Loose collars on bumper plates January 13, 2021 by ufantast1c_f0x I purchased two rogue bumper plates for a cheaper price then new (also still sold out) but the collars are loose. Has anyone had any success fixing these? If so how? Thank you! submitted by /u/fantast1c_f0x [link] [comments] SOURCE: Fitness Time with Friends – Read entire story here.
