Can anybody explain this to me.
Currently have FSA Compct 50/34, with 8 speed rear 26/12. Shimano. trek 1000 ,Ok at home but off to the Alps this summer. last year got on 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
