I was looking into upgrading my current skewers to security skewers, e.g. Pitlock skewers (These are skewers which are designed so that its harder to remove a wheel without a specific key provided with the skewers).
An example is here:
(From Peter White Cycles)
My bike has horizontal dropouts, but front facing (i.e. not a track forkend, in contrast to this question).
The Pitlock FAQ states: "If you have horizontal dropouts on your bike's rear wheel (horizontal and open at the rear), we dissuade you from using the Pitlock system.
Usually (almost) all rear wheels are assembled in vertical dropouts (opening diagonally towards the bottom). Here the assembly with PITLOCK works without problems. "
They specifically highlight track-style forkends, but not horizontal dropouts which open in the front. So, can Pitlock skewers be used safely with horizontal dropouts? If so, why can they be used safely with horizontal dropouts which are front facing, but not track forkends?
An example of the dropout types is here (mine is similar to the second one from the left on the top row):
(From Sheldon Brown)
The Peter White page claims this is due to Pitlocks being unable to exert enough clamping force (similar to some aluminum QR skewers, since aluminum can't bite into the drop out enough), but Pitlocks are made from steel, so I'm still not sure why the track forkend was specifically highlighted by the manufacturer but horizontal dropouts were not.
