    My futur AM29er

    Hi every body,

    here is my futur 29er frame for enduro race and DH marathon, i imagine the geometry from my riding experience on my niner RIP9, the fork is the new FOX 34 140mm Float factory and rear travel is 130mm.



    I hope it will be a very good weapon ;-)

    Do you know what is new about the 29" rear end?

    That bike is going to rock! I test rode a Helius AC 29er at Nicolai's factory test day and felt rather invincible with it, like you could just cruise over ANY obstacle.

    yes, i want shorter chain stay with clearance for big 29er tires and Nicolaï have to build a new yoke to allow that.

    Looking forward to your new ride Cyril! For what color did you go? Your bronce AC is still my favorite AC.

    Sorry, that was back in 2009 (loooong time ago ). I should have been more precise...

    Edit: This year's factory show will probably be on August 13/14. Don't know if I can make it, but I'll try

    Last update of my futur frame, modification of seat tube to have clearance between tube and tire in maximum compression.

    This is a custom frame, right? Looks good! How much travel will it have?

    off topic:
    I just checked the standard Helius AC29 geo (https://spreadsheets.google.com/pub?...35&output=html) ... that's just STUPID! 72d head angle and 620mm top tube for the largest size...
    It kind of forces one to go custom for 600€extra...

    The head angle is 72° if you use a fork with 526mm height. I assume that's a 100mm travel fork, a longer fork will slacken the head angle. I personally think that the 74° seat angle is (or would be, if you don't use a longer fork) a greater problem, but that depends on personal preferences as well

    What they definitely should change:

    - head tube tapered or 1.5 instead of 1.125in
    - xl size without surcharge
    - higher top tube for l and xl sized frames (otherwise some of us -i.e. me- get problems with the minimum seatpost insert)

    In the end most of us will probably find something they'd change and end up going custom

    mmm my fox f29 80mm is 481mm.

    So 526 would be around 120mm...

    i agree with your other suggestions!

    I'm 6' and on a medium ac 29er. I went for the medium as it's closer to a conventional large than a medium. My mates 6'4" and has ridden it quite a bit with no issues. You'd have to be a bit of a monster to need an xl!

    Only thing I'd change is the ht. I went with cone head but I should have went 1.5 to allow the use of a flush mount top cup to get the stack height down a bit. It would also have allowed me to fit an angle set but without knowing any better I'm happy with the ha as it is(running a 120 float)

    Well, thank you...

    I'm only 1.9m, but my legs are very long. I ride a 865mm saddle height...

    My Current ride is an '07 RM Element, which, frankly is a bit too small for me.

    615 TT: --> OIld skool 130mm stem and EA70 seatpost with massive setback.
    510 ST: --> 400mm seatpost (set just beyond the TT-ST junction), high Fysik saddle, Eggbeaters and 180mm cranks...


    btw: Does Nicolai do 142x12? I don't like Syntace X12, because it's not a quick release.

    Looks good, all except the seat angle. The 68* HA should work sweet and even if you went 20mm shorter fork you'd still be around 69*, but that SA will be well over 75* Maybe if you're your height (guessing under 5'9" with that short an ETT) that it might not make a whole lot of difference, but for me I always need to use a setback post, even with STA of 72*. Anyways, subscribed and interested to see how this turns out compared to Whafes.
    One day your life will flash before your eyes, will it be worth watching??

    You sound just like my mate. He's may be a couple centimeters taller than you and has legs just a bit shorter than a giraffe He's done a lot of miles on my medium and loves it. His own ride is a large AM with slightly longer ST.

    If somebody had told me that the combination of purple and orange ano looked good, I would not have believed it. Actually it does not look good, it looks awesome!

    Have to say that when I saw the initial frame pics I was like WTF because of the colours, but I have to tell you, built it looks absolutely freakin killer, nice job man, really nice.

    Thank's for your comments

    The hubs are Chrisking mango with the front in oversize version.

    I ride it on sunday, and WOW i love it a lot!!!

    Pedaling very good in long way and reactive in acceleration (more than my RIP9 with finaly 147mm of rear travel on the AM), and more stiff at all point frame and fork (the fox 34 is the fork for 29er), the pif paf ride faster and the precision is very very good, the suspension work very very well, i modify the setting of the BOS Vip'R after the first ride to have less progresivity, and put more pressure in the fork.

    The bike is exactly what i want a real Enduro race bike to perform in the Alps.

    I have to improve my setting and ride more to preapare the next season so it's all good

    looking forward to back to back reports of the 29er -vs- your old 26er[s]....

    whats the biggest difference youve noticed ?

    I ride 29er since 1 year, so the biggest difference is :

    1st/ regarding to en 26' bike with 140/150mm, the use of the bike is wider, pedaling like a 120/130mm with a big capacity on loose terrain and descending like a 150mm (or more), so the use of the bike is more wide, means more pleasure to ride!

    2nd/ stability on technical terrain with rolling stones is better

    3rd/ grip in devers

    So wih this new 29er i look for more reactivity and agilty and better capacity in technical big slope, than my old 29er (RIP9) to be close to my Helius AM 26'.

    I have to ride more to answer to this question so i think that the difference is very reduced.

    Yes a lot! there is no comparaison to the Rip9!

    More efficient in pedaling, better accelaration due to the stiffness of the frame and the chain stays shorter.

    Better in downhill (géometrie is better and rear stroke) more agile, stifness of the frame and fork, shorter chain stays.

    Simply better at all point!

    All hands on deck Mr Christian the 29er is faster and has taken over.

    Cyril.

    I have been thinking of something similar but with the 120mm of travel of the AC, 140 forks like AM. I was thinking of keeping the same chainstay length of the AC29 at 463, but with a slacker head angle of maybe 70deg and Angleset. I also wan the bike for Enduro's.

    I seems if you move nearer the usual 447-448 chani stays then the slacker HA, 68 is ok.

    Anyone else have a view on this. Longer stays, steeper HA or shorter stays, slacker HA?

    My ac 29er has the same 460 chain stays but I went for a 68.5 degree ha. I would of wanted to reduce the length of the chain stays however I am having a pinion. Therefore I can not mOve the the seat tube forward to allow the clearence

    For Enduro my géométrie is very very good.

    If you look for an AC29 at 120mm, i think is better to use 68° for enduro use or 69° for allmountain use.

    Finaly my frame have 142mm of travel with 448mm chain stays and seat tube little forward so with 74.5° of angle the pedaling position is excellent.

    So i think that the clearance for the tire is too little and Nicolaï build for me a new swingarm 5mm longer to have more clearance and directmount front derailler.

    in this configuration with 140mm front and rear i can challenge with the best bikes in 160mm in downhill, and the bike pedaling better than a 160mm bike.

    Yes. I only wanted to keep the 120mm rear travel to avoid the modified BB area/moving the seat tube forward and lower the weight. I want to run 140mm forks.

    I think I would propose 453mm chainstay length with a 69deg head angle on a 1.5" headtube with an angleset. This way I can reduce the head angle to 68deg easily but have the option of going a little steeper for more over mountain type events. I think the 74deg seat tube will be good.

    This would be very close to your geometry Cyril but with 120mm or rear travel rather than 140mm, which I hope would be still very good downhill.

    awesome ride !!


    2nd
    just wondering because i contacted nicolai a few months ago about some requests/suggestions to subject matter:
    shorter chainstay
    but they answered "shorter than 460mm isn´t possible ..."

    do you had problems to get your custom made geometry @ nicolai??

    bigthanks

    Thank's

    I have the same answer from Nicolaï so i continu to ask with Nicolaï and they arrive to propose somthink better.

    So 447mm is very short and it's not possible to use tire bigger than 2.25 and Nicolaï don't build my swingarm with direct mount fixation. Then i wait for a new swingarm with direct mount fixation for front derailler and longer +5mm 452mm to have more clearance for the tire.

    Will you be able to fit a 2.4 tyre in Cyril?

    I m really trying to decide if an AC with 120mm rear/140mm front travel will descend as well as my current 160mm Helius AM
    OR whether I have to go to 130/140mm rear with all the changes required to the BB/seat tube area..

    I would prefer the simplicity and weight savings of 120mm rear but don't want to compromise too much on descending..

    pilot - have you ridden an AC 29er with 120mm of rear travel ?

    if not, surely that's the answer, not hypothesising ?

    no not a 2.4 tyre, it's the reason i increse the chain stays, so i think that a 2.25 Ardent is very good, i have a lot of stone and it's not a plroblem with this maxxis tyre.

    I understand what you want :"I m really trying to decide if an AC with 120mm rear/140mm front travel will descend as well as my current 160mm Helius AM"

    I'm in the same deal with may AM 29', it depends of your skill of pilot and what kind of terrain do you ride, do ride your AM 160mm like a DH bike? (or very close) If it's the case I think you have to choice 130mm rear, with 68° of head angle or 67.5°.

    I have aslo receive a Banshee Prime with 130mm and i can compare both frame, for exemple the frame of the Prime is heavyer than Nicolaï frame, so both bikes pedaling very well and are very close.

    when you have 453 chain stays will that fit a 2.35/2.4 tyre.

    Yes, I ride in the Italian SuperEnduro series and events like Trans Provence so similar terrain as in your video. I is important to have good DH capability but good pedalling too.

    A DH bike that can pedal, not a XC bike that can descend!


    I would say my skill is ok, but I need all the help I can get...it sounds like a max 140 travel could be better.

    I like a very short stem, 50mm, my current AM is a med with 585 TT and it's too short really, I have to use a layback post and saddle at the back which affects the climbing/pedalling so I want to have a 610mm TT


    I have also receive a Banshee Prime with 130mm and i can compare both frame, for example the frame of the Prime is heavier than Nicolaï frame, so both bikes pedaling very well and are very

    I think I now have a good idea of what I want, I'll go from Cyrils drawings and mark up some mods I think to get my head straight.

    Only question is whether to go with an AC with a naughty fork whilst waiting....Med AM and BOS Devilles anyone... ;-)

    With 453mm CS I think 2.35 will be good so it depend on Tyre and Rim, NoTube the volume of tyre increase for exemple.

    I run a 35mm stem, you will try it ;-), "good DH capability but good pedalling too" in this case you can run a 130mm with a geometry close to mine based on AC tubing to have a lighter frame.

    Last year i run in endur series with a RIP9 it's more like a XC bike that can descend.

    Cyril,

    How do you compare your Nicolai to your Prime in riding? IS the Banshee as stiff as the Nicolai?

    Got a definite answer from Nicolai today on 29er chainstays length with their suspension design.

    As posted earlier with 120mm travel 460mm is the minimum length. Any shorter does require the modification to the seat tube position like the afr/ion as Cyril's and Whafes.

    TI would seem if you make that modification you may as well go to 130mm -140mm! The yoke will take a 2.4 tyre, but the clearance between tyre and seat tube might be tight beyond 130mm as Cyril describes.

    Cyril do you have your new Swingarm with direct mount front mech yet?

    The geometry will be very similar to your Prime then? Perhaps slightly longer chainstays on the Nicolai, 3mm or so?

    Compare to the Prime Stiffness is similar, the prime is quite more stiff so there is no différence in riding conditions.

    I have not my swingarm yet, yes the géométrie is quit similar on both an sensation are very close, for the moment swingarm have the same lenght, so after correction on swing arm it will be longer and a bit lower and slacker.

    How long are the stays in the end Cyril? Mine will be 454mm.

    Having spent some time on the standard bike now, I'm looking forward to the custom. I found the standard bike pretty agile, though much of that due to the head angle I think. The frame is impressively stiff.

    I was looking for over one year to find another Helius AM 29er.

    I have the same swingarm. If you add a 222x70 damper you can generate 170mm travle on the AM 29er (there is enough space between seat tube and tire)

    Very very good, the front derailler direct mount work very well and clearance is OK with a big tire.

    Did you say the prime was more arid Cyril? It's heavier I think than the Nicolai?

    Is the cable route to the rear dérailleur the same as a 'normal' Helius?

    Yes the prime is heavier, so the suspension work very good in downhill sensitive and progressive, (better than the Rune in 26') so the Nicolaï is better in rought terrain and better in pedalling.

    The cable route is to same so the cable stop is on the swingarn not on the bottom bracket.

    Cyril... tell me more about the CR Conception cartridge.

    It's the only decent damper for a Revelation on the market. Well, there's Push, but they don't touch the compression side.

    That would turn my Revelation into an Open bath-coil spring fork... sweet.
