    older BOB trailer upgrades - looking for input

    Hello,

    I've got an older BOB trailer from before they went to the new pin design and I'm playing around with upgrade ideas.

    1. Upgrade the fork to the newer style and probably go with the longer one.
    1.a. Does anyone know if the older forks measure equivalent to the standard newer fork? I'm guessing the longer 28" option is longer than the older original forks.

    2. Upgrade the trailer wheel/hub. I read a few years ago where someone replaced the hub to upgrade that, but don't know if that is really an issue with the older stock hubs. I think the one I read about had some sort of premature bearing failure of some sort, maybe, or else the guy just wanted to upgrade for the sake of upgrading.

    3. Convert the trailer to run a 20" wheel instead of the 16" wheel which should give me some more options for finding tires and running decent BMX hubs.

    4. Sell my older but in good condition BOB Yak and then use that money towards buying a new BOB Yak.
    4.a. I'll have to run the numbers, but I'm thinking that if I want to update the fork and add on a DrySak (mine has the older black canvas breathable bag) then it might make sense to just buy a new trailer and sell the old one.

    Just looking for input and opinions on these. Thanks in advance.

    (Talking with myself here, listen in if you want to )

    It looks like it would make more financial sense to keep what I have and upgrade the fork if and when I feel the need to, that takes care of #4.

    I'll have to test it on a road bike I'm about to put fenders on to check clearances and see if the longer fork will buy me anything, that should eventually take care of #1.

    #2 & #3 will take a little work in the garage to see what I have laying around and to see how a 20" wheel I have with a high pressure road tire fits on my current BOB. I'm thinking rear trailer fender clearance might be an issue, but I won't know until I test fit it.

    If anyone needs me I'll be off in the corner drawing imaginary pictures in the air as I think this through further.

    Looks like #3 will not work out. I eye-balled a 20" wheel next to the trailer this weekend and it looks like I'd have to modify the rear facing dropouts to run a 20" wheel. Bummer.

    (I appear to be talking to myself, perhaps I should have posted this in the Touring section, but I figured that trailer discussions would be better down here in Utility. Oh well, maybe it's just a B.O.B. thing, life goes on. )

    My old Yak has the original 16" wheel and hub, the previous used to tow it from Arizona to L.A. fully loaded. Its been used hard but will probably keep on for years. "If it aint broke..."

    I am a common proponent of "if it ain't broke..." , but also have enough practical experience to know it is better to fix something if you're certain it will not last the next adventure. I think I'll just start doing some dump runs with it hauling off scrap bike bits to the local metal recycler and see how it holds up. Going to have to put the gnarly tires back on the commuter bike first though. I appreciate the input, thanks.

    fietsbob,
    Thanks, I'll keep that one in mind, might be handy to build up a spare wheel ahead of time "just in case" if I can find a spare rim. Otherwise it can wait until the winter settles in and will give me a basement project. Let me give it some thought.

    Wouldn't the 20 inch wheel raise the center of gravity? I know my BOB loaded can have issues when it starts to lean with the 16 inch. Two inches higher might not make much difference, but it might - just a thought.

    That is something to consider and I'll keep it in mind, but right now it is looking like a 20" wheel won't fit without major modifications to the dropouts so I'll be sticking with the 16"er for now.

    perhaps a fiber reinforced nylon 16" wheel, ie, Skyway, etc., will fit ..
