Yes 105 components, although quite old and going out the door due to the fact that well.. they aint needed.

This bike will be my commuter in Hamilton, which is rather flat.

I might try the bio-pace rings, is there a way that I can get the deraileur to work as a tensioner? - Wait that only works with freewheel SS.... haha

Edit - pic served its purpose - thanks for heads up.

The frame is CR-MO.

Yes this is an Avanti Ultra, made by a NZ company probably back in the 80's, or early 90's at best.

Lunigma - did you need any sort of tensioning device at all? SB gives me the thought that I don't need one...

Brendon
