    AC & Pedal Strike - Afflicted ?

    sorry, but is the AC afflicted with pedal strike like the AM ?

    The AC has a reported lower BB height..

    TIA

    Surely this is completely dependant on crank size?

    Not in my experience. The BB is noticeably lower than the CC on which I'd done most of my riding immediately before which resulted in a bit of pedal strike on the first few rides - I took a chunk out of a new pedal first time out at Afan. However, either I was running the shock a bit soft or I adapted my riding style and it's not been a problem since.

    You're the engineer - work it out. Remember that the stated BB height is unweighted. My rough calculation is below assuming 150mm travel front and rear on the AC and 170mm on the AM with 30% sag and that the travel is vertical at both ends (not quite accurate)- the effective 'sagged' BB height is about the same on both bikes.

    AC 11mm Sag = 45mm Effective BB height = -34mm
    AM 17.5mm Sag = 51mm Effective BB height = -33mm

    It's the effective ride height that's actually important rather than the figure on the chart - if your run your bike with short forks (either shorter A-C or lots of sag) or super sagged rear (which might depend on the model of shock and how you have it set up) your effective BB height will be lower.

    I'm really bored with your endless carping on this. You're the *only* rider who considers this to be an issue on the AM - everyone else has either not found it a problem or adapted their riding style around the advantages a low BB brings. If you don't like low BB's don't buy a bike with one. I don't believe your frame is different to anyone else's and you should be able to see if it's really significantly different just by looking at it - is the BB above or below the pedal axles?

    will check the static BB location later and report back.

    for ref, there's a few of us on this forum that suffer pedal strike, albeit, acknowledged that it can mostly be ridden around

    no need to get shirty or defensive

    it's the nicolai forum.

    i chose the forum to detail issues with my nicolai.

    sorry if that's controversial, but a forum offers an audience to discuss issues.

    as i said, no need to get defensive or attribute personal retribution

    Set your AM in a lower travel setting. You keep saying you don't need 160mm so why run your shock in the 160 setting? It'll help no end with your pedal strike! An AC is not the bike for you IMO

    We have sold a bunch of AC and are riding area is rocky and technical and we have
    not had any problems with pedal strike. Bike setup is crucial on any bike to prevent pedal
    strike!

    I will admit i have hit my cranks and pedals a few times in the Many hundreds of miles i have put on my AC.All were my fault,The BB is in my opinion perfect on the AC for the type of bike it is.
    I like a reasonably low BB as it improves handling and cornering.

    How's that? There's 4 holes! Didn't you 'calculate' the top hole as 171mm? That makes the 2nd hole 160ish. no?

    Second hole down is I think 157mm but we're really splitting hairs now.

    I think TLR has admitted that his pedal strike problem is now much better right Simon? I think if you drop to the third hole down you'll find it goes altogether but you'll need a lighter spring.

    Really bored of this. Tlr I often enjoy your banter and stirring but banging on about a non issue strikes me as being a little well..... Special.
    I can understand Nic uk getting shirty. Please remember many more people read this forum than post, and your unnecessary criticism only serves to make Simons job harder when dealing with the misinformed general public.

    Have you seen the bos thread? Nearly 18000 views and it's littered with "French tat" nonsense! How many potential buyers that don't know the score are put off buying bos by the sheer amount of negativity from someone who hasn't even ridden them? It's not just on here either. The suspension thread and stw also get spammed with it! It helps no one.

    Maybe he's hoping for a bit of self fulfilling prophecy!

    so.

    i suffered incredible amounts of pedal strike and asked for assistance / feedback / potential fixes for over 2 years.

    i received one from STENDEC on a custom tuned CCDB.

    my AM and my local terrain obviously didn't mix too well.

    sorry for being a dick.

    i now know where i stand. in the shadow of your collective superiority.

    Don't apologise for what you are Get out on your AM, mash those trails and revel in the Nics awesome handling, stiffness and tracking.
    Unbelievable weather in the midlands today! So looking forwards to the summer riding

    And yet you're still on the same pedals as 2 years ago(Easton flat boys on original pins and a pair of xt spd's? Plenty lads that don't suffer from pedal strike go through more pedals than that in 2 years! I've no doubt you get pedal strike but fail to see why it's such a big deal. Having ridden loads of your local trails in the last few weeks on both the afr and ac29er I agree It can be very rocky so some pedal strikes a given.

    How's the vf2 for pedal strikes?

    Your not a dick for having your pedal strike/riding issue, your not a dick for asking for assistance/feedback, your a dick for the childlike spoilt brat way in which you trample over other members threads in a tangential, xenophobic obsessively pedantic manner

    TLR, try some thinner pedals? Point one, Spank and Nukeproof might be worth considering?

    I haven't ridden the AM but so far, no pedal strike issues with my AC, neither with a "low" Pike of 520mm A2C, neither with my Revelation 150mm. I'll put a Nixon 160mm and see how it goes.

    I don't have a pale idea of the BB height on an AM, but my AC with the Revelation gives me (off the top of my head) 13.75"... maybe 13.5" but I seem to recall the BB height was the same as my Switchblade and I'm dead sure that was 13.75". That is a with a Larsen 2.35" rear, the Revelation (specc'ed fork by Nicolai @ 527mmA2C) and an Ardent 2.25" up front.

    I'm running Shimano 647's and I can't stand anything smaller than 175mm cranks.

    The only times I stroke a pedal to ground were one climb when I was riding the Pike at 110mm travel and it was really rocky and once that I was running more sag than needed on the Monarch.

    Actually, I think the Monarch finally bed in and I'm blowing through the travel a bit too easy and I'll have to correct that, especially because the Monarch rides deeper in dynamic sag than a Fox even when you run the FG in.

    A coil over had sweeter mid-stroke than the Monarch with the large can, so listen to the Fathership boys when they say a standard can is better.

    OTOH, a trailbike like this, with a BB that is 11mm above the wheels axles, you don't need a degree in vehicle dynamics to figure out that it will hardly pedal-strike unless you really jack up the shock set-up.

    Bikes like the Giant Reign and the Spesh Enduro have lower BB's, have same travel and it's actually regarded as a good quality. Go figure... to each his own, I guess.

    Besides, why would you want an AC, TLR???
    It's heavy, it doesn't have any carbon and costs like three times more than almost anything out there, and being a Nicolai, it must pedal strike.

    You know you want that Mojo SL... you'll love it.

    Gratuitous pic of a bike you don't really want...

    still think an AC on RLT Ti's and a decent shock could make good replacement AM sense.

    the VF2 however is SUBLIME.

    I really think you could do this with the -3mm shock shuttle from Nic. The -7mm on our vintage bike does drop the BB to 13" from about 13.7" so I am thinking that the -3mm one will give something around 13.4" which is more or less what the AC is. The point of the shuttle is to slacken the HA off so that it still works with 150mm Revelations.

    I think it could work. Cost is £80 as opposed to £1800 for a new frame (although the new AC can now use the old AMs dampers)

    Adj. 1. xenophobic - suffering from xenophobia; having abnormal fear or hatred of the strange or foreign
    Your rants about BoS forks was based on what exactly?

    lots of rock, off-piste and technical.

    In my opinion (TVI will no doubt disagree) its the way you hang your feet off the pedals that gives exesive pedal strike? Dont get me wrong even without that you will without correction strike the pedals from time to time.

    When we were riding and i had my Green FR my bottom bracket was lower than yours and i managed to pedal around it; its just if you want the benefits of a low BB you need to accept the traits it gives. Great handling with a couple o' pedal strikes is better than shoddy handling which a higher BB gives imho. If i were you i'd go for a completley new brand, new direction and new forum (Only joking)

    Oh my... are you actually giving me riding advice LOL !!!

    Last time you rode, RS made Mag 21's....and Turners were HL...

    I have a Cove, an On One and a Chumba to ride as well as the Nic, and they all have individual characters. None as flawed as the pedal strike on the AM however.

    See you on the trails sometime ?

    The cove and on-one are hard tails and the chumba is a shortish travel full suss. The AM is a long travel full sus. Doesn't make it flawed. It's just a different style of bike. Reduce the travel if you want to keep the bb higher(sorry, am I repeating myself? )

    haven't ridden an all mountain bike yet that doesn't have some pedal strike...goes with the territory...you either learn to adapt, accept or go shorter travel...i, for one, don't mind it on the occasions i get it wrong with a line choice, for all the other benefits...

    maybe a forum entitled 'i hate my bike, but i decide to gripe rather than move on' would be best, rather than taking up column inches (consciously or subconsciously) putting others off buying a particular brand? i'm with Nicolai UK on this one...

    let me repeat, all mountain bikes suffer from pedal strike...

    but, you know what? the perfect bike doesn't exist...if your cup is half full, you'll be pleased as the flaw of an all mountain bike gives you the opprtunity to work the trail still, and think about pedal position, rather than just blat through stuff with no thought....

    well there's a stroke of luck. I know of one for sale. problem solved. Even better for you as its been converted to a 5 pack so its lighter and does away with that extra 'too much travel for trail' inch

    Dipper,sort him out on this,do a PX on the AM,then he can dissapear off the Nicolai forum

    I had a 5 spot and have an AC,no pedal strike issues with either of them.I found the spot a little flexy on the rear compared to the AC

    @norco - i'd agree the nicolai has exemplary stiffness, albeit with the weight penalty.

    fatwheeled - my AM is flawed and remains unacknowledged.

    My AC is no heavier than my spot,just stiffer.
    The spot was a very good bike.

    Your AM is flawed or all AM's are flawed? Apologies if you've covered this before, your not exactly coherent

    no one can acknowledge what they havent ridden. give it to me for a week around aberdeen and i'll see if it differs to other Nics ive ridden

    dont think its you're old 6-pack but it is one i sold. be cheap enough to buy but will need a paint to tidy it up if you want it mint.

    Put the AC through its paces in nasty terrain. Any pedal strike was rider piloting error definitively.

    I rechecked BB height... with the Rev is 13.25".
