Hi there,
The North Impact from Japan Technology looks very interesting, here are the specs:
Body Material：A6061
Diameter：70.0mm
Width：48.7mm
Weight：73.7g
Axle：M4×10mm
Bearing：C size
Pad：Slim (OD 19mm)
If anyone has one and would like to share their impressions and how it plays, I would be most appreciative.
Thanks!
