any thoughts on Marin Rocksrings?
What thoughts are you wanting to know? I ride an 04, for my type of riding (steep climbs with just as steep desents, and enjoy a 4 foot drop every now and then) I love it. It really likes to climb, which is just a side benefit for me, since I endure the climbs so I can bomb the down hills. For being such a good climber, it is super plush (which usually don't go together). I use a cane creek Cloud 9, with no platform damping and really like it.
The bike won't win a beauty contest, but will rock your ride. Also the prices are great, especially how awesome the bike performs. I payed less then $1000 shipped from http://bikeconnection.net/itemlist.cfm?category=52
