Newbe needing advise on wheels

jaysav82

Hi, brand new to MTB. I have a bike from ebay and need to replace the front and rear weel and at the same time change the rear sprocket set. been looking for bargains as dont want to spend lots but there seem to be lots of numbers i dont understand with the rear sprockets and wanted to ensure i buy ones that will match the wheels i get. any help, advise or sugestions.

What bike is it.
How many gears do you have at the moment.

jaysav82

22" GT frame. Got 26 " wheels currently with 7 speed cassette but shifters are for 8 speed.

cooldad

You need an eight speed cassette then (and chain). Pretty much any freehub will be compatible, so just a matter of picking some wheels.
How much do you want to pay.

jaysav82

Well bike was only £60 from ebay so did not want to spend to much or might as well of bought a new bike. Maybe £20-£30 for the pair of wheels and hub on there own. Then i have seen cassette at about £20 or less. Do you know what the numbers are about with cassettes. They say sometimes 11-30 or others.

cooldad

11-30 is the number of teeth on the smallest and largest cogs. Larger number makes it easier to pedal.
At that price you will probably need to go second hand on Ebay or something.
Do you need disc or rim brakes?

jaysav82

Rim. The frame does not have the conections for disc. Do I need a specific size to fit on an 8 speed cassette.

cooldad

Nope, standard freewheel fits 7, 8 or 9 speed cassette.
What you want is something like this

Thanks for the help. did not think i ould get such good and dlear advise.

Just make sure whatever wheels you get the rear has a freehub. Some older or very basic ones take have a screw on freewheel - normally in 5,6 or 7 speed. As long as you aim for 8 speed you will be fine.
