hi thanks for looking,

i have a cheap bike. GT Agressor XC3 and im in need of a headset and bearings.

i am not sure what size i have to buy or what headset. i think its oversized but unsure.

i only want a cheap one, around £30 – £40.

if anyone knows could you let me know.

thanks alot

If it's an 09 then you probably need a semi-integrated headset – there's plenty of choice below £30 – http://www.chainreactioncycles.com/Models.aspx?ModelID=39381

But any doubt on what you need, or fitting it, and you'd be best off paying your LBS a visit.

its an 08' model. thanks for getting back to me

If it's this one:

Then it looks like a standard aheadset type, for a 1 1/8" steerer. Just take it to a shop and ask them what your options are. I suspect a pair of caged bearings for only a couple of quid will probably make this work like new.

And £30-40 is by no means a cheap headset!
