Bike gearing explained !

Can anybody explain this to me.
Currently have FSA Compct 50/34, with 8 speed rear 26/12. Ok at home but off to the Alps this summer. last year copied alright on a triple. So best option might be to change rear cassette. On the internet Shimano HG 50 8 speed, seem to sgo 11-32, 11-30, or even 11-34 !, Which would give me the equivalent of the triple ??
Thanks

get thee to BikeRader.com, young man. Plenty of Biketechs there will help you with gear ratios

Your triple was probably a 28 or 30t in the small ring anyway. I'm guessing from the fact you have a compact, it's a road bike. So a normal double will have 50/39 or 52/40 and a triple will have 50/39/30 or some such.
Not that much difference, do some extra training and you won't notice

But as the above says, get over to bike radar :rotfl:

None will give you the equivalent of a triple as you will always be missing roughly 2 speeds. Depending on what riding you're doing I'd sugest putting a triple back on. I've ridden there on road, downhill and all mountain bikes and had to change setups on each. It's a small cost that could make or break your holiday when put into perspective.
