Fizik has a long history with successfully using spinal flexibility as a factor in saddle design with its semi-custom line of saddles shaped to suit riders' biomechanics, rather than asking riders to make a saddle shape work for them. The Bull, Chameleon, and Snake distinctions are well-known and respected, so it only makes sense that as its next project, Fizik would address the part of kit that comes in contact with the saddle the most. The resulting Link R3 bib shorts includes its own Bull, Chameleon, and Snake inserts shaped to integrate with their corresponding saddles.
