    I think I've got full travel back on my Devilles (not actually riden yet). I followed Mad Elk's advice and pulled up on the crown to extend to full length and then let all the air out and pumped up again, cycling every 3 bars up to 9 bar and then adjusted to ride pressure. Not in a hurry to try since I'm really liking the Idylles at the moment. Probably going to use the Devilles with a lighter 650b build I have in mind. Next, I'm going to get my Stoy retuned for my new frame to replace the DB air. I'm sceptical if the new BOS air forks are going to be as good as the old coil's, since switching from Devilles to Idylle I can really feel the difference.

    @Tdmax: i wonder if the detergents in your bike wash have caused issues - you dnt use muc off or such thing do you? My seals are mint and I ride in all sorts of crap (Uk weather and all that).

    I have a couple of friends who have all jumped onto DH air Idylles from the coil versions and swear by them over the coil versions. Im likely going to try a set and a void next year, feel free to come have a go when they are here. Would be good to catchup again.

    If that's the case then I'm getting some as well. They won't be as reliable though? And they don't have 1 1/8 steerer which is an advantage when fitting to a 1.5 head tube because you can keep the front lower by using a ZS bottom cup. When is the SC air available?

    Hi Viking, i usually clean my bikes only by water, i use a drop of soap only on the frame.
    Usually i need only to remove dry dust, Rarely i ride on mud because here we have a lot of rocks and gravel.
    I use a motorbike soap but i always used it on all my bikes and motorbikes and this is the first time i have a problem.

    About lubricating stanchion i think it would be useful on wet condition, in my case i think that oil can attract dust. Am i right?

    How do you lube the stanchion? I try to keep it clean and avoid to wash with water/detergent but i've never lube it. After 8 months of abuse mine is getting a bit dry and lost the initial extra plush feeling, anyway is awesome. In the next month there's an enduro race, after that i plan to make a service.

    Bos say not to use anything at all but I quite like a little spray of this stuff....and then wipe down so its not dripping and doesnt attract grime and crud. My seals are like new on both sets of forks I have (devilles and Idylles)

    Fork Juice

    Do you wash your forks only with water right?
    I usually do the same.

    Sometime i use teflonglide oil (protone suspensions special product).

    Fork Juice spray or Stendec fork grease.

    I use Brunox Deo fork lube after rides

    also I recommend you to check the oil level in air leg -> I had the same issues (not feeling very plush) and after oil check (there was none!) the fork became amazing again

    How did you do it?
    I don't know how to open the fork
    on one leg there is a socked head scew, ok, but on the other?
    You need to remove knobs?

    Pilot, Viking,
    Like you guys I love the S**Toy on my 26" '011 AM.
    Having just got a VIP'r from Dipper, though, I have to say that's a hell of a lot easier to pedal. It's very smooth too, very grippy, good on roots. Of course I'm sureI can't expect it to hold up as well on big "Alpine" rocks as the Stoy, but right now in the woods it's giving me a far easier time pedalling up.
    I have quite a few BOS bits now so I really hope UK servicing works out with the Irish bunch.

    Man the mud is sticky here in Brighton, full of leaves too, really blocks the transmission big time. The woods are certainly looking beautiful though.
    Viking, I must come up to Swinley again when (if) it dries out a bit, riding your tracks was a great day out. Thanks again of the session.
    Neil

    I've got a Deville 170 and a Vip'r on my Helius AM, and they work very well!
    But i may use them a bit too hard





    For the moment, nothing goes wrong... It works exactly as i want!

    I'd be carefull with Brunox. I dont think BOS recommend this solution to their forks as it dissolves the grease from underneath the seals.

    Regarding the Mad Elk boys they are well known here in Dublin. Sound lads and very passionate riders. Good luck to them.

    Got my Deville of them last week and had a chat with them. They did the servicing training in France and I saw they had the BOS tools too.

    I thought my Lyriks were awesome but no - this is awesome. Ordered a Vipr too to as at the moment my bike rides like a racing horse shot in the arse - amazingly performing front bouncers + rear monarch RT3 trying to follow

    Hia,

    Good to have your opinion of the Mad Elk guys, such a releif that we now have an English speaking Service centre.

    Enjoy your Deville, it's pretty tough, designed for Enduro, developed by monsieur Vouilloz I think, have you seen the vid. of him on Devilles. He rides pretty hard (smooth tho).
    Vouilloz testing the BOS Deville
    Mind you, if you like the Deville you might love the Idylle SC, fair bit more hardcore and even better than Deville in some ways, stiffer for sure, definitely has the same "family" feel.
    Mind you, so does VIP'r and S**Toy.

    Is Brunox similar to Fork Juice? BOS definitely dont want solvents near there but
    I think a silicon lube spray is ok, BOS manual says:
    "3.2 Cleaning your forks
    It is compulsory to clean your forks every time you use them, without waiting !
    Nothing’s worse for your fork’s seals than dry mud.
    It is very simple to clean your forks : wipe off the stanchion with a clean rag and then slightly lube the stanchion (with silicon based product). Use of degreaser is totally forbidden.
    On the same note do not power wash the forks! It will only push the mud inside the forks and get it stuck between the stanchion and the seals."

    Have fun
    Neil

    Deville are lighter than the Idylle and I needed 170mm max. For the rear I wanted to get the Void but no luck since they don't come in 200x57 sizes. I'd say Vipr will be a good match for the devilles and more balanced on uphills.

    Hi

    Does anyone have any experience of the vip'r clicking as it goes through its travel in the soft setting? It's fairly loud and pretty off putting when riding. The shock is new and had been back to France already but it's come back and still sounding a touch ropey. It's on a tracer 2.

    It's "normal":

    It depends of the setting. You can't change it.

    I never heard that
    Have you really carefully gone through the equalisation?
    Are you SURE it's the shock?
    Can you put the old one back on and not have the noise?
    If so, you then need to look at the shock mounting points [bushings] carefully.
    Could it be the bar, the seat, the seatpost??

    - I sometimes work in a bike shop and strange noises from bikes are the basis of much discussion. They can come from the weirdest places.
    Example - carbon bike, creaking rear dropouts - no - front mech band was the cause!
    Creaking suspension bushings? no - seat rails!
    Creaking crankset, no bar/stem interface.
    and on and on.

    It sometimes feels like the old VW ad :

    Sounds like low oil level. I had the same problems. Seems they do not fill too well in the factory. It IS a pain to fill properly, and it takes time.

    You definitely need to balance the chambers, I posted instructions above. It doesn't sound right though. Please let us know how it turns out

    For Info: It's my third Deville...

    I alredy balanced the chambers twice and it is still doing the same noise...

    So, i called directly Bos this morning and they sent me a new one for saturday.
    I hope that It will arrive on time...
    And for info, this sound could also come from a spring fixed in a wrong place

    So, my new deville arrived today, just 24h exactly after the sending
    And It works perfectly.
    I have to thank my shop and Bos for this reactivity.

    It is indeed -
    I see this now:
    On movember 26th Surf Sales signed a new distribution contract with what we regard as the finest mountain bike suspension engineered today, to complement it we'll be opening a service centre with full back up and we'll be offering the suspension as an upgrade to Transition bikes, notably The Bandit & Covert Carbon deville.
    Our service centre staff training commences on December 17th and stock is expected by the middle of the month, certainly in enough time to commence 2013 with products and service capability.

    To be fair to R53 I think they themselves were a reliable company. Roger certainly knows his stuff with suspension.
    I hope that the size of Surf Sales will help them hold stock of parts aswell as components.

    R53 are very good,I think its more to do with BOS not supporting them with parts.

    Service and info of Bos Deville and Vip'r

    Hello Guys,


    Where is you bike shop? I would like to know if is possible to modify the travel of my Deville 160mm TRC to 170mm? I would like to do this mod and also service my fork and shock. Since four months ago I have tried to contact BOS directly without any result, and my fork and shock need service.

    Thank you for your attention and time, waiting for your reply.


    Regards,

    What we know there is new All-mountain platform being released in spring time. We haven't heard about bos 650b forks yet. But actual bos forks have enough clearance for 650b wheel, claimed.

    Hi there,
    We are located in Dublin, Ireland.

    According to conversion question I double check with guys in France. What I can see you need to re-built internals witch gonna cost more then just "a spacer" . But I will come back to you with definite answer asap.

    About the servicing your suspension just pack it with service form filled out. The form can be found at
    Contact us - Mad Elk Cycles and follow instructions there. it takes up to 7 working days to get back your fork/shock when in Europe.

    Hi godzilla, try pulling up on the crown while holding down on the axle so that they extend to full travel and then equalise in small steps up to 9 bar. Then finally reduce to working pressure. Let us know how you get on.

    I tried this but the forks are very powerful, when the button on the shock pump is pressed they suck down and i cant hold them apart.

    ok, try equalising in reverse by reducing the pressure bit by bit. Seems like pressure build up in the negative chamber? You might want to ring Mad Elks and discuss the problem with them.

    Add the high air pressure back to fork. While proceeding the equalization with continuous releasing of the air little by little it should bring the pressure low in negative chamber. As it's explained above pressure built in negative chamber needs to be equalized back with positive one. It's worth to have a friend handy who can help you pull fork apart. See how that works and let us know

    Thank you for your attention and time, waiting for your reply.


    Regards,
    here is update regarding to conversion from 160TRC to 170:
    1. new air chamber unit(piston,shaft,support)
    2. new cap to replace TRC one
    3. change height of lower slide bushes( replacing all bushes + seals to complete a job)
    4. modify cartridge or buy new one.
    The whole job would cost you quite a lot. I recommend you to buy a new one.
    Stefan

    Love my BOS Suuspension and have 2 forks + 2 shocks unfortunately Surf Sales apparently still don't have the service kit and are not hearing back from BOS.
    BOS themselves didn't reply to my email [in French] requesting service 9 days ago.
    So, I'm sending my Deville and S**Toy to the very friendly and helpful James at J-Tech

    Vikingboy said "Just Believe" [quoting Jedi] he's right. I am doing.

    Hi mudfish, that's not good news that Surf are not up and running, probably not their fault. Let us know how you get on with J Tech. I need a retune on my Stoy and was thinking of asking Mad Elks to do the work.
