Product DescriptionTipping the scales at approximately 289.7g for an entire post mount assembly with a 160mm rotor, the powerful Formula R1 Disc Brake is just as at home on a purebred crosscountry race rig as it is on an all-day enduro ripper. It shares the same flex-resisting and heat dissipating technology as the superlight weight R1 Racing, but the R1 divvies up the classic price/weight/strength ratios to favor cost and reliability over grams.A forged master cylinder ensures strength at a low weight, while a radial design resists flex so all lever forces are transferred directly to the hard anodized piston. A new, higher capacity master cylinder houses time-proven DOT 4 fluid to keep things operating cool and smooth for long maintenance intervals. You can easily run the levers moto-style without swapping lines thanks to Formula's Flip-Flip design. It?s also compatible with the MixMaster clamp to reduce cockpit clutter by merging shifter and lever clamps into one unit.The R1 is equipped with Formula's Tool Free Reach Adjustment knob for quick and simple fine-tuning of lever position to get you set with perfect ergonomics and maximum leverage. The R1 can also be upgraded with the separately available FCS (Feeling Control System) that allows lever stroke adjustment and compensation for pad wear.The R1 uses a polyester braided hose with aluminum crimps and banjo fittings to prevent hose expansion when under extreme compression. The one-piece, forged caliper houses a large 22mm diameter piston that pushes an aluminum backed organic brake pad. This combination provides excellent power, modulation, and quiet operation.The Formula R1 Disc Brake represents the pinnacle of disc brake performance. The price reflects all the parts, save the rotor, for a single wheel. Rotors are sold separately with the appropriate adaptor?choose between one piece 160mm or 180mm, or the slightly lighter and much sexier two-piece design in 160mm or 180mm.Please note: almost all hydraulic brake lines need to be cut to size before a bike is properly shod with hydraulic disc brakes. You'll need a quality cable-cutter like the Park CN-10 and a spoke to first cut and then de-crimp the housing.
How does it look? Hawt! The lever has a very clean, minimalistic lines with red anodized clamps and hardware. The master cylinder itself sports a flat black finish and is complemented with a silver forged lever. The cable is an elegant gray kevlar braid which leads to a flat, textured caliper with red ano accents as well. However, the rotor itself is not of the same aesthetic caliber. The swoopy center lines are abruptly finished by a very round outer rim peppered by dozens of holes. It’s not in the same vein as the classic Oro Puro rotor. Continue reading →

Strengths: Lightweight, good modulation, good stopping power
Weaknesses: Leaks toxic DOT 4 fluid onto handlebars, terrible customer service
Fast forward two months, and halfway through a cross country race my rear brake was losing power. By the end of the race the brake had almost no power at all. I took the bike to the shop the next day to get the brake bled, but the shop called me a few hours later to say some membrane was leaking on the back of the master cylinder after they bled the system and my carbon bars were once again covered in toxic, corrosive DOT 4 fluid.
Not only did I have to replace the carbon handlebars at my own cost, but the Formula warranty people initially mailed us the wrong part. My BS meter started going off, so I bought other brakes to ride in the meantime (Shimano XT) and let them try to figure out how to solve the problem. Finally, we just shipped the brakes to Formula for repair, and lo and behold, they claimed that it wasn't their fault. Even though I never bled or serviced the front brake, they claimed that BOTH brakes had been contaminated somehow, and were therefore not reparable under warranty. I consider it lesson learned, and hopefully others won't have to suffer the same fate.
Avoid Formula products!
P.S. I feel like this is a lawsuit waiting to happen--their brake leaks corrosive fluid onto handlebars in a spot that's not visible from the outside. This has been well documented (google Formula brakes on carbon bars). Somebody is going to have a bar break off in their hands right at the compromised location and hopefully they don't get badly injured, but the fact that they don't have a recall or at least a public notice not to use these on carbon bars seems criminally negligent.

good power with third-party semi-metallic pads;
Weaknesses: unreasonably high replacement parts and components price;
terrible customer and warranty service;
absence of regional tech support;
low power with stock pads;
squeaking with stock rotors and pads;
gap between pads and rotors is very tight and hard to adjust.
until levers started to leak. first it was some slurping noise from the left lever, then braking power loss for the front and finally some liquid running from the bottom of brake lever. btw, that liquid completely ruined my carbon handlebar coating.. at MTBR forum I've read about that issue isn't rare and most of pre-2010 R1 models had leaking levers from the start. Formula makes replacement or repair of whole brakes free of charge because it's warranty issue.
ok, I had to remove brakes from the bike and tried to contact Formula office same day. their european office was hard to reach by phone, I've used about two days of constant calling to get retorted with "contact your regional dealer for support". then I've written some emails to italian office and local ukrainian office but got no reply. then called local representative several times but they told me Formula did not supplied them replacement parts and I have to purchase them directly. I've received a single reply by email from Italy where they promised to contact local representative for information. then no replies, no answers, nothing for about 3 weeks. last call to local representative finished with pointing fingers to Formula main office again.
conclusion. R1 brakes tries to hit premium segment by it's price but Formula provides no support to customers. when something happens with your pricey brakes then your requests will be simply disregarded. take money and keep silence - is an exact "formula".

Strengths: Good initial power and feel
Weaknesses: Extremely noisy, can't hold a conversation with a fellow rider on the climb. Have been into the shop at least 4 times with new rotors, pads etc. I'm now finding they fade on stepper downhills of more than 3Km and get more noisy as this happens. They are not good performers in the wet. They came with my Lapierre Zesty and I have now just bought some Shimano XT brakes and will get rid of them after less than a year. Very frustrated!

Strengths: - Extremely light (dropped considerable weight by replacing my Hope M4's).
- Great modulation, with really good feel at the lever.
- 160mm Rotor easily powerful enough on a 26er (not so much on a 29er).
- Easy lever adjustment.
- Simple, intuitive bleeding.
- Look great!
Weaknesses: - 160mm on the front isn't powerful enough for a 29er.
- Delicate master cylinder.
- Pretty expensive (but you get what you pay for).
- Cant adjust lever firmness (position yes, firmness no).

Strengths: lightweight; good stopping power
Weaknesses: the lack pad clearance is absurd - a real pain in the ass unless you like rubbing & squealing. From the beginning the inboard pistons refused to retract fully. After a year of dealing with these, constantly getting even the tiniest deflection out of my rotors, constantly readjusting calipers, I sent them back to Formula - they replaced the piston seals, which supposedly helps bring the piston back in, as the seals supposedly stay seated on the piston edge and the cylinder wall, and the seals supposedly stretch as piston is forced out (lever squeezed) and when that potential energy put into the stretch of the seal is released (as the master cylinder piston pressure is released when letting go of lever), supposedly the seal takes its original shape back, drawing the piston back with it (I don't know what % this retractive force of the seal contributes to pulling the pistons going back in - I'm quite certain the main force pressing the pistons back in is still atmospheric pressure from air molecules slamming at 14.7 psi against pistons; this "seal" seating is btw why Formula will tell you not to lubricate the pistons with anything but brake fluid, not that I ever did that, but brake fluid is pretty slippery itself, so I have some doubts about the whole seal deformation theory, but I'm not an expert.) Anyway, guess what: after getting R1's back from Formula, there was very little difference - the front was somewhat better, maybe 0.1 mm gap between rotor and pads, but that with pads maybe 1/3 worn down, and the rear brake has only maybe 0.01 mm, ie, no clearance on inboard side - forcing the caliper to be set so that the caliper body is about one micron from rotor - so of course guess what I hear on cornering - the sickening sound of rotor squealing on caliper body.

Strengths: Great stopping power, fantastic feel. I crave brakes with good modulation, and this is by far the best I've used so far.
Weaknesses: Pricey (but in this case you get what you pay for). Adjustment is tricky because of the low clearing between calipers and disc. With my second set of brake pads (Swissstop brand instead of original Formula) the brake improved (even better modulation, adjustment got easier).

Strengths: Very strong, well modulated, light brakes. They don't fade. They are strong wet or dry. Pads very easy to change. Reach adjust works perfectly. Bleed it straightfoward.
Weaknesses: Would like some control over stiffness, no adjustment for modulation (although there is plenty of reach adjustment)
Little noisy even with organic pads
Had to replace rear pistons due to sticking piston on one side, but, bought used, have no way to confirm the prior history of these brakes

I just got back from Outerbike where I got to ride a lot of bikes. I really wasn't there to evaluate brakes, but I did ride a couple of bikes with Formula R1 brakes and they really stood out to me. I'm not one to nitpick components a lot. All the other brakes on the other bikes were fine. It's just somehow the R1's really impressed me. I'm sure some of it is personal preference, but they just fit right (I have relatively small hands) and had real nice modulation.
I've got no plans of replacing something that's not broke, but my next bike will have Formula R1's or something very similar.
