Hi
I'm a newbie and just have a quick question it may sound a bit stupid. On my new bike 2 weeks old when I'm in certain gear combinations, when I'm pedalling my gears/chain make a weird whirring/grinding sound this has only just started and was fine for the first week and a bit. Is this just the gears and cabling settling and stretching a bit? And I just need to make some adjustments. Or am I using wrong combinations that are causing me problems? Sorry if it sounds a bit stupid but I've only been riding a road bike for two weeks.
Thanks

    You aren't using wrong combinations are you? Big ring at front with smaller cogs at back and vice versa.

    Er, big rings at front and small cogs at the back is fine. Big-big and small-small are the ones to avoid.

    You are right about looking out for cable stretch too. Your indexing will start to go off and you might find you change gear but you just get a clicking noise from the chain but no gear change until you try again. You can easily tweak it using the inline adjusters. Bike shops often offer a free 6 week service to check for these problems.
