Requires a separate ISIS bottom bracket and 4-bolt 104mm BCD chainring. Verify bottom bracket shell width and threading (typically Euro or English standard) before purchasing a bottom bracket. Ideal for riders building or upgrading a drivetrain who want forged aluminum cranks with the ISIS interface. The 4-bolt 104mm BCD chainring mount is a common standard with good chainring availability. ISIS cranks provide a stronger interface than square taper but are heavier than modern splined or integrated spindle systems.\u003c\/p\u003e \u003cdiv\u003e\u003cp.\u003e\u003ci\u003e\u003cu\u003e\u003cfont size=\"2\"\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/font\u003e\u003c\/u\u003e\u003c\/i\u003e\u003c\/p.\u003e\u003c\/div\u003e\u003cdiv style=\"\"\u003e\u003ci style=\"font-size: 0.875rem;\"\u003e\u003cu\u003e\u003cfont size=\"3\"\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/font\u003e\u003c\/u\u003e\u003c\/i\u003e\u003c\/div\u003e\u003cdiv style=\"\"\u003e\u003ci style=\"font-size: 0.875rem;\"\u003e\u003cu\u003e\u003cfont size=\"3\"\u003e\u003cb\u003e**Due to unique nature of this item, ALL sales of this product are FINAL.
