Thread Not Engaging
20 Aug 2015
I recently purchased this item from SJS as a spare to take with me on a multiyear trip. Despite persistent but very gentle efforts I can't get the thread of a Shimano BBUN55 Bottom Bracket British to engage. Given the significant cost of this unit and the fact that I'm in Australia I don't want to run the gauntlet and simply order another. I'm absolutely certain that I didn't cross because I'm only using my fingers. Any advice you can offer would be greatly appreciated.
SJS Customer Service:
Hi, take a close look at the threads, you will be able to see if either the Eccentric or bottom bracket threads are damaged. If you think the Eccentric thread is damaged take a photo and email our customer service and they will sort it out. Is it not screwing in on both sides, it would be very unusual to have damaged threads on both sides!
