R50 Mirror
We believe in mirrors like we believe in bells. Ride with one for a week and you'll never again want to do without.
Our R-series is available in two mirror sizes to fit drop bar bikes, a 35mm and a 50mm diameter. They both provide a very similar view but the smaller mirror is more challenging to use, a tradeoff for the sake of minimal form. We consider the R35 our "pro" (vanity) mirror and the R50 our everyday touring model.
Designed to complement a modern drop bar bicycle. Not compatible with extreme bar geometries or positions. Some Enve bars and others without standard bar plugs also may not work. Email photos of your setup if you have any questions.
Why ride with a mirror?
Mirrors enable a safer experience by providing a more comprehensive view of other road users. This extra awareness also extends social cohesion on group rides and can be leveraged for strategic advantage in competition. Any of these benefits alone might make a mirror worth the money. Together they will transform your riding experience.
What makes a Spurcycle mirror so good?
From the perspective of dedicated cyclists, we've given the humble bar-end mirror comprehensive R&D attention. The slim, streamlined designs from Spurcycle connect all the dots: form, function, and durability—even affordability. Like with our bells, the goal has been to make something "simply better".

GREAT MIRROR, PERFECT FOR COMMUTING AND AVOIDING LARGE VEHICLES. THANKS
Love the engineering, wishing mirror were larger in ID.
I ordered the larger of two options but when it arrived I knew it'd be too small to use. So I took the mirror out of its frame, took a larger mirror (another manufacturer's) & cut the plastic mount off the back, then used some plastics-compatible epoxy to marry the bigger mirror to the base of the smaller one I received. Works GREAT and the positioning engineering of the R50 mirror is vastly superior to what I'd been using.
This glass mirror is so much clearer than a plastic mirror. No shake, and easy to see what's approaching from behind. I prefer the 50 mm model, which provides a wider field of view.
Second one for another bike, It's a great product that has made my riding much safer now that I am OLD and my neck does not turn like it used to...
The mirror was smaller than I expected but it works great.
Just the right size, well engineered. Once you start using a bar end mirror, you will never want to be blind again. I do wish the whole thing was made out of aluminum.
Love it. Low profile and easy to use. Wish there was a way to lock it in place once you get it adjusted how you want it, I keep hitting it when getting on/off my bike and having to readjust
It is a good quality mirror. The size is actually large enough to be useful without being too big.
I broke the bar insert of my R50 while moving to Utah, and thought I’d try the smaller size mirror when I purchased a replacement unit. I really like the smaller size for me.
I purchased an R-35 just to give my neck a break during races. As many of you know the start is always hectic and folks are gunning for the same line. Instead of turning my head to check my six, I can quickly glance at the mirror to see if I'm good to move. It's also great about giving you a heads up when the fast gals and guys want to get around you. The mirror will give you time to move aside. It's also great for casual riding.
