The Why Cycles R+ V4 pushes the limit of what gravel bikes can be. The Why Cycles R+ V4 is made of 100% titanium, making it extremely lightweight and durable. This bike will literally last forever! The R+ was designed to be a long distance gravel machine. Designed and optimized around 700x40c tires, but can take up to 700x46. Or 27.5x2.1 if your feeling spry! Whether its buff singletrack, long paved roads, or backcountry gravel, the R+ is designed to handle it all. The R+ can go from being stiff and compliant on the road while somehow turning supple and damp on high speed washboard. The R+ comes setup for an optional internally routed 31.6 dropper post, to turn this beast into an unstoppable descending machine.

The Why Cycles R+ V4 Shimano GRX Gravel Bike comes with the new Shimano GRX Groupset. Shimano designed this group set to be 100% gravel with specific ergonomics, incredible gear range, durable, yet also sleek, quiet and stable. The Shimano GRX group set will add a certain crossover road bike feel bridging into the mountain bike realm of capability. Shimano GRX products are top of the line and designed specifically to cater to the needs of steep climbs, rugged descents, and far out dependability.

Whitens but not a pleasant taste.
Yes, it whitens teeth but is abrasive. Not sure how good it is for enamel, and it tastes terrible.

Great Toothpaste Alternative
I really like this teeth whitening powder. It is easy to use and leaves my mouth feeling clean and fresh. I also appreciate that it is made with nano hydroxyapatite and is designed for sensitive teeth. It has become a great addition to my oral care routine, and I am very happy with this product.

it's not bad
a coffee, tea, and alcohol drinker so i've gone thru a few of these. i knew i wouldn't see immediate results so i just tried to consistently brush my teeth with this. i can't say it made my teeth whiter but i think it brightened my teeth and helps to prevent it from staining? i didn't irritate my teeth or gums which is important, it helped my mouth to feel cleaner or was it bc of the flavors in it that makes it feel like that? also this little container is too expensive!

Great Product
Its a good product. It works gradually whitening teeth. I use this powder on top of the Boka Prebiotic toothpaste and I have to say I am pretty impressed how clean my teeth are, the whitening and no sensitivity issues.
