when did record cassettes go ti?(14 posts)

when did record cassettes go ti?Bonked
Jan 20, 2004 6:51 PM
i just bought a bike off of ebay that was sold as "full record." everything else on the bike seems to be record (everything is labeled as such) and it all seems to be 2001 or newer (the levers are carbon and the outer plate on the rd is carbon) but the cassette looks exactly like my chorus cassette (i.e. the drilling pattern is the same and the largest 4 cogs seem to be made of steel, not titanium). is this just an older record cassette that is now chorus (like the carbon shift levers and rd for chorus 2004) or did i get taken for a ride? when did campy add the titanium cogs to the cassette?

thanks!

Just kidding... :-) Don't exactly know when they started to put ti cogs but the 'standard Record cassette'comes with steel and ti combination. You can also buy all ti cassette as an option (not popular because although lighter they wear out faster.) Chorus cassettes are all steel but I believe they are called MK2 series cassettes along with the Record cassette. I have all ti, ti/steel combo and all steel but I prefer all steel for everyday riding since they wear better.
BTW there are no markings on cassetts...6was9

as to what group they are such as Record since each cogs are interchangeable/ cross compatible within each given speeds regardless of what group they are.
nevermind the question below...you beat me to it! n/mBonked

thanks for your response. is there any way to tell the cassettes apart other than the ti cassettes seem to be darker than the steel ones and aren't drilled out?
No, I don't remember...6was9

and I don't know since I am not looking at one in front of me but I think the only way you can tell the difference is the color. It helps to have good lighting and clean cassette(usually there is pretty obvious color difference); I just looked at mine and I can't tell the difference!... I should clean them.

I just took two of my cassettes apart and ti cogs are stamped either on the cog itself or on the carrier/spacers for the grouped ones.
Be thankful you didn't get TiKerry Irons

It wears like butta (about 5X faster than steel) and the weight savings are small. If you're losing races by fractions, then the Ti cogs might make a difference. Otherwise, . . .

my other record bike has a chorus cassette for that same reason. i'm just curious about if i should leave negative feedback or something...

thanks for the input!
I wouldn't leave negative feedbackB2

If you're that concerned, contact the seller and try to work something out. As you said "i really don't care too much".

IMHO - If you confirm for sure that it's a Chorus cassette and the guy tells you to take hike or something, THEN.... it's up to you to decide if you want to leave neg feedback.

Good Luck,

Sounds like you got standard Record (nm)Mariowannabe

Try using a magnet on the last four cogs. A magnet won't stick to ti.
that's a good idea!Bonked

i actually ended up talking to the guy this morning and he was really cool about it (gave me some $$$ back on the purchase price). he said that he switched to the chorus for the better wear properties and i have a chorus cassette on my other bike for the same reason...so all turned out well!
