Mezzo D9 advice
Hello,
I’m thinking of purchasing a used Mezzo D9 due to its solid reputation. I’ve heard many good things about its performance and design, which makes it a strong contender.
However, I’ve come across some other threads and comments suggesting that models produced before the 2008 upgrade might have safety concerns due to a design flaw with the forks. I obviously want to make sure that the bike I buy is safe to ride, so I’m looking for advice on how to identify the post-2008 models with the safer forks when browsing through photos on auction sites. Are there any distinctive features that I should look out for?
I’m also curious about the possibility of making the Mezzo D9 lighter through part upgrades. Has anyone here experimented with swapping out original parts for lighter alternatives? What kind of weight reduction is achievable, and what parts would you recommend changing?
Thanks for your help!

Mezzo D9 advice
Hello,
I’m thinking of buying the Mezzo due to its solid reputation. I’ve heard many good things about its performance and design, which makes it a strong contender.
However, I’ve come across some old threads and comments suggesting that models produced before the 2008 upgrade might have safety concerns due to an issue with the forks? I obviously want to make sure that the bike I buy is safe to ride, so I’m looking for advice on how to identify the post-2008 models with the safer forks when browsing through photos on auction sites. Are there any distinctive features that I should look out for?
I’m also curious about the possibility of making the D9 lighter through part upgrades. Has anyone here experimented with swapping out original parts for lighter alternatives? What kind of weight reduction is achievable, and what parts would you recommend changing?
I would greatly appreciate any help.
Thank you.

Just me, but I think the handlepost and stem design is silly, and heavy. Note that the bottom stem projects far forward, then the top stem is tilted back, to put the handlebars almost directly above the top of the fork steer tube. That's the long way around (with more weight) to achieve the same result as a typical bifold (Dahon, Zizzo, et al) handlepost that just goes vertical from the steer tube (direct path) for the same result. Bike Friday uses a long post tilted aft in line with the steer tube, then attaches a typical stem on top to put the handlebars more forward, again, same result. The BF has the advantage to adjust stem reach and can mount a suspension stem, but the further aft handlepost is easier to hit with your knees when climbing standing.
The Mezzo design also makes the handlepost telescoping part parallel with the seatpost, so effective top tube length stays same as both go up. With the typical bifold design like Dahon and Zizzo, the seatpost and handlepost diverge, so as both go up for height, the effective top tube length increases accordingly, proportional to rider height.

#2 if you don't have something good to say, or actually something useful to add to the thread, why comment in the first place? Especially since the OP likes this bike. Is there a recall? Dear lord...

If you think my observations about the design are wrong, you have the podium...

The design is tried and true, and the bike has multiple owners who actually love it. SEARCH THE FOLDING BIKE SECTION AND SEE WHAT ACTUAL OWNERS THINK ABOUT IT. You're not a bike developer, you don't OWN IT, and unless you own one, your opinion is just that, an "opinion". Can you answer the question about the front fork?
Have a great day...

The baseline of the ORI design is to have a single piece frame without the center hinge of the bifold design which is a known weak point of the bifold design.
To reduce the folded length, the frame of the ORI is relatively short (with a single piece frame, the main frame length more or less define the folded length).
One point to check before buying an ORI is if the bike size fits for the cyclist height because ORI doesn't fit well for tall cyclists.

The one-piece monobeam frame is simple and stiff, but due to its short length for compactness, I think that is the rationale of the horizontal stem projecting far forward, then handlepost up and back; I think they need that for knee clearance when climbing out of the saddle, versus a straight vertical handlepost that far back. The very slack head tube angle helps project the front wheel out further to restore some wheelbase lost to the short frame.
