Looks like i have sorted it, took a couple of mm off the lockring overall length, it now tightens onto the frame

Hi I have just brought my first bike a 2nd hand Echo pure but the bottom bracket lockrings keep coming loose. it looks as if when both lockrings are tight the one side (o ring side) is not tight on the frame as you can rotate the o ring, but bottomed out on the spindle? there is a spacer on the other side (sprocket side) Do I just need a thicker spacer to allow the lock ring to tighten on the frame or am I just doing it all wrong? Any help or ideas would the good

I ride Moto trials and subscribre to Trial Magazine, After reading several bits in the magazine and tests of cycle trials bike, I decided to buy myself a Second hand Echo and have a go myself and am loving it even though its so frustrating at the moment, The Tarty bike articles (Servicing a bike and the shop feature) then led me to buying some bits and pieces off them but forgot to use the code at the time. So all your efforts havent gone to waste as I am now enjoying learning to ride a "pushbike" again and will defenitely use Tartys again, and will probably be upgrading some bits as I get better. Cheers Rob
