    source(s) for long chainring bolt set?

    I'm not having no luck finding any. This will be for a 110 BCD dual bashguard setup.

    Yes. Current ones are 8 or 9mm doubles. Since I'm gonna need spacers as well, maybe I can get the bolts you linked to and use my existing double nuts (no pun intended )?

    Yes, that's exactly what I would suggest doing.

    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. ;)

    This set of bolts:
    http://harriscyclery.net/page.cfm?pa...ils&sku=CR1202
    are designed to hold three chainrings on the same BCD. They're for old-school triples, before they started putting an inner circle of bolts for the "granny" chainring.

    I saw these too. But don't I need a special tool for the nut?

    If I need something, especially a small part like that, I'll go to the shop where I've decided to build a relationship. For me that means one shop about 15 minutes away from me (on bike, driving it's like 8 minutes).

    I've sat there, dug through their box of maybe 300 different chainring bolts (I needed them for my track bike), found what I needed. I also installed a set of take-off cranks (theirs) and fiddled with some chain stuff.

    Then, a different day I installed new cranks/bb (I bought from them, special order), chain, and I think fiddled with some axles or something.

    Because I built a relationship with the LBS (over about a year), they treated me well. They gave me the chainring bolts, told me to use the cranks free. They try and give me a discount, I ask them to charge me full price.

    In return I try and buy things from them (SRAM track crank/bb set). I give them things I don't need, like the brand new english threaded BB that came with the track cranks. I ride with them. I've helped them change tires on a customer's bike. And I know that I can count on them if I need anything.

    For something as minor as chainring bolts, you really ought to go to an LBS. This is especially true if you're trying to make something work that you haven't done before. It's too late now to "build the relationship", but if you had a decent one, I bet they'd be willing to let you dig through their chainring bolt bin, fiddle with whatever and make it work, and send you on your way for a few bucks.

    You'd need the same special tool for the nut regardless of which bolts you choose. The advantage to those Harris bolts is that the sleeve nuts extended all the way through the entire sandwich. Your current nuts with longer bolts would not align the chainring as well as the Harris bolts and nuts.

    Thanks. I understand about the alignment. My current bolt set are 5/6mm, outside/inside.

    Oh, you've got those kind of nuts.

    The old-school triple bolt/nuts sometimes need a tool to keep the nut from spinning, but I don't have one. I just use a big screwdriver. If you want to spend an excessive amount of money, you can get this one made by my buddy Brett: http://www.biketoolsetc.com/index.cg...em_id=EV-CSPAN . Almost 20 times the price of one from Park Tool: http://www.biketoolsetc.com/index.cg...tem_id=PA-CNW2 . Usually, though, a little oil on the threads will allow the bolts to tighten everything together without anything holding them on the back side.
