This is the heavyweight brother of the Syncros Titanium Pro Series bottom bracket.
It has the same beautiful construction, a hollow titanium axle and colour coded gold and black lock rings. But the main difference is that this unit doesn’t have two but three 61903 (6903) SKF sealed cartridge bearings – one on the non-drive side an two on the drive side for superior durability.
Shell: 68mm, 73mm
