Here is a review and more information: https://www.bicycle-guider.com/giant-contend-review/
This bike has the following modifications:
- Front stem riser to raise the handle bars. This part is easily removable if you would like to lower the handle bars back to the original position.
- Brake levers added to the horizontal part of the handle bars. The original drop handle bar brake levers are still there also and work as they always did.
- Kick stand
- Rack
- Regular pedals. Original clip pedals available if you want to put them back on.
The frame size would probably work well for someone around 5’6” - 5’9”.
