This Arundel Tri Seatpost Clamp is no longer available although you may find similar or newer versions below:
This simple device clamps to the seat post instead of the seat rails, and it fits virtually all seat post shapes. No one else makes one like it.
Triathletes popularized this behind the seat method of carrying water due to their need to hydrate like crazy. It’s common to use two reserve bottles behind to dump into the front bar-mounted bottle, the one with the giant straw attached.
The key to the Arundel Tri Clamp is the use of a “V-block” design with convex inside surfaces. This helps it fit a variety of seat posts. Round or aero shaped. By tightening the 6mm mounting screw, the Tri Clamp will stay securely fastened, while allowing for some shock absorption.
Athletes benefit in several ways: The Arundel Tri Clamp fits well and remains secure, the bottles are easy to reach and it doesn’t cost an arm and a leg.
Water bottles and cages are essential items for your bike, fluid replenishment is essential for long term activities and fitting a water bottle and cage to your bike is the perfect way of keeping you hydrated. Studies show that loss of fluid equal to 2% of your body mass is sufficient to cause a significant decrease in performance. Bottle cages have also received the lightweight treatment with materials such as carbon, titanium and alloy often used. These cages will accept water bottles from 500ml up to 1,000ml, making it possible to carry 2,000ml of fluid on your bike. It's also worth using an Energy drink whilst riding as these will help replace minerals lost through sweating.
