Formally called the BC-1, this cage has been around for decades. Composed of medium weight alloy, these cages offer increased strength over light weight cages and excellent bottle grip.
If you want a good strong cage that does not cost as much as your first bike and just want a cage that holds your bottle without losing it, look no further. These things have been around forever. They just work. You cant go wrong. They have zero zoot appeal, but you wont have to double back for that bottle you just lost. So easy a cave man could use it.
