    I'd say it would need a chainguide. Don't want the chain to bounce off.

    What front hub are you running? A chain device, oh and maybe a different frame as 4x does give a good hammering and iirc the hardrock is a crosscountry frame.

    I'm going to guess it's the standard front wheel, so a cheap Specialized one.

    Cross country frames can hold up to a little rough riding, if the OP gets serious then they could look into getting a decent 4x frame.

    since a lot of 4X stuff seems to be basically beefy XC gear i would guess the hardrock frame would be OK for a beginner (my wife has a hardrock and its a nice tight little frame in the smaller sizes)

    On E13 ISCG 05 chain guides such as the LS1 there is a plate which sits behind the driveside cup.

    You won't need an external BB as the driveside cup on BB's is fixed, so the plate is wedged between the cup and the frame.

    that will need quite alot of work.
    for chaingide get a superstar one as it's only £35 and comes with a BB mountable adapter. new chainset, new wheels will make alot of difference and better forks

    Spending all that money on a new frame, forks and wheels for something he may not enjoy is a bit pointless don't you think?

    i din't say to get a new frame but i take your point

    A strong rebuildible front hub/wheel will be a good investment.
    I thought the OP was intested in 'getting into' 4x racing, if he just wants to try that style of riding take some time at a bmx track and see what breaks, the trouble is if you are starting out you will crash then a bit more jump ruggedness is better. The forks are fine, the drivetrain is okay until it breaks, brakes are subjective and some fast rolling tyres never go amiss.

    A steel frame from one of the smaller brands will already have iscg mounts, better geometry and stand upto the knocks, ally frames in this catagory have massive tubing and weld areas, my STP0 is built like a tank.
