BWW Pure XCR MTB Hub Set 450g


These XCR’s are light weight, with strong engagement.  The biggest negative is that they are Shimano HG and QR/QR only.


The BWW Pure XCR’s were a great edition to our product line up when we first brought them.  They were light weight, solid, and with 36 POE, better than a lot of other hubs at the time.  But as axle standards/spacings have expanded, and as cassette/freehub types have expanded, we decided to Not redesign the XCR.  Instead, we opted to move to the Pure D400, but that’s another conversation.  Needless to say, we’ve built a lot of XCR wheel sets over the years with this hub set, and they’ve held up extremely well.
