Avant Garde just released a teaser for the next 1 piece cast style they are bringing in, the M640!
Excited for the release of these, concavity looks deep, and its definitely something different I havent seen in a cast wheel yet
First release will be brought in in 20"+ sizes only
It looks to me like its pretty much a cast version of their F340 forged monoblocks!
More info to come as it becomes available!
