RCG Racing Tracer / MT-One ボールベアリング (6.35x9.53x3.17mm) (8個)

These bearings dropped straight into the MT-One without any fiddling, and the 8-piece count is perfect for a full set. My wheels spin noticeably smoother now, so I'm grabbing another pack for the Tracer as a spare.

The 6.35x9.53x3.17mm sizing was exactly right for my FTX Tracer's wheel hubs, no shims needed. They spin smoothly and the price for eight is fair, considering how often I replace these.

The 8 bearings arrived quickly and dropped straight into my FTX Tracer with zero fuss, so the compatibility claim is spot on. They spin smooth and quiet compared to the stock ones I replaced, which wore out way too fast. A solid, cheap fix for anyone running this chassis.
