well if your looking for a good sturdy downhill bike that is cost effective i would say buy a specialized big hit 3, both me and matty have got them. they cost around £2000 but take some serious damage. i have just started donwill and i have hit trees, rocks, roots everything and it is still in good condition with nothing breaking so far. on saturday i went to hamsterley and nailed my front wheel on a rock, the tyre sqashed right down and it bottomed out on the rim and i didnt even get a puncture. they are a good bike to learn on, as they dont cost as much as others, like a orange 224 (£4200). buy a big hit, they are awesome.
