    I'm not familiar with suspension and current ones are shot and we're never great

    What should I look for on chain reaction for circa 200 - 300

    It's the specialised one



    Thanks

    They are almost certainly 100mm travel. You need to find out is the steerer tube straight or tapered, what sort hubs your wheels have (dimensions, quick release or through axle), and what size wheels you have (26, 27.5 or 29 inch).

    Googling the exact model written on the frame and/or fork lowers, with the year, will get you more info than anyone here can supply.

    Assuming it's the 2013 model, and also assuming that there aren't different wheel-sizes available: SR Suntour SF13-XCM-LO 29", 1-1/8" steel steerer.

    If you're looking at new forks, they'll need to be 9mm QR friendly, unless you have a bolt-thru hub with an QR adapter attached (very unlikely unless you've done so yourself), although I would second what Mr. Grieves has said first. All your forks could need is a service & proper tune-up which will be a damn sight cheaper.

    Thanks for the info

    A prof mtb mechanic said they are were cheap forks and best bet was replace them a few years ago

    Well, you've got a bit of a balancing act to do if you want to replace the forks.

    The widest set of possible fork options would see you upgrade your front hub to bolt-thru (typically 15mm). Why? Bolt-thru axles provide a stiffer front end which gives a better all-round experience in the steering department, especially when it's all going a bit hairy. They're also becoming more and more popular as a fork option, and much like finding [decent] 26" forks is becoming a bit harder to do these days, so too is Q/R, especially where larger wheel sizes are concerned. But whilst that may sound great, it also involves extra cost of hub + rim + rebuild.

    On the other hand, you could just go find a 29" fork replacement with Q/R and 1-1/8" steerer.

    A third option if you want to go all-in but don't want to stump a considerable amount of cash in one go might be to consider doing the wheel upgrade with a hub that has Q/R adapters available and having your current fork serviced, which would do for the interim, and then replacing it at a later date.

    Just to stress, option 2 is by far the most straight-forward if you are set on replacement although you may find yourself limited in fork-choices because of the Q/R requirements. Doing any of the other options could well see you with an overall bill north of €500/600 depending on what hub/rim/rebuild/old fork service/new forks you go for and you may well just feel it's better off saving up for a new bike instead. Like I said; bit of a balancing act.

    On the other hand, you could just go find a 29" fork replacement with Q/R and 1-1/8" steerer.

    Yup, straight-up replacement of the fork with something better without changing anything else about the bike.

    Your current fork options are either 80mm or 100mm; juding from your photo I'd guess it's 100mm. That said, best give it some measuring tape to be sure. In any case, I'd go for the Rockshox gold solo. You have two options for it from CRC;
    1. 29", 100 mm, 1-1/8, w/ crown-lockout @ £235.99
    2. 29", 100mm, 1-1/8, w/ oneloc @ £295.99

    You'll want to check the euro prices as I'm viewing the site from the UK. The difference between the two is the oneloc is an additional thumb-control that you mount on the handlebars to adjust the damping on the fly. If you're not bothered with that, you're adjusting damping from the fork crown.


    Edit: I'd also check and double-check that your wheels are 29". I've gone off the basis of you saying it was a 2013 model Rockhopper, but either the rims or tyres should have some indiciator on them suggesting what size they are.
