Hi,

What are you folks using for security for the quick release. The front quick release skewer measures approx. 18 cm, there a security skewer available for that size? What are you guys using to secure the seat?

Regards,
Reggy

I'm protecting a Cloud 9 seat and a Redshift suspension post worth over $275 together, so I replaced the quick-release clamp with a conventional post clamp https://amzn.to/3GzPsAv in 31.8mm size, then I replaced the hex bolt for the clamp with a tamper-resistant Torx version https://amzn.to/3DCd8lD in 6x20 size.  Of course, you'll need a special Torx tool for that bolt: https://www.homedepot.com/p/Husky-Magnetic-Tamperproof-TORX-L-Key-Set-9-Piece-HLAMTXK9PC/207190358  - I recommend you carry that tool on the bike in case you need to adjust or remove the seat in the field.

Pic below; hope this helps.  The blue tape is just a position marker to reset the seat to the same height while I was adjusted the Redshift tension - I eventually added another seat clamp https://amzn.to/3lR8r1q in 28.6mm (not easy to find this size) to the Redshift post itself, so now I just drop the seat assembly down until it stops with one clamp on top of the other, center it and tighten the bolt for perfect realignment.
Shucks Ma'am, I'm no "Hero Member", I just like to wear this cape.

The clamp with the torx bolt is a great and simple idea. But if like me you share your bike with your wife its needs to stay adjustable. A low level of protection could be a simple small cable looped around the frame of the seat itself (and around the bike frame) with a small combo lock.  Or a better cable looped around whatever locking method you use to keep someone from stealing your entire bike....   

I'm considering buying a brake disc lock (common on heavier motorcycles, not as effective on a 70 lb bike of course), and then you could run a thin cable thru the disc clamp.  I'm considering this Kryptonite K004776 disc lock because it has a loud alarm built in, but I'm not sure how much you have to move the lock in order for it to activate - would just picking the bike up be enough?  But if it is just to use while in a store (and not overnight outside your home), it might be enough.  https://amzn.to/3sFoaTZ
