Martin Reynolds Posted May 6, 2011 Report Share Posted May 6, 2011 (edited) Basically after killing my trialtech bb in a week im looking for advice :/ Im running adamant cranks, and the Tarty boys said that becasue they are cnc rarther than forged, they are weaker and my cranks might be worn on the splines (even though the cranks are a few months old), therefore pulling onto the bb axle too far, butting against the trialtech stop washers and creating too much side load on the bearings. Are the cranks ment to touch the stop washers? On my old onza bb/cranks, the crank splines locked out on the bb axle, and everything was hunky dory Edited May 6, 2011 by Martin Reynolds Quote Link to comment Share on other sites More sharing options...
eskimo Posted May 7, 2011 Report Share Posted May 7, 2011 butting against the trialtech stop washers and creating too much side load on the bearings. Are the cranks ment to touch the stop washers? On my old onza bb/cranks, the crank splines locked out on the bb axle, and everything was hunky dory Dunno about that first bit. You sure they said that? Maybe you misunderstood something? The cranks should go all the way onto the splines. The axle or crank is tapered for a tight secure fit. Every time you remove and reinstall and arm it'll wear slightly each time. Dunno about that washer, but it may just be there to suit all crank styles, whether they can over hang onto the axle? If you ain't running FFW. Try a shorter bb and better bb if you can. There's plenty out there! Quote Link to comment Share on other sites More sharing options...

Im sure they said that forged cranks are stronger and that my cranks could be worn. Im not 100% about the spacers part, but thats what i interperated/could figure out. I always thought they were tapered and locked out on each other. Could i get away without using the washers? What's their purpose? Adam? Ali? Mark? If you ain't running FFW. Try a shorter bb and better bb if you can. There's plenty out there! The trialtech bb is ment to be a bloody good one, never heard a bad review. I think me killing it is down to bad install/faulty product. Im running ffw, but i wouldnt go with a shorter axel, i prefer a wider stance.
