The Praxis Works Shimano Hollowtech II bottom bracket converter is designed to be a proper bottom bracket BB for installing Shimano Hollowtech II cranks in either BB30, PF30, or Specialized’s OSBB road frames. Our patent pending design keeps the cartridge bearings outboard of the frame right on Shimano spec for greater rigidity and free of frame/c-clip tolerance issues that other conversion bb systems deal with.

Simply press in the longer non-drive-cup, then the shorter drive cup threads into it. As the drive cup threads in, our trademark Collet system expands to a precise limit evenly dispersing pressure for a super tight fit. With both cups connected and our collet set exactly to spec, there is no chance the bearings can come out of alignment or wiggle/walk out of the frame. This bb converter design also uses a compressible o-ring on the non-drive side cup to compensate for frame shell width discrepancies.

Worth it! Solid dermaplaner.
Color: Matte Blue
It feels solid in my hand. The blade doesn't seem to be all too sharp, but it works... so maybe that's for safety purposes? I like it and will stick with it for a while.

Hair removal improvements, ooooh! Ahhhhh!
Color: Matte Gold
We were vexed and a little annoyed by that one chin hair removal after a waxing treatment. Lo and behold! Zomchi invented a razor for treatments in between salon wax strips. Painless and easy to reapply hygenically. 🤗

Handy. I've never put a razor to my face, but I used this and loved the outcome.

Great moisturizer
I tried this after demaplaning and it worked great. I have decided to not keep up with dermaplaning so I now use this after shaving my legs to moisturize them. It works great for post shave moisturizing on the legs and face.
