    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.

    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

    Bit off-topic here under AC-setup database- tread, but...

    Just got new AC-frame yesterday and noticed one small difference - there are two oval
    holes placed in chain stays / lower links on all pictures available here and in tech specs diagrams too. But in my new frame there´s only one - that in chain stay, lower linker is
    without that hole. Only wondering why - may there be other small constructial changes done too? This frame is the first one here (maybe) and cannot compare to others - except images...

    Any inside-information? These missing holes there (one in each side) are not an issue for me ... can live with this

    Sorry, not pictures / specs yet - coming as soon as we`ve here light enought for taking pictures

    Did you ordered any custom geo? That'd be some explanation as your rear tyre looks closer to the seat tube also. The rectangular chainstays look closer to the machined yoke.

    I think it's just that.. the rectangular stay looks ending slightly forwards if compared to Mugtree's. I measured comparing the size of the brake line guide. On yours is slightly greater than two lengths and on Mugtree's is more like two and a half. It could be just the perspective of the picture and a mental jerk off of mine.

    If anything, your rear end will be heavier, but stiffer... look for any probable interference just for kicks (tyre hitting seat tube, FD, etc.).

    I'm intrigued also...

    Comparison pic... if you don't mind, Mugtree...

    @warp - geometry should be the standard one, frame size is M without any other mods than ISCG mounts ...
    Noticed too that mine rear tyre seems to be closer to the seat tube than Mugtree`s nice coloured example shows, my tyre is Fat Albert 2.4 UST, which is BIG compared to Mugtree´s Maxxis Ignitor(?)

    I was positively surprised about tyre clearance in rear; geo specs claim that in AM there´s
    clearance enough for 2.5 and in AC for 2.4. That FA 2.4 is big, but tried Conti`s RubberQueen 2.4 too with nice results - no problem. And RQ2.4 is huge - there are slimmer DH-tyres at 2.4 - 2.7 category

    Anyway - have had only few hours to test AC yet on local trails and so far so good - frame with DTSwiss EXC150 in front and EX200 / 55 in rear seems to work smoothly

    Look closely at the rims... I know tyres could deceive.

    Good news on tyre clearance... keep them coming. More pic are welcome.

    @ cyril_88

    thats still the best looking Nicolai I've ever seen from a pure aesthetic perspective.
    i couldnt live with the fragility of the PACE, sorry, DT forks though.
    how are they holding up in the ALPS ?

    Interesting that cyril_88, Mugtree & pergamonx all have Medium Helius AC's and that as pergamonx mentions, his is the only one with the one hole on the rear stay, also from the info, all are standard medium frames, no custom stuff....

    I too am perplexed....

    Granted, that's a 12mm rear.

    What gives? Just curious... I'm actually more fond of the one without the second hole. Stronger for a few grs.

    I'm wondering too. But I think you can spot the 2nd hole on the right chainstay. Quite hard to spot anything with the dizzy-tiger-camou, or whatever the he** that colour is called.

    @Warp - I second; I personally prefer chainstay without (additional) hole - maybe more stronger, don`t be sure about that - and adds bit more weight ... but still - at least one place less to dig when cleaning up mud etc

    As said earlier - question about this missing hole was actually question for other possible changes / variations in 2010 AC frame - I`m mostly interested are there other changes in rear frame and if there are - why?? Simplier to build / some estimated weaknesses / what ever ...

    Geometry fits at least for me / my poor driving style perfectly - still waiting some parts - new stem, handlebar with bit higher rise and thicker lock-grips fitting better with grippers ... maybe next week it`s ready for presentation with some pics.

    You know I am sure I've seen the same thing on a Helius AM. I was comparing an AM with an AC in HFTH last week, trying to see what the specific tubing differences were and one of the things I noticed is that the AM had solid chainstays like the ones in peramox's picture while the AC had two holes.

    It's possible that Nicolai have slightly revised the design of chainstays recently. This happened with the Ion ST which had some subtle differences in design between the earlier and later models.

    When my AM turns up later this year, we can check again.

    @geetee1972 -

    tried to compare to AM´s too, but all those (two) AM-frames were older (2008?) production and they both have 2 holes - but I still believe that you`re right; there are changes done in both frames and newer ones does have those solid stays. There are not very many frames available for closer looking here in Finland, our market is so limited But big thumb for our local LBS here selling Nicolai - it`s not his fault that there are not more Nicolai`s here - I´ll give five stars for service!

    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.
    Hiya Testmaen

    Sorry for taking a while to get back to you. Right CC compared to the AC. If I’d replied when you posted this I’d have said the CC was better but after Saturday I kind had an epiphany and everything made sense. I’ll try and explain. My CC was perfect and if it had not been stolen would never have been replaced, but **** happens and it was stolen. I got the AC because for the type of riding I enjoy I was told the AC would be better. In the Alps I had a fantastic holiday but something wasn’t right and I couldn’t put my finger on it. I was un-fit after 3 months off the bike so that did not help but the bike didn’t feel right. Yes it climbed better than the CC, it went down faster and better than the CC, it did the tight switch backs better than the CC but I still preferred the CC? After getting home I played with the set-up some more and finally got it right. I’ve ridden a lot too since getting home and on Wednesday and Saturday last week it all came together. I think what was wrong was partly the set-up being slightly off but mainly my head. It had been three months without a proper bike and in that time the CC had gone form a bloody good bike to perfect with no flaws, I believe it could actually fly too so all the AC could do was not be the CC, being new too every thing was tight and need wearing in. On Saturday I finally realised how good the AC is when I did the Lean Back and the Kinicker trail. Two trails I could do on the CC but with difficulty. The AC just laughed and made the whole thing look easy and they were wet!! So I finally realise the CC was not perfect, it did not climb better than the AC or come down better, but I do know the AC goes round corners and damn sight better and on fast rocky descents just floats.

    Why springs and a Rohloff? Yeap reliability. I only weigh 55/60 kgs but seam to break air as if it is made of paper so springs work and I love the plushness. As for the Rohloff same. As I use this bike everyday the chain, chain rings and cassette just died each month so the ‘hoff is a cheaper option, works in the mud (my fav surface) and it maintenance free. This is my second one and I’ll never go back to normal gears – ever.

    As for the spacer, short steam and set back seat post. Spacers for my bad back, can’t be too hunched, short steam for quick responsive steering and setback seat post to fit the bike, I seem to have a longish upper body.

    Hope all this helps?

    Warp no worries about using the pic, just wish the bike was still that clean

    400g less than the AMs I guess, i.e. the difference between the frame weights.

    Very nice perg; i'm a little confused where the AC sits in the grand scheme of things as there so little weight difference between it and the AM plus the fact the AM can also run @ 140mm, be nice if Nicolai could define some limits so we know how capable each model is. If i'm gona order a trail only bike i;d expect sub 30lbs really (Altho i dont really care about weight) so would be interesting to know whats what.

    @norcosam - so far DT Swiss fork / shock has been even better than expected - first time trying those, not many more here in my neighborhood
    Took 30 mins to find suitable adjustments to both of them and now, after maybe 25 driving hours fully satisfied. They`re super-smooth and works fine everywhere I´ve ridden. Like the suspension curve - in the beginning soft and fast, after that nicely progressive ... feels like suspension is bottomless..
    Few friends with more experiences `bout different forks /shocks have tried mine and general comment has been "amazing" - my old combination was Fox Float 32 RLC-08 (120mm) and RPL23-08 and definately these new ones works better.
    On the longer run - don`t know. Know the history of DT Swiss suspension products and reputation of Pace forks ... reliability is still not-known, there`s no that kind of experience enough. But I´m happy with those thingies so far they does work

    ...still back to those dampers
    Lightness was not the reason why I took those DT Swiss- fork / shock (I`m not a weight weenie - measured my bike only because everyone asked the weight and I got tired to answer don`t actually know...), main reason was to get an experience - there are many thinking those, but one very few have used those.
    There was quite nice alternatives, from tuned Wotan to 2010 Talas ... but you drive with only
    one fork at a time
    About the same with shock - I know that EX200 / 200mm - 55 mm is bit against Nic`s recommendations and therefore I don`t use the top hole, but the second. I´m also thinking at least test some nice coil-shock for wintertime usage, there are quite many testing shocks available from my friends - let`s see ...
    Overall-performance with this combination has been surprising, (I´m still bit careful with my judgement, because there´s still only <30 hours of testing done) but with my old rig there were situations in every drive that when I failed to do something, I knew that at least one small part of reason was behaviour of suspension, not only my poor driving skills. But with this new one, those earlier so challenging sections are piece of cake to drive and - I still fail sometimes - there`s no need to claim bike, only lack of my skills
    So, my conclusion is simple - in my case, new bike has helped me to drive more better...

    It was my plan to get quite up-right stance building quite short cockpit, because I use most of my time with tricky technical sections, not rolling very fast on open singletracks. With short stem and high-rise bar it`s now perfect in my taste ... It`s still nimble enought, fully comparable in that meaning with my old GF Hifi Pro, even bit better. It`s nice climber too,
    rear end does not bob at all and only limit when climbling is grip of rear tyre and what has maybe been the biggest surprise, is the balance even in steepest uphills, the front end is not aiming to the sky - even without lowering the fork... In other words, it`s easy to keep my balance in most efficinent place. Also when pedalling with force in easy trails or in roads, I`ve not even thought the need of any kind of locking options to dampers.

    Of course there are few things still I´m not yet fully familiar ... handlebar is 20 mm wider than older and fingers have got too many hits from trees (we`ve here a lot of narrow paths..) and there`s need to get more lay-back to seat post ... but it`s very very near the rig I wanted.

    @T_L_R - approx one / every 5 mins - but those ones are because my incompetence - much less compared to my old rig - like the higher BB

    Actually I tried Truvative Stylo cranks (black ano) few days and noticed that they were not really black anymore - one more reason to use plain silver / alu cranks ... Bigger reason for changing (back) to XT-cranks was incompability issue with Hope BB, Truvativ adapters does not work with Hope - there`s no way to tighten cranks enought.

    seems pedal strike is now more common as a consequence of improve "all-mountain" handling.......?

    @T_L_R - yes and no -

    higher BB means less strikes in same lines, easier capability to steer over the rocks instead of trying to steer_between means less strikes, more difficult lines / "can I do that`s" means more ... maybe net is `bout the zero

    FYI:

    Falco said in a thread in the German Nicolai forum on a tire-seattube-rubbing-issue, that the max. travel of 146mm is achieved with the shock mounted in the 2nd hole from the top with a 50,8mm stroke shock. The top position can't be used.

    hi test..

    any issue if you were to use a 55mm stroke rear shock?, like one of the guys here and claim to have a 155mm travel at 2nd hole on a helius AC ?

    I don't know, I'm neither a AC owner, nor Nicolai.

    I could imagine however, that a 55mm shock could work without collision in the 3rd hole. But make sure, make a collision test either way.

    I´ve shock with 55mm strike mounted to second top hole without rubbing problems. Nice guy in LBS adviced not to use top hole with 55mm strike.... anyway- got psi`s out from shock when similating bottoming and with 2nd top hole no clearance problems (tyre was RQ2.2)
