I recently bought one without really knowing what I was really getting (implulse buy). I guess it's part of the learning curve. It's a mavic tubular with helicomatic hub and a new 5 speed cassette. I'm considering it an tubular experiment on a back up bike. It's not going to explode - the goal is to get a year or 2 out of it - it's like new...
When I took it to the bike shop, the tech said "you know, this is a helicomatic". No a good sign. I was told that they do have a tendency to crap out, but another tech indicated that with the new cassette and very little use - it's ok...we'll see. It's probably not the best of decisions, but also not the worst...
