DA 9070 11-30

I normally swap my 52-36 down to a 50-34 when I do the yearly proper mountain trip, this lets me keep my 11-28 on which is low enough for me on the long stuff.

What I'd really like to do though is just keep my 52-36 on and ideally run an 11-30, which would give me the same range (well a smidge more), a bigger gear to push against on the descents and the only downside is a bigger gap at the top of the cassette.

Anyone got that ratio running? It's outside shim's recommended range but I know they tend to err on the side of caution.

    It's probably fine, but you'll need to check the chain length to make sure that it won't cause problems if you accidentally end up in the 52-30 combination.
