Hi there, I'm new to this forum and in fact any forum so hopefully this won't sound to daft. Last year I bought a careers zelos from halfords and completed several rides bit my main one being a triathlon. At points in the race I was unable to pedal fast enough to keep up with the wheels (spinning out?). I was wondering if it is possible to change the cogs to larger ones in order to he able to go faster?
Thanks for any help received.
