Yeah, I am just a little uncertain of the safety - that's the main reason for my post! I don't want to eat dust whilst I'm riding because the bike comes apart! I also found another Multitrack, a steel 700, and I believe it's in my size, but he has said it's "fully refurbed" and is selling it for AUD$350 (USD$220)

As a new user I can't post links / pics until I have made ten or more posts! Let me know if there's a workaround.
