34 160 CTD v BOS DeVille 160

Richie63

Bit of a toss up between Fox's new 34 160 CTD fork and the none TRC Bos Deville to fit on an Intense Carbine there is little in the price to worry me so don't talk about that.

Where the choice comes from is the weight appeal of the 34mm stantions of both these forks over the 36mm Fox 36 Float that I did consider.

The conundrum I have is the lack of user feed back on the CTD fork or the Bos for that matter

Any thoughts?

The BOS is sweet and looks the nuts. Couldnt comment on the CTD. I am sure you would be happy with the BOS.

Is the 34 much lighter than the 36?

Well not that much TBH

Float 2.04 kg
34 CTD 1.95 kg

supersonic

Even "I'm a weight weenie sonic" would put up with the extra 90g lol.

Richie63

What was appealing as well was the apparent possibly benefits of the CTD system. But again ?

supersonic

I've not tried it, i think they have released it to compete with the RS RCT3 - but the old system seems to offer more absolute adjustability, if not as intuitive.

Richie63

um I have a few days to decide while at work I'll do some more internet hunting see what I can turn up :?

According to the fox website, 36 float 160 is 2.14Kg rather than the 2.04Kg you state sonic, anyways its between 100-200 grams heavier than the 34. Its a tough one, I personally love the feel of the damper in fox's, not tried the Bos forks, but would very much like too, pretty close to call, from reading reviews if you want pure a Am/enduro fork, get the Deville, if you want a more all-round trail fork, get the 34, its quite divey apparently.

supersonic

The CTD omits the infinitely adjustable low speed compression - a backwards step if you ask me. Though you get some adjustability in 'trail' mode, in open I can see dive being an issue too.

RCT3 offers full independant LSC adjust.

can't comment on the fox, but the deville is an amazing fork. been using mine for over a year now and its never failed to impress me.

I'd get the BOS, mainly due to the fact I'm a Fox hater (the forks, as opposed to the little furry vermin).

I personally think that Fox design their forks more for whippets like you (Richie) and Lawman, and not for the more "ample" fatty like me. My 2011 150mm 32s were without a shadow of a doubt the worst forks I've ever owned and I couldn't get rid of them fast enough. The Dive was appaling on them. Never had that problem with any of the previous RS forks, or the double agents on the bionicobvious.

That's curious, CWNT, since I can't get RS forks to behave like I want them, without suffering problematic dive all the time. The Fox36s, however, can be set up precisely the way I've always wished I could set a pair of forks up.

I would avoid BOS at the moment. There is no UK importer at the moment which means no spares, warranty repairs or uk backup. I would buy a Lyrik over the Fox 36, the RC2DH is by far the best 160mm fork I have ridden, nicer than the 2012 Fox 36 and a bit nicer than the Marzocchi 66.

Very much this. Having a set of rev's and fox's, I can't get the rev's to feel as good as the 32's, they dive alot and feel abit wooden in feel, just feels like riding the air spring rather than the damper like I can set the fox's up, which is why I don't really like the dual air system, as I can't get on with it, its more hassle for a fork that doesn't perform as well. Also I find the rev's when run at 140mm with a 9mm bolt thru axle are flexy, and I'm no heavy weight. Personally I would go Fox, especially as Rockmonkey points out there is no back up atm, and Mojo's service is second to none.

supersonic

Add more LSC?! Plus if you don't have the floodgate set it can effect it too.

YeehaaMcgee

That's the problem, Sonic - the floodgate system is just bollorks, really. It just doesn't really do the job.

supersonic

Depends what you want it to do - all LSC systems are only low speed because they must have a blow off, or be shimmed (otherwise they would damp at medium and high speeds - and overdamp at that, as damping is proportional to the square of the shaft speed). Floodgate lets you set where the blow off is. I can set my fork to hardly move or dive (if I want it to) yet still be supple on larger hits. Combined with the Dual Air I can get almost any feel I want. The only problem is that very large hits are under damped, but BB solves that.

benpinnick

My RCT3s are ace, yes they suffer from some flex (particularly twanging) but they are light for 150s so thats to be expected, and the damping is better than any fox Ive ever had. The Moco damper offers great support - no dive for me at all. Likewise I much prefer my sids to the F120s I had. Lighter, better damped, stiffer, and the lockout is actually useful (as a totally locked out fork is basically F all use on a mountain bike). Only thing I REALLY miss is the awesome Shimano 15mm axle. that is soooo much better than Maxle.

I know what you're saying, but it just does not seem possible to get an RS fork to be a nice stable platform, that is always responsive to high speed movement, whilst still controlling low frequency movement.
The "low speed damper" is either on or off - if there's high speed impact, you lose low speed damping totally, and the rest of the time, the fork is unresponsive to normal trail bumps.

Richie63

Just throwing a curve ball into the mix the ctd are 15mm axlewhile Bos and Float are 20mm is there really that much stiffness lost in the smaller axle size to notice

So my other point of all this is why produce a 160mm ctd fork if when you look at the specs it comes up short at performing or have fox just made a fork for people who want a160mm fork and are never going to use it to its full potential, or does it actually perform?

At the moment the bike I'm building is a replacement for the Sworks enduro with 160 vans on that I currently abuse.

Agreed. The Fox Qr is miles better than maxle, very much wish my frame had one rather than the shitty maxle

supersonic

Maybe is just a personal feel thing - works for me! I run the LSC and FG quite high, and 10psi more in the negative chamber. This makes them supple at the start of the stroke, but seems to resist bob and dive well. The air system ramps up nicely at the end. Granted it took some fiddling, but once nailed it seems to do the job. For bigger forks and harder riding though I prefer the Black Box damper or Mission Control.

rocketmonkey makes a good point actually, right now there is no uk distributor for Bos. i know there is one suspension servicing place that have started servicing them, but i can't remember who.

saying that, the deville was designed and built to have very long service intervals. bos recommend a service every year if you ride alot, or every 2 years if you only ride once or twice a week. Whereas fox's service intervals are just ridiculous.

I had my devilles serviced after a year of pretty hard riding, and the guy at r53 (the old distributor) said they were absolutely spotless and like new inside.
