yea i had that happen to my sram 9.0 cassette. the 18t cog just sheared right off the "composite" carrier. i thought my king was acting up on me, but it was just the cassette. got it warrantied, sold it, and bought an lx that i made into a 5 speed one.
Did you warranty it through a bike shop? I should be able to find all of the gears for it in my tool box somewhere. For the replacement I will probably get a Shimano105 road cassette where the 5 gears are joined together.
I did the same thing to my DA cassette.Problem being there is not enough alum around the rivet.I still use a DA cassette.However the different tooth combos have different designs for the carrier arms.The pictured is a two
cog carrier .The 3 cog has a deeper more reinforced riveting.
Hope yer OK!
Well I have an alum cassette shell on my CK so having a one peice cog would just cut it up. Since the carrier is wide it doesn't cut into the shell as bad. I will probably switch to shimano105 as the first 5cogs are joined together... as far as roadie stuff goes. It seems that a lot of people use it... So its not just me :eek3:
my ultegra did this as well, I just replaced it with a king kog and surly singleator in the "tucked under" position - it's out of the way, neat, troublefree and light. works good. I'm using a 20/17 ratio at the moment and it's all good. And I can (and do) use a BMX chain as well...
