Do you know anyone with a Dahon or Tern to get a side-by-side comparison photo of the two bikes fully folded?

I don't know about the wright penalty for the Physis handlepost. I had a Breezer Zig 7 a few years ago that was just a rebadged Dahon and it's handlepost was extremely flexible. Unless Dahon made improvements I'd take the weight penalty.

Yes, the luggage block is another nice touch that endeared me to the FSIR.

Probably an Alfine 11 if that's the range one desires. It has a gear range of 409%.
Thats pretty close to a 11-46T already. Equivalent of a 11-45T.

No, but I would expect that the hinge folder would be slightly more compact since the folded size is one half the length of the bike. For the FSIR, the folded length is one half the length of the bike, plus the distance from the pivot to the seat tube.

Not much of a difference at all...

Good image hunting! Yeah, for me the marginally larger folded size is not an issue. The FSIR is easily my smallest 20" folder. But those with traditional hinge folders may balk. For me, personally, the protruding pivot-to-seat-tube section is a small price to pay for the increased structural rigidity and durability of no hinge.

I just overlaid the two images in Adobe Mix...

I agree that the FSir looks like a sturdier design.

Maybe a Titanium FSIR is more your thing?



Notice the Bannard saddle.

That is a nice looking bike. The is a second quick release lower on the seat tube. I wonder what that is for?'

Is there someone that sells these online? I'd like to see the price and specs.

All FSIR Spins have two clamps. The second, bottom clamp is to secure the seatpost to the lower section of the frame.

I wonder if they also rely on the second (bottom) QR clamp for structural integrity like the Swift Folder.

Xootr had some issues early on with frames failing because of torsional forces while the bottom QR wasn't clamped tight enough onto the seatpost (some of them were due to seatposts that were the incorrect diameter to allow the proper clamping force).

It definitely cleans up the fold on the FSir having the seat moved to the lower QR when folded though.

From a brief stare at the frame, I would say not so much. The forces are different. Rider weight on the bike will tend to force the swivel joint to separate, and the seat tubes together. That is very similar to the Swift. If the seatpost wasn't inserted into the bottom seat tube, obviously the bike would tend to fold; if the seatpost fit into the bottom section was poor, there might be play but it doesn't seem as if the frame would suffer much worse stress. I do think it would be stronger with the seatpost in properly, though.

In the Swift, there is a very high tension set up in the upper portion of seatstay if the seatpost isn't tight. That's where the early Xootr Swifts tended to fail, even mine which I babied for many years to avoid it.

I actually like the double clamp on my fsir because i don't have to tighten them too much and just good pressure and had zero slip on them, probably because there is two points on the seatpost being held up now instead of one point. Unlike my other folders which need quite a bit more tension to prevent them from slipping.

Abu, if you want to buy a nice wheelset with MTB hubs which one would you buy? Thanks a lot in advance.

Depends how much coin you want to drop. I'd have it built with Industry 9, Hope or Chris King hubs if money is plentiful. Otherwise Shimano SLX or Zee is great value. Spokes? DT Swiss, Sapim or Wheelsmith. Rims? Velocity, DT Swiss...Retro/vintage shiny? VO hubs with Velocity Atlas polished rims.

Hey Abu, a few questions for you:

1. Where did you see that Titanium FSIR? I can't seem find anything on it.
2. What are your plans for components with your 406 FSIR build?
3. What's taking you so long? I want to see the finished beast!

1. In discussions in Bangkok with an FSIR dealer. Plus post #42 shows one. Having said that, i don't think it is for real just yet.

2. 1x drivetrain with 11-42T cogset. This is how it looked before it retired to the storage room. Notice the sprung Brooks Flyer Special, the Ergon GP3 grips, the Kinetix handlebar, and Shimano XT 8000 cogset and shifters & top of the line Avid brakes and levers. It will get folding Schwalbe Marathon Supremes...






3. It's one of three to five builds in the pipeline, plus there's a Dahon Fash Altena waiting in the wings to become my daily, meat & potatoes driver. I won't move in earnest with the FSIR build until I've sold my mainstay 406er, a Dahon Dash. I tend to ride the Dash a bit hard, and it takes the pounding well. I wonder whether the FSIR with its folding handlepost could take the beating just as well, and replace the Dash. The FSIR with its 98cm wheelbase will be livelier than the Dash with its 100cm wheelbase.
