luke2405 Posted May 12, 2010 Report Share Posted May 12, 2010 Hi, Have been using some echo sl cnc cranks and a try all bottom bracket. I have always torqued these up after every 10 or so rides and used thread lock so they never were able to become loose. Have been riding them for around 6 months or so. Was riding today and felt my pedals wobbling a little got off to check and found that I could easily move the crank from side to side with my hand a couple of mm. took the crank off and found the bb where the cranks sits a little bit crushed. Am I going to have to fork out for new cranks and bb or is there anything I can do ? Thank you Luke Quote Link to comment Share on other sites More sharing options...

AlexxRogers Posted May 12, 2010 Report Share Posted May 12, 2010 Sounds like you need a spacer between your crank and the end of your BB, because there is too much BB spline for the crank. Alex. Quote Link to comment Share on other sites More sharing options...

davey1991 Posted May 13, 2010 Report Share Posted May 13, 2010 No thats to space your free wheel away from your bashplate. You need a BB axle spacer, something similar to... this, http://www.chainreactioncycles.com/Models.aspx?PartnerID=79&ModelID=34981 Quote Link to comment Share on other sites More sharing options...

ISIS cranks have a 1 degree taper, so moving it outboard along the axle will make the crank fit LESS tightly, therefore round off even more quickly.
