any one have a cassette hub free wheel go bad on any type of drive but esp. a rack mount / GEBE ?

i have started having an odd, as yet untracable, inconsistant, symtom that is baffling me.

SOMETIMES, at speeds from 30-36mph at steady speeds or accell. i'll get what i'll call a dull faint clumpclumpclumpclumpclump FEELING more than heard kind of chuffing tapping, i don't know how to define, wierd, rotating pesterment.

it will start and stop on it's own and never during or after any decernable conditions directly leading to or away from it.

i checked my wheel bearings, drive mounts and alignment, evrything around the wheel assembly that i can think of. i don't know anything about the construction and working of freewheels so that is still suspect to me.

one other thing. it sure appears that my drive ring has been moving on my spokes, there are clean spots on the spokes both inside and outside the drivering, but i checked the distance from the ring to the rim at every connected spoke and they are all dead even. i wonder if rain water can run through the gaps and cause this to appear this way ? (just thought of that )

anyway any ideas or suggestions apprec'd.

Are your spokes tight? Or are they loose enough to let the nipples crash around in the rim eyelets? If your hub and freewheel doesn't have play or make popping/grinding sounds when its off the bike and you're fiddling with it the hub is fine. I would check the spokes as the GEBE drive ring puts stress on them possibly loosening them or snapping them over time. Good luck.

I had a freewheel sieze on me, on a happy time

It was a drag to get off the wheel to replace it.

Glad you are riding so much.

yea it's the sound of that SIEZE idea that haunts me.

been there done than, once had a front whel bearing dramatically fail and sieze on my '73 HD SuperGlide while traveling 55mph on a 4 lane highway.

it's the sudden riding on the tank with your knees jambed under the bars so far you can't counter steer the slide that freaks you out the most.

the some how leaving the road on the right side and falling over on the shoulder was a relieve.

other than this , the ride is great and i look forward to it every day.

thanks,
steve

just back from the garage, thought i'd look at the spokes yet again.

found the cause of those odd marks on my spokes.

the drivering is flexing in and out about 1/8" each way. don't know how i missed that before, bu tyou can put your thumb against the ring and with little pressure the ring will deflect and come back. it does it either way.

this is very odd to me , as the wheel is straight and solid, having no runout or wobbles at all.

boy this stuff bugs me.

who else is putting atleast 200 miles a week on a GEBE system ? any quirks ?

You are supossed to epoxy the drive ring to the oversized spokes.

And time you run over 20 MPH "COUGH, Max legal speed in AZ. " Or use your motorized bicycle for a lot of miles .
You destroy bike parts.
For example Large Phillipino's constant consumption of rear wheels.


Check on the gebe site I believe he epoxys the drive ring.

yes my drive ring came visably epoxied to the spokes, it's all gone now.

today i went thru a bunch of aggravation re-truing my drive ring with split bolts and a dial indicator. it's so close now that if the indicator dial didn't exagerate the variations it would be VERY hard to see it at all.

this was an intersting exercise as it showed up some things. previously it seems that my belt was stretching at a trackable rate and i needed to increase the amount of tension i was using.

with the ring re-centered and using the same belt, the tension arm went back to the position i marked when the belt was new. what this shows me is that the ring WAS creeping up and down on the spokes making it LOOK like my belt was loosening up.

also i was making it worse by using increasing tension AND leaving the tensioner locked down full time. i really believe ,now ,that when not in operation you should relieve the tensioner wheather you are using the spring or a static position and force yourself to remember to replace it as part of your startup routine.

we'll see how things go in the morning.

Steve, How about some pics of your split bolt set up. I considered using wire when the time comes. I have a pin hole in the dom pipe where it is welded,oil runs down the pipe and makes a mess, I jb welded it 2 times with no luck, put 3 layers on it tonight, will see in 24 hrs, any other ideas other than welding, dont want to mess up chrome. Got stopped by a motorcycle cop today, he just wanted to look at the goose,wanted all details so he can make one for himself! He called another cruser that had a camera so he could have pics of the set up, he also was in awe.

sure i'll get some tonight. it ain't pretty , but it worked to a degree. i'll see on the way to work if they hold.

i only had 10 so i'm on every other spoke for now. i think i'll get more and do the rest tonight.

yep, people LOVE MB's, people that come in the lumber yard are constantly asking about mine.
