The frame is carbon, the steerer tube has split at the top, roughly where the upper part of the stem clamps around it, and after a few miles this causes the headset to slacken off. Also there is a fair bit of corrosion around the crown area. As well as that the springs have gone in the calipers and I cant replace them as the bolt attaching them to the forks has seized
See what you're saying about the cost though. I paid about £1500 for it 10 years ago. It's done 40k and saves me about £800 a year in petrol. Think I've had me monies worth out of it.
