    Hi all, I’m quite new to the mountain biking scene and have only recently taken a major interest in the sport/hobby. I own a Mongoose Rockadile ALX, yeah I know, quite a low spec bike compared to some that you lot own!

    However, I didn’t buy the bike for mountain biking, it was just something cheap I found that seemed decent enough for getting me from A to B with a little off road excursions along the way. Last weekend I went to Afan Forest Park just to have a nose around, following the Penhydd trail, (not sure if any of you are familiar with the area) and really enjoyed the experience!

    Anyway, I noticed that my front suspension whilst fine on surfaces I had been riding previously, seemed really rough along these single track routes. I was thinking of upgrading the forks to something like rockshox dart2/3’s (currently SR suntours m2025) as I don’t really want to go through selling the bike as its quite new plus I’m a student on a limited budget so would struggle to pay for a better end bike!

    I’m aiming to spend around the £100-£120 max mark. What would you guys recommend?

    Thanks for reading!

    it depends what forks you have? If you have coil/oil forks, you may find that a good service will get them working at their best again for a few £. However if you have “elastomer” forks, dump them and buy some ~£100 forks in the sale and you’ll transform the front end… If you swap the forks, you’ll probably find the headset’s past it’s best as well, so add £20 budget for a new cartridge headset…

    Don’t be tempted to buy longer travel tho…you’ll upset the geometry and slow-down the steering…

    I have spring coils and they’re not adjustable in any way either. I don’t think they really need a service, they haven’t accumulated a significant mileage yet.

    I just want some forks which are a bit more responsive for some rugged xc terrain, I’m not goin to be doing any big drops or jumps with them.

    Currently the travel is limited to 63mm, I was thinking of going up to an 80mm set. Is an extra 17mm going to have a major impact on geometry and steering response?

    The headset is 1 1/8″, is there a particualr make you would suggest as an upgrade?

    If your frame can take 100mm forks, then these would be a great buy:

    I have a pair of Manitou SX 80mm forks whick I’m giving away (see for sale section). May not be an improvement tho…

    I just bought a pair of these:

    A bit over budget, but I am really pleased with them…

    I’ve actually been looking at both of those forks myself! Trouble is I don’t actually know what size forks the bike can take, it doesn’t say in the manual and I can’t seem to find out online.

    Is there a way to determine this from dimensions of the bike perhaps? I will also try and find out from the manufacturer.

    I did read your for sale post and saw the forks but I’m quite a distance from you and would rather a spanking new set.

    A stupid question perhaps, but a friend had me thinking, do the forks mentioned here, or indeed any forks, have the same width between the dropouts to fit the axle of a “standard” 26″ wheel?

    Front wheel “skewers” for quick-release hubs are a standard length, so the forks are a standard “width”.
