Dawes-man: The obvious replacement - MKS Sylvan Touring
Dawes-man: Lyotard 460D - spindle snapped while sprinting uphill
Dawes-man: This isn't the first time - these are from a year or so ago. Lyotard 460D, left & right - spindles snapped at slow speed, both within a week.
Dawes-man: What's left of the spindle - 1975 Peugeot PX60
Dawes-man: All three spindles broke in nearly the same point.
Dawes-man: The snapped ends.
Dawes-man: The 2 upper spindles are from an NOS pair which saw just a couple of weeks of use before snapping. The lower one is older and saw around 150 miles of use by me but unknown previous use.
Dawes-man: Close up of the end of the most recent breakage.
Dawes-man: The graininess suggests to me they were forged rather than machined.

Dawes-man: The spindle on the left is from a new Mikashima Sylvan Touring pedal, on the right is the NOS Lyotard, polished.
Dawes-man: The Mikashima on the left with evidence of having been bead blasted (shot peened) for strength.
Dawes-man: The Mikashima spindle fitted to an NOS Lyotard pedal body. Although the balls measure the same (3.9mm) the Mikashima cone is too thick to allow fitting of the washer and lock-nut.
