DESIGN OF THE GEARBOX TYPES

Common to all gearboxes is the spur gearing consisting of two sub-units connected in sequence. The individual gear ratios are derived by matching the two sub-units with various cog pairings. The P1.18 gearbox is built using a 6-gear unit mated to a 3-gear unit – a 6 x 3 gearing type. The P1.12 gearbox is a 4 x 3 type.

Gearing optimized for touring use, from trekking to MTB. With a 600 % gear range, the P1.12 transmission far exceeds the performance of a comparable derailleur.

18 gears are used exclusively in our flagship P1.18. The unmatched overall gear range with equally spaced gear steps is the reference for bike touring and bikepacking.

A Lifesaver for Peace and Quiet in a Noisy Apartment
Size: 48" X 10', Color: Grey, Number of Items: 1, Size: 48" X 10', Color: Grey, Number of Items: 1
Living with a very loud senior with hearing issues can be quite challenging, but this soundproofing room divider has been a game changer! The panel, crafted with acoustic foam and felt, significantly reduces noise, creating a peaceful and private environment in my home. It's perfect for setting up in my study room or bedroom, allowing me to focus without distractions. This divider isn't just for noise reduction; it also serves as a handy display board. I can easily use thumbtacks and hook-and-loop fasteners on its felt surface for presentations or home education purposes. The versatility makes it ideal for office meetings and visual displays too. The package includes a foldable privacy panel, two curved support stands, a fastening strap, and non-slip tape. Measuring 48" X 6' when open, it folds down to a compact 48" x 15", providing flexible layout options. Assembly is a breeze—just attach the curved legs, and it's ready to go! I appreciate that the divider is lightweight and portable, making it easy to move around. The design is safe, with no sharp edges, and includes anti-slip tape and stable stands to ensure it stays in place. Overall, this soundproofing divider has truly improved my living situation, and I highly recommend it to anyone needing some peace and quiet in a noisy environment!

Expensive, But Genuinely Effective and Worth It
Size: 48" X 6', Color: Grey, Number of Items: 1
Because I need to work from home, I converted a corner of my living room into my workspace but was constantly distracted by the sound of the TV and family activities. Although this partition wall is expensive, its effectiveness genuinely surprised me. It doesn't create complete silence, but it is incredibly effective at absorbing and dampening background noise. Now when I'm in a video conference, the sounds from the other side of the room barely come through. The entire partition is made of solid materials, is very stable when unfolded, and the grey felt surface also looks high-quality.

Decent at dampening sound
Color: Grey, Color: Grey
This partition was easy to assemble and is stable. My husband and I both work from home, and the desire was to have a sound barrier. It definitely dampens the noise. If it was another foot taller, that would be even better at dampening the noise. Obviously, we still hear one another quite well, but the partition simply softens the noise of each other.
