Bikes are my hobby -- I like building them as much as I do riding them -- nothing's ever "done". :-)
This is why I like C&V (classic and vintage) bikes. There's always something to do, and there are so many ways to take a project. I'm riding my two steel bikes more than I am my modern aluminum bikes lately. I haven't ridden my Roam or my MTB in weeks -- it's all my 1997 Trek and 1970 Peugeot.
