Few more data points on crank weights..

Crank weights in the ETK are for sets including bearing shells, these shells weigh 0.460 kg for both S14 & M10.

Bare cranks

M10 crank = 37.57 lb

M10 hub = 1.1 lb (stamped pulley)

S14 crank = 43.96 lb

S14 hub = 5.3 lb (damper)

S14 sport E3 crank = 38.67 lb (11 21 1 316 978)

The lightest cranks for M10 were the early 71 mm stroke 1600 that had only four balance weights (versus eight weights on the later).
