Abstract
A control device for a hydraulic brake for a bicycle includes a reservoir for hydraulic fluid. The reservoir has a variable volume. The control device also includes a reservoir cover at least partially defining the reservoir, and a support that is attachable to a handlebar of the bicycle via an inner annular surface of the support. A handlebar proximity zone is radially outer relative to the inner annular surface of the support and is within two centimeters of the inner annular surface of the support. At least part of the reservoir cover is within the handlebar proximity zone.
Claims16
A brake control device for a bicycle, the brake control device comprising:
- a housing including a support that is configured to be attached to a handlebar of the bicycle via an inner annular surface of the support, the inner annular surface defining a clamp surface axis and a clamp plane, the clamp surface axis extending longitudinally along the inner annular surface and the clamp plane being perpendicular to the clamp surface axis and intersecting the inner annular surface, wherein a handlebar proximity zone is radially outer relative to the inner annular surface of the support and is within 40 millimeters of the inner annular surface of the support;
- a reservoir for hydraulic fluid, the reservoir being within the housing, wherein the reservoir is within the handlebar proximity zone and does not intersect the clamp plane;
- and
- a pivot for pivotably attaching a lever to the housing via the pivot, the lever being pivotably attached to the housing via the pivot and the lever being pivotable relative to the housing via the pivot about a pivot axis;
- wherein the pivot axis is within the handlebar proximity zone.
