The Cycle Star 80 is B&M's premium 80 mm bicycle and e-bike mirror: diminishing shatter-protected glass, an internal bar-end mount, and a choice of mirror-bar lengths and mounts. Pick the version that suits your handlebars.

Highlights

• 80 mm diminishing (convex) glass with shatter protection — over 75 % more field of view than the 60 mm Cycle Star
• Six versions: 13 cm, 6.5 cm, 5 cm or no mirror bar, a bracket-mount 6A, and the heavy-duty impact-joint 903/7
• Folds in on impact; adjusts in every direction
• Approved for speed pedelecs in Switzerland
• Internal handlebar mount, 17.2–20 mm bore (6A: 14.5–18.5 mm)

Which one

903 for the longest reach clear of bar bags and grips; 903/1 and 903/3 for a tidier medium and short bar; 903/2 only on swept-back bars; 903/6A for bracket mounting or thinner bars; 903/7 on e-bikes where a knock is likely.

Fitting

Internal handlebar mounting: the aluminium expander plugs into a bar end with a 17.2–20 mm inside diameter (B&M part 401/2SHPB or 401/3SHPB adapts smaller bores). Fits left or right unless stated. Remove the bar-end plug or grip end first.
