Sram XX Cassette

[georges]

hi,

 

Can anyone please tell me difference in the 1090 and 1099 10 speed cassette and what chain would you recommend. I'm currently running a PC 1071 but not sure of the cassette.

 

Thanks.

Chainreaction Cycles and CWC both sell the XX XG 1090, yet the SRAM website list only the XX XG 1099.

 

Both descriptions look the same, maybe there is no difference aside the number or 1099 could be the 2012 version.

 

I have used both the PC 1090 and PC 1091, both work equally well, the weight and price being the only difference
