Blackburn Sing Sing – A Different Approach To The U-Lock

with 4 comments


I’ve been needing a new u-lock. My cheap-o lock u-lock from college was showing some serious wear and tear, and I was down to just one key – which happened to be the old, easy to pick, barrel kind. As a temp fix, I picked up a simple cable lock. It did the job, but as we all know, could easily be compromised by some cable cutters. It was basically used to keep the honest folks, honest.

Of course, there are lots of great products on the market from companies like Kryptonite, OnGuard, etc. I was going to pick one up for this year, until I saw the Blackburn locks featured in Bicycling magazine. To me, Blackburn is known for their air pumps, cyclometers, tools and trainers – I never expected a bike lock in their lineup. I was intrigued by their hexagonal shackle concept – so I picked up a Sing Sing from Amazon.

Here are the specs from their site:
• Hexagonal 14mm alloy steel shackle with anti-scratch liner
• Maximum resistance to cutting and leverage attacks
• 12 tons of cut-strength
• Bump-proof, pick-proof dual-bolt lock mechanism
• Three laser-cut keys with key replacement program
• Mounting bracket included
• $2500 Theft replacement guarantee
• 159mm x 76mm
• Security Rating: 10

The hexagonal shape of the shackle is a pretty cool concept. It prevents the it from spinning, effectively doubling its resistance to cutting and leverage attacks. The pick-proof dual mechanism engages the shackle at both ends, also adding to the security.

I got a good, first impression of the Sing Sing. It’s feel heavy and substantial, with a pretty good build quality. My only complaint would be is that the plastic cladding around the base doesn’t feel as substantial as some of the competitors out there. However, the cladding does do a good job at keeping my bike free from scratches.

It comes with a bike attachment, but  Sing Sing is just the right size to just toss in my bag. The trade off is, that it’s heavier than my cable lock – a compromise I have to make to have more security. The inside space of the lock has just enough room to lock my frame and one wheel (removed) – depending on what I’m locking it to. The Blackburn locks do come larger sizes like the San Quentin, Leavenworth and Folsom (yes, all prison names – those clever marketing guys) for those who need the space.

Overall, I’m pretty pleased with the Blackburn Sing Sing. Is it actually better than any other u-lock out there? That’s a question I hope I never have to answer. The $2,500 Theft Replacement Guarantee, does add to my confidence. The suggested retail is $69. You can find it a lot less if you shop around like I did.

  1. Amazon says the shipping weight on this is only 2 pounds. Not bad.

    Question for you: how would you rate your confidence in it’s use as a weapon?

  2. This is an old post, but seeing as its the one of the few reviews out there…What was your experience with the lock after extended use? Thanks.

    • I’m still using it, and still pretty happy. It’s gotten a bit banged up and the lock is occasionally finicky, but it’s still rock solid protection.
