Miche Integral Road RD Bb386 Shimano bottom bracket

If the frame is the skeleton of the bicycle, the bottom bracket is its heart

The first Press-Fit bottom bracket with adjustable cups and CeramicSpeed bearings. If the frame is the skeleton of the bicycle, the bottom bracket is its heart. The bottom bracket as an organ capable of receiving and distributing the cyclist's force. Force that becomes driving force and finally speed. Integrale RD is the latest addition to the Race Division product range. High performance without compromise.
Ceramic bearings produced by CeramicSpeed aim to reduce friction, increase watts, go faster. The reduction bushings produced using filled epoxy resins facilitate assembly and prevent the ingress of external agents, protecting the bearings.
Integrale RD is a Press-Fit 86.5x41 (BB86) mm bottom bracket dedicated to cranksets with 24 mm axle diameter. The two anodised and adjustable AL 7075 T6 aluminium alloy cups are assembled by means of special threads.
Press-Fit is the standard preferred by discerning cyclists. Pressure caps save several grams on the final weight of a bicycle, increasing smoothness and final performance. The adjustable cups give the component a longer life and increase the rigidity of the structure, while limiting the incidence of all those variations that in the long term can lead to defects.
