Danny Kearns Posted April 10, 2008 Report Share Posted April 10, 2008 Hey guys, Just got my Echo External BB off a friend in the post. Only problem is the cups on the BB wont pull off, Ive even hit it with a hammer it wont move, the wierd thing is, he was using the BB before he sent it me Any idea's ?

psycholist Posted April 11, 2008 Report Share Posted April 11, 2008 You only need to take one cup off to fit the BB. If there's no flange on one side of the bb, thread the BB in to the frame at that side with the rest of the BB hanging out of the frame and you'll have a bit more leverage to pull the cup off. Stick up a photo in case people have specific issues with that type - if what you're describing as an external bearing BB is of the same style as Hollowtech II/X-Type/Whatever Truvative call theirs, this solution won't work, but this system usually only has a plastic tube joining the bearings on each side of the frame.

AdamAllen Posted April 12, 2008 Report Share Posted April 12, 2008 (edited) Open a vice so its just bigger than the threads, rest the cup on it. Then whack the axle. Edited April 12, 2008 by econtrol Quote Link to comment Share on other sites More sharing options...
