Patent number: 8172247Abstract: A bicycle handlebar assembly that includes a number of grip sites, forearm supports, and a number of structures that have airfoil shaped cross-sections and that provide a highly adjustable handlebar assembly with improved aerodynamic performance across the range of adjustment of the handlebar assembly. The handlebar assembly includes a pair of shim stacks that each includes a number of shims that are selectively mountable to the handlebar assembly to adjust a relative vertical height of left hand and right hand aerobars and arm pads. The aerobars and arm pads are secured to the handlebar by way of corresponding clamping assemblies such that the aerobars and arm pads are movably secured to the handlebar assembly to provide the highly adjustable aero handlebar assembly.Type: GrantFiled: July 1, 2011Date of Patent: May 8, 2012Assignee: Trek Bicycle CorporationInventors: Jennifer Weber, Douglas A. Cusack

Patent number: 8056987Abstract: A quick release assembly for a bicycle wheel that includes a pair of heads disposed at generally opposite ends of a skewer rod. One of the heads includes a cam surface that is translatable relative to the head. The quick release includes an operator having a handle portion and a stem portion. The stem portion includes a cam that cooperates with the cam surface formed in one of the heads such that operation of the handle alters the distance between the heads from a first orientation wherein the heads secure a wheel to a bicycle, a second orientation wherein the heads loosely secure the wheel to the bicycle and a third orientation wherein the wheel assembly can be freely removed from the bicycle.Type: GrantFiled: April 8, 2010Date of Patent: November 15, 2011Assignee: Trek Bicycle CorporationInventor: Douglas A. Cusack

Patent number: 8042823Abstract: A bicycle seat post assembly that dampens movement between a seat and a bicycle frame. The seat post assembly includes a seat post, a collar that passes through the seat post, and a dampener that is disposed between the collar and the seat post. The collar is pivotably connected to the seat post so that the collar can rotate relative to the seat post. The collar rotates about an axis that extends in a crossing direction relative to both a longitudinal axis of the bicycle frame and a longitudinal axis of the seat post.Type: GrantFiled: January 6, 2010Date of Patent: October 25, 2011Assignee: Trek Bicycle CorporationInventor: Douglas A. Cusack

Publication number: 20100225090Abstract: A bicycle structure having a truncated airfoil cross-sectional shape oriented in a direction generally transverse to a longitudinal direction of the bicycle structure. The truncated shape has a generally rounded head, a pair of opposing sidewalls that extend from edges of the rounded head, and a blunt rear facing end wall. The blunt rear facing wall is maintained in a spaced relation so that a tail portion of overall airfoil shape is formed by air associated with the flow of air over the truncated airfoil cross-sectional shape.Type: ApplicationFiled: March 6, 2009Publication date: September 9, 2010Inventors: Douglas A. Cusack, Paul Harder
