This is Shimano's take in the front mech adapter that's sold as the specific adapter for the R9100 front mech. I believe that this one is an updated version, it has a bit of a recess where a washer would fit, on the front. I looked at pictures of the same part number and they looked a tiny bit different, probably no difference in performance. This came in the newer grey card box (as opposed to the older blue boxes) so I presume it's more recent. The clamp bolt threads directly into the aluminium, there's no nut inserted at the rear so maybe a bit more care when tightening required. Nice, black anodised finish.

Ottimo prodotto come qualita , stile e pesoConsigliato
