Abus Granit X-Plus

• 13mm shackle
• Handsaw 124 sec
• Grinder 230 sec

Kryptonite New York

• 18mm shackle
• Handsaw258 sec
• Grinder 118 sec

I have the NY lock std 16mm, it is a monster 4lbs ... so heavy. Thinking about getting a Abus Granit X-Plus 54 Mini which is only 1.6lbs

My question

• why is the Kyrtonite stronger against handsaw, but weaker to a grinder?
• Conversely, why is the Abus stronger against a grinder, but weaker to a handsaw?

doesn't make sense to me.

University PHD in materials science & Mechanical engineering, department question..


some may ride bikes..


look for a website , that gets manufacturers to give them revue samples ,
which they submit to destructive testing using power tools and so forth ..

Get both, and it will take them 5 minutes to steal your bike. Plus you’ll be out a couple hundred bucks for the locks. And hope they don’t bring bolt cutters and a pry bar.

someone else mentioned that it seems data for Abus locks got inputted wrong on the chart, their values were swapped.

charts says 230s for grinder and 124s for handsaw, but probably meant 124s on grinder. Which is more in line with the Kryptonite grinder time of 118s


I have both now. But going to use the smaller/lighter Abus for my short stops to the grocery store etc. Every single lock can be defeated by grinder in less than a minute or two so why bother carrying a heavier lock. I'll use both locks probably only at work or something to make the next bike near by easier target lol

Yeah, my critical thinking cap has me there with you - can't imagine there's many materials more easily cut through with a hand saw than a motorized grinder.

I have the Abus 540 as well - nice lock, definitely lighter than my wife's New York Standard. Just don't drop it because that shell over the lock goes apart easy.

I've used both, and one of the biggest differences in my experience is the lock cylinder itself. My Kryptonite would stick all the time, especially after rain. The Abus is still smooth as butter after years of use. Both were regularly oiled with a lock specific lubricant.

MEversbergII

Which did you use? I still need to pick some up. Did y our Kryptonite have the slide-over for the lock, or just an open hole?

I have a Granit Bordo in a small town with a few useless tweakers ..

who would not buy a grinder instead of more crank.

I removed the plastic shell from my Abus, better that way

Hisamatsu

Isn't the housing used to protect against the elements? Keyhole cover springs close and plastic housing protects against corrosion?

Archwhorides 

The Abus lock components all appear to be galvanized, I've been using the lock without the plastic casing or lubrication for years, no sign of corrosion anywhere, the locking cylinder is working beautifully, and I prefer the leaner industrial look.

fietsbob

Bare metal is just going to be hard on your bike's paint, that I believe is the purpose of the plastic covering..

But your call ..

Archwhorides 

Abus does not encapsulate the U-part of the lock, which typically has more contact with the cycle frame while locked; if they did I would let it be. The locking case has less contact, at least the way I secure my steed.

fietsbob

I got the Bordo instead...

acidfast7

Bordo user here as well.

Withstood bike as car replacement in Frankfurt for 3 years.

Can't recommend enough as it folds up and mounts cleanly in a water bottle holder position.

dim

where I live, guys cut your frame and carry the bike away, then sell all the parts ....

get good locks but most importanly, get proper bike insurance ....

acidfast7

Yup.

And Portsmouth is much worse than Cambridge.

Also, never replace and store your bike from where it was stolen. Most thieves will come back to the same shed/conservatory/garage three months later and steal it again ... and insurance will be hesitant to pay a second time.

noglider 

Ooh, good tip. I didn't know this.

acidfast7

Yeah. It's quite tough to change the infrastructure here (similar to manhattan with respect to being completely developed urban space I would guess) and most people just reuse the shed/garage/garden without any security changes (which are mostly impossible anyway with respect to money and/or access) and it gets nicked a few months later again. Usually, a newer and nicer bike the second time. Thieves aren't daft most of time.

Abus Granit 54 and Kryptonite NYFU. The Kryptonite had the slide-over, but if memory serves me correctly at some point it broke.

Hisamatsu

I have had 3 kryptonites. The slide cover is just plastic which can easily break if dropped on. Had one new lock that came with it broken. The Abus has cover that automatically springs close which doesn't appear to be plastic
