    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 fromLightweight speed tool Bike lock are trade-off. You can have light, long, strong and cheap: pick two. This one is light and cheap. This lock has a smooth locking system, is long enough for one bike in pretty much any configuration - struggles a bit to get around two - and is light. Of course, it's probably easier to break than a heavier, shorter lock would be. See first paragraph. Downside - and this is common with bike locks - the bike attachment slips. The lock slips down the attachment while riding. So, I put on some duct tape (ahhh duct tape) to tighten the clamp and fixed it.

    by fromNot 14mm This is not a 14mm shackle. It is 14mm including the rubber coating. Since it is hexagonal I can measure 2 ways: min=10mm, max=12mm. I personally wouldn't take this on a multi-city bike tour where loosing the bike would ruin the trip even though weight (or lack thereof) is crucial on such a trip. I will stick to my 18mm shackle 2.5kg Magnum lock. You just can't get by with less weight (except by shortening the shackle, but that would still be about 2kg). The question really comes down to whether it can be cut with bolt cutters, and if not, how long does it take to saw off without power tools. My choice would be 13mm mini ulock for around town, or 18mm for leaving the bike for an extended period.
