25th Anniversary T1 Limited Edition Brake

It might not be apparent as a static image in cyberspace, but the inboard routing found on this 25th Anniversary T1 Brake plays a larger part in aesthetics than Formula's Limited Edition chromating finish and laser etching.

Instead of a caliper/hose junction at the outside, Formula relocates the T1's to the inside for shorter, more direct routing on modern front and rear post-mount standards. But, that's not to say the opposing 24mm-pistons hiding behind an anodized-red cap isn't going to go unnoticed.

Due to that, others are sure to recognize the downhill-stopping power packed into this svelte package. In fact, those pistons represent a 19% increase in surface area over Formula R1 brakes. With the T1, however, big power doesn't mean heavy. The T1 still weighs less than 340 grams (a number that rivals most XC brakes), making them an excellent choice for everything in-between.

Added power is great for aggressive riders -- legendary Formula modulation, on the other hand, means constant traction and control. Or, in other words, what racers and competitive riders actually need. The pistons themselves are made of a heat-dissipating composite material and are cupped to provide even more fluid to regulate heat.

They're housed in a one-piece caliper design that's stiffer than two-piece alternatives because it's void of bolts and a seam. A large top-load pad design helps vent heat, and also simplifies pad changes. Moving upward, The T1 uses a standard woven polyester hose that's ultralight, yet it still prevents expansion from heat. This keeps the lever feeling consistent and reassuring, 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. The hose attaches directly to Formula's Feeling Control System for quick and easy adjustments of lever stroke, and to compensate for pad wear.

A forged aluminum, radial master cylinder provides excellent power transfer due to incredible stiffness and strength. Formula also specs The T1 with its Tool Free Reach Adjustment knob for quick and simple fine-tuning of lever position. A two-bolt clamp affixes it to the handlebar, and you can run the T1 regular or moto-style.

Either way you hang the levers on the bar, there will be an accessible bleed port near the clamp. The 25th Anniversary T1 Limited Edition Brakes does not include rotors or adapters -- these are sold separately. It comes pre-bled as a 100mm-length front or 165mm rear.
