Singlespeed?Why singlespeed.org? What is a single speed? Is this a single's club or something? Good questions.
Single speed refers to a type of mountain bike which has recently gained in popularity because of its simplicity and retro style. Only one gear - so no shifting. Often they are simplified even more by using a rigid (non-suspension) fork. As bikes become more complex, more and more riders are desiring a less complex system, which a singlespeed accomplishes. And there is almost a laid back counter culture which goes with singlespeeds, which is very different that the high dollar, commercial scene that has taken over mountain biking.
So, no, this isn't a single's club.
And, yes, I do have a single speed. I have a Santa Cruz Chameleon and ride it quite often.
