SRAM 10spd chain and shimano Utegra jockey, are they 100% compatible?

[NotSoBigBen]

While out riding my training road bike I was thinking what a 'frankenstein' group set it has ....

 

Shifters - 10sp Ultegra

FD - 105

RD - 105

Chain - KMC out of an MTB build kit

Crank - Ultegra with 9sp FSA chainrings

Cassette - SRAM (not sure what 'model')

 

Somehow it all works together OK ........

Clearly not the rather expensive OG1090 (red or black) one that makes a resounding cacophony RRRRRRRRRRRR noise

 

I'm going to try the standard 10spd PG-1070 and see if its quieter, just need to find a shop that has one in stock....

Its the dome of the rear combined gears, it works as an amplifier for drive-train noise.

 

Update: Definitely the Red Cassette that was noisy

 

Replaced my Red Cassette with a standard SRAM cassette and its much quieter, first tried a few km's with the old chain (Shimano HG) still on and it was dead quite, then put a new Sram chain and its really quite, now I'm looking forward to riding without hearing a whole orchestra of teeth whiRRRRing behind me the whole way...
