    The REI Member Dividend

    The REI dividend is a unique benefit of membership in the REI co-op. It's comprised of your member refund—typically 10% back on eligible purchases—and/or your REI Visa® card rebates.

    Each March, active REI members and REI Visa cardholders who earned a rebate receive a refund in the form of an annual dividend notice.

    Only active members receive annual dividend notices. To maintain your active status as an REI member, you need to make net merchandise or shipping purchases of at least $10 per year, unless you joined that year. Member numbers are issued in one name and only that person receives the member refund. Your number can be used by others in your family, but it cannot be transferred to someone else.

    by fromok-needs frequent re-adjusting I wanted this so that i could go on longer rides. It installs easy but during a ride, especially if there are bottles in it, when you hit a bump it moves. Since I am on the shorter side and the seat is lower, that means it rubs the tires. If there is enough room between the unit and your tires, I'm sure it would be fine.

    by fromSimple and strong Great for long rides/triathlons. It maintains a good grip on the bottles. I've had no problems with bottles coming out, even on the notoriously bumpy Vineman course. Granted, it would be awkward to reach behind the seat for a drink. Instead, I use this to restock the 2 other bottles I have within easy reach under my torso. An alternative would be a between-the-aero-bars or reservoir type system with a straw, but I prefer the simplicity and flexibility of this approach.

    by fromGOOD MOUNT good to go. I have had one thin walled plastic water bottle that got a leak in the bottom of the bottle after 200 mi. but it works great if you have a ok bottle.

    by fromLove REI's return policy I used this on four rides. Only one did it do what is was supposed to. Two out of four I had water bottles bounce out (more than once), mind you I was on a paved trail/road on a tri bike. The last time I used it was during an event and the roads were rough. The entire piece came off while I was at speed. The good news, the cages and mounting system held together well enough for me to return for a full refund.

    by fromGreat saddle mount cage I've tried several saddle mounts and this one is the best I've found for the price. First of all, the mounting hardware and process was very straightforward and simple. Very few parts and a solid fit. It mounted easily and appears will stay tightly fastened. I use it for long-distance rides and triathlons, and it's easy to remove and replace the bottles while riding. The bottles sit securely in the cages and I haven't had one fly out. It's a bit heavy, but I would not spend $100, $200, or more for a lighter option. I can also still easily mount my spare/tool bag. I'd definitely recommend it.
