Hi. Someone sold me a SRAM Rival 1 rear derailleur and the B Bolt is seized inside the RD. As first I thought it was seized to the mech hanger so I sawed that away, but it's fully seized. Have tried penetrating oil + hammer + allen key. Going to drill it out tonight.
In theory it should be an easy job once it's out. According to SRAM you just need part 11.7518.060.000 (SRAM Rival1 B Bolt and Limit Screw Kit). However, I cannot for the life of me find out where to get this. These guys seem to sell but it's not in the list. These guys have a lot but not that specific part number.
Question: Could I use a different SRAM B Bolt set for this? Or do they have very specific lengths? Are any of them interchangeable? Would like to salvage this RD.
