Surely

I want to pick up a set of security skewers for my new Trek 7.3 FX.

I will be utilizing Sheldon Brown's lock strategy.

I'm considering these Marin Security Skewers, but I can't find any further info/reviews on them. I emailed Marin a few questions, but haven't heard back from them yet. Anyone have any experience with these skewers?

If not the Marins, any other recommendations?

Thanks....

Those 5 sided "slow release" skewers are sold under many different brand names. They are better that quick releases, which take about five or ten seconds to remove without tools. These ones take at least 15 to 20 seconds to fully remove a wheel with some vice grips or a pair of pliers.

Basically, the Marin ones will protect your wheels and saddle against opportunistic kids and mindless vandals, but if you are parking in areas where the thieves are marginally competent, use multiple locks and bolt everything down or use some of these: https://www.pinheadcomponents.com/

The key is a bit of a pain to use, but since the skewer has no protrusions for theives to grab on to, it turns a 20 second hand tool job into a five minute grinding production. Odds are there's easier prey nearby. There is also a company called Pitlock, I think, that make a similar product, but it is more complicated and more expensive.

Those pinheads aren't bad but you can easily take them off in 20-30 seconds with just about any reasonable pair of pliers.

There's no good solution here short of spot welding.

ghost gave the best advice:

use multiple locks and bolt everything down

Many folks remove the front wheel and carry it with them.

these are the best available, search the forums for Pitlock and see the feedback

Theives may find it easier to steal your bike in it's entirety, instead of just the wheels given how easily most locks and cables can be cut. Most locking skewers offer only a a false sence of security to the owner. Most are also quite heavy.

I use skewers that require a hex key to undo them (something most people don't normally carry with them), and they have the added advantage that they are very light weight.

If you take security seriously and must lock your bike up, then focus your efforts on locking it in a high-visibility, high-traffic locations with one of the small number of bike locks/chains/cables that are capable of keeping even the most determined theives busy for a couple of minutes.

The only time I lock one of my bikes up outside is when I'm touring.
