I have a Giant Carbon Fork and steerer (attached to a 2011 Giant SLR Advance SL Frameset) does anybody have the piece of paper / manual that descripes installation of that fork / bung, I am mainly interested in the fitting instruction of the bung ... local bike shop lost mine and not been able to find it on the Giant site

Thanks in advance

Chris

  • Hi

    Thanks ... but I was actually looking for the Giant Specific ones, the Trek and Specialized ones are very specific about no of spacers above stem, expander and stem interfacing (again very specific in the Trek and Specialized manuals) and see what Giant recommended

    Thanks though

    try calling giant uk 0844 245 90 30

    otherwise, cut steerer to be no more than 2-3 mm below top of stem

    install bung, it should extend from top of steerer to below the area clamped by the stem

    if the top cap fouls on the top of the bung, add a 3mm spacer above the stem

    imho spesh's admonition about no spacers above the stem is simply to avoid putting the bung so high that it no longer extends beyond the clamped area, and also to avoid creating a small, blunt, spear sticking up above the stem

    generally carbon steerers are cut about 5mm above the sten and then as spacer is fitted to give the preload gap.

    nothing to it.

  • Interesting .. two people, two different answers. The Trek recommendation is that you cut 3 mm above and use a spacer, the specialized recommendation is that you cut 3mm bellow and use no spacers .... just trying to work out what Giant say. I wouldn't be to worried about 5mm of steerer above the stem acting as a speer

    yeah, it reflects the manufacturers' diverse instructions

    tbh i think both methods will be fine, the only time i'd get nervous about the 2-3mm below is where the stem clamp is very low profile, then i'd go for a few mm above, otherwise it'd feel like there wasn't enough steerer in the clamp! on mine, i've swapped stems with varying depths, some needed a small spacer on top, some didn't

    see if you can get a response out of giant, they don't seem to publish much online, so if you can get a useful answer, post it here so it can be found with a search in future!
