Formula Brakes The One Disc Brake System
Product DescriptionReady for duty on World Cup DH rigs or keeping speed in check at the next Downieville Super D, the Formula The One Disc Brake offers maximum versatility and power in an ultralight package package that's hard to believe. The secret ingredient of The One Disc Brake is a one-piece (The One, get it) caliper with two 24mm opposing pistons. That's almost an inch per piston. The big pistons mean huge stopping power. In fact, they represent a 19% increase in surface area over the Formula R1 brakes. Big power doesn't mean heavy. The One still only weighs 336 gramsAAArivaling most XC brakes.The added braking power is great for bigger or more aggressive riders, and legendary Formula modulation means constant traction and control. The pistons themselves are made of a heat-dissipating composite material and are cupped to provide even more fluid to regulate heat. The one-piece design is stiffer because there are no bolted-together parts to flex along the seam line when you grab a finger-full of lever. The caliper provides good ventilation on both the bottom and top for the pistons and pads to vent heat. The top vent also helps make pad changes easy, even with the wheel still in the bike.Moving upward, The One uses a standard woven polyester hose that is super light, but still prevents hose expansion from heat. This keeps the brakes feeling stiff, even as the caliper heats up on big descents. Formula uses DOT 4 brake fluid because of its resistance to thermal expansion, gas absorption, and the quality control inherent with DOT-approved products, no matter what brand or where you get it.The hose attaches directly to the new Feeling Control System for quick and easy adjustments of lever stroke and to compensate for pad wear. A forged aluminum, radial master cylinder offers excellent power transfer due to incredible stiffness, and strength.

a All Mountain Rider Date Reviewed: August 8, 2012 Strengths: -Lots of stopping power. -One finger braking (no stress on the finger like other brakes such as formula r1 or rx). -Lightweight -Looks damn good! -Very good modulation. Weaknesses: -Adjustment. Just like the RX and R1's... PITA to adjust the rubbing rotors. I want to give up on this brakes already. Shimano's SLX are a lot easier to adjust. -brake pad adjustment on the lever doesn't really work. -Intermittent noise in the front with formula rotors when brake is engaged. -expensive Bottom Line: Expand full review >>Favorite Trail: Demonstration Forest Duration Product Used: 150 miles Purchased At: Mikes Bike Similar Products Used: 2012 Shimano SLX Bike Setup: 2012 Expert Carbon Evo

matthew melvyn Date Reviewed: May 6, 2012 Strengths: Strong, Light,,,,did I say strong. People have mentioned lack of 'feel' but I don't see that, they modulate fine for me. Pretty bullet-proof, more of a fading than a fail when you need to work on them. Weaknesses: Difficult to maintain, as in the most difficult disc brake system out there that I ever worked on (by far). Finicky. Pads not in most shops, so you better count on toting a few around with you Bottom Line:

from Saratoga Springs Date Reviewed: June 30, 2011 Strengths: Unbelievably power from such a small lightweight package. Modulation is amazing. Love the minimalistic design and asthetics. Customer Service Weaknesses: The clamp between the left and right levers are the same so they aren't symmetrical (nothing performance wise wrong with this) A bit of turkey garble on the rear, but nothing to write home about. Pricey.
