"This is the chain to go with if you've ever had a theft attempt on your bike, or are smart enough to prevent it. It's 11/12 on their security scale and offers the highest level of reimbursement they will pay: $3500 for your bike if the lock is cut. This chain comes in at about 6 pounds, which is the highest reasonable weight I'll carry on my bike. Ok, so the noose design as you'd imagine turns this 2.25' (not 2.5' like the title says, not sure why they advertise that) and essentially gives you as much chain length from your bike to bike rack as a 4 foot chain would. A regular 4' chain would have to wrap in a circle and you'd connect both ends, so your bike could only really be 2' away from the rack. This chain ALSO gives you 2' between you and the rack with you looping or "noosing" it around the rack, thread it through ur back tire (always) and lock the chain to your seat tube or down tube."
"I originally bought the largest chain because I park my bike in downtown Manhattan, but I found that one to be *far* too large and weighty for commuting."
"This lock is excellent. It is a little on the heavy side, but it's worth it for a little extra peace of mind."

"I have the chain looped around the frame of the bike and the ends locked to my Jeep's frame every night."
"We wanted to take expensive folding bikes around the Yucatan to explore, and not worry about our investments disappearing during the trip. We tended to park our bikes next to motorcycles or in front of shopping malls/bigger stores where there were valet guys and greeters and such. We found the locals actually just as concerned as we were, asking if we had a good lock when we started parking them, and generally excited about seeing these unique bikes."
"I weave the chain through the center stand and frame of my bike and lock both ends to the rear sprocket."
"Great lock, two keys provided (one with a built in LED light), and a dust cover for the lock itself."
"Great lock and chain."
"Unfortunately there aren't many fixed concrete poles to securely attach my motorcycle to (only regular parking lots) so I never really had the exciting opportunity like other reviewers to beat down hoodlums with the chain."
"I chained it around a light pole.when I was walking back to get my bike , I saw this pice of sh#t of human being right next to my bike cutting the lock using a hand saw."

"This is an awesome bike lock and a great deal when you compare features and benefits with other bike locks on the market!"
"After having our bike room broke in to I wanted something heavy duty and this fits the criteria."
"Tremendous bike lock compared to my previous one (Masterlock U-Lock)."
"I've tried to mount other locks and they always end up interfering with one of my other accessories (cup holders, usually)."
"I found the mounting flexible enough to mount in a limited section of my upright tubing and still fit without conflicting with the pedal crank. I also like the large enough locking dimensions so easy to lock without the cable to a post or railing."
"Keep in mind the U-lock is somewhat short so when you lock up your bike frame, your bike must be placed very close to the bar in which you're locking it up to."
"I would have liked this lock and cable to put up a bit more resistance."
