Hey all,

I have a set of Chris King disc hubs (HD rear conversion) and originally had Mavic 729 laced to em 3X 32spokes using DTChampion straight gauge 2,0 spokes and have been running a Shimano XT 8 spd cassette on em with no issues.
Yesterday I relaced those hubs to a set of Spank Spike rims using new DT champion 2.0 spokes, and now the same cassette will not slide on the drive sheel all the way wihtout hitting the spokes. Shimano cassettes have this nasty cage that sticks out behind the largest cog by a good 5 or 6mms and this is what's hitting my spokes.
Only thing different I did was lace the wheel backwards from what i had it originally (drive side trailing spokes on inside, disc drive trailing spokes on outside).
My best bet at this point is getting a SRAM PG850 cassette and hoping that it's flush behind the biggest cog like the current 9sp SRAM cassette i own, as that fits on fine since nothing comes out farther than the lagest cog.

I just find it weird that I'm having this issue now. The wheel is centered, close to perfectly straight and definitely round.

I've called Chris King and they gave me the we've never heard of that deal. Weird for a company who makes the "best everything" as they put it to have never heard of something but oh well, I figured i'd give Ridemonkey a shot.

Any thoughts?

Pics?

Was there a spacer behind the cassete?

+1 on spacer behind cassette.

Does the cassette tighten down without any play? I believe the 8 spd isn't supposed to need a spacer, but in this case, it may.

I'll try and get pics tonight.

I thought the spokes only cross at their last (3rd) crossing before going into the rim.

I'm pretty sure there were no spacers originally. I didn't try tightening the cassette since it didn't fit right from the get go.

The SRAM 9spd cassette slid on without any problems though.

At this point I think i'm gonna take my changes with the SRAM PG 850 and hope the back end of it is flush.

why is every single customer service rep I call today a douche bag?


SRAM -1
CK -1

you didn't dish the wheel properly. that's why the customer service people are not agreeable to you -- you're blaming them for what you did wrong.

rebuild the wheel, dish it properly.

 

[Shortbus]

I never blamed anyone, I called trying to get help.

Thanks for all the replies!

edit: wheel is centered/dished correctly.

I have a thought: On some rims the spoke-holes in the rim have a left/right bias.

If your rims are like that, check so that you haven't by mistake laced the wheel with the spokes "on the wrong side" so to speak.

dishing!!!!

 

[Shortbus]

well here's a crappy shot, for whatever it's worth.

I looked at my Balfa wheels that also run a XT casette, and the cage/pins runs VERY close to the spokes, maybe a mm or 2 of clearance.
I'll rethrow the wheels on the stand and check centering/dishing but the wheels sit centered in the frame.
I have a SRAM 850 cassette on the way and they are flush with the big cog so hopefully this won't be an issue anymore.

Thanks for all the help/suggestions.

Oh yeah, didn't think about the spoke hols being off center, good thought. I did check and they are symetrical.

More power to wheel building. Some day i'll get it right =)

How about a closer shot of your freehub body, I don't think this is a dish issue.

Have you serviced your hub recently? Done anything to your cassette? Or was it FOB (fresh-outta-box)?

Also, a picture of the backside of your Shimano cassette would be helpful.

Did you stress relieve the spokes while building them up?
