BOS Suspension Announces New Enduro & DH Forks With 39mm Stanchions

BOS Idylle 39

After a multi-year hiatus, BOS Suspension is re-entering the mountain bike world with the launch of two new air-sprung forks, the Idylle 39SC and the dual-crown Idylle 39 FCV.

The Idylle 39SC is designed for enduro or downhill usage, and it's available with 170, 180, or 190mm of travel. As the name suggests, it has 39mm stanchions, which BOS says was done for more rigidity and precision. It also just so happens to be 1mm wider than the stanchion diameter of the RockShox Zeb, Fox 38, and Ohlins RXF38.

The 39SC uses a sealed cartridge design, with a a three position low-speed compression dial that allows for additional adjustments in the open position. The fork is only available for 29" wheels, and has 52mm of offset. The price is 1,640 Euro.

The Idylle 39FCV has 208mm of travel, and uses an open bath hydraulic cartridge with low- and high-speed compression adjustments, plus rebound. Like the single crown version, the 39FCV is also available with either a 15mm or 20mm thru-axle, and is designed for 29" wheels. It's priced at 2,260 Euro.

It's worth noting that BOS has a mixed track record in the mountain bike world due to customer service issues, and the fact that they've left to focus their efforts on motorsports more than once. We'll see if the French suspension manufacturer is in it for the long haul this time around.

 Well, it's one stiffer, isn't it? It's not 38. You see, most blokes, you know, will be riding at 38. You're on 38 here, all the way up, all the way up, all the way up, you're on 38 on your bike. Where can you go from there? Where?

39. Exactly. One stiffer

 @Davec85: A tube with a larger diameter and thin wall can resist bending better than a tube of a smaller diameter with a thicker wall. While both tubes may have the same amount of material and weight, like a beam, the farther away you get from the neutral axis, the more load is carried.

That said, a thinner wall may dent more easily, so it is a balance.

 @JanB: On BOS's website they have an inveted DH fork that I believe has 42mm stanchions. I don't understand French very well (couldn't find a way to put it in English but didn't try to), so I could be wrong, but it seemed to have 42mm stanchions. And inverted dual crown. So the answer to the ultimate question is not just 42, but also inverted and dual crown forks in that case.

 @yeti85: I am not french, and I have no complaints with french customer service in general.

Sad to see a statement like that, as in the bicycle sector, I found that a lot of french smaller companies are pushing and busting their asses to release great products with great services at a decent price.
  • 6 2
 @gui21st: sad to see one big company relying on the great history of french racing innovation creating a bad name for everyone else.
On my personal experience, talking honestly now, without provocative European clichés, I'd love to see one of those small companies succeed, regardless if they're French or not. BOS is just an excellent example of the big company relying on their name a screwing it up. The smaller companies also have the best customer service.

Also on a separate personal note, I have never experienced good customer service from a French company, but this relates to industrial products. Bicycle related I can only speak about the non-existing service offered back then by BOS.

 Well I had worked with BOS for years and yes there had been not so bright times for reasons that came out to the public as terrible customer support. And it is one thing to speak out as a frustrated customer but to bash a company because they had some troubled years is just stupid and silly.
Sometimes the work that had been put into an organisation is not visible at first glace and in the case of BOS the damage was just to big to get it sorted out by them self.

BOS has always produced finest suspension stuff and their technology has been the breakthrough for our existing tech we still use.
Sure the success that the company had in the motor driven world was sort of unexpected for BOS and the demand of service to support multiple WRC teams, MotoX Teams just took its toll on the bike side of the business. Our world Cup mechanic needed to work double duties for UCI Events and WRC events - he has spoken alot how hard it is to find suitable service centers and staff to increase service quality.
For sure not all decisions made in the past turned out to be good ones, but Olivier is still very passionate and hungry for winning WC DH races. And I would bet my ass that he has put not only the money in the R&D but also in staffing and building better Service.

It is hard for a brand if the public opinion is not trustworthy, lets be more open to this nice and welcome challenger.
Other brands also had troubled years and come out stronger.
  • 2 0
 @yeti85: Well they do have very sucessful companies with great products and great services, specifically in the suspension sector with companies like Fast, X1 racing, Novyparts, Crconception...

I don't think Bos' terrible customer service was intentional however, though it did tarnish their good name. More an issue of not allocating enough manpower/money to their bike branch as it was not their core business.

As I see it, it's more up to the company's policy rather than the country they're based in. And as far I'm concerned, my only experience with "Swiss" customer service was a mail to BMC that never got answered...

There are plenty of good service centers, that is imo just an excuse.
If you don't have the time to have a proper customer support for mtb products because you're too busy with MX and WRC then stop selling those products. Nothing is more frustrating than buying a expensive fork/shock and once you need a service or a part you're f..ked

 I tried to get an axle 15mm->20mm for my BOS Deville. It was out of stock pretty much everywhere, the distributor in France Probikeshop was telling me "next month". After 3 months of hunting, I sent some email to BOS in Toulouse. No answer. At the end of the day, I found one part in stock somewhere I could order the part via a local bike shop. I even got messages from some other people on Pinkbike Buy&Sell that were looking for the same part! Another bike shop who was selling BOS here in Belgium told me they stopped selling their forks because they were asked to buy a batch of 20 of those per year.

 @x-rider: Well, the old hydraulic cartridges from back in the day (deville, idylle) are still competetive 10 years later, same can be said about the coil rear suspension. Not the air springs, but these were crap with everyone back then.

I would love to see BOS back, but currently, with a french only website, absurd spare part prices (170 Euros for bushings????) and no German Distributor - I do not see them back in the Game, at least not in Germany.
Would love to try one out, but not under these conditions.

EDIT: To be fair, they have spares available to everyone at the website. Even for old models now. So that is actually better than back when they were still in the market Smile

 @x-rider: my experience with BOS (back in 2012) was so bad that I will never buy any of their products ever again. And I have made sure to spread this message among my riding buddies.

Their products may be "finest", but they don't last. My then brand new deville blew an internal seal mid-race.
Then, if you have a problem, it's the complete inability to cope from their side paired with the good old french nonchalance.

Anyway, I missed a few races and wrote off the Deville. Been on Rock Shox ever since, never looked back.

 @mo-T: I watched my friends BOS enduro fork separate internally. Literally the lowers and front wheel shot off the stanchions and he suffered one of the worst concussions I’ve ever seen. It was his 2nd ride on a brand new YT bike that came with the fork.

If he had been on any more of a technical section of trail.. or a jump? Dude could have died. Couldn’t pay me to touch BOS.

What made the Totem better than a Marzo 66?

Honest curiosity,
I had a 66, great fork, heavy, but bulletproof, easy to maintain/tune, coil, worked great.
Never rode a Totem, and I haven’t heard an argument for them over the 66

 @onawalk: I had the totem and preferred it over the 66 because it was lighter and yet it was stiffer.

 @Kamiizoo: fair, the old bigger is better.

@artistformlyknowasdan fair play, even my first gen 66RC was a show stopper. They just kept adding letters, and making better forks

@Balgaroth fair play, I dont think the weight was much of an issue, I was strugglef*cking to get a 45lb bike to the top of any climb. How did you not like the feel of a 66 coil, I can’t think of any coil fork that feels worse than an air fork, just for feel mind

@chakaping I’d second that statement, and third it really
They were so tuneable, different weight and volume of oil, boom, you had a different fork.

HEY @DVOSuspension what do you think about bringing back the 66, show these Zeb, and 38 clowns what a freeride fork is meant to be.
  • 1 1
 @onawalk: "bringing back the 66" thats what the Onyx is.
  • 1 1
 @hamncheez: Took a look, with actual interest in purchasing. However the Onyx, even given the added weight, sadly is another air fork, with a negative pre-load spring. Bladder controlled compression circuit, blah, blah, blah.
So not quite the simplicity, tunability, or support that i was thinking of.

It’s got the weight in common with the 66 though….
  • 1 0
 @onawalk: Have you ridden a DVO? Its indistinguishable from a coil. It feels more like my 888 of old than any fork on the market today. It even has the weaknesses of those old Marz forks- so supple to the point that it dives like crazy and uses up way too much travel.

The Onyx itself, comparing equal travel/wheel size, is 20 grams more than the Fox 38. Is that "too heavy"?
  • 1 0
 @hamncheez: I have not ridden a DVO fork, and I’m actively interested.
Currently on a Lyrik, with a MRP ramp control cartridge, and Vorsprung Luftkappe. Shout out to @Vorsprung for making some great products. I am waiting for the Lyrik coil Smashpot to come back in stock, to give that a try.

I have no allegiance to a certain brand, I’ll try them all if given the chance. I like the playfulness of the Lyrik, for everyday riding, and I feel faster on the Fox, but if I’m not racing for money, I’d rather have fun.

I’m trying to get away from the lack of mid-stroke support and excessive dive, the Luftkappe helped, but I’m hoping for better. (It’s possible I’m faster than I was, which is having an effect, especially in corners)

If the Onyx is heavier than the 38 and Zeb, its certainly heavier than my Lyrik, and I dont see the performance benefit if it does suffer from what you quoted. That still makes it heavier than a coil converted Lyrik I think, which I’m hoping is a great conversion.

I’m not interested in weight savings, for the sake of weight savings, but there needs to be an obvious benefit. Have I misunderstood what the benefit is?

 @filryan: We do. BOS Service NZ. We have no problems getting product or spare parts from BOS in France, and run with an overnight turnaround for servicing. We've also supplied parts and done some servicing for customers in Australia, Canada and Indonesia so its not really a problem to get support.
We stand behind the product 100%, and for our customers who run BOS, they find its really difficult to go back to one of the mainstream brands because the performance of the BOS forks and shocks is so good.

 @filryan: We've been running the dedicated NZ BOS service centre since late 2014. Still have customers rocking the 34mm Devilles and Kirks released that year - regular servicing keeps them running sweet (as with any suspension brand).
We had some issues with creaking crown steerers on the initial YT run, but BOS replaced every one of those CSU's under warranty (and with most of these also well outside of their warranty period) on a very short turnaround.
I get that people are hung up on poor service experiences in other places around the world, but we haven't got any of that down here in NZ - the key is having experienced service support and parts available.

 How many times has BOS "re-entered" the MTB market in the last 5 years? This is at least #2 if not #3, they have no credibility, are expensive and weird choices like 52mm offset on the 29er SC. Why would anyone buy these exactly?
  • 10 3
 Sorry but only available in 29? What the hell is the industry doing making 27.5 obsolete? It was bad enough when they got rid of 26 for no reason other than marketing rubbish.. The fact is the industry is deciding and dictating what we are going to buy and taking the actual choice away from us. In the process charging us even more money for it than ever!!

We inspected the fork, it is not a manufacturing defect, here's your invoce of 370eur(the fork has been bought directly from Toulouse in a blowout sale for ~540eur).
-did you take it apart?
-no, you must pay in advance for the service, till your payment is complete, we do not open up your fork.
-so you don't know if it's the bushings caused the stanchion wear or not.
-most likely a small piece of stone got stuck at the seals and that damadged the stanchion(i lolled at this part). No warranty for that.
-but you just assuming, and still havent opened up the fork.
-no, that would require an oil change and that would cost money.
-okay, take the fork apart, check the internals and then i might be willing to pay for your service.

Long silence, a product manager joined the party, then i've recieved an email from a technician that the bushings were indeed f'ed, and they will replace the csu under warranty. But i must pay 220eur.

The story started at the last months of 2019. Since then i'm a happy owner of a Lyrik rc2, and these lovely guys at Toulouse can suck on that deville.

 That's funny. Same thing happened to mine. Got it back, it worked amazing for a couple of months then started leaking oil all over the place again.

 Do they have a website now? Does anyone over there speak English? Did the BOS thing back in 2016...the stuff was amazing when it worked...then it broke and I was SOL...

 Exactly. The Deville on the GF’s Capra was possibly the best fork I’ve ever ridden, until it started to need reinflating every day you wanted to ride it. The same with the BOS air shock on the rear, it felt as nice as my CCDB, until it started getting temperamental and needing setting up again every time you wanted to use it.

 BOS, still need help getting my Idyle rare back in tip top form. Was the best feeling fork ever, for a month. Cant find parts, service, any manuals, directions for servicing..... cmon.... please?! Bought with warranty from an authorized shop that no longer does them? What can I do?

Been hanging on the wall for 3 years now.....

 They never left the MTB market since 2010 or whenever the og Devilles came out. Just because it's not on Pinkbike doesn't mean it doesn't exist. There was a Deville launch last year, Obsys in 2018 or something, varios generations of Void and Idylles, Syors and so on. Website been live the whole time with shop and everything. I have had og Deville 26, Idylles, Vipr2, Deville 27.5 and Dizzy. They all worked fine, easy to service and finish on internal parts second to none with great attention to detail. Aftermarket support kind of crap, but it ain't rocket science to just order the correct size skf seals and off the shelf o-rings and fluid. Never had a warranty issue though...

 A company can't expect all their consumers to be as handy as you. Proper aftersales support is almost more important than a high quality product. Rockshox is living proof.

 Why 52mm offset? Dont slack enduro bikes typically come with 42/44mm? My old 29er with a 67.5 HTA had 51.
  • 3 1
 No thank you...I had a YT with BOS suspension in 2015 and had nothing but problems with both the fork and the shock...sent the shock to be serviced (twice) and the low speed compression never worked. Calling BOS for support was a waste of time...at this point if someone gave me a BOS fork and shock I would just put them up on Craigslist for $1...

 I rode their triple crown option many years back on a loaner bike. I was like night and day different with other forks. I almost bought one but was put off by the customer service issues. Shame really as they did bring something different to the table.

 When is Mike Levy going to take the same approach to fork stanchions as he did with the Grin Donut? Just make his own at 55mm with 250mm of travel.

 Sorry Bos, I will never use your products again, whilst they felt amazing when they worked, they fell apart on me and the warranty was the worst I have ever experienced in the bike industry (even worse than Canyon).

 I bought every high end fork we could get into our bike shop. The BOS was far far superior. It was an awesome couple months when they actually had some support through a solid US distributor.

 Tried a Deville in the US, and when it came time for service I felt like a real dumb-ass. At least the steerer tube didn't fail on it like many did 4-5 years ago. Went back to Rock Shox Lyrik and never looked back.

 Still riding my 6 year old Deville, best fork I have ever had and I'll never buy BOS again. Terrible customer support and no service center in the US or Canada currently afaik.

 Their products have always been decent. It's the aftersales support that had always been lacking. I hope they took this time to sort out their business and not just try to one up Fox and RS with an odd number.

 Is this an archived post from 2015? I didn’t know Bos was still even a company. Trying to get service parts took so long it makes pandemic level waits seem short.

 BOS has a pretty big stick in the Moto, Rally and (oddly enough) diving market. They're doing fine. I do wish their MTB support was better because everybody loves it until it needs service.

 @ksyz: not too hard since it is a closed bath. Change seals and bushings to SKF, experiment with oil amount and viscosity..the standard stuff. Craig at Avalanche works on the cartridge mod.

id prefer 38 and 40 mm stanchions so you can use other cartridges as well and make your own adapters.
