Lovely bike! I do think those Trek Skyes are exceptionally pretty.

I'm a new rider too, starting out at 44 after some very limited riding in my late 20s. My suggestions are to book a couple of sessions with an instructor if you are at all nervous, mine helped me immeasurably. Also, go and make friends with your LBS. If they don't play nicely then check out another LBS. I ended up doing this and it's so worth the extra 15minutes drive. I've just bought my second bike from there and they have already agreed to swap out the saddle for me, and to swap the new saddle too if I have problems with it.

I still find that I'm nervous sometimes, even after a stunning 5 months riding I think a certain amount of nerves is normal, the longer I leave it between rides the more I worry. But it's always fine once I've actually got on the bike and just got going. Have fun on your gorgeous bike and please do post on the Newbie's weekly achievements thread if you feel like sharing your rides with us!
