Any question answered...

Yep

Bonza, 8.5cm it is.

A swift bit of hole creation with a key will be required as they now put two holes in for zip-tie use:

...yadda yadda..My 10 speed Campag Chorus Compact Chainset needs a new outer ring, a 50 tooth with a 110 BCD, preferably in black but cheaps trumps aesthetics on this one..

But will Veloce rings go on Chorus crabon cranks? We need an actual aficionado.

Sorry off topic but, Anyone in/know anyone in the states thats willing to send a frame over to the uk by any chance? if you do drop me a pm please, would be much appreciated
Thanks

This is annoying- it took ages to lever the sprockets off as they were pretty firmly sunk into the material of the freehub.

Is there, I don't know, a tougher freehub- maybe a titanium one?

I am assuming that this happens due to the freehub being soft alloy btw.

I read somewhere that a loose lockring can also exacerbate that problem

Mine was on pretty tight.

There are Ti freehubs, and steel ones, and aluminium ones with steel drive faces, and there are better designed cassettes which join the sprockets together so that the torque is always spread across a wider contact area. Take your pick.

And there are puny cyclists who don't have to worry about such things :-)

For now, file off those burrs so the splines are nice and square again before you put the cassette back on, or it'll just screw itself even further on. But yes, alloy freehub bodies are DUMB.

Ok, to narrow this down a bit, the wheel is a 404 FC with the 10 speed hub/freehub, and the cassette that came off is an 11-25 DA 7900, the cassette that went on is a 12-27 DA 7900.

I'd hazard a guess that it would be cheaper to replace the freehub for something sturdier than to replace two cassettes of similar quality?

It doesn't help you choose a new one, but I just read this (http://www.slowtwitch.com/Tech/Cassette_How-To_-_Part_2_3257.html) which explains some of the backstory. I'd guess Shimano have a TI cassette you can use?

If Zipp did proper freehubs as an option it would be.

ftfm

Shimano's lovely Ti DuraAce freehub rotor obviously won't go on a Zipp hub

On the other hand, SRAM's XG1090 cassettes are available in 11-25 and 12-27 and have a wider footprint than the individual steel sprockets in a DA cassette. Only £200 each :-)

sigh Well beyond my pay grade now...

I imagine that XG1090 cassettes will be on clearance shortly though as they are flushed out of inventory for 11 speed.

^Wishful thinking

...paging Tester or any Campag afficionados......
A quick browse thro interwebs also brought up this

http://www.ribblecycles.co.uk/sp/road-track-bike/chainrings-stronglight-zicral-7075-110mm-camp-9-10-chainring/strochri520

I think what you want is a stronglite aficionado

It doesent mention anything about compact so one would assume it would not fit and that the chainring is for standard campy cranks.

BBB makes or atleast used to make black chainrings for campy for affordable prices. Can you live with 48t?

You may find better price / other tooth numbers if you google em, just took the first one that came up.

EDIT: This should be good? http://www.dotbike.com/p/10550

cheers Tester, Rive Gauche and babyboybjorn for your replies, ^ this is now the leading contender, good find.

thanks a bunch, i laugh in your expensive face Campag!

@Dammit .. was going to suggest the Am Classic 10speed clip kit to stop your cassette digging in but it's not compatible with 7900 cassette's according to Am Classic ..

Posted in case it's of use to someone else

Why does my rear track wheel (Navigator Carbon) have a suicide hub (freewheel thread on both sides)? I know for track use you don't need a lockring, but I would have thought they would give you the option.

Would I be able to use the same wheel for TTs? Legally/practically?

Would I be able to use the same wheel for TTs? Legally/practically?

I dunno about the TT rules and regs, but I wouldn't. Simply due to the fact that there's gonna be traffic during TTs, you don't have to contend with that on track. Yeah, there are other, possibly appalling riders you may have to slow down for, but you're more likely to have to slow down faster when there's traffic around.

I wouldn't want to run a cog sans lockring around traffic, ever. Especially if I'm giving it the beans.
