Abstract: A gear set arrangement (10) for a bicycle gearbox (400) includes a planetary assembly, a stationary component (24), a first and a second brake (B1, B2), and a first and a second freewheel clutch (F1, F2). One planetary gear set (12) of the planetary assembly includes a first rotary element, a second rotary element, and a third rotary element. The first rotary element is rotationally fixable on the stationary component (24) by the first brake (B1). The first rotary element is connectable to the output (36) by the first freewheel clutch (F1). The second rotary element is rotationally fixable on the stationary component (24) by the second brake (B2). The second rotary element is connectable to the output (36) by the second freewheel clutch (F2). The third rotary element is connected to the input (34) for conjoint rotation. The gear set arrangement (10) is configured to provide three ratios.

Abstract: A method of repairing a manufactured component having a damaged area including: laying a preformed thermoplastic polymer repair patch over the damaged area; heating the thermoplastic polymer repair patch to easily and quickly deform said patch to said damaged area; and bonding said composite patch to said damaged area of said manufactured part. The thermoplastic polymer repair patch including an adhesive layer and a thermoplastic polymer selected from acrylic-polyvinyl chloride, polyethylene terephthalate glycol-modified (PETG), high impact polystyrene, polyvinyl chloride, and high density polyethylene.
