Super-light lock...

[Bmblbzzz]

While unlocking outside the supermarket yesterday, I observed another shopper take out of his pannier a large, chunky D-lock and a long cable. I thought he would use the D-lock to lock to the stand and put the cable through the wheels. But no, he put the cable round the stand and back wheel, then used the D-lock as a padlock securing the two ends of the cable. In effect, the D-lock might as well not have been there, as a thief would simply have had to cut the cable to take the whole bike. On the other hand, locking to a stand outside a busy supermarket in full view of all shoppers and staff through the large windows, the risk is probably rather small anyway.

I use a chain now too but it's a G80 lifting chain so short link which the thief would find difficult to hold while cutting with an angle grinder unless the thief has brought along his bench vice.

Long link chain links can be held with a glove while cutting. When cutting my short link chain to length my leather gauntlet got so hot it stuck to the link and it took me 6 minuits to separate the chain.
With the disc jamming because the short link is hard to keep in position and waiting till my glove cooled enough to get my hand in it again it was difficult to cut.

Weight is the downside though since it's 8mm and 1.5m long along with the stainless padlock the thing is 1.5kg.

I fitted an electrical cable tidy wrap made of a heavy duty PVC coated fabric that wraps around with snappers then secured that with some cable ties. Originally to protect the bike paint but this also has the effect that it's easier to wrap the chain around large objects like telegraph posts etc. (There is nothing you could lock your bike to with a D lock in town except Tesco bike racks )
