Does somebody know what kind of bearings the STmartin coaster uses? It has an 3/8" axle by the way

http://blog.brakeless.ch/blog/freecoaster_stmartin

looks like a khe clone, hopefully with bigger bearings. I would give up pegs forever if it meant better bearings

It's a KHE clone. But since it's 3/8 it probably has bigger bearings.... or?
It says it uses a 3/8" female axle, so maybe it's just an greyhound with the stupid eas system

Backwards lol

I'm sure it's thread in post/3piece axle. They'd have to mess with the spring ball setup to get 3/8 to work. It would be a sick hub with beefy bearings tho. khe logic... If its broke, only fix the shit that didn't need fixed.

Naw, the Greyhound has different size flanges. this looks like it uses the Astern style shell. Pretty much an updated version of the Geisha Flat.

Spill the beans...

Honestly, it's nothing new. Thrust bearing behind the clutch, bushing driver setup. I'm trying to make it happen while recording all the part numbers to make the bushing driver work and have someone else be able to duplicate it.

nice. ill keep following you on that bushing setup. ive had some success with a bushing/needle bearing setup before but that was in a chosen hub that has 3 of those little bearings. im going to work on getting that setup going on my federal too which has just shit the bed so it would be interesting to compare. what material do you use for the bushings?

My little contribution.
This is a Affix/KHE style coaster I machined down.
I turned down the non drive side flange and re-drilled the holes.
I femaled the axle and extended the thread in the non drive side so the thicker cone nut can be replaced by a thinner one giving more room for a hub guard. I also made a narrower non drive cone to give more room as well.
It has a thrust bearing behind the clutch, and I've been looking into bushings for the driver.
The lower shots have older B6 ti bolts.

Looks really good!

Kinda similar to a Greyhound then I guess. I regards to the shell anyway.

So how can I make my Reverse crank flip?

dead on chain alignment.
ensure driver bearings spin glass smooth (replace frequently)
add axial thrust bearings behind the clutch

condrbkr · « **Reply #43 on:** April 06, 2012, 12:48:37 AM »

Will I be able to crankflip on the Ratchet?

super_chief · « **Reply #44 on:** April 06, 2012, 12:51:29 AM »

should be able to, yes

the original version (first came out) had too tight a clearance between hub shell and chain which caused drag (i found out first hand). those hubs should be long gone unless there's one collecting dust out there in a bike shop
