    Under seat bag recommendation

    I've cross posted this in "Touring". Probably more appropriate for this sub-forum.

    My wife and I do long day rides on our tandem. We're using an Arkel trunk and an OMM rack, but basically we only use the trunk for some tools and discarded clothing. I'm looking to save weight and replace both with a large bag under stoker's seat. Typical loading would be a heavy Craft rain jacket, leg warmers, arm warms, vest, etc. I can find an alternate location for tools if necessary. Would appreciate any or all recommendations.

    Note: We have an ST Thudbuster to the bag needs to be large enough so that the seat post attachment is below the Thudbuster. This is probably not an issue for an reasonable size bag.

    I have the large ortlieb bag. Not without its problems, but it will probably do what you want. Although I have trouble putting a full size jacket in there with a spare tire. A lot of people I know use a carradice.

    I have actually considered going with a light rack and trunk bag in lieu of the seat bag. I hate struggling with putting things away. I still think that a handlebar bag is best for this, but I haven't gotten around to making myself a rack yet

    No recommendation, but it might help others if you tell whether or not your saddle has bag loops.
    Punctuation is important. It's the difference between "I helped my uncle, Jack, off a horse" and "I helped my uncle Jack off a horse"

    Photo. May depend on stoker seat post exposure and height relative to tire.

    Have lots of room above tire. Photo attached. Also, the seat does have loops for straps.

    I like the Vaude Off Road bag, comes in a few different sizes, good weight to capacity ratio, reasonably priced.

    What bike is that? I was going to recommend the Detours HighTail rack bag, but I see they don't make them anymore. Too bad. They were great. That leaves you with a choice of a large wedge bag like this:
    http://www.jandd.com/detail.asp?PRODUCT_ID=FMW3

    Otherwise you have to go the route of seatpost rack and bag. The rack usually weighs about a pound, plus the bag. Google "seatpost rack bag." We have a Detours Transit box in plain black, which weighs another 18 oz. OTOH, for about the same weight as a seatpost rack, and the identical weight of the Tubus seatpost rack, you can mount a Tubus Cosmo in SS for 650g. Which is what we did: the Cosmo plus the Transit and have a 2 lb. 5 oz. aerodynamic, waterproof, durable, flexible storage system.

    I see that Vaude Off Road bag is about the same thing as the discontinued Detours High Tail. I used my Detours quite a bit for randonnees on my single, for which it worked very well. Less weight, definitely.

    That's my daVinci. Would have been a bit more obvious if I had included a picture of the entire bike.. The Vaude does look interesting and the medium only weighs a pound with a 500+ sq. in. volume, plenty for what we need.

    The Vaude does look like exactly what I need. I certainly have enough seat post.

    These are wonderful. Very versatile. I do have both DX and non DX version for different usage since they use same mounting mechanism.
    Amazon have them at great price.




    Example of DX version


    PS) Don't think it would fit with your rack setup though now that I look at it.

    I was wondering about either a bag like one of those (Porcelain Rocket makes them too, and also some company in Poland that I saw over on the mtbr.com site) vs a Carradice style bag. My saddle doesn't have bag loops though which might rule out the Carradice models.

    You should have plenty of room for a Carradice saddlebag, or a variation on that theme. Carradice has a nice comparison chart of their models online. Rivendell sells some too. The traditional saddlebag is transverse to the saddle so that it can hold a lot without sagging into the rear wheel; you may not like its looks. It doesn't add much, if any, wind resistance, though, unless the cyclist (stoker in this case) is rather thin.

    If your goal is to save weight, I wouldn't get a bag that requires its own rack, since that will eat up some of the weight that you will save by removing the rack. You might also want to compare published weights for your current rack + trunk bag to any potential replacements. On a tandem, a difference in weight of a pound or two seems pretty small when compared with the total weight of bike, two riders, and gear. I like having extra carrying capacity on my bike when I'm doing long day rides, in case I run across something I want to buy and take home--books, half a dozen ears of corn on the cob, a basket of peaches, a bottle of wine or six-pack of beer, etc., depending on where I'm riding and the season. Competitive cycling, including randonneuring, is a different matter, of course.

    If you have an arkel tailrider why not just get ther randonneur rack? About 18 ounces. Not sure what that dynarack weighs but I bet it ain't that light. Other than relevate which always seems out of stock, not sure what could be lighter. Carradice saddle bags may have the lighter "bagman" to support them but the bag itself would be a little heavy.


    edit oops I guess a little late . . .

    I think for now I'm going to stick with the rack and Arkel, but I'll probably pick up an under-seat bag for summer use when arm warmers, jackets, etc. are unnecessary. Best $/lb is loosing 15 lbs - costs nothing. Also changing out my double-sided SPDs for A520s I already have since they are more comfortable anyway. I did jettison my CO2 and bought a better, lighter pump. Actually had to use the new pump on last week's ride and it worked just fine, thank you.
