Disc locks?

Reckon it's worth investing in one? I was thinking about getting an alarmed one. Bike already has an alarm but I was thinking the more the better?
At the end of the day disc locks are just deterrents, if they wanna steal it they can so surely an alarm will deter even more.

I agree with your last statement. I have one but always forget to use it. Wouldn't get a non alarmed one. Front mudguards are expensive.

I've used one and it has saved my bike from being nicked once as they got fed up dragging it (not master bike thieves) and it made a reasonable difference to my insurance at the start. Now I just use it as a deterrent, I've not used an alarmed one but once I got into the habit of putting it on every time and taking it off every time I don't forget. You can get reminder cables too, but the alarm might remind you even better!

If you already have an alarm, then I don't see the point of spending too much on a disc lock. Sure it's a physical and visible deterrent but if they are going to pick up an alarmed bike and chuck it in a van, would a disc lock make much difference?
A good chain fixed to something solid might be a better option to back up your alarm.

Alarms are not visible so the scrotes may have a go and damage something before they trigger the sounder and scarper. The lock will put off opportunists like this so it has merits. Agree on the above though - the determined gang-with-van will still have it and a stout chain to something solid is always a good idea but harder to carry around.

I was advised to use the disc lock on the rear wheel. It's easier for a thief to take the front wheel off than the rear. Probably quite unlikely to happen, but it's no effort to put it on the back, and how annoying would it be to come back to find just a wheel with a lock on!

It works just as well, I put the reminder cord through the wheel and up to the tail tidy so I can see it as I'm approaching the bike

Okay then, I think what I'll do is just by a cheapo disc lock since I do already have an alarm and they're not quality enough theft protection to be worth it. And I'll save up and get a decent chain. Maybe an almax chain?

A number of disc locks don't fit on the rear disc. It's also a bit less visible, and I doubt any bike thief would ever remove a wheel to get around the disc lock, as then the bike won't roll anyway.

Have a look at Pragmasis chains too. I think they do a lock that doubles as a chain lock and disc lock so you can kill 2 birds with 1 stone

I do not know if this is true, but I have been told that in general, people ignore car/bike alarms and then bikes not actually fixed to a ground anchor can just be lifted into a van anyway.

My bike is fitted with a Datatool C4 alarm and that has always been sensitive and good. I also have a cheap but very visible Oxford Disk lock for the front with a coiled cable to handlebar to remind me it is there and also a heavy duty Kryptonite chain lock. When out in Bristol or anywhere I have to leave it unattended for more than five minutes, I use both locks.

My way of thinking is to make my bike as difficult as possible so that any casual thieves passing by will choose an easier bike to steal than mine, a tip I learned when I used to commute everywhere by pushbike.
