For me thats a blessing. 5/8" inch holes mean that this rack is compatible with many accessories from other companies, since unfortunately synergee isnt offering anything other than j cups. Will absolutely buy again. ) Im not going to go into details because there are many reviews already so theres no point in being redundant. And after that long ride, my butt was not feeling all too well. You dont have to remove the face plate to install! dont expect them to be the same. I loved the style of these shoes, really comfy foot bed and a small wedge heel but they were far too narrow. i bought this headphone in 3K. Sony service help desk could not help.
