Review on 🚴 Tannus Armour Tire Inserts: Puncture-Proof Bike Tube Protector for Thorns & Pinching by Will Randles

Okay, those were the only 'whistle' I was able to get in early July 2020. The installation went well - I followed the instructions exactly. This product has HUGE design flaws: 1. It is not possible to maintain the correct position/orientation of the foam inside the tire during installation. When the tube is inflated, it can change the position of the foam. This causes the foam to unbalance the wheel. As I spun my wheel, this imbalance caused the wheel to wobble back and forth. In fact, it was probably misplaced foam that was being forced into a sub-optimal position when the tube was inflated.2. When riding, the foam between the tire and tube compresses and gives the feeling of a flat tyre. It is extremely difficult to drive comfortably with flat tires. From time to time it felt like I was pedaling with the brakes on. Before installing them, I drove at an average speed of 14 miles per hour. With the product installed, I couldn't get the bike over 11 mph. After tossing them in the trash and installing the tubes properly, I hit 16mph. The only good thing about this product is that the added weight and compression of the foam seemed to strengthen my legs. It was like driving with the brakes on. Do not buy this product. I would ONLY recommend this product to those I have raced with to give me that extra edge.
