The packaging is so good that the casing is just 15mm longer, compared with the standard eight-speed auto fitted elsewhere in the 3-series range. When attempting to use a much wider crank spindle than your bottom bracket width, make sure that the bottom bracket bearings fall within the bearing landings on your crank.The BMW 330 e combines the same 2.0-litre, four-cylinder turbo petrol engine that you’ll find in the regular 320i with an electric motor, which is neatly integrated into the eight-speed Steptronic automatic gearbox. Most crank spindles are machined so that bearing landings (22mm, 24mm, 29mm or 30mm diameter) are wide enough and spaced far enough apart to work within a limited range of bottom bracket widths. When determining whether a crank will work with a particular bottom bracket, it is also important to check the bearing landing surface on the crank spindle. In some applications it may be necessary to remove the adjuster. Most adjusters found on 29mm & 30mm dia spindles can be removed to gain additional overall spindle length.
If crank has a pre-load adjuster, measure from the face of the adjuster to the end of the spindle. Remove all crank spacers and wave washer if present.

Road version designed to work in frames shell width from 68mm to 86.5mm. Please see our 24.07 x 37 bearing for use with these cranks.Ĭrank spindle diameter is 30mm from end to end.Ĭrank spindles are 30mm and then have a step-down to 28mm to lock on the non-drive side bearing.
These cranks will not work in normal 24x37 bearings. NOTE: FSA MegaEXO crank spindle diameters can be as large as 24.07mm. Can be used in BB30, PF30, BBRight, 386EVO frames with the appropriate length spindle.ĭesigned to work in frames shell width from 68mm to 86.5mm.ĭesigned to work in frames shell width from 68mm to 92mm. 3-piece crankset with separate, replaceable spindle.

Uses wave washer on drive side of crankset to take up any play in crank. The crank slides completely through a 24x37 drive side bearing and stops against a 22x37 non drive side bearing. Spindle diameter is 24mm on the drive side, and 22mm on the non-drive side where the splines are.
