weirdoku Posted October 11, 2014 Report Share Posted October 11, 2014 Okay. Before I send these back and make myself seem like a tit I need to confirm it's not me that's wrong (or right, depends). Got these self extracting crank bolts off eBay. They come with 2 bolts, 2 washers and 2 retaining rings. I put the Echo TR cranks on, screwed the bolts and washers in. Perfect. But then when it came to the retaining rings they wouldn't go in, had a closer look and noticed the threads are reversed. I assumed the rings screw in (clockwise) the same as my crank extractor. Looked at my crank extractor tool and the threads match the crank threads. When I thought about it, it makes sense that the retaining ring threads should be reversed so that when you unscrew the crank bolts the ring doesn't unscrew with it. But I have NEVER come across crank arms with reverse threads, Google says cranks with reverse extraction threads exists though. So what the heck have I got? Or am I retarded and ordered something that wasn't right for my cranks?? Quote Link to comment Share on other sites More sharing options...
isitafox Posted October 11, 2014 Report Share Posted October 11, 2014 Sounds wrong to me, I'd send them back and ask for a refund or a new set of retaining rings with the correct thread Quote Link to comment Share on other sites More sharing options...

james webster Posted October 11, 2014 Report Share Posted October 11, 2014 I have had an old set of 24/7 bmx cranks that had reverse threads. But no other cranks i have had. So don't knows if any other cranks have had them. Or just them. Quote Link to comment Share on other sites More sharing options...
weirdoku Posted October 11, 2014 Author Report Share Posted October 11, 2014 I swear from just googling self extracting crank bolts I can see the 99.99999999% of the retaining rings don't have reverse threads... Waiting for a message back from the seller and see what he says. Quote Link to comment Share on other sites More sharing options...
