That is called Gila.

But again... every uphill, there is a downhill. Depending what kinda downhill you are referring to.

LOL... There's nothing that is not aggresive in DH bro. Have a trail walk in Kiara DH trails or PCP black trails. You're like bringing a fork to a gun fight 

Unless you're talking about descending rather than pure DH, then lain cerita lah.

I presume, his DH is like 2K kinda DH. 

DaBomb HT frame was used in one of the earlier urban DH competition. Maybe you can consider those kinda frame.

EASY. you wanna do DH, then just concentrate on DH. dont fool around with AM or XC or like that. DH has a different skillset and mentality - so just focus on DH.

secondly, about your budget. ok this is a tough one, but easily remedied. get a DJ frame and invest loads in wheelset. a marzochi DJ fork would do just fine. and a fullface helmet.

get that, then you can ride DH already. off course there's a reason why a full-sus bike + triple crown fork is required to ride DH, but that's when you are faster and when you are ready to take on bigger jumps like in the AU3 track (3 car length gap). so far kiara, pcp, dsara damai track everything can be tackled with a DJ bike.

before you get the wrong idea of not doin other type of biking, what im trying to say is concentrate on DH and ride XC for leisure or when u need to work on stamina. not ride XC but try try cuba DH. like that both also you wont do. dress like gei in XC then wanna clear a gap with an XC bike. kanot.
