Locks that work

Here is a lock that works.

I wouldn't be surprised if Google look to buy these guys.

Hey steezy, do you know the guys over at the bike collective?

.

Does anyone have experience of installing a Sheffield stand on a concrete base? I'm soon to move into a ground floor flat that has an outbuilding. The roof on this thing is shot and needs to be replaced, but in the meantime I'm thinking about installing a couple of stands and securing with D-locks and heavy chains. Googling tells me that concrete anchors are the way to go, but my gut says that chipping out a hole and cementing them in would be better. Or should I just go with some other ground/wall anchors?

Ground / wall anchors are pretty good, the Hardie one is good.

The traditional or restricted type of key doesn't relate directly to the bump/anti-bump issue. That is down to the internal design of the cylinder and how the pins are machined, etc. Hence, you can have a simple, non-restricted key profile in a cylinder that is still anti-bump. Restricted profile keys are really there to make it harder to pick, and are a separate/independent defence against attack. Having both anti-bump and a restricted profile is good if you want to keep stuff safe.

Hi guys I wanted some advice and thought that this is the best place to ask for it. This September I will be commuting to uni (UCL) and leaving the bike there for most of the working day. The area is reasonably secure and better than leaving the bike on the street or outside a station, but not as good as indoor storage. What I wanted to ask is what sort of second lock I should get. I already have the fah mini u lock but can only really lock it with the Sheldon Brown method. I know some here don't agree with it but I feel that with another strong lock any attempts at stealing the bike based on real or perceived weaknesses of the method wil be minimised. I think I can leave the lock(s) there so weight isn't a real issue.

With that in mind I have a couple of broad questions: is it better to buy another u lock or a chain? I've heard it said that two different locks are recommended to force the thieves to carry two different tools but I don't fully understand why that would be the case: grinders will kill just about anything and bolt croppers a fair amount. If I did buy a chain, it would probably be the Almax series III immobiliser. Would a 0.7m chain be enough to lock the front wheel, frame, and stand? Chains are more expensive than another U lock so the reasoning behind it has to be clear to me.

Just having two U locks is more than most will have.

Almax III is not something you want to carry with you...

As I said I can leave the lock there. If there is no benefit to chains other than versatility in locking - not relevant as I will be using Sheffield stands - then I will go for another U lock

Thanks for the ( very speedy) reply!

Fag mini and krypo mini evo is the best combo.

I used to just leave my fag mini at uni lockup and use krypto on the go. So didn't need to carry fag around every day.

Depending on the stand, a choice of second lock can be tricky, especially if you want to be locking both wheels to frame and stand. I have a mini evo as a secondary but if the stand isn't the right length compared to my bike, it is impossible to get that lock around both frame and stand. Also a problem with the thicker stands. In those situations, I'm relying on the krypto cable to add a little extra protection to the front wheel.

I've mentioned this before on here and quite a few people seem to be happy just to lock front wheel to frame.

Guys have you see the new krypto mini? Thinner (same security level, from 13mm to 11mm, thanks to a stronger material), wider, and with an extension for the wheel.
Sorry for the italian video but I couldn't find any other source, at the end they show how the extension works:

I would prefer something larger to fit the front wheel, frame, and post as I would be using the Sheldon method which looks less secure and allows the wheel to be cut.

on guard bulldogs a cheap, good, light mini D. steels probably not as good but double locking.

You could leave your locks at uni and for uber security get an alarmed motorcycle disc lock. use it on the chainring. Even if you dont arm it, it still looks pretty scary secure.

I can't watch the video at the moment but I presume you're saying the Kryptonite "Evolution Mini-5" is being replaced by the Kryptonite "Messenger Mini"? Interesting.

The specs below highlight the differences:

Kryptonite Evolution Mini-5 (the one we know and love):

• 13mm hardened MAX-Performance steel shackle resists bolt cutters and leverage attacks
  
• Product dimensions: 3.25” x 5.5” (8.3cm x 14cm)
  
• Product weight: 2.15 lbs (0.98 kgs)
  

Kryptonite Messenger Mini (the new one):

• 11mm hardened MAX-Performance steel shackle provides lighter weight lock while maintaining the security level of Evolution Minis
  
• Increased shackle dimensions allows for a wider range of lock up scenarios
  
• Product dims: 3.75” x 6.5” (9.5cm x 16.5cm)
  
• Product weight: 1.83lbs (0.83 kgs)
  

For what it's worth, I think it's a nice addition to the lineup but I hope the Messenger Mini doesn't replace the Evo Mini 5. I don't want an overall longer, wider lock as my secondary - despite the weight reduction.

Don't worry, they sold (and produced) so many Evo Mini 5 that the stock will last for 20 years I guess :D

The new one isn´t the Messenger Mini but the Evolution LITE Mini-6: https://www.kryptonitelock.com/Pages/ProductInformation.aspx?PNumber=001447

Very useful thread, cheers

The new one isn´t the Messenger Mini but the Evolution LITE Mini-6

Ah, OK. So they've a few new ones coming out.

For my own benefit, here's a comparison of the three:

Kryptonite Evolution Mini-5 (the one we know and love):

• 13mm hardened MAX-Performance steel shackle resists bolt cutters and leverage attacks
  
• Product dimensions: 3.25” x 5.5” (8.3cm x 14cm)
  
• Product weight: 2.15 lbs (0.98 kgs)
  

Kryptonite Messenger Mini (new):

• 11mm hardened MAX-Performance steel shackle provides lighter weight lock while maintaining the security level of Evolution Minis
  
• Increased shackle dimensions allows for a wider range of lock up scenarios
  
• Product dimensions: 3.75” x 6.5” (9.5cm x 16.5cm)
  
• Product weight: 1.83lbs (0.83 kgs)
  

Kryptonite Evolution LITE Mini-6 (new):

• 11mm hardened New MAX-Performance steel shackle material allows reduction of shackle diameter while maintaining the performance standards of the Evolution Mini-5, Mini-7 & Mini-9
  
• Kryptonite's lightest weight U-lock option at 747 grams (1.65 lbs)-16% lighter than the Evolution Mini-5
  
• Product dimensions: 2.75" x 6" (7cm x 15.2cm)
  
• Product weight: 1.65 lbs (.74 kgs)
  

Anyone able to suggest what would be able to break this lock? Friends in Brixton Hill have lost their key and after 2 months(!) of hoping it would 'turn up' have appealed for help

Would anyone local with necessary gear/hacksaw/etc be willing to come help?
They haven't ridden in months.

They're right by brixton prison. I know, doesn't sound auspicious but it is true.

needless to say the lock and bikes are fairly cheap and nasty but it's that or not cycling - if anyone could suggest a tool they could hire cheaply that would do the trick that would also work.

thanks

Just about anything will get through those locks. An angle grinder will cut through in seconds, bolt cutters shouldn't have a problem, and if you can get the right angle/leverage, you could snap that black lock with a metal bar/scaffold pole. A hacksaw would probably work, but would take an eternity. The little red one will probably just require some colourful language.

Good luck (and don't worry about people hassling you, I've (legally) cut through locks in broad daylight on busy streets with sparks flying from an angle grinder and no one once questioned me).

Last time somebody bitch-locked me was with a lock like that (the bigger one). I used bolt cutters and it only took a few minutes. This was at the bike racks in front of Shepherds Bush railway station, mid afternoon on a busy day, and nobody batted an eyelid.

Excellent - thanks for your help.

You are most welcome. Let us know how you get on.
