Does anyone know how to straighten (true) a discdrive?

Mine is 2-3mm out (laterally) at one point - if it were a normal wheel it would be a 5 min repair with a spoke key

cheers guys

Is it not the same as a normal wheel but using a screwdriver through the back of the rim on the nipple head?

The SUGINO were trued by tightening or loosening the screws from the inside of the rim. I suppose it´s the same.

go very gently, you'd be surprised as to how much difference one quarter turn can make! Little and often is the key!

be careful

discdrives use kevlar

its very easy to overcompensate a thread in which case its dead
kevler just stretches past its elastic limitandkeepsgoingitsnot like a steel spoke

to pull it back use the offending thread and one either side to true it

there was a specific tool for trueing disc drive, basically a thin blade spanner so that you could adjust in the same way as a normal spoke. (I sold mine to someone on this forum a while back)

Cheers - now straight and true. Used a a very small mechano spanner on the nipple rather than a screwdriver through the back!
