Which Lower bearing can be purchased for a Trek Madone 5.9 2012 ,it appears to be a bit of a minefield
I know it's a 1.5 and Cane Creek is a IS 52/40 ,but do I have any other alternatives ?
Many thanks

    IS52/40 is the size code. loads out there.

    IS = integrated
    52 outside diameter in mm
    40 inside diameter in mm

    measurements rounded to closest mm.

    see Parktools for more info on the headset standards.

    what Nick said but to add some bombs to the minefield, some bearings have 45deg inner chamfers and some have 36 degree. If you can get your existing bearing out it may be readable what yours is.
