When you carry your water bottle behind your saddle, it reduces air resistance. It is the logical choice for triathlon and time-trials, where aerodynamics is the key. The angle and height of the clamp are adjustable. You can have one or two bottle cages mounted.

Rated 3 out of 5 by Anonymous It works but it's fiddly
Recently acquired and fitted, it works just fine - I fitted it to a FS MTB and the bike's rear guard keeps the bottle nice and clean, but if you haven't got a rear guard, make sure you have a bottle with a cap!
Why did I need this item? - the muppet that designed my bike's frame ensured a standard bottle fouls the rear shock!
Downsides....instructions a bit spa**e, I'd really recommend that you remove the saddle - it makes fitting the clamp soooo much easier. You also might want to fit any bottle cage **before** you connect the cage holder to the bit that clamps to the saddle. Captive nuts supplied for this but no bolts - and it's a fiddly job!
