Topic: Updated! cb750 re-spoked process PICS

[techy5025]

Buchanon's includes a small vial of the nipple lube with each set of spokes....and a warning to be
sure to use it. In my case the spokes were thicker then the ones that came on the bike and looked
like jevfro's. The "outties" are the ones bent at more of an angle of course...but this was for a standard
18 inch rim.

You did a great job polishing the hub....I am impressed!

so - i mounted the newly spoked wheel and can't decide if there is an "offset" or not.

the chain seems to mesh nicely with the gears and though there is some runout discrepancy in both X and Y axis i can't see why a little spoke-tweaking won't take care of it.

if anyone reads this who KNOWS, for a fact, that a well-balanced 750 wheel does NOT have significant offset, that is, dislocation from front sprocket to rear sprocket caused by incorrect spoking, PLEASE SPEAK UP!

i really don't want to start a new thread if i don't have to...Chet was pretty clear about what offset is, but i don't have any confidence that he has experience with these bikes. in fact he did not mention any first hand experience, so it could be that some bikes do have this (offset) and others, ours, not.

hoping for some reassurance...

i  though the offset was for chain clearance on the tire.... thats why you have to have an offset(if any)... if the chain clears the tire, and the alignment front to rear isnt out, then i say leave it...

Well,
The wheel is on and everything is working/looking great!

Thanks again for everyones help and support!

CBJUNKIE: I don't know this for a fact, but I don't think you would want the type of "offset" you are talking on any bike because it would cause the chain to track uneven (maybe I'm still not understanding this...) I think cben has the right idea.  As far as I've seen/heard I think"offset" is used to put larger tires on or to mate a diffrent transmission to a drivechain that doesn't line up.

nononono, you guys are not understanding my question.

i don't want offset. i'm asking about offset because the spoke guru told me that some bikes have offset that is managed by shifting the wheel sideways when the spokes are loose and then tightening the wheel in place - then, after that is set, the process of truing can begin.

it's two separate things he's talking about.

my question is: do these bikes even have this? or, can you simply lace the wheel, true it and go?

to be honest, after putting the wheel on yesterday, i can't see the need to move it over at all. it does need to be trued, but the chain and gears seem to mesh pretty well just as it is.

however, my reticence is based on the fact that i am "eyeballing" it and i'm not sure if this is precise enough to tell if more or less offset is required.

this is my first time - i'm just trying to make sure i get it right...sorry for being dense - somebody take pity on me!!!

you are not going to be able to change the chain off set using the spokes..... the position on the actual hub is set by the spacing in between the arms of you swing arm, if there is a discrepancy between front and back ,on the chain and sprokets, it has nothing to do with the hub and wheel relationship, and everything to do with the spacer configuration on the rear axle.

   and as i sid earlyier, the only reason you would need to 'offest' the rear rim and hub, would be to put a larger tire on and gie the clearance on the chain, or if you front to back wheel relationship is out..... that is the only reasons i can see for even needing to 'offset' the rim and hub.... just my thoughts...

[cbjunkie]

that seems right to me, too.

i guess i just started to wonder after the info that Chet gave me...i agree with you that it doesn't seem that offset could be accomplished in any meaningful way with the spokes.

i'm gonna true it and go.

thanks cben.
junkie out...

too easy mate, good luck...
