The Ciamillo  B1 Ultra feature an 8mm extension on the legs that hold the padholders and stiffer side ribs to support the extension. This caliper allows direct fit to  Brompton folding bikes without the need for an adapter. The cable routing is from the bottom and left and features two longer titanium centerbolts.

New for 2024, thicker carbon plates, increased power, and newly designed centerbolts and barrel adjusters. The B1 Ultra are single-pivot high-performance super-lightweight road calipers with carbon fiber truss architecture.

Includes front brake and rear brake with padholders and full titanium hardware. Brakes come with Shimano compatible padholder geometry - * Does not include pads.

Calipers are made from Grade 5 titanium, 7075 aluminum, and carbon fiber. These material optimized parts in the new B1 allow not only the lightest road caliper ever made but also the smallest. The compact architecture provides an inherent stoutness and rigidity as well as improved aerodynamics. They offer generous clearance for larger tires.
