    Got My Niner Carbon Fork Installed!

    Got my Niner Carbon fork installed Saturday. I just want to say thanks to the guys at Carrollwood Bike Emporium for doing a great job as usual. They really are a cut above the rest. Chad and Brian are the men. I haven't given it a legit ride yet but when I do I'll be sure to post my thoughts about it. It sure does look pretty though.

    Nice...what are your trails like? Rigid can really beat you up.

    I live in FL so I don't have to many rocky/rough trails. We have a lot of fast singletrack. The biggest obstacle I have is pine cones at Croom. From what I have ridden today I wouldn't trade it in for the world. I love it so far.

    FYI, Niner does not recommend putting headset spacers above the stem because the stem clamp may crush the steerer tube. Great looking rig.

    I heard that but I have seen a lot of people run a spacer above the stem. Even the Niner team uses a spacer so I figured it should be okay. Niner said you can run maximum 40mm spacers under the stem which I think is far worse than me running what I have.

    Depends where you set the compression plug. If it's low enough you can run spacers above or below. They (Niner) simply want to be certain that the stem clamps the compression plug so there's less chance that it'll slip.

    ya, there's these...instructions...FWIW...funny that u say Niner is do-as-I-say-not-as-I-do...
    http://ninerbikes.com/downloadfly.as...t_RevOct09.pdf

    Although I'm running a 5mm above my stem but that metal plate on top of the plug is only 1mm above stemline. I almost commented looked from the pic like you have a 10mm or so spacer hard to tell. I needed to buy a torque wrench finally...mine is my first carbon part...loosened up once already, I hate running to a shop repeatedly. It is a little finnicky on the creakiness but it rides like a dream. Enjoy! Nice looking bike, Phil...

    I'm only running a 5mm spacer above. Now you guys got me worried. I think I'm gonna cut it so I don't screw it up.

    Hmm...my shop used this thing that was like a saw to cut the steerer but instead of teeth it had sandpaper. If you are within a mm or 2 I would not sweat it, just get yerself a torque wrench for when it makes noise and the headset needs a tightening. You're more likely to mess it up by re-cutting it, unless you are experienced with carbon. (I'm not, hence the shop doing mine.)

    I got the park tool "beam" style torque wrench (not the expensive clicky one)...it is totally adequate. My shop had the fancy saw, but they did not read the instructions either, esp the part where they say to tighten the plug to 7nm...mine slipped after a couple days, so I cranked it tentatively to 6.5mm... solid since.

    My experience with full monocoque carbon forks (Edge Composites Road 2.0) is to have a 5mm spacer above the stem, minimum. Ideally, 10 mm below the stem, maximum. This is directly against what "MrXC" is saying and what he claims Niner states. The compression plug takes care of any "crushing". The spacer above stem makes sense as you wouldnt want a stem to skew pinch pressure point the carbon steerer tube.

    p.s. a torque wrench is highly recommended - the Ritchey 5nm one works great, I dont even let it click. Also, a couple shops recommend carbon prep paste for carbon forks, stems, seatposts to prevent slippage due to strict torque numbers.

    Now all you need is a white seat post to match that sweet fork.

    Looks good.

    Ritchey recommends putting a spacer above the stem (as shown in the OPs pic) on their carbon steerer tube road forks. The compression plug is 20+mm so a 2-3mm spacer won't hurt anything.

    I checked my top spacer above the stem and it was 10mm. I took it off and loosened the stem bolts. Its going back to the shop Wednesday to get it cut down so there are no more spacers above the stem.

    In my pea brain, clamping a tube below the edge seems like it would be stronger than clamping it right at the edge. What am I missing?

    The compression spring that goes in the steerer tube is not that long. If you run spacers above the stem you are clamping the steerer tube below the compression spring and you might crush the steerer tube.

    I had a G2 Fox before. The geometry did change a little but for the most part I actually like it better to be honest.

    nice bike phil...love the set up.

    i love the carbon niner fork....rides great, seems tough, looks like sex and crazy light.

    here is a shot of my bike with a similar set up (niner fork, 1x10 set up with a e13 xcx).

    Where the heck do you ride at Croom? It's all sand-whooped out doubletrack that I saw, and a singletrack enduro loop that doesn't look too mtb-friendly in my estimation. I've often WANTED to ride MTB at Croom, but saw no realistic options... I do have fun on a moto bike though.

    I think mine was 558 g. with the steerer cut to 8 inches with the headset race installed. And with the compression plug it was like 620 g.

    I agree. I would like to powder coat my bike when I get a little extra cash but it will void the warranty on the frame.

    It weighed in a 21.4lbs at the shop after we installed it. There are a couple more changes coming as well. I would def say it's quicker in my opinion. You can feel the difference in the front of the bike. To me it feels like it steers more precise. The biggest difference to me was going over bumps. It absorbs a lot. I had a steel fork a couple of years ago and you can notice the difference between the two.

    are you sure you have that right? Most companies that make a recommendation about spacers above the stem tell you to put them their. That way the entire stack of the stem is clamping around the steer tube and you don't get the top of the stem closing down. I've never heard of a company recommending against putting a spacer on top of the stem, but then I don't know everything

    Crazy as it sounds thats what Niner says. They say to leave a 2mm gap from the top of the steerertube to the top of the stem. They want the stem to completely clamp the compression plug and not a hollow part of the steerer tube because it could crush it.

    Not to argue, but I don't buy that. The star nut isn't going to prevent you from crushing anything...you can flex it with your fingers. The bolt pulling it upwards strengthens it obviously, but if the steerer tube is thin enough that that is what is giving it strength, what's keeping it from bending due to impact forces at the lower bearing near the fork crown?

    The fork has a carbon steerer tube and uses a compression plug (expanding plug if you will) in lieu of a star nut (used on alloy steerer tubes).

    Compression plugs are typically about 20mm long (or more). The purpose behind a 2-3mm spacer above the stem is to ensure the stem clamp is fully clamping the carbon steerer tube, no leaving a gap like you do on the alloy steerer tube to take up slack and pre-load the headset bearings. (FYI< you can't use pinch type clamps, i.e. Thomson Elite style, Thomson X4 or X2 road is OK).

    Wouldn't the shorter/less offset of the Niner fork make the steering a little slower, more stable? I could be completely wrong of course. I am sure it feels more precise.

    anyone got a pic of niners carbon steerer plug? i have a road edge fork, and the edge plug can be set at any height in the steerer (within sensible limits!) and you would just use a longer bolt, keeping a bit of adjustability there....

    ... and if we just ... A New Classic- Engin + Niner Carbon Fork

    Well-----i REALLY like the way my new fork looks on the bike. It looks better in person! It makes the panels on the paint pop! I also like the classic HT geometry with the mod fork style. Boy was it light out of the box. Rode it this am. A tad stiffer than the WB Rock Solid it replaced. No complaints at all.

    I don't have a pic. but FSA makes it and I'm sure any brand would work as long as you set it up right. I actually had problems with the one that Niner sent. Fork kept getting lose so I tried a different plug(also FSA) and it worked better.

    replying to my own message here with an installation and ride report.

    Install was a cinch. Fist thing in noticed was a small weight loss on the bike. It was a tad lighter with the all carbon setup coming from the WB rock solid. Have 2 rides on it this weekend. first impressions- the steering is more precise and a bit faster than the wb. the placement of the wheel makes a difference. the ride is a bit stiffer in the front as well. descending was interestingly a bit more agressive on the niner and i had to watch my line a bit more carefully than previously. its been dry as hell here in pa for months do the ground is either dusty or hardpack....played with tire psi to reduce ride chatter and all around very nice rides. Ill play with the tires a bit- i ride a 2.4 conti mtn king.

    Second update
    I have ridden the fork 5 times. Def. stiffer than the WB rock solid. The funny thing I have noticed is that the fork is more responsive- direct small steering changes. The other thing i noticed is something i dont like- it feels like I have to pull up MORE on the niner to get over logs. Im a dummy- is the rake different? length of legs? This is really annoying.

    third update- ridden 8 times.

    dredging this one up again...

    got a niner fork to use, and for the sake of adjustments in the future i am keen to run some (not many) spacers above the stem.

    niners instructions are clear, no spacers above so the stem clamps the area that is reinforced by the compression plug: am i right in thinking that the niner/FSA plug is quite short?

    has anyone tried using a longer carbon steerer compression plug such as the PRO 50mm one? or the prolite one?

    im thinking that might allow a little more adjustment, *but* the design does seem different - maybe not as reinforcing?

    however there is also a deda version that looks to be a similar idea?

    thoughts?

    Love the Niner carbon fork... thee best rigid fork made.

    I ended up putting a vinyl wrap on mine to cover the blingy logo stuff. Tore right off with no residue when I went to sell it.
