Cassette question(4 posts)

Cassette questionOverhill
Jul 12, 2003 5:25 PM
I was cleaning chain and cassette, with rear wheel off bike. I noticed cogs loose, and the lock piece[?] was loose. I tightened it by hand, and the cogs are now tight, but I don't have a Campy cassette tool. Will this tighten as I ride? Is it safe to ride [ride sheduled tomorrow morning]? Is there some other way to tighten this cassette? How tight does it need to be? Any suggestions most appreciated. Thanks.

You're SOL unless you can get one of your friends to bring a Campy cassette tool and an adjustable wrench before your ride. It'll take two minutes to fix.

The lock ring needs to be real tight, 50NM. You must have the campy loclring tool. Best to use a a torque wrench.

When all else fails, go to and read the instructions. They have just about anything you need in pdf format.

You need the Campy lockring tool. It looks very much like the Shimano, but it is slightly different. You may be able to carefully use the Shimano tool to get the lockring tight enough to get you home in a bind, but I wouldn't recommend trying it unless you are stranded and have to.

The Park tool to fit this is BBT-5 and also fits Campy Bottom Brackets. It should cost you less than $15 to purchase it at you local shop. If they don't have one, ask them to order it for you.

I have worked in a lot of shops in my time, and many of them only have Shimano tools on hand... not too many carry proper Campy tools. They just aren't as popular, as most bikes sold are mountain bikes, and most mountain bikes are Shimano... so if you have a Campy bike, purchase the tools yourself and learn to use them or at least take them with you to the shop if they are working on your bike. It's a good investment. Don't always count on the local shop having the tools for you.
