    Another option is to use riv nuts, the fasteners often used to secure water bottle cages to frames. Available in plated steel, aluminium and stainless. You don't have to use a special tool to compress them but it does help. There is info on the net about using washers and screws to fit them. Don't know what sort of loading they are capable of though.

    Mechanically speaking..

    Backed up by the fork steerer , there may not be space, behind/inside, the headtube.. to expand the Riv-nut.

    flange on the inside is what the T nuts offer, as used.. Riv-nuts used there, require essentially, a backwards installation..

    Struggeling to surf and write on a small cellphone but I have some ideas about bags. Recently had a close look at the B basket to make a smaller copy of it and in the process realised how clever the design is.On trip we are renting a cottage and using it as a base so only using one B basket and one clickfix hack when riding around but when traveling to this place we had one small (cabin size) suitcase strapped to a luggageframe on one bike and a backpack strapped to a cut back c frame on the other bike. Works fine.

    I'm prepping for the delivery of my Brommie (probably still two weeks away) by planning for baggage options. I ordered my Brommie with the carrier block thinking that I'd fabricate a rack for it but I took the easy way out and ordered a luggage frame instead. Then a friend gave me a great "Skil" canvas power-tool bag to which I sewed some paracord loops so that I could weave it onto the Brommie carrier frame. The bag happened to be just the right size and the top closes like an old fold top medical bag or I can keep it open like the Brompton folding canvas "basket".

    This is what it looks like.


    I plan on living forever... so far so good.

    Not the best of photos but enough to give you guys an idea. We do not have T- bags yet (planing to sew some) so on our trip to Bornholm we uses one "cabin size" suitcase and one backpack. I`ll edit later to tell you the size (Litres) of the backpack.

    Both worked suprisingly well, but this is of course a way of transporting luggage, not the best if you often need to reach innside the bags.

    Suitcase: rolled well on its own wheels in the cases when we remowed the luggage and bagged the bike. No need to remowe the frame but also it was easy to just put the frame innside the suitcase. Maybe the best solution since the square shape of the bag made it really easy to keep it in place with just two regular luggagestraps. A more rounded suitcase may be less ideal. The two luggagestraps were used on the B`s when they were innside Dimpa bags on the planes and ships.

    Backpack: Suprisingly easy to keep it in place strapped to the frame. The bag has a proper "spine" and I am sure that helps. Later on the trip i strapped the frame to the front of the bag to be able to take it off the bike and carry it on the back a short distance without remowing the frame. Frame fits into the bag.

    AND: The frame I used is a C-frame I bought some time back for another DIY bag (posted under) The frame is quite small since it is cut down to be narrower for that other bag. I have decided to make a basket for this small narrow frame later. I have made the pattern already. Sometimes when I just want to bring a few things for a ride I think the B basket is a bit big.

    I also had a small red/black backpack atatched with a clickfix bracket to a kf caddy. I used this bag on out shorter trips. Son used the small green nylon bag I have posted earlyer:

    And here is the Cut back C frame on the bag I bought it for. Used on our short trip to Copenhagen in May:

    J-B SteelStik

    Steel Reinforced Epoxy Putty

    • Strength 900 PSI
    • Set Time 5 Minutes
    • Cure Time 1 Hour
    • Cure Color Dark Grey


    Great For:

    • Automotive & Machine Parts
    • Exhaust Systems
    • Plumbing
    • Stripped Threads
    • Rust Damage
    • Household Repairs


    SteelStik is a hand-mixable, steel-reinforced, non-rusting epoxy putty that quickly repairs or rebuilds anything made of metal. After mixing, it forms an industrial-strength polymer compound that can be molded into shapes or used to build up, patch and repair steel components. SteelStik sets in 3-5 minutes and after 60 minutes, can be drilled, tapped, machined, ground, filed and painted. SteelStik cures to a dark grey color, is rated at a tensile strength of 900 PSI and will withstand temperatures up to 300║F.
    INSTRUCTIONS
    Cut: Remove required amount of putty.
    Mix: Thoroughly knead putty with fingers to a uniform color.
    Apply: Press putty firmly to the surface to be repaired.

    * For best results use a detergent or degreaser to first clean the surface, then roughen surface with file or coarse sandpaper to provide the best repair.
    Late reply but this gave me inspiration. Have been thinking about glue for several months . I kind of ran out of steam on the subject but I`ll be back! Is it not strange that you knead it with your fingers? I would expect there are always stuff on our fingers that is not good for the glue. Especially since they mention that about degreasing before applying. Can not find this stuff locally (or anything similar) so plse tell me if you have a source for it online.

    I am sure that if you use the right glue and use it the right way you can glue almost anything.

    Some time back BNB linked to this site: http://www.din.or.jp/~wsho/brompton-e.html

    I think I know this company, If I am right they are Japanese and have a hube amount of stuff on Flickr. I have been thinking about adding a second back to existing bags to fit the frame, but finding a good match for the material on the added back is not easy. This link reminded me that of course you can add that extra back INNSIDE the bag, and thereby use a material that does not fit well in colour. Could be a lot of work, but doable if you really want to do it. Remember a frame can be cut down to be narrower if needed.

    There are several instructions on the net that I found trough the Yahoo Brompton group that show what peopel did to atatch bags. Here is some: http://codywms.tumblr.com/post/50695...ompton-bag-diy
    http://www.foldingbikeguide.co.uk/re...0-brompton-m3r

    I like one that may be the start of the T- bag. I used it to make a bigger pattern for T-bags I`ll sew this autumn.
    Edit: Here is the link: http://www.toehead.plus.com/bagmain.htm

    I also REALLY like the steel frames they sell. Looks like the support at the bottom is bigger than on the standard. I know several peopel (like fietsbob) have said they want a steel frame like the old ones. This one IMHO looks even better than the old ones.

    Of course, if you have a strong steel lugageframe the weakest point may be the luggageblock..
