e*thirteen cranks utilize a 30mm aluminum spindle to maximize spindle stiffness

It is important to note that even though our cranks use a 30mm diameter spindle they are not on the BB30 standard and will not drop in to a BB30 frame. Our cranks use a wider spindle that allows the to fit in a variety of frames and as such they require wider bearings seats than BB30 cranks.

As a result e*thirteen cranks use proprietary bottom brackets in order to accommodate the larger spindle

We offer our BBs in four different common configurations

BSA threaded

PF30

BB30

BB89.5/92/107/121/132 (aka pressfit 41mm)

BSA threaded

Cups are the same between all BBs, but different sizes are offered that include the proper length center tube

Spacers are used to accommodate different BB shells and spindles

PF30

PF30 BBs are for frames with 46mm bores where the BB is designed to press into the frame

Our PF30 BBs thread together in the center for ease of install and to ensure a tight fit

As always, double check with you frame manufacturer to make sure your frame is designed around the PF30 standard

PF30 BBs come with spacers to fit all cranks we make, XCX, TRS and LG1

BB30

BB30 BBs are for frames with 42mm bores where the BB is designed to have the bearings press directly into the frame

Our BB30 BBs thread together in the center for ease of install and to ensure a tight fit

Bearings will sit outside of the BB shell rather than inside in their normal position

As always, double check with you frame manufacturer to make sure your frame is designed around the BB30 standard

BB30 BBs come with spacers to fit all cranks we make, XCX, TRS and LG1

BB 89.5/92 (aka 41mm pressfit)

BB 89.5/92 BBs are for frames with 41mm bores where the BB is designed to press into the frame

In BB89.5 and BB92 the number following "BB" refers to the shell width, spacers are included to fit multiple widths including 89.5mm, 92mm, 107mm, 121mm, 132mm

BB89.5/92 require a bearing press for install

As always, double check with you frame manufacturer to make sure your frame is designed around the BB89.5 or BB92 standard

BB89.5/92 BBs come with spacers to fit all cranks we make, XCX, TRS and LG1
