E-bikes add to the riding experience by simply providing more for less. More distance, more laps, more climbs and more descents. With all those “mores” also comes more weight continually bashing on the components of an e-bike. In order to overcome the increased forces induced by the technological progression of modern e-bikes, WTB designed the HTZ rims with more material in every area of the rim profile. Every wall of the rim is 25-30% thicker in comparison to those of standard rims, which are then paired with the proven I-Beam center support to ensure no beating was too great for these rims. All HTZ rims are TCS 2.0 tubeless, feature asymmetrical spoke drilling, and are available in widths ranging from i23 to i35 in order to provide options for e-bikes ranging from e-assist gravel bikes to dual-crown downhill bikes that no longer need a truck to be shuttled.- Capable of withstanding the forces of a modern e-bike
- 4D angled spoke drilling eliminates binding and lateral loading, and disperses tension more evenly over a greater area
- Symmetric outer profile provides equal dissipation of impact forces on both sides of the rim while asymmetric spoke hole drilling allows for more even spoke tension and increased wheel strength
- Disc-brake only
- TCS 2.0 Tubeless ready and comes with a preinstalled Solid Strip, which lies beneath the tubeless tape and prevents sagging at the spoke holes, creating a smooth interface between the rim and tire bead. This prevents air from escaping around the bead and therefore requires less air volume and pressure to mount a tire. Solid Strip also protects the airtight tubeless system from being punctured in the case of a broken spoke.TCS 2.0 creates a more robust, easily installed and dependable tubeless system

It's perfect support.
Size: Extra Back Support (21-Inch), Color: Dark Grey
The best way to describe the super comfy reading pillow is super comfy. I use it to sit up while watching something soothing to my mind on tv and due to its comfyness and softness, it's perfectly just right for my back. The funny thing is within a few minutes I'm knocked out sleep, which is a good thing. It's soft but firm lumbar area and arms feels oh so comfortable. It gives the best sleep quality and less toss and turning. I highly recommend.

Great Size and Comfort
Size: Extra Back Support (21-Inch), Color: Dark Grey
2 months after buying a different reading pillow I felt it was time to buy a different one based on the comfort and support. I found this one listed for a good price. After carefully looking through the listing, I bought the 21" size. On my first night of usage, I was already impressed with the comfort and support vs the reading pillow I had bought 2 months prior. I like how this one has nice support for my neck and head as I'm relaxing on my bed with my laptop and phone. The texture of the filling gives it a very nice combination of cushioning and firmness. The horizontal feature line in the center of the pillow is a nice feature for back and neck support thanks to it giving the pillow some flexibility. As for the arms, their length, width, height, and cushioning are very good for resting my arm while I'm using the wireless mouse with my laptop.

Book Reading Wife Approved
Size: Standard (18-Inch), Color: Sage Green
I purchased this for my wife who reads quite a bit and she absolutely loves it. She said it feels soft, is the right size for her, and makes book reading more comfortable for her. I call it a win.
