901 & 903 Mirror
The Cycle Star 901/903 handlebar mirror from Busch&Müller either plugs into the end of your handlebar, or wraps around the bar, whichever you prefer. The 5.5 " gently curved arm is best for positioning the mirror well to the side or high above the handlebar. The mirror comes complete with the hardware pictured below. 901: 55mm diameter. 903: 81mm diameter.
The 901/2 and 903/2 plug into the end of a handlebar. On my road bike, a Rivendell Rambouillet, I don't have bar end shifters, so the bar end is free for a mirror. I use the 901/2. It's perfect for me.
The 903/7 can fold flat. 80mm flat mirror. Bar end mount only for any upright handlebar on regular bike or E Bike. The slightly convex mirror gives you a wide view of the road behind. Offers a wide range of adjustment. There is a ball joint at both ends of the arm, and the base can pivot on the mount.
