Ron, I was tinkering with my Zizzo today (modified the stem so I could lower the handlebars to where I like them) and needed to shorten my cable housings to keep them tidy. As I was planning to shorten the front brake cable, I remembered seeing this photo of your FSIR Spin 5 and decided to copy this simple but elegant cable routing:



I am quite pleased with the result (little things make me happy):

This is so much cleaner and a test ride confirmed it performs like a champ. I did replace the original 90 degree noodle with one that has a 110 degree(I believe) bend to provide a better entry angle into the noodle for the housing and cable.

Thanks for giving me one of those "why didn't I think of that" moments.
Lookin' good, Geezy. Perhaps even better than mine, with that black wrap-around thingy on your cabling. Little things still matter and can provide great returns on aesthetics and function, as well as personal satisfaction. 👍🏼

Last week, I installed the RD and cable housing on my FnHon Storm. I inserted the shifter cable in the housing, ran the housing through the frame cable guides, attached the cable to the RD and dialed in the indexing on the RD. Shifting was all smooth and crisp when I realized the cable housing was still far too long. I wasn't gonna leave it like that, of course. I have dignity, self-respect and standards, after all. So, I undid and did all that again in order to cut the housing to size. This was how it looked in the end:


No sloppy protuberance in the front or extension beyond the front block carrier, no sloppy protuberance at the RD either.

There was also the haptic pleasure of cutting the housing like a hot knife through butter with this new cable splicer I bought recently.


Is chrome vanadium steel top material? I don't know, but these things sure cut.

I am a firm believer that how you do something is how you do everything. I don't do half-assed.

Just an unsolicited suggestion, alter the angle or Brompton Block mount by making a shim to compensate for the present angle.

I actually remembered -- and heeded -- your earlier warning that the angle of the front block carrier may make mounting and unmounting bags difficult. So, I went and tried it with my own bags, and though the fit is tight, mounting and unmounting are still possible sans adjustment to the front block carrier angle. I am nothing if not a stickler for detail and precision.

Waylaid on the road again...

...at Kesiman village while heading north out of the city. You can watch National Geographic, or you can live Indonesia. May you ride (and live) in interesting places.

Waylaid on the return too...

The morning festivities were only a warm up for the main event in the late afternoon. On my return ride home, I got caught up in this procession making its way to the main pura for the Mendak Bagia Pulakerti ceremony.

Bikes: Zizzo Urbano

What is the status of the design patent for the FSIR Spin? Is there some explanation as to why other manufacturers don't attempt to clone it? For that matter, why did the original manufacturer discontinue its production?

I don't know.

Litepro did clone it. I forget the model name. I tried to get one, a frame, but they've been discontinued and are impossible to find.

For that matter, why did the original manufacturer discontinue its production?
Don't know, but probably poor sales and limited marketing. It was never sold in my home country, the largest and most populous country of SEAsia, and second most populous in Asia-Pacific. The few pieces that did make it in to the country were brought in individually by enthusiasts. I bought and brought this Spin 5 in from Thailand, and my Spin 3 from Singapore. GTA, an infrequent channel participant based in China, one who owned and raved about the FSIR too could probably tell us more.

Litepro Leo was the name of the clone.

FSIR Spin 5 folded


Free-standing when folded -- a real fold -- with no need for heavy, fugly rack, and light for a 20" folder at 9.6kg out of the box.

Back at home again, washed, cleaned and none the worse for wear after the 900km Tour de Malaysia & Thailand 2024.



Its prior overseas tour of South Korea is documented​​​​ here.

Oh, yeah, and that Tern Luggage Truss mounted on the Dahon-type front block? Once again and as in several previous tours, it worked out great, zero problems! 🥳

Hi Ron! Are these 406 wheels, and 1.75 tyre? I am impressed you have managed to have reasonable ground clearance with such a big cassette! I am using Sturmey Archer CS-RF3 hub to achieve wide gear range, but your solution give me hope that I can build much lighter folder next time. My current one is 14kg, and will be down to 12.9kg after some upgrades.

Ron has been scarce around here the past few months, don't know why, but don't be insulted if you don't get a reply. Very knowledgeable guy though on this subject.

I think those are 406 wheels. Ron favors big cushy tires, so I'm pretty sure those tires are at least 2.0" section, possibly a bit greater.

He has many threads and posts which detail the rear derailleurs he has used for his wide-range 1X cassettes. A real trove of good knowledge for you to peruse. You can click on his ID to view his member page, then click on profile to see lists of his threads and posts.

I see, thank you. I've zoomed the image though - and indeed these are 47-406 tires. Impressive.

Huh, I had tried zooming and couldn't see a thing on those white sidewalls. I guess you did something with brightness or contrast to be able to read the molded numbers.

The fsIr Spin is an old design, not available anymore,.

Many more recent folding bikes with ETRTO406 tires accept tires wider than 47mm: Bike Friday's from 55mm with fenders to 71mm without fenders, Brompton G-line 55mm with fenders...

I am not impressed with tire width per se (having 47-406 by myself); but with the possibility to have such a big cassette with so standard tire width.

The Bike Friday's can also have big cassettes, their widest tires are compatible with cassettes up to 10-44t.

Yeah, but BF:
- does not fold as easy and compact as classic bifold
- is expensive
- is only on US market
