Jena is the carbon gravel bike, designed to give you the greatest freedom of choice for your rides. Whether you're looking for pure performance on gravel roads and singletrack, or adventure, exploration, and bikepacking, Jena is designed to meet your every need.

Racing comfort geometry
The Jena 60TON monocoque carbon frame is made in 5 sizes (from XS to XL) with geometries that allow for a high level of comfort, without sacrificing responsiveness and performance that comes close to that of Wilier's competition bikes.
The slacker head tube angle ensures ride quality and stability even on the most challenging terrain. The rear end, on the other hand, has been designed to have a marked response to vertical stress, absorbing much of the vibrations generated by uneven terrain.

Usability
Jena places no limits on usability and available configurations. The clearance between the frame/fork and wheels allows you to install generous tires on 28" wheels or 650B MTB wheels. With 28" wheels you can install tires up to 44 mm wide, while with 650B MTB wheels you can go up to 48 mm wide, equal to 1.95" (tested on a Vittoria tire).
Numerous mounts are available to allow you to install bottle cages, bags, racks, or fenders. For example, the front fork can accommodate two water bottles or a lowrider rack for bags.

Kamm tail design
An aerodynamic down tube was developed on the Jena, giving it the classic truncated tail shape typical of Wilier's aerodynamic frames.
Removable derailleur mount
The derailleur mount can be removed for single-chainring groupsets, a drivetrain that's now very popular among gravel enthusiasts. You can choose between a double or single crankset at any time, without compromising the bike's look.

Nice divider, serves it's purpose well!
Size: 3 Panel 12FT W
This room divider worked out very well for what I needed. I wanted a simple way to create a little more privacy and separation in a larger room without doing anything permanent, and this divider was an easy solution. The panels provide good coverage, and the black color gives it a clean, modern appearance that blends in nicely with different décor styles.
Assembly was fairly straightforward, and once set up, the wider feet helped keep the divider stable on the floor. I was especially happy with how flexible the panels are to arrange. You can keep it mostly straight, angle it around furniture, or create a more enclosed private space depending on the layout you need.
The material allows light to filter through slightly while still offering a noticeable sense of privacy. I’ve used it for separating a workspace area, but it would also work well in bedrooms, apartments, dorms, studios, or shared living spaces. Another plus is that it can be folded and moved without too much effort when you want to change the setup.
Overall, this divider delivers a good balance of functionality, portability, and appearance. It’s a practical option for anyone needing temporary room separation without installing permanent walls or curtains.

Perfect for Adding Privacy to a Piano Studio
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
I Ordered the 2 Panel version which is way too big for my needs... that's on me. So keep in mind that the picture shows a fabric made for two panels only being used on one and hence it is not pulled tight; it would pull tight and not be so wrinkly if it was set up properly as two panels. The metal pools that make up the panels seem to be well made, stable, and of good quality. They were very easy to put together and they stand up tall with plenty of height. The appearance of it with the fabric on it isn't as elegant as it could be, but it still looks good enough. The material is plenty solid, not allowing light through it, and thereby making a solid barrier. I am using it to block the view out the studio door when a student is sitting at the piano to avoid distractions from the hallway. It will allow a student to enter the studio with our distracting the student who is at the piano.

Room Divider That Gives Instant “This Is a Separate Space Now” Energy
Size: 3 Panel 12FT W
The Siebwin 3 Panel Folding Privacy Screen is surprisingly effective at changing the feel of a room without requiring construction, commitment, or somebody yelling about load bearing walls. The 12 foot width gives a substantial amount of coverage, making it useful for creating privacy, dividing open areas, blocking visual clutter, or setting up temporary sections within larger rooms. This saved us a ton of time and money in our new studio and enabled us to create a kitchen and office in one room.
The wider feet make a huge difference because flimsy room dividers that collapse every time someone exhales too aggressively are deeply annoying. This one feels more stable and grounded once positioned. The folding design makes it easy to move around or adjust depending on the space, and it folds down relatively compactly when not in use. It is basically the introvert curtain wall of dreams.
The material has a clean, neutral look that blends well into different room styles without screaming “temporary office cubicle panic.” It works well for apartments, studios, shared spaces, dressing areas, or simply hiding the mountain of chaos you swear you are going to organize tomorrow. Practical, portable, and refreshingly easy to use without turning setup into a three hour emotional event.

It's 2 panels holding 1 big privacy screen. Can't use as 2 separate 4' panels, but works great.
Size: 2 Panel 8FT W
This 2 panel privacy screen works well. Assembly was very straight forward, with easily labeled tubes. My son and I had it together in about 10 minutes, which was probably 3 minutes of me telling him to quit playing around and hand me the parts. It feels very sturdy, not likely to fall over or anything. The material fits well, with the Velcro being very strong. Measurements are all very accurate, with all pieces attaching properly. We have a similar privacy screen at work that we have to try and stretch out because the top and bottom Velcro doesn't fit quite right... this model does not have any issues though. The material is thin and light weight, but solid black so that you can't see anything through or behind it. I definitely think it's a great deal for the money.
What I think would have given it 5 stars though, is if you had 2 totally separate 4' panels instead of 2 panels with one big screen. It really wouldn't cost any extra to make it so that the screen was in 2 pieces and you could use it as 2 separate panels instead of having to use it as one big panel. It says 2 panel folding privacy screens, but it's really one big one that folds in the middle.

Perfect Privacy Screen
This room divider is exactly what I needed. Assembly was a breeze, and the wheels make it easy to reposition. The anti-peeping material provides great privacy for video calls. It feels sturdy and looks modern. A simple, effective solution to create a quiet workspace.
