Advice on changing cassette

milleman

Thinking of buying a Specialized Sirrus pro but will want it changing from a compact to a tripple set up, have been assured that this is quite easy by my LBS.

Forgot to ask them but is is possible to change the rear cassette from 12-27 teeth to 11-28 teeth?, on my current sirrus I sometimes need a taller top gear when pushing hard downhill.

thanks

No problem.

changing your cassette wont effect your top gear, as you are already at the smallest sprocket (11 tooth) When they fit a triple, make sure the largest ring is bigger than your current one.
