State Bicycle Co. 4130 Road v2 Brakes: Read the 55–72mm Caliper Reach Record
State Bicycle Co. 4130 Road v2 brakes are listed as dual-pivot alloy calipers with 55–72mm reach. That reach entry belongs to the caliper record, not the rider’s reach to the handlebar. Identifying the documented brake arrangement is a different task from deciding which replacement part will fit an individual bicycle.
Identify the State Bicycle Co. 4130 Road v2 brakes
The product specification names dual-pivot alloy calipers. The PDF’s detailed brake entry uses the wording “Dual Pivot, 55-72mm” and “Forged Alloy”. These descriptions establish the recorded brake type and material label. They do not provide a complete caliper part number, a pad specification or a procedure for setting the brakes.
Keep the 55–72mm range with that caliper description in an enquiry. An isolated “reach” number could otherwise be confused with frame geometry, a handlebar dimension or a control adjustment. The cited specification does not give a method for measuring the installed assembly, so this reference does not turn the range into an installation test.
Keep the lever and wheel records in scope
The PDF names hood brake levers. That description helps distinguish the recorded road controls from a flat-bar build, but it is not a lever-pull compatibility table. Do not expand the wording into approval for an unspecified lever or another caliper simply because both descriptions use familiar road-bike terms.
The linked Road v2 is the relevant native example for this rim-brake record. A State All-Road model’s hydraulic-disc description would answer a different equipment question. The catalogue listing is State Bicycle Co. 4130 Road v2 - Black & Tan - (8-Speed).
Prepare a precise identification question
The product’s wheel record specifies quick-release hubs with 100mm front and 130mm rear spacing. Those are hub entries, not caliper-reach values. Keep the brake description and wheel information in separate fields when explaining the bicycle to a parts supplier; sharing a model family is not enough to collapse the two into one measurement.
Before discussing a replacement, identify the actual bicycle and any component markings that differ from the published record. The source does not supply a brake test, stopping-distance result or disc-conversion approval. The historical Contender image also cannot verify the brakes fitted to a Road v2 being offered.
The established State pages provide broader family context for the named brake arrangement. State Bicycle Co. topic; existing State introduction.
