This is the best track power meter out there. No question about it. With fully independent left/right power readings, you can dial in your pedal stroke and make the most of every training session. Our dual-sided 2INpower measures power individually in each leg to provide precise data about balance and power output in order to demonstrate where improvements can be made to pedaling performance, so you can harness the information and push yourself to the podium.

As the name suggests, 2INpower evolved from ROTOR's INpower, with the power meter tucked neatly inside the crank axle that measures power in the left leg. However, on the 2INpower, two additional sets of strain gauges have been placed in the right crank arm, which offer precise measurements of power exclusively in the right leg, balancing out your drive and non-drive side with accurate readings, so you can hone your power in both legs. The eight strain gauges reduce the chance of adverse effects from external conditions like rapid changes in temperature or barometric pressure.  We opt to house the strain gauges tucked neatly in the crank axle, while electronics stay spindle-bound for protection against the elements. 

2INpower features both Bluetooth Smart, and ANT+ functionality, as well as a built-in rechargeable battery for easy charging between rides. Please note that chainrings are sold separately.

Best sunscreen
Size: 5 Ounce (Pack of 1)
My family and I use only Blue Lizard sunscreen. We think it's coverage and sun protection works best.

Waterproof
Size: 5 Ounce (Pack of 1)
This product is great for kids in the pool or ocean. It is very waterproof and you can even see the water beading on top of the sunscreen. It doesn't go on super clear, which can be an advantage for determining coverage. One other unique feature is the bottle itself changes color to indicate it is currently exposed to UV light although that is basically anytime you walk outside in daytime.

Good sun protection but leaves white streaks after sweating
Size: 5 Ounce (Pack of 1)
I really wanted to like this sunscreen after seeing it make a lot of lists for best sunscreen for runners. But for whatever reason, about 15-20 minutes into my runs and I've started really sweating, I see white streaks in my elbow crease. I've started developing weird tan lines in my elbow crease if I don't consciously try to re-rub and re-spread the sunscreen in my elbows periodically during my runs. If I only use the sunscreen for lower impact activities, I don't get the white streaks. It's as if from the sweat it pools the minerals from the sunscreen into my elbow crease. But yet I don't have that problem with the sweat mix with my sunscreen on other parts of my body. I've also switched to Australian Gold Botanical Mineral sunscreen which ironically isn't meant for sports, but I don't have the elbow crease white streaks issue with that sunscreen. I will say, this Blue Lizard sunscreen does rub and spread easily and doesn't leave a white cast after rubbing it into my skin. Although it does feel mildly greasy after I'm done applying it everywhere. I've switch to Australian Gold Botanical Mineral sunscreen which doesn't feel greasy but it does leave a slight white cast on my tan skin, but I'll rather have that than deal with frequently needing to re-rub/re-spread the sunscreen in my elbow creases when white streaks form.
