    Brompton: Mounting adaptor for carrier block

    Could any members suggest where I can find , online, a mounting adaptor on top of the existing Brompton carrier block ?



    Available Brompton bags are too big for my needs. I'd like to clip on the block a small/narrow bag.

    There is a German online store which offer an adaptor to mount on top of the existing Brompton block. I could no longer find the thread where a member did mention this site.

    Or better, any idea on making a custom made adaptor myself ? Thanks.

    It would probably be a lot simpler if you could go with a pre-existing option.

    Out of curiosity, how big/small a bag are you looking for? The Carradice Original, Brompton C, and Brompton S bags are 25, 22 and 20 L, respectively. Are those all too large for what you've got in mind?

    ECB, thanks for the suggestion. I did look at the Carradice and the Brompton as you've suggested but they too wide at 420mm( 16'' ) . I prefer half that width @ 210mm ( 8" ) or narrower.

    I have the " folding basket set" . . . and it's great for the groceries. But I need an alternative smaller bag sometimes. I'm looking for a narrow width rather than small capacity.

    YEESSS !.... Thanks a million , Brommie. You must be the one that posted the thread I was looking for.

    I really like those little front carrier you have on those pictures. That's what I'm looking for.

    Do you recommend any other useful carrier ? The one with the plastic map cover look very handy for touring/sightseeing.

    The one with the plastic map cover is from AGU. It came with a bike my father once bought. He didn't use it.
    It's a quite common bag but useful for light touring.
    With the adaptor all bags with the KlickFix adaptor fit.

    Badmother interesting. As you know from other post this is what I did to mount the Brompton fitting onto a non Brompton bike.






    Though links (youtube) show a bespoke part. Mine is a DIY solution but interestingly its similar in the way it attaches to the head tube. I had not seen that bespoke part before I designed mine. With mine you just need a stock Brompton block which you then modify using three jubilee clips to attach it. Wrapped in black tape to make it look less industrial

    Regards

    Same forum. Here somebody found a way to atatch the front part of a clickfix handlebar mount to hang a bag like you would hang a Carradice saddlebag.

    http://www.bromptonauten.de/phorum3/read.php?1,9128

    In the same thread somebody mounted the clickfix caddy (for mounting on stem or seatpost). To this one is atached a homemade "adaptor" and the Brompton luggage block mounted to that one again. This way you can hang a light brompton bag from the seatpost.

    A more elegant solution was posted in the Yahoo Brompton group (I think that is where I found it). Just hanging a Brompton bag w frame from the two loops (made for hanging saddlebags) on the seat. Two leather straps was used- one trough each loop in the saddle and trough the frame (handle I think) of the bag. Not ment for heavy bag on long trips, more like when you use the bike as a lugage trolly. I mus look for the link for that one.

    Edit: Good thing about that system is that you can park the bike (rear end under bike) with both bags still atached. This is much more complicated if you use the rackpack). I guess the seatpost could be lowered to make it more stable to roll it like that but it is doable on flat surface.

    Jerrysimon: Thank you! I was hoping for peopel to post pictures of such solutions here so we could find most of it in one place. I am going to post some pictures over the next few days on things I have done about luggage and plans I have.

    I think it should be possible to start with a brompton frame and butcher it and use mainly the plastic piece that is atatched to the lugageblock and then atatch parts of a clickfix handlebar mount to that. Got the stuff in the house so I am going to post some more on luggage soon.

    Anyone else?

    Somebody in the Yahoo Brompton group cut a B bag frame down to fit a Ortlieb pannier (mounted the pannier much like you do on a rear rack). The frame was made narrower first so that it had the same width as the Ortlieb pannier. I fear that you need to be a member and logged in to see the pictures:

    Rixen and Kaul parts 0273S/KT 814.. was the part numbers
    gleaned from seeing this thing before .. but no US sources ,
    Just .. Japan and Germany

    From the steel carrier bag frame type fit, onto the carrier block,
    instead of the lighter nylon and aluminum one, sold now..

    people have drilled out the PoP rivets and narrowed down the newer bag frames
    and modified them to use an Ortlieb Back roller bag as a waterproof touring bag..
    that link above

    one could further narrow them and use a front bag too.

    This is a great thread. I had looked for this type of info before and had no idea people had come up with so many alternatives for carrying different luggage on the front of small wheeled bikes.

    Would the 7-litre Mini O-Bag not work?

    For sure, but we got that option not long ago and some some peopel would refuse to pay for it. I buy two or three of each for the bromptons so I buy what we really need or want and look for alternatives if I can.

    Some peopel have DIY as a lifestyle choice. Do it yourself if you can. I guess I am one of those.

    For me the main reason is I am fed up with having so many different bags lying around the house becouse each one is really only good for one thing. A Ortlieb pannier can also be used as a pannier on another bike. The person who did the pannier ride a yellow and black B. He bought a yellow & black pannier to use with the bike.

    I sometimes grab a bag and go. I remember I had my wallet and my multitool the last time i rode a bike so it is all good. Then I need the multitool or some money and realise I had a different bag and a different bike the last time.. Then I want to go somewhere by car and do not want to swap all my stuff to a different bag, and then again to ride in the afternoon.

    If I meet my son after school and we decide to swap bikes I want my bag to fit on his bike and his bag on mine. Or maybe I just want to take some of his load.

    Then if you go touring on your bike You`ll find (at least if you are a compulsive DIY`er) that you need to change something before the next trip..

    You say no US sources, but also where I live I can not get them locally and trying to locate a dealer and then travel there would be expensive. I buy them online from abroad, mainly UK.

    A B carryer block could be altered to fit most bags yes. But that would add the price of the block to the price of each bag plus the bag could only be used on a bike with a B carrier block. If you turn the B frame into a adapter (or buy a adaptor if you can) you can use that bag on bikes with a clickfix adaptor installed OR bikes (not only B`s as we have seen on several postings) w a B lugage block fitted.

    Jerry, I'm about to do the same hack for my Cresswell. What is the function of the top jubilee clip?

    Good question lol

    I am not sure it is needed to be honest. In my nature to be over kill when it comes to engineering I guess

    I do however think its worth fitting the bottom one, as it helps take the load on the luggage blog with a heavy ladened bag. That is where I think my solution scores over the one that just has the two clips going around the bracket and attaching to the head tube. Mine has been rock solid for over a year and sometimes I carry eight pints of milk and couple of bottles of cider/wine with not problems.

    Next time I do some work to the bike I may remove the top jubilee clip. Thanks for making me think about it

    PS When you cut the slots for the middle clip make sure you get them as near to the flat face inside the block as you can. Also once the clip is inserted try and push the part inside as flat against the flat surface as you can. The mounting block itself is made from quite dense material and cutting these slots does not seem to weaken it at all. I also found that the semi circle round profile on the back of the block fitted my head tube diameter really well. That may not be the same with all head tube sizes/diameters. Oh and finally I think I had to trim the release lever a little on the back as it fowled the jubliee clip when I pushed it to release the bag.

    Regards

    Jerry

    Oh, I fully get the DIY side of things. I was just suggesting it because the OP had said that the available bags were too big for their needs.

    And I just now noticed that this thread started in Feb, 2010. Nevermind.

    More luggage stuff: Found this in a British forum. Somebody mounted a B carryer block on a 20" folder and also made a "frame" for a bag out of oak wood: http://yacf.co.uk/forum/index.php?topic=53284.0

    that bin kludge looks like it only stays on with the weight of the thing ,
    no catch to use the part of the frame clip included for the purpose..

    the Bag Frame itself is available separately "£20.00"

    I am not trying to say this is a great solution, just collecting what has been done. If you take the time to read the person who did it say it is not superstrong.
