X2 on the Arundel Sideloaders. I have 2 of these on my bike. I had to switch to sideloading cages when I bought my 51cm Cervelo, because standard cages would not work due to the small frame. Yeah, they are carbon like someone else already mentioned...but I did manage to find mine for $40 a piece at trisports.com, so while that is way more than I really wanted to spend on bottle cages...in the end, they do look nice on my bike. There is a much cheaper aluminum sideloading cage offered from Elite...$12.99 at Performance Bike.
