Hi,

The shifters and cassette need to be replaced on my 2005 Santana Soverign

We want to go ahead and upgrade to a 10 sp setup
At the same time, we want to be able to climb steep >15% grades without hurting too much. Our lowest gear ratio is 0.88 if could get it down to 0.8 that would be great.
Currently we have Ultegra and XTR RD. the cassette us 11-34 and the chain rings 30/42/52
Besides the cassette, chainrings, FDR and shifters what else we should replace.

We welcome any comments or suggestions.

Can someone help us with especific brands and model numbers/sizes to best achieve our objectives?

Thanks in advance.
