Hello, I am re-vamping my old trusty steed. At present I have a 7 speed shimano cassette on it (from when I was young!) I am attempting to change it to a 10 speed (I have new STI levers) Unfortunately I can only get 9 of the sprockets to fit on the hub. Can I run it with my 10 speed levers and restrict the travel or do I need a new hub or lever? The hub is;Shimano 105 FH-1055. Thanks
