    Evening guys,

    Well i’ve stripped the Giant XTC29 frame which has now been sold on, started on the build of the spearfish.

    This is where it’s all gone a little wrong.

    The steerer on the fork is (i think) too short. I’m running a 45mm stack height stem, with a Hope headset. (Not fitted the head doctor insert yet, still has the SFN installed). So my problem is that the steerer comes up short by 22mm. So, i’ve been doing a few calculations and what i realistically need is a 20mm stack height stem. A 15mm would be even better…

    I’m not hugely concerned about the length/reach on it at this stage as i’ve no idea what the bike is like anyway hahaha.

    So lads… inspire me ?

    (I don’t want to go down the road of selling the Fox forks and replacing with another set of Rockshox (which IMO are not as good).

    Is it a normal 1 1/8th headset with external cups?
    How about a zero stack headset? That would give the difference. You only need the steerer to come till 4-5mm below the top of the stem…

    If we’re straight onto

    “Just get new forks mate”

    How about a set of these instead of the Fox 100 (tapered 15mm) compared to these Rebas ?

    Have you got a side on pic, if its a 44mm semi integrated headset the top cup should be flush’ish with the top of the headtube, yours looks like its got a external top cup under the stem,
    From the pics it doesn’t look quite right, maybe…

    You have to forgive me mate, i’m not an expert on headset types/names and descriptions. This is a Hope headset, fits into the recess in the top and bottom on an angled spacer/bearing, with a lower bit beneath and then the crown race (on top of steerer) The top is the same in reverse lol

    I think you’re screwed… Sorry. 🙁 the other pics look like there’s more under the stem,

    There should be a couple of 30mm stack stems out there. Ragley Stubbing is claimed 30mm, so should be bang on the limit of what you can get away with.

    Aah, I’ve only heard it called 30mm, never measured one. A quick google reveals some possibilities, all of them short (in length).

    Ragley stubbing (as predicted above by Warp) seems to be stack height of 30-32 depending on who measured it…. That would put my top of fork steerer 3mm below top of stem….

    We’d be happy with that ?

    Its one thingngetting a low stack stem but your positions non adjustable…and likely will be wrong ?

    Well only slightly yes… I could adjust up or down with higher/flat bars to an extent i guess.

    I’m not completely against buying new forks if that’s my only really sensible option…. However, i’d rather not as it then means selling the Fox’s (which should be fairly simple?)

    I would – it has to be a few mm shy to allow you to tighten enough.

    I’d change the fork rather than fanny around with a headset (and likely setup) you don’t want. PITA though, especially with a new frame waiting.

    Apart from the fork issue, the overall build went… reasonably well.

    As well as ordering the forks, i’ve ordered the Ragley Stubbing stem, i’ll try the stem, see how it fits/looks and make some decisions on the plan from there.

    Sadly my rear brake cable either needs routing along the top tube (which i don’t fancy in all honesty) or replacing with a longer brake hose. It’s about 608″ too short. I could theoretically re-route using some of the CRC cable stick on guides… but, if you’re going to do a job, do it properly i guess. So will get a new hose on there.

    The gearing is sorted, the chainguide is sorted, bars sorted and even the seat is on there and funnily enough my old charge spoon was orange too 🙂 lol. So not all is lost.

    I’ve got a set of Orange Raceface just waiting for me to click the button, but i’ve tied up almost £1000 of paypal funds this week with the frame, mech hanger, forks, bits n bobs.. so the bars will have to remain ugly a while longer.

    Looking in the cold light of day, things don’t seem so terrible 🙂

    Worst case scenario i spend £270 and have a new set of forks on the new frame.
    Best case, the forks go back and the new stem goes on….

    The brake hose i can get sorted fairly easily.. .So it’s just a question of waiting till Monday till the forks and the stem arrive and seeing where we go from there…

    Just wanted to say Thank You really to everyone who contributed.

    Tell us how it rides looking good so far, you won’t be dissapointed with the rebas just be regular with your lower services and the ocasional full strip down. If you not shy with mecainical work I would drop the lowers pre first ride and add some extra lube like slick honey and some heavy weight oil they are a bit shy on the lube from new I think it’s to stop leaking in transit.
