Formula The One Disc Brake Formula's 'The One' 2011 disc brakes are an attempt to produce a brake with downhill power at cross-country weight. At 782 grams for the complete front and rear set we tested, they certainly hit the mark in the weight department, but does that translate into useable power when descending? Pinkbike spent six months running Formula The One brakes on our Intense M9 in all manner of conditions across Europe and North America in an attempt to uncover what makes them tick, and to discover if they are truly up to the job of stopping heavy bikes and riders from high speeds.

The One Details Featuring forged lever bodies and calipers, Formula have pared away all extraneous material to create a brake that is both lightweight and strong, and pulling the brake out of the box reveals just how light they truly are. There are a number of rotor options, from the midget 160mm, good for 4x and trail, right up to the full blooded 203mm rotors that we used for the majority of our testing. At first you may think that the low weight means the brakes will never stand up to any real levels of abuse, but that's a fallacy. It's merely after becoming so used to a lot of other brakes it's logical to think that either light equals weak or strong equals heavy. Featuring lightweight aluminium Torx hardware throughout, our brakes also came equipped with a full complement of optional adjusters that enable tool-free reach adjustment. The IRA (Instant Reach Adjustment) replaces the lever's threaded push-rod which is normally accessed with a 2mm Allen key. The FCS (Feel Control System) is basically an in-line bite point adjuster and something that the standard brake doesn't have, but probably should.
The IRA dial on the lever adjusts the lever's reach, while the in-line barrel-adjustment where the hose exits the brake reservoir is the FCS bite-adjustment function. Both are optional.
Formula uses aluminium Torx screws to save some grams. The One levers can be flipped right to left, and there is an optional 'Mixmaster' clamp for those who want direct-mount shift levers.
Lever assembly: The One lever assemblies are reversible and feature a two-bolt clamp. The master cylinder and reservoir is radial which makes for a compact configuration. Most of its hardware is lightweight aluminium, and Formula's gram-saving design forgoes most external adjustment features. The standard The One brake has only a simple reach adjustment that requires a 2mm Allen key to set the lever distance from the grip.
Choose your lever options: For those who want a full-featured lever, Formula offers two add-ons: IRA (Instant Reach Adjustment), a machined-aluminium dial-adjust feature that allows tool-free lever-reach changes; and FCS (Feel Control System) a hydraulic barrel adjustment that sets the system's 'bite point'—the point in the lever travel where the pads contact the rotor.
The two oversized 24mm caliper pistons clamp the disc hard and a forged, one-piece forged aluminium body keeps the caliper lightweight and rigid.
The One Caliper: Formula's forged, one-piece aluminium caliper has a slightly larger-diameter piston than its cross-country brakes use. This is to boost the mechanical advantage between the master cylinder and the caliper. Sintered metallic or semi-metallic brake pads are available (metallic are standard) and the top-loading pads can be changed without removing the wheel if necessary. All Formula calipers are post-mount, with a compliment of adapters available to fit both post-mount or IS frames and forks.
Rotor options: Formula offers the gamut of rotor options (all in six-bolt configuration), from the XC-standard 160 millimeter, right up to the full-blooded 203-millimeter DH rotors that we used for the majority of our testing.
Service kit: Formula's easy to use bleed kit is almost exactly the same as the SRAM/Avid system and the two kits are interchangeable, so Formula brakes can be serviced virtually anywhere in the mountain bike world.
Formula Rotors are among the lightest made, and a special stress-relieving process at the factory keeps them running true when superheated.
Race-testing The One brakes Initially we weren't that enamoured with the performance of the One's. After coming from brakes which were massively powerful but not particularly grabby it was a learning curve to deal with the bite offered by the Formula's, especially with the stock Sintered pads slotted into the calipers. It did take us a few weeks to get the best out of the brakes, but once there they provided impressive fuss and fade free stopping. The lever action is light, but positive and allows for good modulation of the power right on the point of locking the wheel which is essential for controlling speed. That said, the sharp nature of their power can initially lead to a loss of confidence as it's easy to lock the brake when the wheels are unweighted, for instance as the front wheel drops into a corner when you're leaned rearwards. You get used to the feel though and as with anything in racing, learn to use it to your advantage.
IRA in action: Formula sent our brakes with the optional IRA 'Instant Reach Adjustment' feature. The IRA replaces the stock threaded plunger and is an easy aftermarket fit should you feel that it's necessary. We were sceptical of how tough they would be, but as with the rest of the brake they stood up well to abuse. It took a big crash in one of the Windham rock gardens to take the first casualty, bending the adjuster totally out of shape and preventing any further use of it. Although damaged, the brake lever worked fine. In retrospect, this is an adjustment that's pretty much left alone once set so it isn't a hardship to do without.
The One calipers use easy-to-replace, top-loading brake pads. The sintered metallic pads, shown here, stop the hardest and wear the longest. Pinkbike tried the organic pads and went through them regularly in wet and sloppy race conditions.
FCS in action: Formula's Feel Control System is a feature that those who have, love, and those who don't have, desperately want. Depending upon where you choose to set your lever reach, the bite point of the standard The One brake can be quite far out. Providing a good range of adjustment, FCS enables you to key the bite point right where you want it. The FCS device compresses a small spring-loaded piston (actually, an O-ring) that diverts fluid from the brake hose. When the piston bottoms out the spring, the remaining lever stroke drives the brake caliper. Turning the FCS barrel compresses the spring, limits the stroke of the piston and thus affects the bite point of the brake system. FCS is simple and effective and tucked where it is unlikely to suffer untimely damage.
(Note: If you have small hands or like the brake to bite upon contact with the bar, you may still struggle as the brake lever design contacts the reservoir body just before the blade contacts the grip surface.)
Brake pad options: We tried The One brakes with both sintered metallic and organic pads (replaceable through the top of the caliper) and found that the organic was our preferred 'go to' pad as it exhibited less bite and more control, although this was at the expense of durability, especially in the wet. Wet conditions at Mont Sainte Anne took the life of several sets of pads thanks to the horrendous amount of mud on track leading up to qualifying and then just two runs of the Garbanzo track in Whistler was enough to take the life of another. We need to point out that, in both of these events, a kayak would have been more appropriate than a bike. Sintered pads are a must in wet, sloppy conditions if you are to expect decent pad-life and stopping power.
Set-up notes: Bleeding the One Brake is easy to accomplish, thanks to using the same fittings as SRAM. This means that a bleed kit is easy to come by, whether from Formula or the aforementioned SRAM. As with all brakes, it takes a little time to get perfect bleeding, but Formula's two-port system is definitely one of the more intuitive to work with – and we only needed to bleed the brakes once.
Comfortable lever blades combined with powerful one-finger stopping make The One brakes easy to control your speed with.
Pinkbike's take on Formula's The One DH brakeThe One is a lightweight, elegant looking and very powerful disc brake that is capable of spanning all manner of uses, from trail riding to World Cup downhill. Formula's DH brake is very powerful, yet once you're used to the feel, it is immensely controllable. What we assumed to be fragile instead proved to be tough and reliable. Those features, allied with superb support at the vast majority of large national and international races we've attended, are huge selling points. If you like your brakes without bite then you may struggle initially with The Ones, but as is true with all top downhill brakes, this is merely a case of recalibrating your senses. In fact, the only real criticism which we leveled towards was Formula's The One's inability to bring the bite point in close enough to the bar for riders with small hands, or for those who like the bite point right on the grip. This is especially true if you purchase the brakes without the FCS. We would recommend that, to get the best out of The One brakes, FCS is essential. If you are in the market for a pro-level brake and can afford about $400 per wheel, The One should surely be high on your list.
Check out all of Formula's options for The One brakes, as well as their entire lineup of brakes, suspension and wheels. Pinkbike has a put lot of time on Formula products, and we would enjoy hearing if you have had similar experiences.
From the information that I have got via internet, Pinkbike included I have never tested them due to price, I 'hear' that they are the best that money can buy. I see no reason why someone should complain about cost when he/she performs DH (way more expensive than XC).
Since we are talking about 'motors'. The best brakeset is a Brembo (also Italian).
The power is the best in class. The modulation is extremely consistent, but the modulation is shorter than other brake systems, which requires a readjustment in technique. I have used codes (lousy modulation, changed the lever/resevoir to elixr cr which was better modulation, but system weight was excessive, and still not as good as the formulas) , Elixr CR (not even close in power- moved to a trail bike), Hayes ACE (good for its era, but now eclipsed). I have also used the juicy line, 3, 5, 7, and ultimate- trail brakes, not appropriate for DH, HFX nines- no comment, and several hygia brakes- with careful bleeding equivalent to the juicy line but in fancy colors and at better prices.
If anyone likes the look of Formulas, but you're not so flush, check the Formula website out. Mine are pretty mint and frankly, in my couple of decades + riding experience, convincingly dick Avid, Hope, Shimano and Hayes brakes for light weight, powerful and consistent brakes. But my opinion is only worth as much as yours
bwaaaahahaha.... No seriouslly, i would wager that more than 60 % of dh riders are sporting juicys. perhaps you suck at bleeding brakes?
these ONE's are sweet looking brakes, but more than I want to pay for.... think Ill stick with the juicy 7s with the goodridge.. stops my demo 9 at 50 lbs pretty good.
The codes I had were the last generation. I haven't ridden the new ones. Seems like a pointless change to go from formulas to something else. If you are happy with codes, it would be pointless to change them also.
"However, the shortage of heat tolerance and rapid fadeout mean that the Juicy Seven Carbon is not a recommended full mountain brake."
You can find many reviews that say the same thing. This is consistent with my experience with the juicies as well.
fadeout?? i think you use your breaks too much .
Proper DH requires proper brakes, no amount of Know-it-all Normans (you know the type, 'I ride DH on a single speed, rigid with roadie tyres...blah blah, etc etc') will ever change that! Saints, Formula The One/Mega, Hayes Prime, etc....there's a reason these companies invest in separate R&D for DH brakes, they don't do it for shitz and giggles!
Saints 're fine by me
Only issue I have had is when the pads are down to 1/3 life left the lever reach is too cse for my liking even with lever adjust and pad contact adjust. I just replace em anyways.
Brakes I've rode in comparison and I'm 235 lbs so they got worked
Hayes mags, Hayes stroke rydes, Hayes nines and solos
Formula oro biancos, k-24s (still on my sxt) k-18s
Hope mono 4s and 6 tis
Avid codes, elixir crs, elixir 5, juicy 3 and 5
Ridden the ones in snow ice runs and 100 degree days on long descents haven't been left wanting
But like all things people have different tastes and braking styles so its good to have such a variety of stuff to choose from, these work for me and I know guys who love there saints and codes.
It's always good to hear the feedback of others but I don't think I have any issues with 'not riding the bike' or not 'laying off the brakes' enough, it's merely a case of conditions. And as it's something I found, it's something I shared - I won't be the only one to have experienced the same situation.
Having ridden RDS in the snow after a day of smashing out 8 or more Garbo's after 10 days of the same, on pads that were half worn when heading to Whistler, I am guessing you had a pad issue, either that or the poor shape of the rotors kill the pads.
Looks like the rotors are out of date and have to large a contact area, so don't clear the grime very well, causing excess wear.
Either that or you need to man up young pup and get off the brakes..... haha.... luv ya buddy.
There is no showing of my hand and there was no schooling although that's not to say I didn't benefit from the sheer amount of riding available in a condensed period of time. You clearly feel I'm wrong in my assumptions or unable to ride a bike. That's your perogative. However, I stand by the comments that Formula organic pads feel great, and in the dry or hot (disc temp, not ambient) they work superbly. But when it gets wet and the brakes haven't got much temperature in them they just run through too quickly. In the UK I've had similar life out of them in similar conditions - but given the average reader’s based on your side of the Atlantic it made sense to reference a situation they themselves could experience.
If you speak to other guys who were out in MSA you'll find they went through a fair few pads too. The pads I switched to were Sintered and they're still on the bike despite spending the rest of my time in Whistler on them and doing several days at Ft Bill since. On the brakes I was running prior to the Formula's (Hope V2’s) I was getting 4 months+ on average out of a set of Sintered pads and 3 months on the Organics but there was less of a transition in feel between the compounds compared to the Formula. Given that the Sintered last pretty well this points to the Organics being that bit softer. The Organics in the worst conditions just don’t seem able to get up to operating temperature properly, which as a result means the discs don’t dry off as well as they should and thus the grinding paste starts eating at things. On the faster stuff where you’re using the brakes harder you generate more heat in the system and it becomes almost self cleaning as the water quickly evaporates. Of course the added abrasives on the disc reduce the life of pads slightly but it’s water that usually proves to be the biggest evil, as was the case here.
I also found that, even when bled properly, that the pads ran very close to the rotors. Even the smallest imperfection in your rotor would produce rubbing.
Also, for Canadian residents, keep in mind that, at least two years ago, the Formula distributor in Canada was not a good distributor, so getting parts through your local bike shop was difficult. If you go with Formula's, in Canada, I would strongly recommend keeping your tool kit equipped with a multiple sets of pads, and full brake re-build parts (hoses & olives, master cylinders, etc) for emergency repairs, because there will be very, very few shops that will actually stock these items.
For these reasons, I got rid of my Formulas. I currently run Hayes Stroker Aces. They're pretty nice. They have their flaws too, but overall are a pretty good brake.
Also, with the new distribution channel in Canada (Lama Cycles out East, Trident out West and Formula Canada), the service/warranty and availability on small parts will be way better.
Thanks!
b) When I had the problem, because I couldn't receive local help, I had actually spoken directly with Formula USA. They explained at the time that they were aware that all of their brakes ran with the pads very close to the rotors. My comparison between the K24 and The One wasn't about power/modulation, etc, but simply a characteristic which was similar to all the Formula brakes at the time, according to Formula USA (not through personal experience).
c) Regardless of better distribution channels, shops still need to stock the items for repair. If I crash in practice, and need an emergency repair to my brakes, it doesn't help me if the distributor has stock, when the local shop doesn't. This is not a criticism pointed at either Formula or LBS's, but simply something people need to be aware of when purchasing higher end, less common brakes (would apply to Hope, Magura, Formula, etc.)
as for point c, I agree with you at 100%. I think it is only a matter of time until the small parts will be more availble in canada. As an example, lapierre, rocky and specialized spec oem formula brakes on their complete bikes for 2012. This means that it will be advantageous for many bike shops to carry a minimum of small parts. This means more chance to find what you are looking for in random bike shops. As for the racers, our race team carry lot of small parts and we also have 2 techs that know how to solve a brake problem.
cheers!
I do not care about torx vs socket head cap screws (SHCS). The torx size is the same as your brake rotors. The problem is the nitride coating!! When you snap one of these bolts -which you will -look at the fracture surface or the broken part. Notice that the depth of the coating compared the the thickness of the bolt. Coatings are hard, brittle and fracture easy under tensile loads. So, you have a thin but significant portion of the cross-section of your break mount bolt that is made of a brittle material. Hmmm...
The gold bolts ARE pimpin!! However, after I busted one of mine and looked at fracture surface under my microscope I swapped them all out for uncoated SHCS. I would highly recommend folks do the same or at the very least keep an eye on them bolts! By the way, stainless is the best option but you may have to order them online. Very cheep fix.
Ken
even though im scottish im big on the whole 'made in america' deal and the deal with superb craftmanship of the italians.
these brakes are bang tidy - theyr really light, and very powerful and my dad has some previos year wans on his rig and i quite like them
but i prefer a hope myself, especially the moto v2s fitted to my M3 (MY AMERICAN MUSCLE!) and they are even more beasted and i dont care about how heavy they are they get from 50-0 in about 1 meter (feels like that lol). i dont understand avids theyr balls, just get better stuff on ebay cheap instead of bollucks.
it was weird i found this strange kind of propaganda in a bike mag, it did a test on loads of brakes and avids and shimanos were the most powerful and they had V2s and The Ones on the test and they said they werent as powerful - they tested power using a computer and stuff but theres no way those brakes were more powerful than the big boys (its basic physics) but i know that was all fixed - they didnt even share results
Formula's after 3 months = 4 bleeds.
I know elixirs aren't the most reliable, but my RX's were something else!
And what's "tut tut"? Weird ass Brits.... (and piss take? I know you Brits like watersports, but that's not really "the thing" on this side of the world)... =]
Man, people are so lost from reality it's scary.
Maybe you have been taking in too much Methane from your little secret Brazillian fetish you have? Or maybe your nasals are clogged from all those "German" activites you do. Theehee.
Come on mate, I'm giving you a hard time Sackio. Buy some looser panties or do whatver it takes to relax a bit.
