THM Ceramic Road External BB Cups - BSA-68-30 / ITA-70-30

THM use high-grade steel rings with ceramic balls which are treated according to a special greasing and sealing procedure. The main benefit is less an extreme smoothness in operation than a longer service life and reduced maintenance. Due to the special properties of steel and ceramics this combination is however not suited to withstand severe shockloads, so THM offers these bearings for Clavicula Road and Road M³ only.

Available for ITA and BSA bb shells.

Material: bearing cups: aluminium | bearings: stainless steel, ceramic
