Thanks for the tip! I'd never heard of cyclocross bikes before, but once I started reading up they sounded perfect for my use. Fast and light but just a bit more robust.

Only problem is the market for cyclocross bikes is small here, so they're all for enthusiasts, and just out of my price range...

In the meantime - woo hoo! I've arranged to borrow a real road bike that should fit me reasonably well! I'm REALLY pleased with this, because it gives me a chance to try out a completely different type of bike in peace and quiet for several long rides.

I'm thrilled
