Greetings Posted October 15, 2009 Report Share Posted October 15, 2009 How is that possible? Pretty sure they can't fall out unless something is broken. Quote Link to comment Share on other sites More sharing options...
rab shropshire Posted October 15, 2009 Author Report Share Posted October 15, 2009 There was a weird grinding noise coming from the bb so I stripped it down and found that 2 of the bb's were smashed up, and during the stripping a couple of them jumped out and made their escape out of the garage door. you can get a pack of 24 bb's online for a couple of quid so it would be much cheaper than a new bottomn bracket.

cai Posted October 17, 2009 Report Share Posted October 17, 2009 My Echo bottom bracket almost a year old now and its still smooth as ever, no damage on the splines, hasn't bent and makes no dodgy sounds - pretty good for a light bottom bracket.I'm sure it will have a number on the bearing race, then you just order that bearing..

Ali C Posted October 17, 2009 Report Share Posted October 17, 2009 the bearings are odd on those bottom brackets, the inner race is actually the axle itself, they are not your normal cartridge bearings and are not replaceable. Quote Link to comment Share on other sites More sharing options...
