Hi ladies and gentlemans,I would like to ask if anyone in here that had encountered these problems.My used wheelset which is bought months ago had been facing the same problem which is the flat spoke turning 45 degrees away from its original position after few rides which is causing the wheels starting to go out of true.I knew the tools which is used for truing the wheels.But when I ma tuning the nipples,the flat spokes doesnt go back to its original place.Is the problem of the spokes or the nipples??Can any of you please share some information regarding to this.Thx
