  1. e*thirteen cranks utilize a 30mm aluminum spindle to maximize spindle stiffness
    • 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)

  2. BSA threaded
    • 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
