help with new chain and rings

ginger8

hi newbie here ( bin in the background a while)

started riding again after almost 20 years out. used to ride bmx/mountain bikes but now im on a road bike

my problem is. i need a new chain and rings but not sure what will fit with what.And theres so much choice.???

chain is shimano HG73 for a 9 speed (better/lighter/stronger)
double ring set 48/34 (110 bcd RPM crank) i would like to go up a slightley different gear ratio, but dont understand the ratio's.

i have around £60 to spend on all 3 items and would appreciate some advice.

i currently have a carrera vanquish bike i bought second hand off ebay if that helps anyone.

thanks

Wiggle do a good selection of chainrings. You do not mention the cassette, this is normally the bit that wears out and is replaced with the chain. If you want higher gearing a cassette with an 11 tooth high gear will get you up to a good speed.

Assuming Shimano gears, you'd be better going for new chainset, cups, chain, and cassette. You should get all four from Ribble for your budget.

Also look at Stronglight, you could get a complete chainset with bottom bracket or just chainrings to fit your existing cranks. Sram are good for chains, comes with a powerlink which makes removing for cleaning much easier.
As stated above, if you need a chain then the cassette is most likely worn and needs replacing.
