Input:
Question: Can you flip the hold-down all way back (extending the length of the rack)?
Document: Works great as long as the seat is high enough otherwise you cant lift the spring loaded hold down all the way up.
I was looking for a rack that was fixed (vice detachable) that had no connection to the rear axle. This fit the bill nicely. I took my time adjusting the shims during install and the result is a rock solid seatpost connection that I'm positive will hold maximum weight capacity. I chose the spring hold down to mainly hold a ballcap when I ride with my helmet and it works out great.
Excellent rack, solved problem on how to mount a rack on a bike with rear suspension that I use for city commuting.
May take some fitting effort, but shims provided give adequate fit capability for tight fit on seat post. The spring loaded hold-down is handy for light loads, but could interfere with an underseat carry bag if you have one.
Answer: yes
