OnGuard has long been known for producing the meanest, toughest locks in the business. We’re the junkyard dogs of security and thieves know that when they see an OnGuard lock it’s time to move on. But who says you can’t teach old dogs new tricks? So we took the We improved our all-tube mounting brackets with an innovative Twist-Lockwhole OnGuard pack and sent them to obedience school. The result is our toughest, most user-friendly line up ever. First off you’ll see a new look. Crossbar, shackle and lock head covers sport new coatings with a bright color scheme that sends a clear warning to thieves- On-Guard protected, time to look elsewhere.

Replacing a similar 20 year old OnGuard lock that still works fine. I can see improvements though. It is lighter and the coating appears more durable. The keys are smaller and one of the six comes with a little led light. There is a sliding key hole cover and six keys. The mount doesn't fit a trek 7500 but I never use it anyway as I store it in the carrier. I'm very happy with this lock; it works smoothly and has never failed.

The shackle appears solid and the extra keys is a nice bonus. However, this came without any lubrication whatsoever. The mechanism are a bit rough. Need to lubricate it first before use. Also, the manual recommends lubricating with WD-40. This is not a good idea. WD-40 is not a good lubricant (if it can be called that at all). It will also attract dirt. Locks like this should be lubricated with a dry lube. I personally used the same dry lube I use on bike chains and that helps to loosen up the mechanism somewhat. I also feel that it needs time to break in as the mechanism does stick at times. I almost feel like I need to sit down and go through the lock/unlock motions a few thousand times to smooth out the rough edges in the machined parts.I think I read some reviewers (not here) mentioned that the mounting is awkward. This is not true. If one were to read the manual that came with it (it's only 1 page), one would be able to see that the attachment piece on the shackle can be twisted to accommodate different mounting positions.Overall, this is a solid shackle.

Antifurto robusto ed abbastanza partirà essere legato facilmente ad un palo di medie dimensioni. Ottimo anche il kit di chiavi fornite a corredo, di cui una con una piccola e comoda torcia elettrica. Un acquisto che consiglio.
