Afternoon all,

Yes another Cassette question ..

I have a Binachi 8 speed road bike with a 12-25 cassette that I feel could do with some more grunt for the hills. Would it be worth changing the rear cassette and if so how would I know what would fit and what size to go for?

The cassette in question is a Shimano brand but I don't have any further information on the GS....

Cheers in advance to all who can help
