and the new Onguard Brute seems a bargain at £24 for a gold rated 16mm+ lock Magnum ONGUARD Brute STD Bicycle Security Bike U-Lock LK8001: Amazon.co.uk: Sports & Outdoors
Manufacturer's brochure here:- http://onguardlock.com/wp-content/uploads/2013_OnGuardCatalog_NEW_web.pdf
If you haven't already read it, there's a good article about bike locks here http://www.ctc.org.uk/sites/default/files/file_member/200803042.pdf
Down to £18 now! Damn, I paid £30 the other week.
Nice! But I'm afraid that the standard brute is too big for me maybe? I'm currently happy with a normal mini but it's just 13mm and amazon doesn't have any offer on the brute mini.

Too short Neil? The Masterlock Streetforce 10 would have been perfect, but it's discontinued. I'll have to amend the list.

i'm currently looking for a new lock and i like the idea of locks who don't scratch frames like my last abus chain (which were also weighing tons) like the knog strongman or the abus ugrip plus 501. i read the tests about the knog but couldn't find any info if the abus is better than the knog. any advice?

The Torc ground anchor is our product. FYI We asked the BikeRadar/C+ guys to replace the photo on that review as there's no way you should fit any kind of ground anchor to block paving - the blocks just lift up - Doh!

http://www.reliancemarine.com/Product/17745/Stainless-Steel-Eye-Bolt-16mm/View.aspx?gclid=CMK-wtm72bcCFdShtAodJx8AQQBeware that this is likely to be too small to use with any decent chain as it quotes "Eye i/d: 34mm".
Beware also that any home-grown solution that doesn't have a formal approval will probably not satisfy the requirements of your insurance.
Perhaps there should be another thread: "Ground anchors that work" ?

Both locks received a Bicycle Gold rating from Sold Secure. I would choose the Abus because there is more space inside the shackle.

I'd favour the Abus Granite 54 x-plus over the Knog at that price point - £56
Yep, it looks like a very good all rounder. Good enough to make it into the "locks that work" list, but almost conspicuously so at only 13mm (square). The only other positive I can think of for the Knog Strongman, is that it's silicone skin would be annoying to thieves. It would gum up a cutting blade. It would take longer to cut away the skin with hand tools than it would to cut through the shackle with an angle grinder! So it gives it a sort of unexpected advantage.

£24 with delivery. It seems too cheap! Isn't there some sort of quality issues with it? For OnGuard, I've heard of keys made of soft metal that breaks and really bad weather-proofing. Although I don't know if either of those applies to that specific lock.like the knog strongman or the abus ugrip plus 501. i read the tests about the knog but couldn't find any info if the abus is better than the knog. any advice?
The Abus is meant to be 13mm square, so should be thicker, heavier and more secure than the Strongman which is 13mm round.

The Abus Granit X 54's 13mm square shackle is approximately 15mm in diameter, corner to corner.
Do you want to know the exact calculations for the cross sectional area? Finding area of a circle using... Area=(Pi)r²
13mm round = 132.732mm²
13mm square = 169mm² (27.3% greater than 13mm round)Finding the diameter for a given cross sectional area, X, using... Diameter=2*(square root(X/Pi))
169mm² = 14.669mm round
So to sum up and assuming all else is equal...
- A 13mm square shackle is 27% 'tougher' than a 13mm round shackle.
- A 13mm square shackle would be equivalent to a 14.7mm round shackle.
- A 13mm square shackle is 27% 'tougher' than a 13mm round shackle.

Ground anchors that work... ?
Closely followed by one entitled "How good is your concrete slab"?
Good point. Most people don't realise that the concrete is the weak point, at least it should be compared with any decent anchor. Brick is weaker still and block more so, as a rule. Hence, it is important to have at least a 3-bolt fixing on any good anchor, and spread out. The worse the substrate, the larger the fixing area required to get a good anchoring effect. You can compensate for virtually any grade of substrate, but anything fixing to a small area or using just one or two bolts can't be any good IMHO.

Onguard have changed the lock and key design in their new 8000 series range. It is now a pinned lock with the coding cuts on the inside edges of a 'z' profile key, so the key ought to be stronger than the old design, and there are no discs to get misaligned and it shouldn't be possible to turn the key if it is not fully inserted.
The previous model 5000 series Onguard locks used a disc key, as do Kryptonite and Abus. As the disc lock keys are double sided, deep coding cuts make the key thinner, creating a weak point where it could snap if the mechanism gets stiff and rusty, or the key hasn't fully inserted and sticks when turned.
I've read a few reviews where the key has snapped in Kryptonite locks too: My Kryptonite NY 3000 started getting stiff, presumably from rust, after just one week of ownership, although a drop of mineral oil and plenty of WD40 squirted where the hasp goes seems to have cured it.
Abus keys are apparently thicker, so less likely to break, and maybe they use more rust resistant materials in their lock - I would certainly consider Abus a superior brand to kryptonite or Onguard.

The quality is inferior to my Krypto mini D and I'd feel less happy leaving it out in the rain.
But, at a third of the price of a fag mini I decided to go for it. I didn't want an everyday lock, just something for longer term storage and use in higher crime areas. On that basis, it seems spot on.

I love a good anorak me. :-)
Glad to know that approximately 15mm is just not on, when 14.7mm is so much better.
That has given me a good laugh. :-) But well done anyway for illustrating it so precisely.
I think that was the first time I was able to use a few little calculations to make someone laugh. But if you are pleased, then I am pleased :).
