best gears for an 8speed cassette
i'm musing away today, and have another question to put to the forumites.
my gios has an 8speed 600/ultegra tricolor RD, with a double up front. The bike currently only has 7 speeds on the cassette due to whatever the previous owner felt was right, but i'm thinking of choosing a new set of ratios. i know this can be discussed (argued) until the cows come home, but here's a few things i'm dwelling on:
it's current little cog is still a 13T, i'd like to get that down to a 12T or even 11T for hammering it. However, at the other end of the equation it's got a 24T currently, and i wouldn't mind something even easier for the hills. I'm hitting a ride later this year with some notorious hills, and despite my training, i'd like to have a 'granny' gear for the later stages!
so, with an extra cog in there, what would be my best range options? given i want a big one at one end, and as small a one as possible at the other end.
can't be done? wishful thinking? can i up to a hyperglide cassette option? its on a ritchey wheel, its all circa late 90s i believe.
