As with our lists from 2012 and 2013, these aren't necessarily things that we think are destined to be big sellers. In fact, it's entirely possible that this might be the last you hear of many of them. We like 'em, though, because they're examples of what happens when people dare to try something different ... and that sort of spirit is the reason why we're not still all riding penny farthings.
Schwalbe Procore tire system
Setting a mountain bike's tire pressure is a bit of a balancing act ... too hard, and the tires won't provide decent traction – too soft, and they're likely to get pinch flats, plus they might not stay seated on the rim. As a result, cyclists usually compromise and keep them at a "somewhere-in-between" air pressure.
The Procore system, however, allows for the best of both extremes. A high-pressure tube within the tire helps protect against flats and keeps everything in place, while an air space between that tube and the inside wall of the tire can be kept at a very low pressure, allowing for excellent traction.
Price: Approx. US$230/pair.
