Customer Reviews for Milenco Coleraine 12mm Chain Lock

Milenco Coleraine 12mm Chain Lock
September 13, 2020

Very strong, but too short to pass around a post.

I bought this chain after an excellent review on Bennetts Bike Social who had benchmarked a large number of chains. This was about the largest that was still portable enough to carry on the bike (circa 5kg). However when I passed it through my rear wheel it was too short to loop around a lamp post.

Great chain

Easy to use and very sturdy, I use it at home only as it is quite heavy. Really satisfied with the purchase.

Sturdy kit.

Great bit of security kit, fits through my ground anchor and through my bike, feels very secure, great locking mechanism, not sure if it's ideal for external use as no weather cover over keyhole, otherwise a very good chain and lock.

Solid, well thought through.

This chain is solid square section, with the protective cloth sheath. The chain has great and reassuring weight to it and the covering feels pretty durable. The locking mechanism on the end is shrouded in plastic which is good for passing through the wheel and not chipping the paint. Only thing to consider is the clearance between the brake disc and the wheel, if it's a struggle to get your hand in behind the disc, this might not pass through easily. The chain would, but then you have the chipping consideration. Good quality both physical and visual deterant. Maybe not the chain to take with you as it is very heavy and bulky.

I bought the lock to take touring but might be a bit heavy. It is the 1.4m. Easy to use locking mechanism. I would definitely recommend it.

Extremely happy

Very impressed with the chain lock. Unusual locking mechanism. Bought to replace an Oxford triplock which was cut with an angle grinder. Chain seems to be very substantial. Bought the 1.8m which is just long enough to go over the rear seat and through the rear wheel.
