    Why not go 10 speed and use a compact

    Thanks for reply.

    Two reasons:
    i) I don't know why that might be better than what I have
    ii) Shifter on the left has three spots, shifter on right has 9 - i thought i'd have to keep it the same. Or at least - I'd nee more knowledge that what I have.

    I only use the middle front chainring. If I'm downhill I'll use the larger one though not often.

    To change to a double compact, you'll need a new right hand shifter. The left shifter will work with a double chainset ( just adjust the limit screws so it doesn't change onto the 3rd (smallest) chainring)

    Thanks. All sounds a bit too much for me.

    Otherwise am I on the right track with the above products - will they fit the bike. Is it worth upgrading the quality for a commuter or just change them more regularly.

    Crankset you've linked is 6/7/8 speed, you're running 9 speed so there is a possibility that the chain will be too narrow and wont work. For a new crankset you also need to make sure you've a compatible bottom bracket, or change your bottom bracket e.g. most likely square taper but may not be. For a cheap 9 speed crankset on that site you could go with the Altus but it is very low geared for a commuter at 40/30/22, on a tight budget I'd tend to go with the Alivio with 48/36/26. Chain and cassette should be fine. Personally, if you're doing this level of a swap out, I'd also change the BB and replace all the cables. If you're doing the work yourself you'll need a cassette tool, a chain whip and crank puller along with the usual spanners, patience and a few emergency cans of beer.

    Brilliant - thanks for that.

    This is the crankset that is currently on it - should I stick with this or take the other suggestions you made? It might avoid needing a different BB.

    Again, this is what is currently on the bike so was thinking of just direct swap.
    Do you reckon a 10 speed chain? Not sure what type of chain is on the bike.

    Planning to swap out all the cables also.

    Will invest in a set of tools.

    Best advice on boards ever!



    Really appreciate the help with this - there's a lot of diff component types out there. Can be hard to determine the different levels of quality within Shimano eg Acera, Alivio, Altura etc.
