    Preventing theft of allen bolt parts

    What do you guys do to prevent theft of parts secured by allen bolts? I lock up my frame, rear wheel, and front wheel with one u-lock that goes through all 3 together at the rear. Even with this, I still had my fork, stem, handlebars, stem, and seat stolen.

    What are my options? I've seen those bolts which have specific cut keys unique to each set, are these worth it? I've also heard putting a ball bearing in the allen bolts or putting superglue in them for a deterrent. Anything else?

    ride a crappier bike, something you don't need to worry about locking up, or just use copious amounts of locktight on everything so that people give up when trying to remove things

    Do a search for tamper proof machine screws. They make a allen head screw with a little stud in the middle. You use a special hex head wrench with a drilled out hole in the middle to install and remove them.

    This. Make your "everyday" bike cheap, ugly, and undesirable. But still mechanically solid.

    drop a bunch of caltrops around your bike.
    bonus points if you dip the caltrops in cow poo
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    Yeah it sounds like:

    A) You are locking your bike up for way too long and
    B) Your bike is a desirable target for thieves.

    What the hell kind of thief steals a fork?

    Lol I guess OP locked his front wheel down.... there's no way to lock up a bike fork anyway.... all you have to do is to detach the locked front wheel, remove the bike stem via stem screws and starnut screw; and then fork can be easily slipped out (assuming OP had threadless)....

    That is really unfortunate, OP.

    This thought has never really crossed my mind, mainly because the whole bike is usually stolen where I am from.

    I was looking for something like this a few years ago. I could not find anything in stainless, metric, in small quantities, from a place that will sell to you without a business license. Do you have a source?

    You can buy them at McMaster Carr. Great company to deal with.

    The bike was stolen from my campus on the busiest walkway. I'm actually surprised no one stopped them or saw it happening. It was stolen within a 50 minute period. I have a feeling someone had watched me, knew my schedule and what parts they needed and got it done quick. Unfortunately I cannot bring my bike inside. The front wheel I keep on quick release and lock up with the rear wheel and frame. They stole everything else possible, except the crankset/pedals.

    Thanks for all the recommendations, I may end up going with tamper proof hex screws or one of the oddly shaped screws for more protection. I've temporarily rebuilt the bike with semi-cheap parts.

    Sorry you got your bike stolen, but this definitely confirms what I said earlier:

    Nobody is gonna go through all that trouble to steal the cranks off of a ****ty beater conversion.

    Sounds like you need a "campus bike".
    Which, it's true, won't impress the girls quite as much.

    But I'm guessing walking home with your arms full of whatever is left of your bike doesn't impress them either.

    I really feel sorry for you guys that have to worry this much about your bike. I can go anywhere in town and lean anything from my Langster to my Tarmac up against a tree and not worry about it being gone when I return.

    Where do you live?

    And when/where do you next plan to leave your Tarmac leaning against a tree for an extended period of time?
