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

A decent oil pan but would benefit from being larger
This oil pan works decently but would be much better if it were slightly larger. At the size it is it is easy to miss the pan and make a mess. The pan holds enough oil for a bike or lawnmower but not enough for a car or truck. The plugs screw on well and don’t leak from my use. But the pan has inner lips that hold oil and make it hard to clean, would be much better if it were a smooth surface. The pan is made of thick plastic though and is well built overall, it just could be designed better.

Too small to avoid spilling/splashing!
Returning it as this was way smaller than expected!

Low profile
Worked perfectly for draining oil from zero turn lawnmower. Even cons with a spare inlet plug
