Yes, can't argue with that, the front carrier system of Brompton really rocks. The longer truss also has less load capacity of 7Kg?

Now, If and only if brompton can also have a QR system rear rack ...




H&H with Klickfix GTA QR platform


No hand still balance. Must be over 20Kg

10kg in the front already helps for the groceries.

In the back, a rack/trunk bag is a lighter alternative:

• Ortlieb Trunk-Bag RC, Bike Basket
• Agu Yamaska Rack Pack 475

Winfried

And there's always the Burley Travoy alternative, straight from the supermarket to the fridge.

This chop stick carbon ti rack is quite expensive ...

Winfried

It works fine even with a $50 aluminium rack, though ;-)

I might get a second-hand Strida, and was wondering if the Brompton luggage block could be doctored to fit on that frame :


For those who have engineering experience, do you think drilling a couple of holes to hold the block in place with hose clamps + a piece of inner tube might do the trick?

Thank you.

fietsbob

Maybe not just a hole, Im thinking too thin .. but instead set some riv-nuts

at least no fork steering tube behind it , which is why Brompton brazes on a piece of steel to the outside of the head tube .. screw does not touch the fork turning within the head tube..

I'm guessing i don't own one of those, but it looks like steering is the hinge behind it's steering column.

is that just a hollow pipe?

Without being an engineer - I hope you don't think about drilling holes in the frame tube?

And also you hopefully did not overlook that you're putting weight on the steering - and not on the main frame.

Winfried

The drilling would occur in the Brompton luggage block, and thus, would not affect the frame.

The sterring might be slightly affected while the overall stability might be improved by adding weight on the front wheel (wheelies when riding uphill).

BromptonINrio

dont buy strida!
you south parts suffer!

Blackstrida_A_

And a bit later you published at Stridaforum the question
Drilling through headtube to add Brompton luggage block?

- how does that match, are you just kidding or what?

Once again:

Do not attempt to drill ANY additional hole into the Strida frame tubes!

I advice that after over eight years of intensively studying Strida technics - jfyi.
You have been warned.

Winfried

Because generally speaking, I like to check all my options before making a decision. Is this wrong?

#ChillOut

As for putting weight on the steering: This is exactly what the Klickfix adapter does… as well as front panniers. Why would that be terrible on the Strida?

BromptonINrio

Hey my friend, my suggestion is to try strida before you buy.
the frame is so stiff that the private parts does suffers a lot in potholes...

Winfried

I have a simple solution that I've used for a few years now with my Brompton: I ride around potholes.

Low tech is good tech®

Blackstrida_A_

So either you're still kidding - I can't imagine that you never felt/experienced the very negative effect in the handling of the steering bars while putting weight on it...
or I failed to point out the difference here between Brompton and Strida - therefore I give it another try in different words.

You really want to put weight on the moving parts of the steering?
I mean that is a bad idea always - totally independent of the brand.

That is what clickfix does, correct - but that must not mean it is in fact convenient to ride.
And this is NOT what the Brompton block does, as the block is connected to the frame it won't affect the steering behaviour.

On a Strida there is no front frame (part) existent - all we have is the (moving) front tube.
Therefore it is impossible to mimic the technical function of a Brompton block on a Strida bike.

You can glue it, screw it, weld it, whatever - it will not work like that on a Brompton.

Btw, you wrote earlier in this thread


hopefully you found the contact details meanwhile - they are nowadays at above linked page; just click Imprint.


True - for bikes elder/including Strida 3.
False - for bikes newer/including Strida 5.
(At least in Canada, Europe and Korea are all parts available.)

Please blame your local distributor for parts suffer (or perhaps yourself for being too lazy to search the www?)
- but not the manufacturer/brand!
Thanks.



Excellent suggestion, highly recommendable, thanks.


Congrats - you are the first person worldwide mentioning a stiff Strida frame!!
Your price - you won the Strida distributorship for Brasil...I believe...

Winfried

1. Carrying a backpack is not convenient either
2. Besides Klickfix, touring bikes often have front panniers, which both affect steering.

In practise, would it be so terrible to carry a few kgs at the lower end of the head tube on the Strida? Have you tried it?

--

Edit: I don't have a single-speed Strida handy to check, but at least on the EVO, adding a Brompton block or Klickfix adapter doesn't look like a good idea, as it'd have to be quite high up the steering tube anyway, which would make it even more uncomfortable. And considering the size of the rear rack, it looks like riding a Strida EVO = backpack.

Well that's a huge bummer... I worked really hard on developing this adapter and bikegang just swoops onto eBay with a copycat product and undercuts my price? Nice. It's not like I'm making any significant income on this, just a jerk move. But I guess that's the world we live in...

For the record, I explored the angled interface and found that tilting the bag forward put the bag out in the wind too much, and even with my handlebars all the way down braking/shifting performance remain unaffected with it straight. What do you guys think? Am I wrong?

bike.gang.uk

This is quite an easy and straight forward concept, and this discussion is here for many years. We did made some sample back in 2015 (CNC machined just not cost effective enough to sell), if you scroll back this thread. I wouldn't say yours a copycat, would I?

Here is another commercially available one newly out, made by a bag maker who wants to fit the bags between bikes. Prettier than hand milled but probably too expensive to sell by itself.

Winfried

Are any of those Dahon/Tern-to-Brompton adapters available for sale on eBay or AliExpress?

kayakindude

I do want to say thanks for your efforts. Mine has worked flawlessly since I threaded the screw hole. Even took it on vacation to San Francisco, where it worked great as our gear bag. Just popped it off and carried it into the museum's and attractions.

BromptonINrio

The adapt we made for brompton block to work on dahon frames are strong and solid.
realy make the bike more usefull and are way better than blickflix alternatives

Winfried

https://www.bikeforums.net/20263288-post168.html

How can we order one?

BromptonINrio

There is a instructable showing the design...so you can make your own version and print it in a 3d printer!

Winfried

Unless it's further back in the thread, you posted pics but no link.

https://www.bikeforums.net/showpost.php?p=20263288&postcount=168

Googling for "BromptonINrio instructables" returned nothing.

Also, is a 3D-printed design solid? I wouldn't want to have it break on me while travelling.

BromptonINrio

Hey my friend,
to use brompton block on dahon lugs i tryed 2 methods and bolth has proven solid:

first is to use a regular brompton front carrier blocks and enlarge the holes to fit dahon bolt spacing.
after, you need to fill down about 7mm of dahon lug welded in bike.
in the end the two bolts need to go in the proper angle and the carrier block need to fully embrace the dahon lug.

second is to buy and adapter:
Here you can find many in all materials https://www.shapeways.com/product/QLHYDKUBE/brompton-carrier-adapter-for-tern-or-dahon-folders

The last subject is that if you can print either your carrier block or your adapter block...and you can pri t bolth.
