campy 10speed cassettel locknut(13 posts)

campy 10speed cassettel locknutd271
Mar 4, 2003 6:32 PM
I'm building new modern roadbike(last one was 1988) and decided on campy 10 speed.in all the places that I've read it always states that only the cassette with an 11 tooth cog comes with a locknut.from my mtb shimano experience I know what locknut this is. but do I? what holds the cassette in place? the last cog? anyone have an answer ? thanks

think of it as a hollow bolt. this pic would be looking down on the head.

the 'bolt' threads into your cassette body and the 'head' of the bolt applies pressure and holds the gears in place

You have to buy the lock ring separate for 12 tooth cassettes. The gears slide onto the hub then the lockring screws into the hub, holding the cassette cogs in place.

Good choice on components. I replaced my vintage 1987 bike last year and went full Record. I think you'll agree that it ROCKS!!!

What kind of bike are you building up?

it seems your story,conjecturing,might be similar. I have an old all Italian Pinarello montecello(?)(forgot the model) which I haven't ridden in 4-5 years.been mtbing and mtb racing and have been lusting after new road bike. the pinarello prince looked good so that's what it is.I'm not really up to date on roadbikes at all but I'm realizing how much it going to cost. ouch!

Your Montecello wouldn't happen to be the one they sold back in the late '80's that was painted the color of the Italian flag would it? I absolutely loved that frame and almost bought one but my team was using Scapin's so I went that direction. I still see them on e-bay every once in a while but I really have no need for it now.

I tried to find a Prince last spring but there were none to be found in my size in the US and they had no idea when one would be available.

I've bought Chorus and Record 12-25 10 speed and it came with a lock nut. Maybe it came with the hubs, but I know I didn't have to buy it seperate. I'm pretty sure it's the same nut for any of the 9 or 10 speed cassettes.
LOCKRING COMES WITH THE HUB...Spunout

That will fit a cassette with 12 or 13 small cog. If you want to use the 11, the cassette comes with a special lockring (or the 11 IS the lockring) to fit snugly.
locknut and cogs are seperate...BenR

The locknut and smallest cog are seperate pieces just like Shimano. For some reason, campy provides locknuts with the hubs, so cassettes that have a smallest 12 or 13 tooth cog don't come with the locknut - if you lose or somehow destroy the one locknut that came with your hubs, you are SOL and have to track one down on ebay or sell your bike to pay for the special order. Leave it to the Italians to make things difficult.

The locknut that comes with the hubs does not work on cassettes with an 11 tooth cog, so all 11 tooth cassettes are supplied with the appropriate lock nut. They both work the same way and are easy to mix up if you have multiple cassettes, but you'll figure it out when they don't lock down correctly. They both require the same tool to install but are not interchangable. Hope this clears things up.

A few years back, Campy changed the diameter of the lockring by 1 mm. So now there are four - the older diameter (smaller?) ring, 1 for 11t, 1 for 12+t; and the newer diameter (larger?), again in 2 sizes. If you do much fooling around with multiple Campy bikes, you end up needing to keep a sample version of all 4, just so you can figure out what the heck you're dealing with!

I don't know about what comes with what. I do know that the lock ring for the 11 is different than one for say a 12 or 13. The 11's OD is a little smaller so it doesn't interfere with the chain. All of the cassettes need a lock ring.
