Installing a C-series Spurcycle Mirror
These mirrors are intended for flat bar bicycles and can be mounted on either or both sides. Equip yourself with a 2mm and 4mm hex key, then follow the simple steps below. Once you've ridden with a mirror, you'll never want to be without.
Remove Bar Plug
Remove the original bar plug from your handlebar.
If you do not have a grip with removable bar plug, then the end of your grip must be modified or the grip replaced with a model that does allow access to the end of your handlebar. Your local bike shop will be your best resource.
Insert Expander
Insert the Spurcycle Expander assembly in place of your original bar plug and push the Mirror Arm to rest flush against your grip.
Position Mirror Arm
Rotate the Mirror Arm so it is parallel to the ground or tilted slightly upward. It is not designed to be angled more than about 20 degrees from horizontal.
Tighten Expander
Tighten the Expander Bolt by turning clockwise using a 4mm hex key. The Arm should firmly resist rotation once tightened. Still, there's no reason to "crank it down".
Adjust Mirror Angle
Final adjustment of the Mirror angle must be done while on the bike in a riding position. We suggest placing the reflected horizon at the center line of the Mirror.
Secure Mirror Angle
If needed, the Mirror angle can be further secured by tightening the Socket Set Screw using a 2mm hex key. Be careful not to overtighten though (max ~0.5Nm). The Mirror should be snug but adjust smoothly, firm enough to resist bumps in the road but easy to tune while riding.
Installation Options
Spurcycle mirrors are symmetric by design and can therefore be mounted on either or both sides of a bike. Below are some additional steps to convert a stock mirror from left-side mounting to right-side.
Loosen Set Screw
Loosen the Socket Set Screw completely. Remove and set aside.
Extract Mirror
Extract the Mirror and Socket Sleeve from the Arm and Expander assembly. This takes a little effort, because the Socket Sleeve has a small catch feature to hold it in place. Don’t be afraid to pull firmly.
Flip Arm and seat Mirror
Orient the Arm facing forward on your "other" side. (In this case, we've gone from the left side of the bike to the right side. What was the top of the Arm should now be the bottom.) Align the slot of the Socket Sleeve with the inner tab, then press the Mirror with Socket Sleeve inward until it seats fully—making an audible snap.
Reinstall Set Screw
Reinstall the Socket Set Screw and tighten lightly using a 2mm hex key.
Now proceed through standard mounting steps above.
Other notes...
Effective riding with a mirror takes some getting used to. Expect to spend a half dozen rides gaining proficiency. Of course, don't forget to maintain your attention on the road ahead.
Keep your mirror clean of dirt and fingerprints just like you do your sunglasses.
Spurcycle Mirrors are designed to dislocate in case of significant impact to protect rider and product. The above process can be used to reinstall after dislocation.
Replacement parts are available as needed.
