    nice spec, good call on the goodridge black hoses, i did that on my gspot and the difference was big. For some reason i though you went with red black and green. hopefully with white it wont be so bad lol.

    Hiya Ian

    Are you sitting comfortably? Yeap you are correct however. Originally I wanted a cow colour bike, mat black, gloss black and gloss white but Nicolai couldn’t do the mix of gloss and mat! So I went for black, red and white but changed my mind to black, red and green. Whilst on holiday I did a cut out frame and coloured it in and the black, red and green did not work as well as the black, red and white. Thanks to the guys at Nicolai UK I was able to change the colour at the last minute. I’ll see what turns up

    Okay I have it now and it is brilliant. Believe it or not it is way better than the CC!!! This bike is so responsive it turns on a dime, it is smooth, fast and just bloody amazing. I love it soooooooooo much already. I honestly can't understand why eveyone doesn't have a Nicolai! So what do you think

    After 3 ride session i can said that the rear suspension work very well, with the DT swiss shock (55mm ->155mm rear wheel) you can tune the shock with 35% of sag, pedaling is still excellent and you can descend very fast even in rocky terrain.

    Just a little precission with this shock the tire touch the seat tube in maximum compression, but it'is very difficult to put it at it's end.

    If your are not a freerider, the Helius AC is the ultimate mountain bike, if you want to keep just one bike take the AC.

    For me it's not a problem, i have an FR before, and i have never problem with that yes the tire touch the seat tube (no sensation of it when you ride) but it's a compromise to have short chain stays seat tube ange correct and fixed on bottom bracket, if you change somthing to correct this, the bike will be different than tne FR you like.

    And the AC like this is very fun bike agilty, speed with very good suspension and a particular skill to pedal efficiently... so no problemo...

    I just notice that because i saw a topic for the FR where it seem to put a problem for someone, on AC you put a Monarch like nicolaï website and it's ok.

    yes he work great and with the dtswiss it's very close to an AM (157mmAC 160mmAM)

    if you are a 70kgs weight with a clean riding style, you can put a 160mm fork and ride as fast as a 160mm frame in DH marathon or enduro

    @ Mugtree and Cyril

    How do you like the climbing abilities with your fixed travel forks ? Does the front wheels rise early ? Since you both run a few spacers too, I was wondering ...

    for my point of view the climbing abilities is excelent, then my frame is a tailor with HA at 67° for 530mm fork, the other lenght are standard.

    my legs give up before the climbing performance of the frame.

    hi cyril,m

    i just sold my AM for AC , but was worried about the endless travel feeling i had on my AM when its was with the EXC 150mm front fork and rear marzocchi roco air with 57mm stroke places at 150mm travel on the rear.

    as per in my comfrimation with Nicolai they recomman a DT swiss with 50mm strok rear shock. meaning i will only get max 146mm travel... is the tire touching very bad on the frame as i would very much like a longer rear stroke, i,e, 55mm as my last rear shoc was 57mm?? And sad to say, i do set my shock relatively plush with between 28-30% sag...

    w want the AC to do the job of my AM back then

    I don't understand very well all that you said, but :

    1/ you must mount a shock with maximum 55mm (dt swiss xm180) provide around 155mm of ravel and some time in maximum compression tire touch seat tube, then nicolai recommande 51mm strocke for shock, i use dt swiss with 35% of sag (my wheigt 70kgs) and i never use maximum compression.

    2/ 57mm strock is too much

    My feeling is that the rear shock is very progressive, the travel used is always 90% then you have to do drop upper than 1 meter to use maximum strocke.

    So my setting is good for me and my trail with a lot of rocks and dry terrain.

    No, but nicolaï can provide this one (dt swiss xm180) and i recommande you to do that because the shock axle is exactly the good one (i have some trouble to have the right one with dtswiss)

    i can deal DT here but they don stock up, i have to order them , i ordered some ex200s, with 55mm stroke. Nicolai recommanded 200mm by 50mm when i ask for XR carbon. Although XR carbon does come witha 200x55 thought,,, not sure if i shall go for it like you do

    Hiya Testmaen.

    I've just got back from a couple of weeks in the Alps where I spent way to much time going up hill. Saying that though the bike climbs beautifully, even on the really steep stuff it was easy to keep the front wheel down. I tented to loose traction before anything else.

    Hope this helps?

    How tall is the BB on an AC??

    I've found the BB drop on Nicolai's page and that gives me a rough calculation of 346mm with a 520mm A2C Pike... That's 13.65" (approx) for those metric challenged.

    But that's theory over a bike unseen... how about real life ones?

    Just guessing as the 13.7 felt really good on my Switchblade with the same fork, but the AC would ride slacker at the front and steeper at the back, which will be nicer.

    Any help is appreciated!

    Hey Mugtree,

    thanks for your reply! How do you like the AC compared to your previous CC ? A lot of difference ? From your pictures i cannot spot a lot of differences in the build...

    Good to hear that it climbed so well in the Alps. Was wondering since you're riding it with a setback post and the some spacer and (what looks like?!) a short stem.

    Did you choose the coil and Rohloff setup mainly for reliability reasons ? Not that they aren't good gear, they're excellent, but you don't see them very often combined on a bike in that class.

    More questions...

    Is the 22mm deep headset insertion rule applicable to the AC? It says so on the pdf at Nicolai's page. Is that dependent on the fork used? Better put, strictly needed for a RS Pike?

    I'd hate to dump my CK... but then frame's integrity is better than bling.

    Now, reducers for the shock... 24 X 6 and 49 X 8??? Is that correct?

    BTW... the bike pictured on NIcolai's site has a Fox (Vanilla 150mm??) which is more or less same Axle to Crown as a Pike and it has a normal headset. The CC can run a max fork of 520mm A2C and also runs a normal headset.

    Mugtree... did you asked Nicolai or your dealer when deciding on the CK headset??

    Sorry for that many questions...

    Would the spacers not be both 8mm for a shock?

    Not necessarily... My Switchblade uses 49 X 8 and 30 X 6. The front eyelet sees more or less the same force as the rear one, but much less twisting. That is the size of the bolt used and a 6mm bolt is enough.

    That said, I'd prefer them both 8mm, but 6 for the front does just fine on a bike like this.

    I'm asking if the sizes are correct...

    all that you said is correct, so a 150mm forck is more 530mm not 520mm as a pike.

    for headset i us acros ah07

    Warp - You would be fine with the CK Headset you have on the SB...

    When my Healius AC 29er arrives, I will be running a CK headset.

    I think the 22mm headset is a suggestion not a must have, only downside would be if the warranty is voided, but the chances of ovalisation on a Nicolai are slim due to the build quality!

    Would the AC pedal ALOT better than say a nonius?

    I'm also looking for a trail bike and fancied the nonius but i'd like it to pedal well.

    Me too derek , but i reckon i'll be getting a 29er hardtail for racing ! It would be nice to splash a bucket load of loot on say similar to whafes secret bling number, but i have too many other interests that involve bucket loads of cash forgive me for being blasphemous but im getting quite settled on a Vassago Bandersnatch (sounds crap) but i only need it for <5% riding, its a steel hardtail 29er with a slack geo. I absolutely love my AM and it will be #1 for a long long time so dont want to have another mega buck bike sitting there doing nothing , i already bought a expensive carbon race bike and sold it after 3 rides so i know what use the 29er will get

    Yeah

    Well now i'm getting the AFR (Perfect mega avalanche bike) i really need a smaller bike for trail riding and i love the look of the nonius and its quite cheap but the problem is i have no idea if it'll pedal well being a single pivot! The AC is big money compared so its a hard one
