Jagwire POP End Cap

These end caps act as reducers, designed to bridge the gap between standard frame mounts and modern compressionless brake housing. They ensure a secure fit on frames or calipers that aren't natively compatible with that specific housing type.

Yes, these are designed for 5mm brake housing. Their specific function is to adapt that housing to fit into frame stops or caliper mounts that might otherwise be too large or require a different interface.

High-performance braking systems, especially those using compressionless housing, create significant tension. The durable alloy construction of these caps prevents the housing from deforming or blowing out under that stress, which helps maintain a consistent, responsive brake feel.

Each pack contains 10 end caps, which is typically enough to outfit a full bike's braking system with spares left over.

No, these are specifically engineered for brake systems. Shifting housing and brake housing have different diameters and compression characteristics, so these caps are not interchangeable with derailleur cable components.
