Truvativ 5D cranks

These came on my Apollo Synchro 26 tandem.

Weight of drive side crank arm is 283g.

The crank arm is a consistent width and thickness and remains perpendicular to the bottom bracket spindle for a distance that means you could shorten these down to perhaps 130mm.

Update

I got a second hand set of 175mm FiveD cranks and shortened them to 150mm. The design of this crank makes it particularly suited to such shortening. Worked out well.


Shortened FiveD crank

Further update

I can confirm that it is certainly possible to shorten these cranks down to 130mm .  They work well and the end result is really nice.
