    What is the difference between a double and triple chain set?

    I have only had triple sets (is this 3rd ring what my roadie friend at work calls the granny gear??).

    Does it mean that I won't get smaller gears for steep hills.

    Sorry if I sound like a complete novice but .... I am on this subject!!!!

    Thanks

    Welcome!

    Yes, a triple has three rings on the front. You have more range of gears, but along with that comes some overlap. And hills are easier as you will have a granny gear.

    You can also get compact gearing. This is just a double with more of a difference between the sizes of the two rings than normal. You then get more of the range of a triple, but with bigger steps between the gears. It's a compromise between double and triple.

    I hope this makes sense. If not, then just read the other few similar responses you will get as we all fight to be the first to reply.

    Aww thanks Paul! You got in first though :wacko:

    Ok, so I'm fairly bike fit but always had a triple. If you've read my other post, I want to get rid of the drop bar Trek I have *shame*. I quite fancy the Cinelli Hoy Hoy Rats but think it's a double.

    Crank set FSA 34/50
    Freewheel Shimano 12/25 8 speed

    I hope I've quoted the right things.

    I'm just worried that I will look a right moose on an especially steep hill???

    That there bolded be a so called compact. The 34 front and 25 rear will give you a gear which will get up most hills. It's probably not too far away from the triple you have/had.

    For instance I have a triple which is 30 front 25 rear, not so different. A compact will give you a wider spread of gears over a smaller range. You'd need to clue us up on which gears you currently have and ride so we can advise on whether it would suit.

    Sorry, but 'midlands' isn't good enough. We need more detail. We need to know where to look out for the CycleChat jersey.

    You will get one. They all say that they won't. But they always end up getting one.

    Sorry if I'm asking dumb questions or teaching you to suck eggs. Do you mean 1st and 2nd at the back or the front. Generally you refer to the front ones as chainrings and the rear ones as cogs or rear block/cassette. Also with the rear the smallest is the first gear and the largest the last gear.

    So it's useful to know which combination you choose on the flat and climbing i.e. do you ride the large front chainwheel with the rear largest 2 cogs on the flat and the inner chainring (your Granny ring) and two largest rear cogs when climbing, or some other combination?

    Don't know the Scott but I know the Trek.

    Hi Crackly - you're not asking dumb questions at all - it's me!!

    I usually ride either the 1st or 2nd chain rings at the front. The back cassette, I kind of go with the flow - whatever feels comfortable at the time I suppose.

    Mister Paul - WEST midlands, you know - the really posh area :wacko:

    OK, in general terms then, I would say that the compact double setup you've described will suit you well. There is of course some presuming going o there. On the compact you would probably stay in the largest for most riding, dropping to the inner for medium and steep hills.

    You always have the option of changing the chainrings on the bike if they don't suit and the rear cassette, though it's nice to avoid that if you can.
