Hummingbird Pannier Performance: Fundamental Load-Carrying Designs

(These are the designs that enhance touring bicycle handling through exceptionally high pannier stability, highly precise gear distribution and extraordinary reductions in pannier weight)

ATS Ultra-Lock Four-Point Mounting System (IFT pannier models: most stable of all pannier mounting systems)
RBD Four-Point Mounting Systems of many designs (RP pannier models)
RBD Four-Point Adapters (extremely high pannier mounting stability in non-ATS racks)
Widely spaced (up to 9.5") upper and lower mounting hooks (RP models)
Widely spaced (up to 8.5" top and 5.5" bottom) pannier mounting fasteners (IFT models)
Reinforced tubular aluminum internal pannier frames (IFT: internal frame technology) for extreme pannier stability
Dual- and triple-relieved aluminum plate stiffeners (weight reduction)
Extruded HDPE pannier load supports (pannier load-bearing stability)
Dual compression / stabilizing systems (high pannier stability)
Vertical, lateral and fore / aft, in-pannier gear loading design
Panniers available in three vertical sizes (pannier width reduction)
Panniers available with variable (2.0", 3.0", 4.0", 5.0") inner compartment widths (narrowest pannier design)
33/67% or 55/50% zip-out vertical primary compartment dividers (gear distribution)
Rear stiffening plate of 100% support (RP models) to create highest levels of pannier / gear stability
Rear aluminum tubular frame of 100% support design (IFT pannier models) to create highest pannier stability
Five-fabric construction to greatly reduce pannier weight

Extraordinarily high performance-to-weight ratios: panniers as lightweight as 18 oz. per pair
