Seller's description

Please read before purchasing:
All mirrors as shipped will require some final adjustment from the purchaser to adequately fit your Sunglass, Helmet, or Ball Cap. Instructions for fitting your mirror to your helmet, sunglasses, or ball cap are included with each item. If you need help with fitting your mirror, I am here to answer any questions please ask.

Why would you want to buy a rear view mirror? In May 2014 The League of American Bicyclists published a study of cycling deaths between February 2011 to February 2013. The organization sifted through hundreds of cases from across the country. Using newspaper and television reports and blogs, they were able to get a closer look at 628 individual cases and tease out some patterns. In 40 percent of the cases, the victim was struck from behind. When properly adjusted, a simple twist of the head from 10 to 15 degrees is all that is necessary to see what is behind you.

Which model of mirror is best for me?

*The Ball Cap (Rowing) Model comes in Right or Left hand models. It attaches to the brim of the ball cap and allows you to see behind you. Great for walking along roads, bike paths, and rowing.

The Helmet Model:
Is lightweight, has a high quality mirror, and is made from a 14 straight gauge bicycle spoke so it will mount securely, offer good visibility, and not vibrate. The Helmet model is well suited for people with prescription eyewear, especially those with lightweight glasses or if you have a pair of expensive sunglasses such as certain Oakley's that can have exotic temples. Using the Helmet mirror, you are not limited to which pair of glasses you wear, you can even go without glasses for those long slow up hill climbs in summer when the sweat just pours from your eyes.

*The Helmet mirror comes in 2 mounting sizes, Standard and Large. The Standard size fits most helmets sold in Bike shops that have a rim width up to 1 1/4 inches or 31.75mm wide. The Large size will fit helmets that have rims that measure between 1 1/4 to 1 1/2 inches or 38.1mm wide. Before ordering a helmet mirror please check your helmet rim for the width.

The Sunglass Model:
Has a high quality mirror, made from a 15 straight gauge spoke so it is lightweight, will mount securely, and offer good visibility. The sunglass model was designed to fit 90% of sunglasses made today. The ideal glasses are ones that have a rectangular temples similar to the pair in the above images.

*The Sunglass model comes in Left and Right Hand styles. The normal is the Left Hand Style which places the mirror on the left or traffic side of the glasses. If you live in an area where the cars drive in the left lane, your right is dominant, or you have lost the sight of your left eye choose Sunglass Right Hand and I will make the mount to fit the right side of your sunglasses.

One advantage the sunglass model has over the helmet mount is if you have the helmet mirror set for warm weather riding and is gets cool enough to wear a cap or balaclava under the helmet, the helmet mirror won't give you the same view behind as it did before, so you may have to readjust it. Or buy 2! You can never have enough...

Set it and forget it! There are no moving parts in the Flatlander Bottle Cap Mirror, once the mirror is fitted to your sunglasses or helmet, unlike most mirrors today it will retain its setting so it can be removed and reinstalled without having to re-adjust it.

Custom Bottle Caps!
You can have a custom bottle cap made with almost anything on it. If your club has a special event you can have custom bottle caps made for it, or you can have that special person's picture. Just click on the link below to go to my other listing.

Wait! You Don't Have the Cap I Want!
I have a very large selection of bottle caps both soda and beer, so if you have a favorite ask me and I will substitute it for you.
