Hi guys,

I run my tiagra 10sp deraileur on a 36t cassette even tho it's only rated to 34t. Works fine with no issues.
I need a new deraileur and can only get a 105 11sp locally today which I believe is compatible with my 4720 tiagra shifters.

Again its rated to 34t. Will it run on a 36t?

Thanks

Not done it myself, but read 11-40 works with a goatlink.

The simple answer is ‘it might’

Depends on how much B screw adjustment you have and also if you don’t have a slack chain in the small chainring combos. But if you have it working with tiagra then no reason why 105 won’t play well instead

If it doesn't I know the Goatlink works as I was just running one of these with my Ultegra mech on a 40t cassette till I got a GRX mech.

I’ve previously run a 105 with a SRAM 11-36 with no issues whatsoever. It was 1x if that makes a difference…

I can confirm the 105 GS mech works perfectly the 36t cassette.

(And grx 400 10 speed shifters)
