The Puncture-proof mountain bike tires

Are you looking for mountain bike tires that don't need air, here it comes. Examine the pictures below because it is probably what you are waiting for..

Puncture-proof tires that incorporate a flexible internal matrix instead of air are nothing new, in and of themselves. In the past several years, we’ve seen prototypes from the likes of Michelin, Amerityre, Goodyear and Bridgestone. Colorado-based Britek Tire and Rubber has also been developing something similar, known as the Energy Return Wheel.

According to Britek founder Brian Russell, the stretching of the internal rubber layer allows elastic potential energy to be stored within the wheel. As that layer is compressed by bumps transmitted from the road, the stored energy is supposedly returned (hence the name) and converted into forward momentum. It is also said to press the tread onto the road instead of allowing it to bounce off, as is sometimes the case with pneumatic tires.

The new mountain bike version of the wheels incorporate lightweight 29-inch carbon fiber rims, and (like some of the automotive prototypes) are open on the sides. Russell is wisely considering adding thin sidewalls, to keep mud and trail debris from accumulating within them.

The Bodyfloat bike suspension seatpost

If you are looking for bike parts, or want to try a new one like Bodyfloat, it is definitely a new experience of riding a bike,

In case you haven’t figured it out by looking at the picture, BodyFloat is a replacement bike seat post that doubles as a suspension system. The patent-pending design utilizes dual spring parallelogram science something or other (kind of looks like the alien legs from “The Arrival”) to basically remove you (and your ass) from the potentially painful equation of potholes, long rides and vibrations. It’s available in a bunch of different options (including carbon fiber!) through Kickstarter and was designed by the talented people at Cirrus Cycles in Bellingham, Washington. It’s like moon shoes for your butt… when you’re riding a bicycle. It is about $200 in price.
