I have a GT Avalanche 3.0 Disc 2009 18" which has seen at least 800+ miles cross country and a bit on road. I paid £300 for it. It has a few scratches shown below. I have recently replaced the tyres (they've seen 3-4 rides) and the disc pads about 6 months ago. The forks are quite temperamental and basically have lost most of the rebound in the coil spring (What you get from cheap Suntour forks). How much is it worth?

Use that link to see the pictures of the bike.

Thanks.

you might get £60 – £70 in the local free-ads.

150-200 quid

care to give a more specific price. jammy says 150 – 200, wwaswas says 60 – 70.

Always someone on the lookout for a bike like that, bang it in the classifieds for what you would like for it and prepare to haggle, its a nice popular size and a nice looking bike.

£200 would get some interest I would think, but I am no expert, except I know it would cost a lot more to build up.

sorry, I was probably a bit harsh – the damage looked worse on first inspection. I'd say half what you paid for it really.

Guidelines are:

s/h but brand new & current = 30% off RRP

s/h, bit of use & not too old = 50% off-ish

No idea what kind of market there is for that sort of bike on here, try it and see.

As im quite young i got that bike when i was naive and knew nothing about bikes, thinking wow its really good. Turned out i was wrong :'(

I'd say 50% of what you paid for it.

it's not a bad bike though, fork is questionable but aside from that I'd say it's a pretty solid entry level MTB. Probably a bit on the heavy side but then you can spend '000s shaving grams, which is best left till you have a decent disposable income, frankly.

If you've had it a full year and feel the need to invest more (ie you're enjoying the sport and want to move up) then fine, otherwise I would keep riding it. it's not a bad bike.

thanks for the comments guys. Really appreciate it.

£150, Stick some nicer forks on it, then replace the frame and then bits as they wear out.
