I'm afraid of my Specialized Dolce. She's a beautiful bike and satisfies my need for speed, but she's so light and twitchy that I never feel fully comfortable on her. It's not because of the few falls I've had from her: I've suffered more, and bloodier, crashes on the Ariel. Nor is it the function of being clipped in: my clipped falls on Circe were at a near stop while my clipped falls on Lily were at speed (see "bloodier" above). I don't feel like Circe is under my complete control and it makes me hesitant to ride her.
A local friend has a Dolce, which is two years older than mine, and she feels the same way about her bike. She's not the collector like I am and this is her only bike. At least I have a choice when I want to hit the road for a bit of two-wheeled freedom.
Anybody else? Do you have a bike that gets neglected because it gives you the heebie jeebies?
