Fitting a mtb fork

    The fork on my mtb is finished. I couldn't afford to source one through a lbs. I picked up a rockshox reba for 60% off online. I thought I would fit it myself, but I am getting cold feet now. Anyone know where I could get it fitted, I realise its cheeky to go to a shop now. So does anyone know a mechanic working for themselves who could fit it? Thanks.

    Where you at?

    If you decide to do it yourself.

    There are loads of other videos on Utube.
    It's not a big job.

    Where you located? It is very easy, undo the stem bolts on your current fork, undo the brake calliper and move the hose out of the way, undo the top cap on the stem, and remove the stem/bars. Give the top of the fork sticking out of the frame a tap with a soft face hammer, and the fork should drop down, keep hold of it incase the bearings jump out of the headset

    There will be a bearing race around the bottom of the steerer tube, you'll get that out with 2 flat screwdrivers, don't go full ape on it or you'll damage it taking it out, just massage them gently and you'll pop the race out, put it on the new fork and tap it home with a piece of pipe to get it sitting flat. Maybe clean the headset bearings in a bit of petrol and regrease them before fitting the fork so you'll not have to mind them.

    Put the fork through the frame, put the stem on, tighten the top cap first, not fully down, but snug enough that the fork has no fore/aft movement, then do up the bolts on the side of the stem

    Thank you very much for taking the time to reply. It is cutting the steerer tube I am nervous about. I am in Dublin knocklyon.

    What part of cutting the steerer are you nervous about?


  • Registered Users, Registered Users 2 Posts: 1,002 ✭✭✭dev100


    Basically you just want to put on a new shock and keep same spaces and position of stem etc ???You also need to press in your star nut also, do that last . For cutting of steerer tube just measure length of the old steerer tube and mark the same position on the new one , 2 choices it's either a hack saw or pipe cutter . If you have a hacksaw use some insulating tape and wrap below your cut point on steerer it'll give you a visual cutting line around the tube . Quick lick of a flat and round file to clean the edges . Then it's just pop your star nut in .

    Bring it in to Expert Cycles in Rathfarnham - the lads are really helpful and I'd be surprised if they have any issue with fitting it for you! They might charge a little more than they would if you had purchased the fork from them but that's fair enough IMHO!

    There was a guy on adverts that serviced bikes he use to be based in Wicklow but I think he's in Kildare now. I've heard good reports of his service. He picks up and returns aswell.

    I'll try find out his name.

    +1 Just pay a few quid to have a bike shop mechanic fit the fork for you, will prob cost 10 or 15 quid but you're buying piece of mind also...

    Yea sure install it yourself, it's not hard, just measure twice cut once for the steerer, adjust the position of the disc brake calliper and cables, clean out headset races, inspect bearings, grease up with proper bike grease, ensure everything is tightened correctly and off you go...

    I found putting in the star nut straight without the proper tool was the worst bit. If I were doing it again I'd look at using the bung style nut that was designed for carbon steerers
