Hi guys. I have just purchased a wilier izoard xp veloce which comes fitted with 50/34 chainring and 11/25 rear cassette, would it be possible to change the configuration on the rear, say to an 11/27 or even 11/28 without breaking the bank?. I am planning on entering a few sportives this year which are hilly events and think i may struggle with to higher gearing.
