch just a refinement of the threaded clutch mech we already use
Yes. This is a stepping stone to the G-Coaster. The G-Coaster has been dormant for a long time because we just couldn't get factories to take it seriously; they would make one prototype, mess up the hardnesses and then take forever to try to fix it. In the end, it seemed sensible to do the best job we could with the original design and hopefully get enough sales history to persuade factories to do all the extra work needed to tool up for the G-Coaster. This design does still have some minor flaws left, bearing life will be shorter than ideal (the angular contact bearing around the driver is still going to wear faster than is ideal, so it will probably need to be replaced every couple of years or maybe less if you want to keep the hub feeling perfect (but it wont explode without warning like the old driver bearings did)) and we have to make separate left and right hand versions etc. BUT it is a very useable hub that is leaps and bounds better than anything else on the market. In fact, it is so good, that I am a little worried that there wont be the need to develop the G-coaster at all...
