PRAXIS - E-BIKE STEEL WAVE 1X 104BCD 

Designed specifically for e-Bikes and longer wear, Praxis steel e-Rings are cold forged from 4130 high-grade steel with a nice black oxide finish. Licensed and developed in conjunction with Mountain Racing Products, the Wave™ pattern tooth profile applies alternating lateral force to each chain link to actively retain the chain to the ring – going beyond narrow/wide implementations that rely solely on friction, while allowing room for mud, debris, and grit to escape. The Wave™ design also wears more slowly than competing designs by spreading the load over larger surface areas. 

  • Steel e-Ring for e-Bikes 104 BCD | 32 - 36T 
  • These e-rings are "female" threaded. Male M8 CR bolt threads into ring for motor clearance. 
  • Wave™ Tech tooth profile   
  • 10/11/12sp Shimano/KMC/SRAM 
  • Cold forged 4130 grade steel 
  • Black Oxide coating 
  • Rear Der - Must use a "clutch" type rear derailleur. Example Shimano Shadow or SRAM Type 2 
  • In very rough terrain, or just for pure security, use of an upper guide is still recommended

They make your cards look super professional.
Size: 40 Cards Display Case Standard, Size: 40 Cards Display Case Standard
I am moving into my new house soon and over the last month I have purchased 5 of these. They make your cards look super professional. I think I have all that I need but if I ever another one, i would buy this one or I would say that I highly recommend this one, and this is coming from the guy who usually never leaves a review for anything but these are awesome.

Lots of defects in construction
Size: 40 Cards Display Case Standard
I bought two of these, and at the time of writing this review, currently I've only loaded one with graded cards. First thing, the appearance looks decent, though some minor cosmetic issues here and there on the wood. After I got the display mounted on the wall, I started putting in the graded cards I wanted to display, and at first everything was going well; until I got to the 4 row. I noticed the first card I placed was wobbly, and would lean to the right. I looked at the card case, and figured it must be the case itself, until I put in the 3rd & 4th cards, and they to were wobbly, I ran my finger where the card sit and noticed either chipped wood, or excess glue, which prevent the cards from sitting flush against the rail. I continued to insert more cards, and one the bottom row, I noticed right away that there was a spacing issue between the 4th and 5th rows, and that the board between the two rows is bowed downward. I put a level on it and verified... which absolutely is is bowed. NOT COOL! Let's see how the return process goes now...

Buy if you collect cards and want to display
Size: 40 Cards Display Case Standard
Arrived as pictured. Very nice display case for baseball cards or whichever types of cards collected. Gifted to husband who collects baseball cards. Hold quite a bit of cards. Mounted on wall just fine. Glass is clear and we put a light strip on the inside, which added to it. Bought two of these.
