Bosch Gen 4 ChainringThe Bosch Gen 4 chainring was created taking lessons learned from developing Bosch's SL chainrings. They created a similarly minimal aesthetic but adapted it to be stronger and work with the Bosch CX Gen 4 motors. While being lightweight and beautiful, the 7050 aluminum provides sufficient durability for eBike use, and the new M3 narrow wide tooth profile reduces noise and increases drivetrain durability. Compatible with all 11 and 12 speed drivetrain

Update: sweater looked great when I received. After 1 wash it looks terrible. Looks like it’s been washed too many times, material fuzzy and piled. After wearing it once, it snagged and the knit pulled through. I would NOT recommend. I had such high hopes. Save your money. Very nice sweater, especially for the price! I love the details of the buttons on the sleeves. It is SO soft. It’s not super thick as I can see my skin through it when pressing my hand up against fabric. However, it’s not see through when wearing it. It’ll be perfect in cooler weather and perfect in the winter with a coat but won’t cause me to overheat when in a heated environment. I do feel like it runs big. I could have sized down a size. Although I’m not sure if it’ll shrink after a wash or two.

Disappointed.

Color: Blue, Size: Large, Color: Blue, Size: Large

This sweater is so comfortable and very soft. It fits well in a flattering, oversized way. But after one wash it is pilled everywhere which makes it look old and shabby. It’s at a price point where I feel compelled to return it.

cute but not the material I expected

Size: Small, Color: Pure Black

This was really cute, well made and fit as expected. Unfortunately, I have sensitive skin and I found the material to be scratchy so I sent it back.
