    Hi all, I’m new around here so hello – and go easy on me!

    I’ve got some events lined up for when summer arrives, namely the Dartmoor Classic and Etape du Tour and hills are not my forte (strange choice of events given my weaknesses, but they’re the ones we’re meant to target right!?). I have a compact chainset and 11-28 cassette. My question is how bigger cassette (sprocket) can I squeeze in on my 105 (5700 short cage) rear mech? Was wondering specifically if a 11-32 would fit and whether the real world gains would be significant?

    Any help appreciated,

    Kev

    And that answer is helpful how? :/

    Cheaper option than the new tiagra is def a 9 speed older shim deore mtb mech , same cable pull as 10 spd shim road gearing , still if money isn’t an issue then buy the new tiagra

    Maybe swap the existing derailleur for a new 10 speed tiagra derailleur and a 11-32 cassette?

    Tiagra 4601 is the GS version that will handle 11-32.

    This may affect the required chain length, so you’ll need a new chain to go with that too.

    As far as I understand, you
    As far as I understand, you are on the limit with a short mech and your current compact and 11-28
    If you want to go larger you will need to change to another rear mech,

    A 9 speed Shimano deore will work and allow you to go to a 32 rear if needed
