    I'm currently looking into replacing a rather heavy clunky Shimano c051 Chainset. I've somehow managed to slighly warp one of the chainrings and because it's a budget chainset I don't have the option of changing the chainring (since it's all welded together).
    I'm looking to spend between £30-£50 on this. Is this reasonable?
    I've been looking at the following chainset upgrade options:-

    Simano Alivio mc-20
    FSA Alpha Drive

    They both seem to fit the requirements (including the correct chainring sizes, chain type e.t.c as well as the ability to change a single chainring if required), however I'm a little unsure of compatability with my bottom bracket (BTy30 Tappered BS 68mm). ???

    Am I right in assuming these will work ok with my current set-up? Should I be sticking with Shaimano (both front & rear mechs are Shimano)

    Any help or other alternatives would be much appreciated.
