This is my first aluminum profile rig and I love it. Extremely sturdy and the black looks great. The pieces were easy to organize and all the parts were separated in their own little bags. I also really like how there are extras as well. Shipping was quick too.
If you use the photos in the Google Drive link as a reference, it's quite easy to put together. It took about 3 hours to build, and then spent a few more hours throughout next few days adjusting different pedal, wheel and seat heights to find something that worked for me. I also added some castor wheels so it moves around easily, and it's not nearly as heavy as I thought it would be.
Overall, very happy with this purchase!
