The CycleLocker CS-600 is designed as a stable crank stopper for bicycles. - Brand: CycleLocker - Model Name: CS-600 - Color: Black - Type: Crank Stopper Stand Thank you for viewing. I used this for indoor storage of my fixed-gear bike. I am selling it because I no longer need it. I have used it indoors since I purchased it. I have never taken it outside, so I think it is in good condition. I will disassemble it for shipping. A hex wrench is required for assembly. Thank you.
