Campy cass. locking ring (Dah!)(6 posts)

Campy cass. locking ring (Dah!)pinarello
Apr 12, 2002 6:05 AM
Last year I was trying to put on a new cass. on my wife's Pinarello. The unit would work but there was some play in the spacers which caused it to sound like it needed constant tuning. I measured the new one and compared it to the old one and noticed some discrepancies. I called campy and they could not offer any suggestions other then call the bike store and have it exchanged or get your money back. Well I feel sorry caused I called Excel which was the bike store I bought it from and they could offer no solution to the problem other giving my money back. Well I thought it was just a fluke and decided to order another one and guess what same situation. Well my son also has a up to date campy equipped bike and I decided to look at this differently this time and use his locking ring. Well to my amazement there was a difference in the style and it worked. This tred is just a FYI and comment, please show some mercy, try not to shame me to bad. Catapult

There are two lockrings available.... one for cassettes with an 11 tooth "outer" cog and one for the 12-13 tooth outer cogs. Did you change from an 11 to a 12 tooth outer cog?????

Yep, The little lady wanted a 26 tooth, to the best I could do was to order a 13-26 to replace the 11-23. You sound like someone that has been here or know's what the heck is going on. It's funny no one else had the intelligence to detect this quirk. Your the MAN. Thanks and hopefully others will not fall into this dilema. Catapult

Branford Bike is a good source for Campy questions like this, they publish plenty of info on the website about which fits what.

My SO and I have 5 sets of C-10 wheels and 7 cassettes all of different configs. Eventually we would have slipped and made this mistake.

I will not shame you. I will only thank you for sharing this quirk. Hey, I'm a former wrench and not proud to take advice freely given. I've also watched professional shop mechs who've been in the business for years make a complete balls of a job from stuff like this.

I've built a WHOLE bunch of C10 bikes in the last 2 years and BELIEVE me if there's a mistake to be made I've done it.

I'm also a bit of a tinkerer....... shaving Campy delrin shims to make custom C10 cassettes, tearing apart deraileurs to find out how they work and modifying them. Oh, that was one of my mistakes..... hahaha. BTW: if you ever get around to mounting a 13-29 cassette on your medium cage C10 der........... DON'T SET UP THE DER THE WAY CAMPY RECOMMENDS. I.e. the chain must be a bit shorter than recommended to keep the upper jockey wheel from riding on the 29 cog. GRRRRRRRRR...... that one burned up too many hours to even count, and it turned out to be a silly chain adjustment.

I'm also STILL learning ..... ESPECIALLY re your posts on racing. BTW: I'm doing my second RR next weekend and I'm hoping my recent interval workouts wlil lower the shuck factor. ;) I'm doing my first crit the weekend afterward. I'm scared!!!! ;)

BTW: My vendor just wrote me that my LX10 Dream cross frame has arrived. He's prepping the frame and will ship shortly. Now, I've got to learn some new stuff..... tekro brake setups, those funky cables you recommended, CX setups, etc. Should be a fun learing experience. Hey, speaking of those funky cables.... do you have a source for them???

good luck with the racing season.
