Consistent shifting – thanks to chamfered inner plates
Chamfered inner plates align with HG sprocket profiles to guide the chain during shifts, reducing the chance of hang-ups and misalignment. The HG series geometry helps chains seat cleanly under load.
Cleaner, more accurate gear changes under pedalling load, making indexed shifting feel more positive and reducing missed shifts.
Quick installation – with a connecting quick-link
A dedicated quick-link allows the chain to be joined or removed without specialised tools, simplifying maintenance and repairs. A 116-link length provides room for common on-bike shortening.
Tool-free joining speeds up roadside fixes and routine cleaning, so downtime is limited and maintenance is less fiddly.
Improved wear resistance – thanks to heat-treated rollers, pins and plates
Heat treatment hardens contact surfaces where the chain engages sprockets and rollers, reducing abrasion and resisting deformation over time. Hardened components maintain tolerances longer under regular use.
Longer service intervals and steadier performance for riders who cover regular mileage without frequent chain replacements.
