This cap is fitted at the housing end, where the outer casing meets a cable stop or derailleur, not at the loose end of the inner wire, which is a separate component sold in a different bottle size for that purpose. The two are not interchangeable in size, since the outer housing cap is shaped to grip housing wall thickness, while an inner-wire end cap is far smaller and only meant to stop wire fraying.

A bottle of 100 outer caps suits home mechanics doing multiple bikes and small workshops, since a single shift housing run typically uses just one or two caps per replacement. For most riders doing their own bike maintenance, this quantity comfortably lasts several years of housing replacements and cable rebuilds across multiple bikes.

No, the Red, Black, Gold, and Blue variants are identical in size, material, and fit, and are offered purely so you can colour-match your cable housing, frame, or components. All four are made to the same specification for wall grip, corrosion resistance, and long-term durability.

Yes, these caps are sized to fit standard-diameter shift cable outer housing used across derailleur-equipped road and mountain bikes sold in India, including OEM and most aftermarket housings. If your bike uses an unusually thick or thin housing, it is worth test-fitting one cap before crimping the rest of the bottle.

Yes, DoGoodCo supplies this as a genuine LeBycle component, machined and finished to a consistent size and grip quality across every cap in the bottle, so you get a reliable crimp fit every time.
