Designed for modern MTB frames with 89.5mm or 92mm shell widths, it reduces rotational friction and trims weight compared with older GXP-style setups. The result is a durable, low-maintenance bottom bracket that keeps power transfer efficient across varied trail conditions.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this bottom bracket protect bearings on muddy or wet rides?\u003c\/h3\u003e\n\u003cp\u003eThe DUB PressFit uses improved sealing around the cartridge bearings to keep contaminants out and lubricant in, extending service intervals. Its design channels water and grime away from bearing races so the internals experience less wear.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eGutter-style seal design to divert debris\u003c\/li\u003e\n  \u003cli\u003eFully enclosed cartridge bearings for simplified maintenance\u003c\/li\u003e\n  \u003cli\u003eDurable materials suited for off-road exposure\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this work with my frame and crankset?\u003c\/h3\u003e\n\u003cp\u003eThis unit fits frames with a 41mm shell inner diameter and accepts BB89.5 or BB92 press-fit shell widths.
