That said, what did you mean by "reports of it locking onto your bike"
Apparently it can be hard at times or even impossible to unlock. Which could be irritating to say the least. Or possible force you to leave your bike for longer than you planned, possibly overnight in a dodgy area, making it a sitting duck for leisurely thieves. Not what you want from a lock. :smile:

So still looking if anyone has any suggestions - cheap, medium size, light. Moderate security OK.

Many locks attract similar complaints. Sometimes because the owner has used a cheap spray lubricant in it that leaves a sticky residue. Does that one have more than usual?

I don't know mjr, perhaps I just took fright because it seemed such a serious problem.

On the subject of lock lubing, can you say more?

I rarely lube locks and when I do I use gt85 or wd40, the latter in particular seems to work fine on my sometimes problematical door locks. I know some folk recommend graphite of some sort but that sounds too complicated. Thanks for your encouraging words, I may reconsider the kryptonite.

You need not worry about the locks seizing (Among other quality control issues) if you're buying a lock from a reputable source and from an acceptable price point.

The only locks you should be hesitant of, are the unnamed, unknown, cheap ones. that have no one to back their standards.

The one you posted there is fine, it's cheap but not cheap enough to be of concern and onguard are reputable.
Though, that clocks in at 930 grams. I do think it's pretty heavy compared to the prior options.

As of your cleaning concerns, WD40 is acceptable, it's a solvent so it eats and dissolves Rust and Grime that'd otherwise cause your lock to seize, actual lubricants (such as Lithium grease sprays) Will Attract dirt and worsen the problem as metal-on-metal wear & grime occurs. -- it'd be attracted by the lubricant, not the solvent.
IMO Locks don't need lubricating, they just need degreasing, WD40 is more than acceptable for that.

Anyway, as you're trying to keep your lock criteria small, lightweight and secondary, I still maintain You're going to have trouble finding those criteria with D locks, as almost 99% of the time D-Locks are Primary locks, so they're big & heavy.

I use an OnGuard https://m.ebay.com/itm/OnGuard-Bull...lok-Series2-/291513341067?txnId=1523781178019 and it was the best I found for the price. You can order it with or without the cable, which I loop around my wheel and to the fence at work. The locking mechanism is very nice and hefty, doesn't move at all, and the keys seem well made. The mounting thing that came with it was useless as with my bike no matter where I tried to configure it on the frame it wouldn't work, but I just toss it in the pannier.

Also I have always used Wd40 on locks, even the old shed lock that gets all weather, and never had problems. It is used for freeing stuck bolts/hinges/mechs so since it gets rid of rust and grime buildup we use it on everything at home! If you had a lock that wouldn't unlock I would try that.

Thanks draconis
Yes i have an onguard lock. I rate them.

The one I bought for this application in the end was also an onguard, the Neon listed above (mountain warehouse thing is going back). The saving of half a kilo over my primary lock is nice. It's a bit long for what I need it for though so not absolutely ideal.

So yes i recommend their locks.

Agree with you about WD40.

If you don't understand that use of a cable (and I'm not arguing) your mind would have been fried by the bike I saw parked/"locked" in Putney a while ago. Cable looped through both wheels and the passable D lock used to link the loops on both ends of the cable. Weakest link or what?
Someone at work does this all the time on the stands outside and it gives me a feeling of dread every time I see it. The bike is a Temple that's always kept immaculate so not a BSO by any stretch and seems to be looked after so why would they risk it like that? There are regularly dodgy characters on this road stealing bikes or snatching phones.

Have you mentioned it to them? It is possible that the problem hasn't occurred to them. I assume that the Putney person was oblivious to the fatal flaw. I can only hope that thieves were as well, unable to process what their eyes were telling them.

I've never seen who rides it as they're in another building and arrive and leave after I do. I could leave a note but i always worry that'll actually attract attention to the bike and the lock which wouldn't be ideal.

I wouldn't use a cable lock full stop. The only D-locks I would use are Abus. I am prepared to carry a heavier lock if I feel it necessary and so often carry an Abus Granit X-Plus either the 230mm or 300mm shackles, depending where I am going. I also have these lesser specced Abus D-Locks but still gold rated.

I am looking at getting one of these for when touring https://www.cyclesurgery.com/p/abus-bordo-6000-folding-lock-P5240003.html?colour=180

If you really value your bike and don't want the hassle and grief of losing it then buy a good lock.

Yes, but this was talking about using a lighter lock. There's no need to take the last word in heavy weight locks for a cafe stop, which is where cable locks come in.

Also becareful what you wish for. :whistle:

Ehhh? Lighter lock inevitably less secure. Cable locks can be snipped in all of 1/4 of a second.

Why have you linked to the lock on Youtube that you did?

Do what every you want. It's your bike any way. As your lock will likely be weaker than mine thieves are more likely to take your bike than mine.

Depends, if you've gotten a good quality thick cabled cable lock then the material used wouldn't yield so easily.
And because you were thinking of buying a folding lock for touring, IMO you should reconsider.

I wish that was true but, when they touch my Cable Lock it'll make their ears bleed and notify me that someone is trying to tamper with Any part of my bike, not just the lock, from atleast 20 meters away while in any building, while you can sit there silently never knowing if someone is doing This to your bike .... https://www.cyclechat.net/threads/boardman-cracked-frame-repair.225064/



My advice? Buy smart not strong. :whistle:
