There is no data when Shimano FH-RM70 Front Hub is released, but some anectodal evidence points back to late 2000’s or early 2010’s.
Machine marks on aluminium body is a tell-tale sign of a entry-level item, but this is a very well sealed, well made and quite lightweight hub. Under 150 grams, it puts many higher level front hubs to shame. I bought this brand new at a very good price, less than 10$ few months ago.
This front hub is not disc brake compatible. It’s Acera level, out of series, but still expect some Shimano quality.
As all Shimano hubs, this has a cup and cone design, too.
