And it's TiGr Lock for the Win! (graphic image from attempted theft)
 

This just came across my Facebook feed, a picture of a mangled .75" (the narrow one) TiGr that survived an apparently vicious attack last night in downtown Washington D.C.

I don't know much more than that, although there is a litany of questions on the pic waiting for replies, so maybe we'll learn more soon about how it was locked up.

The owner did say that when he came back, he was able to remove the lock cylinder and recover his bike in about a minute, so despite the massive twisting and deformation at that end, apparently once unlocked, it wasn't too hard to remove.

I'll update as more info comes in.

Pretty "wow," huh?

"Wow" is a good way to describe it.

LOL Somewhere in some dingy Washington basement, some frustrated bike thief is probably drinking himself stupid trying to forget that this thing laughed at his best efforts!

What is a TiGr Lock?

Interesting, but niche and somewhat pricey ... 200USD shipped to Germany.

ABUS Bordo and Defender RL for the same money seems like a better option.

However, I do applaud the company for breaking into the market.

I'd be interested to see how it would survive the LN2/hammer treatment which is commonly used here.

May I guess? : L is liquid, N2 is Nitrogen ..

Curious as to how the lock got that mangled and the frame wasn't damaged.

An uber blingy lock made of titanium.

Had to search for the product page myself.

There were at least a couple of other threads you commented on where I discussed why I thought the TiGr was better than the Bordo, but to recap, the TiGr is lighter, and provides a greater range of lockup options, most significantly in being able to capture both wheels and the frame. It's also more cut resistant and easier to handle. Weren't you the one who posted they'd chipped they paint when employing the Bordo?

In any case, which is better depends on one's needs, resources, and tolerance for compromise.

To the question of liquid nitrogen, titanium actually gets harder at liquid nitrogen temps:

when titanium changes from room temperature toliquid nitrogen temperature, tensile strength changes from 1000 to 1700 MPa. This means thatthe cutting force will increase, consuming more power and generating more heat. With regard toimpact strength, tensile elongation and reduction in area, the research literature is not consistent.However, most data showed that even at liquid nitrogen temperature Ti-6Al-4V sustains its tough-ness and ductility, without the apparent ductility to brittleness transition common for carbon steels. (http://www.et.byu.edu/~ered/ME482/Pa...rlandPaper.pdf)

The same is true for stainless steel, which the lock cylinder is made of. Stainless steel tanks are used in the transportation of liquid nitrogen for this reason.

I think you mis-read, because I didn't say the frame wasn't damaged; I don't know if it was or not. I just checked on FB for an update-- he was asked about that in particular-- but there has not been one. I'm curious, too, and will share what I learn. I also asked him to explain how the bike was locked, which may give some insight, too.

I would not characterize the TiGr as "uber-blingy." It has a matte finish and small, discreet, graphics; the lock is brushed finish. I think the vaunted Kryptonite New York Legend, with its garish yellow lock housing and large, bold, high-contrast graphics on the link wrap is truer to the meaning of "blingy" or flashy. Now, if by "uber blingy" you meant super cool, then yeah, no disagreement there! ;)

As an update, TiGr is reporting on their FB page that they've been in contact with the owner, they don't know if bolt cutters were used on it or how this was done, are getting the lock back for examination, and that the bike is fine. They are also directing anyone with further questions to contact them directly; maybe the lock owner wasn't thrilled to have dorky strangers like me asking probing questions on his FB page? :rolleyes:
