HANDLE
- 07/11/13
- 8" of prestretch: works OK, no problems with bungee system, but still chain slippage on handle sprocket
WHEEL
- 07/11/13
- red-green, yellow-purple, white-blue bungees in parallel
- total bungee length is 21.75"
- too much pre-tension; the erg comes to a jerking halt during the boward recovery
