Hello,

This is the bike I have as my commuter

https://www.giant-bicycles.com/en-gb/bi ... ifications

I want to upgrade the callipers to 105 - Will this be ok ?

Is there anything else I need to buy, cables, adjusters etc

Anybody know of any instructions\vids how to do it ?

    I could be wrong but i am not sure they are compatable with the Tiagra STI Shifters

    Depending on the iteration of tiagra you have - assuming 4600 or 4700 then you can update to the latest Shimano 105 calipers. However if you have an older version of Tiagra - which works on a different pull ratio then you would have problems in terms of set up - older variations of shimano 105 (5600 version) would work fine.
    TBH - replacing your brake pads with swiss stops brake pads is a simpler and less expensive change which might achieve the desired improvement in braking for you.

    The 5800 105 brakes will work fine with those levers and will be a useful upgrade in terms of braking performance
    FFS! Harden up and grow a pair :D

    Have the same bike, upgraded the brakes to 6700 for £40 without issue.

    O/P Here, Ive done the upgrade and the braking power feels fine.

    The only slight niggle is that I can't get the plastic cable to sit snuggly in the barrel adjuster. Even if I de tension the whole thing it doesn't go in ? - any ideas ?

    If you have a metal or plastic ferrule fitted to the end of your outer cable, remove it the outer cable will then fit inside the cable tension adjuster.
