    FAO All Helius FR Owners (Karve/007 especially!)

    Hey guys,

    I know you both have similar tailored frames to me with small seattube, medium top tube etc.

    Have you tested full compression of your shock 57mm stroke in the bottom hole?

    Mine has NO tyre/seattube clearance!!!!

    I've sent an email to Nicolai Germany and Nicolai UK but no response as yet!

    Any infoz appreciated!

    I'm going riding this weekend on the bike and if Nicolai dont get back to me i hold them 100% responsible for any damage caused and will expect it repaired under warranty.

    Cheers

    Derek

    I know, that's the only problem. Max you can have a 2,35 but still it will lick a bit the seat tube. it's no big deal if you put some tape on ur seat tube.

    I usually run a Michelin DH24 in 2.2. It's heavy duty and it doesn't touch the seat tube at all.

    If you want to be able to run a 2,5 for exemple, you would need to ask for a longer chain stay, so this way it would pass easilly.

    I wanted really short chainstay, 428, so I knew I wouldn't be able to fit big tires...

    Thanks for the reply 007,

    Hmm, just no one told me this and it states on the data sheet 2.6" tyres are usable.

    Have you actually tested yours? and do you run a 57mm stroke shock?

    Specs

    Acording to my drawing the chainstays are 433 which is 5mm longer than yours so in theory your clearance is worse?

    ya, I ride on 57mm stroke and your right, my tire clearence is even worse than yours.

    But it does pass with no problem with a Michelin DH24 in 2.2

    That's the only real tire that can fit and still be a sturdy tire.

    Might want to check out the Maxxis in 2.35. I used them too. It's touching a bit, but no big deal.

    This way I have a brake while bottoming ! I've check on videos, it's touching only if you bottom out and for a 10th of a sec, and a tire is soft, it's not like if it was a piece of metal.

    as long as you protect ur tube, it's ok. I'll try to take picture of the traces I have on my frame, it's very small.

    This one is the same as your's just size medium with head angle at 66.5°

    and the tire let just a little black trace with maxxis 2.35.



    I know it before my order and it's really not a problem during your ride, you never feel something even in maximum compression.

    Do you mean that 2.35" is a XC tire?

    I'am not sure to understand so freeride bike use commonly 2.5" and there is no difference with clearance regarding a 2.35" because 2.5" is more wide but not high.

    So equipement on dereck bike is more like an big enduro bike and not freeride bike, it's the reason that 2.35" is more usefull for enduro.

    for an freeride use, a coil spring shock is needed.

    (i'am french so excuse my english)

    cyril - you are mis-informed :
    a 2.5" tyre is not only wider but also taller than the equivalent 2.35" tyre.

    I agree with Cyril, I know people mostly think "Helius FR" big tires.... that's wrong.
    Before the AM, the FR was design as a big enduro frame. Try to pedal with a 2.5 on the rear. You won't go far and you can forget to race.

    From there, they decided to shorten the seatstay and minimize the tire clearence.

    It's a choice, some people might not like it. Here in France, the FR is one of the most sold bike of the Nicolai range and nobody made noise about that.

    I'm agree with you and i know that but it depends a lot of the rim dimension and with a wide rim the differnce is very little and not significant to make a problem on FR.

    I use it with 2.5" maxxis without any problem.

    Cyril, on dit I agree, pas de 'm
    mais je suis d'accord, y a pas bcp de différence entre un 2.35 et un 2.5

    qu'ils essayent de faire une Enduro Series avec un 2.5 à l'arrière !
    in english: try to race any enduro race in France with a 2.5 tire !!! sure not to make the podium !

    Thank' seven for your english lesson

    so about tires I prefer to ride with a high roller 2.35DH instead of a schwable big betty (or other) in 2.5, if some one is sceptic i propose to make a test at the MEGAVALANCHE of alp'huez it's a perfect program for an helius FR. (i'm already register for 2009 race )

    so, let me get this straight, you didn't buy a bike that had been developed by those experts at Nicolai,
    you chose to come up with your own design (after all how hard could it be?) and surprisingly it don't work!
    there's another post on here and you seem chuffed to bits we your bike?.
    >>
    You can’t go blaming Nicolai for your inability to design a bike... if they had designed it, and it hadn't worked then you could slag them off.... >>
    >>
    Still it'll make a nice ornament for you kitchen... >>

    Feel the noise...

    It is a good point, however he didn't design the bike, he evolved it, in my eyes it's still nicolais job to ensure that even though the angles have changed, there is still enough clearence for the rear wheel under full compression with a large tire. Or at least inform derkr about the issue so he can make an informed decision, so he can choose between a large tire, or a short chainstay. After all nicolai are the specialists

    don't be so rude funkmonkey3!!!

    all FR have no clearance between tire and seat tube, it's design to keep a good pedaling
    position (it mean seat tube angle not to much tilt) and shorter chain stays as it's possible to have agility and good pedaling response.
    Then it's the main quality of the FR plus a very good supension to keep grip.

    His frame have no problem, the only one problem is that he is not inform before ordering his frame.

    so it's a very nice bike with good components.

    my recommandation for him is :
    give up this forum!!! it's never too late to go for a ride ;-) and anjoy youself!!!

    These comments are not only irrelevant, but negative and unhelpful. Perhaps these they should be directed to a more suitable forum for unhelpful people.

    Derek, any response yet?

    Derek, i understand that you order a tailor frame, them the modification is only top tube lenght in fact seat tube S and top tube M, you do not make change on chain stays.

    I have four friends with helius FR and for all there is no clearance between seat tube and tire in maximum compression, it's normal with this frame put a transparent tape on seat tube and ride like this there is no problem with your frame.

    so Nicolaï recommande to use spring shock on FR then with spring Shock you have the same situation but it's more difficult to make the test because when you remove spring the bumper limite the maximum compression for the test.

    I thing that the answer of Nicolaï is that it's normal with an helius FR.

    If you ride it for the first time this weekend do you send us first report of your ride?
    if i can recomand a setting for you, set the rebound of the RP23 as fast as you can because the ajustement of pivot points slow down the fonction of linkage, then begin like this and slow down rebound if it's necessery.

    then if you want to slow down the compression activate the pro pedal in position 1 you can make downhill like this without damage, as i said upper the frame is design for spring shock and when you use air spring it's to much linear and maximum compression is obtain easily.
    I ride it with a DHX air and I must close alf the propedal to obtain a good reaction, then with the RP23 the reaction is better than DHX air, then the Monarch work good.

    Only Just noticed this thread so sorry for the slow response

    I have a medium front and small rear frame - no changes to geo though - never any issues with tyre clearance... mine is polished so the tubes are probably a few mill in diameter smaller but should not be that much of an difference. I also have helicopter tape on the seat tube by the tyre which adds that thickness back on.

    Tyres i have run include

    2.5 Maxxis Minion
    2.4 Schwalbe Fat Albert
    2.4 continental Mountain kings

    Few questions

    Shouldn't you run the air shock in the top hole mate?
    If so do you have the same issue there?
    Is there an issue with the stroke length on your shock?
    What were the list of modifications that you asked for on the frame geo?

    Sorry my trespassing this topic......

    Hey Cyril:
    I`m newbie FR owner, and i use Continental MK 2.4 UST tire and mavic 823 USt rim. Don`t know nothing about these clearance problems....
    Another tire option is Shwalbe fat albert 2.25 UST. Shock i use is fox van r --> 200mm X 57mm stroke (or fox float 200 X 57).
    So do i have to worry about those above? The frame is size XL and 09

    Derek: Hope you get response, keep posting results with us. Ride on mate
    Sorry my poor language, big fan for the google translate.....

    @ karve, if the shock is 200 by 50mm then it should be run in the top hole, if it is 200mm by 57mm it should be run in the bottom. if it is a 50mm stroke shock and you are running it in the bottomyou would be getting less travel then 167 so i hope that its a 57mm shock.

    a little precission about travel ration of the FR you can run 200x57 on both holes see the table
    Helius_FR_travelratio_09.pdf

    if you use 200x57 you have less 137 and 155mm instead of 155 and 172mm

    I think it's the same case, you can verify it but it's not a problem the bike run perfectly like this.

    No you can't. That document was an amateurish f-up by Nicolai.
