Once? Was that because your friends intervened before bad things happened? BTW, I hesitate to ask
this but what is "snek?"

One set of friends (rowing) would have been very enthousiastic. Another (cycling) would have
laughed, at best. But no, it did not seem like something I would spend much time doing so it was a
bit expensive to buy just for dust collecting.

"Snail" in English. Mechanical device found in clocks.

From rowingbike.comsnek efficienter dan ketting2.htmOpen ↗ For a few years now the rowingbike
uses a cable-snail transmission in stead of a chain-chainring transmission. The snail, a system
already used in clocks a few centuries ago, has been rediscovered by Derk Thijs who implemented the
system in his rowingbike. The snail is a conically shaped aluminium box with a winding groove where
a 3 mm wide stainless steel drive cable can roll up and down. This steel cable has been wound 1.5
times around the snail. On the drive it rolls down and on the recover it rolls up again. The cable
turns the snail by friction and thereby drives the wheel. (my translation).

The page describes how the snail transmission is more efficient than the chain transmission (on the
rowingbike).
