Half way open...

...and completely open.

The seat is firm but surprisingly comfortable for what it is. Looks great and very well made.

Picture is a bit blurry because I must have moved the camera. It's just your typical shimano "RevoShift". We'll see how it holds up over time but it does the job of crisp, accurate shifts.

The Shimano SIS derailleur. This appears to be a newer version. I've had bikes with the entry level SIS and they've all performed well. In fact, I used to own a ReBike semi recumbent years ago equipped with an earlier version of the SIS and held up well to 9500 miles. I replaced it only because I changed my drivetrain setup to use a "Megarange" freewheel which necessitated another derailleur that could handle the 34 tooth "granny".
Thanks for reading.
