Got a problem...i've recently built up my new bike with SRAM Force groupset...which was fine until i installed the chain...

I installed it as per SRAM instructions using their "big/big +2" formula and it went on fine.....however now i've set everything up i don't have full range of the cassette when on the big ring..

I run a compact front chainset 50/34 to an 11-28 rear cassette.

Now SRAM say their systems are desgined for full use of the cassette range in either front ring so it should work but when in the big ring i cannot go past the 22 ring (only 25 and 28 left) and it seems the chain is too short as the rear derrail. is pulled nearly horizontal!!

SRAM say my setup is fine with a standard length rear derailleur so i don't believe it's that.

Anyone got any thoughts what i did wrong?
Is it just a case of i got it wrong initially (formula wise)

    as above. you did not do big big and a whole link (1 inch).

    Panic not :D
    Just use another quick link and use the bit you cut off to get the chain length right.
    In fact i would shorten the chain again but just enough that the extra bit added gives the right length, then the two quick links will not be too close together.

    I might be being thick but would i not need three power links to do this???
    Cause you can't undo them?
