I’ve become a bit obsessed with products from lesser known companies over the last few months. Honestly, it’s a little bit boring that nearly every bike comes attached with forks, shocks or drivetrains from one of two brands. How did we get here? How does this happen? Sure, if you can get a well working piece of equipment at a good price, sometimes it’s easiest to take the less risky path. But us product testers? Shouldn’t we throw caution to the wind and see what else is out there? Shouldn’t we be driving our pathway to knowledge forward? Well, just like Marco Polo, here I am, about to head out on a grand, risky adventure in the pursuit of knowledge.

The Selva cuts a forkish profile.

On Formula

I mean “risky” is a strong word. Formula has been around for ages. Motorcycle stuff since the 70’s! Disc brakes for mountain bikes since the early 90’s! Suspension forks since 2012! They’re not exactly new to the game as they’ve been cranking out made in Italy stuff since…well, since a while, anyhow.

The Selva itself isn’t exactly a “new” product. The first mention I can find goes all the way back to 2016! AJ took a really detailed look at one a few years back (review and teardown) and came away impressed. Did the heavy lifting for me, too!

The killer feature, of course, is the CTS valve. Formula has figured out a way to essentially re-valve your fork without re-valving your fork. If you’re searching for a particular feel, pop in a new CTS valve and Bob’s your uncle. In total, there are eight different valves (well…nine, but more on that in a minute), each with slightly different properties – from ultra light silver to super firm electric blue.

Other things going on in the Selva

3 spring types – Coil, Single air (ridden here) and dual air. All three springs are available separately for retrofit. Single air is billed as the middle ground. Performance with light weight and ease of use.

Neopos volume spacers – A step beyond the typical hunks of plastic we’re used to jamming in our forks. Neopos compress as the air pressure differential ramps up, before a controlled expansion. The effect is to have a similar impact to the mid stroke as a plastic spacer, but less end stroke ramp.

A further alphabet city of stuff – RCC, IFT, ILS and HEX. You can dig into those things here.

Options and other things:

  • Spring types – Coil, Single Air, Dual Air
  • 650b or 29er
  • Standard (120-160mm of travel) or Extended (160-170 for 29er, 170-180 for 650b)
  • 37mm offset on 650b or 43mm offset on 29er
  • Fixed coil negative spring (coil and single air)
  • 160mm post mount
  • Tapered 1-1/8”-1.5” steerer
  • 15mm Boost or 20mm Boost
  • 35mm stanchions

Again, most of this is known and has been largely covered by AJ. What brings us here today is the fact that Formula is smart! Formula has Josh Bryceland! Formula is using Josh Bryceland to bring us a new concept in forks! Behold, the signature Josh Bryceland Selva!

The Josh Bryceland Selva

On the surface, this looks like a Selva with some special graphics applied. But under those graphics, two things are lurking. The first is a larger, more linear, air spring. The next is the mother of all CTS valves. Watch this video to find out how we got to that.

What you end up with is a gently massaged Selva, put together to satisfy Josh Bryceland, and then sold to you in limited quantities (100, to be exact). Will some of these things make it to the regular Selva? Are there many people capable of pushing their forks to a level that requires a professional level fork tune? Do I like asking questions of myself? Who knows?

If you are interested, all of this is available for the low, low price 1514 EUR, 1279 GBP, or 1750 CAD.

First Ride

As you can see in the photos, I have some suspension related gizmos that I’ve been playing with. Those are going to factor into the longer review. I have a super tunable fork here and I’m excited to see what that looks like with an advanced data acquisition system. I’ve had the fork for a week or so but just got it mounted up. I was in the process of dialling in my current system and didn’t want to interrupt that process. So, this truly is a “first ride” impression.

And so far it’s a pretty great first impression. The fork is doing everything as advertised on the box. My settings:

- 78 psi (2 below recommended)

- Rebound – 9 clicks from closed

- Compression – 1 click from fully open

- CTS valve – Super Duper Bryceland valve

This is giving me a pretty low 16% static sag that turns into about 22% dynamic sag on the trail. In talking to the folks at Formula, I was a bit intimidated by the Bryceland CTS. There’s not really a world where I see myself needing a whole lot of compression damping ramp up. A theory though. Note the axis on that damping curve. It’s force vs. speed. I mean…maybe us schlubs just never get shaft speeds that hit the steep part of the curve? Maybe this is similar to an F1 car, where if you don’t drive fast enough you can’t develop any downforce and you just slide right out the corner?

Either way, the fork is working pretty darn well. It’s super supple off the top, and the 22% dynamic sag is showing a fair amount of support through the mid stroke, with the fork riding quite high in the travel. The high damping CTS is showing itself through slightly lower compression shaft speeds. I actually made pretty good use of travel, hitting 96% at one point, so I’m not exactly sure where that’s going to take me. Through multiple, chattery hits, things are buttery smooth, and so far I have just enough ramp up to prevent a full bottom.

Next Steps

Next steps are to hit Formula up for the full gamut of CTS valves (the fork comes stock with 3 – the installed Bryceland valve, plus Gold and Orange), a few extra Neopos spacers and maybe a few other trinkets. I’m going to show you the deep, deep data that I find on this fork and try it at the different ends of the spectrum. I want to see just how usable such a tunable fork is and where it takes me with my suspension tuning. Stay tuned.

Looking forward to your findings Dave!

But yeah, 160mm post mount? Seriously?

it's crazy for sure, having to put a 40mm adapter on does feel like I'm at some kind of leverage limit and I don't know if it'll go to a 220mm / 60mm adapter as I don't think those even exist

I’ve never seen a 60mm adapter myself, and I will admit that not being able to run a 220mm rotor would be a deal breaker for me. And I’m not interested in doubling up adapters.

Hey Ryan,

Formula make an adapter for this. It doesn't use long bolts, it moves the caliper vertically up to move it out far enough, so it's actually a nice stiff adapter that uses 4 bolts (superior to the 2 bolt ones in my opinion). 

We're out of stock of them until next week but they usually live here: https://albadistribution.ca/products/front-rear-pm6-adaptor-kit?variant=22515853230198

The Formula website specs 220 mm max rotor size, that would seem to imply an adapter exists....

The bolt length really worries me, but perhaps I can just use a much thicker 200mm rotor instead

I imagine it would be one of those offset adapters with four bolts: two to fix the adapter to the fork and two to fix the caliper to the adapter.

Having done a bodge to fit a 200 rotor on a Fox 34, but without access to the single adapter I ran it doubled up for a year at least. 

Never caused me any issues. Even if it looked janky.

Why? That the bolts are long has no real bearing on their sheer strength, which is what is at work here. And probably with the torque applied to the bolts it probably doesn't really stress the bolts at all. And the only sheer exists at the mount to adapter interface and the adapter to caliper interface. Otherwise the bolt is in (very low) tension.

That’s not how bolts like that work. Bolts carry their load in tension. The load in the shear plane is carried by friction.

But your point that their length Is irrelevant is correct.

Well, I saw the video on YT week before and was kind of wondering if this would make it into media hands as they said the run was going to be so small, guess it did. 

Agree that it's sad that most bikes come with one of 2 brands forks/shocks installed and only on lower end models will you maybe see something different. 

I'll be curious to read your follow up Dave, especially with the data acquisition stuff. Interesting that you had no trouble using almost full travel and yet Mike K from PB said he only managed to use just over 80% travel on the hardest hits and switched to the gold CTS. This to me tell me that maybe this CTS tune is more for bigger/heavier riders as his fork pressure for his weight was only 65PSI, way lower than your 78PSI, so l'm guessing you've got about 30>lbs on him.

I made the same assumption and rejoiced that a heavier rider was testing this.  The PB guys are great (so are the girls a bit less so without Alicia but still all rad people) but they are all light weights literally.  If they break something I will not go anywhere near it because I weigh significantly more than them.  

Too often bike reviews all come from super light riders and when a heavier rider tries the same product the results are wildly different.  Especially with suspension components getting the setup right is really important and finding options that have the ability to change to suit very different weights can be difficult.  I was very worried when I bought my bike from a very thin person.  Amazingly I added air to get to the recommended pressures and left everything else the same and it works pretty well.  In the past I tired this with some other forks and they just never had the support unless they were way over pressured.

I always have to take a grain of salt approach to those reviews from far lighter testers than myself. Like you said, suspension reviews are especially all over the map - what works great for me doesn't work so well for someone who weighs 150lbs. Case in point: Lighter riders often struggle with the Zeb Charger 3.0's overdamped nature, and this is why it works so well for my 200lbs-geared-up self.

Well, we've got you covered!

I don't know what Dave weighs but maybe he'll tell us - anyway Tim, Ryan and I all weigh btwn 190-200 I think. Dave's the tallest and weighs something similar to us. Cam is tall but more like 165. Deniz and Cooper are similar I think at 160 or so.

I keep telling everybody I'm 200 pounds geared up.  I actually thought I had included my weight when I went through my settings!

It gets hard figuring out who I'm replying to on these comments but I've ran the 60mm adaptor on my 170mm 29er Selva C fork and it's 100% fine. No different to a 40mm one really, the caliper just sits higher up the fork rather than further out, like Ben says. The fork also feels stiff enough (for me), and has awesome traction on flat choppy corners.

" Honestly, it’s a little bit boring that nearly every bike comes attached with forks, shocks or drivetrains from one of two brands. How did we get here? How does this happen? "

The simple answer is in a competitive environment those 1 or 2 brands show up, they have the research, manufacturing, distribution  to turn out quantities  of reliable product that bike mfgrs can book and depend on to show  up for their  bikes

but I'm sure you knew that

I'm betting that the vertical line on the spring curve is the point where the neopos have compressed to maximum, and then cannot compress more and you get that weird jolt in the spring force. 

To my mind this is exactly what a spacer like that would create. A modification to the curve but potentially a significant change near the end with a dramatic spring force change. 

It'll be interesting to see what Formula say.

I've always been intrigued by Formula's approach to damping. Sadly, a tough option to pursue down here in the states.

what is static vs dynamic sag?

Reply

davetolnai
+2 BarryW Lynx .

Static = the measurement you guess at when you are setting your sag before a ride.

Dynamic = the number my fancy data acquisition system spits out after a ride.

Dynamic sag is basically the average position of your suspension while riding.  It will vary a bit depending on the steepness of the trail, amount of rebound damping, etc.  This is the one that probably matters as it's telling you where your suspension is sitting while riding.  It's just impossible to measure without some form of data acq. system.
