Ok I've read some older posts and checked around for tools etc. For the most part in old threads (from several forums) I'm getting that a spoke torque wrench is only needed if you were installing ALL new spokes and needed a base to work from before further tuning it (after truing). Also (if the above be the case) then all a bike owner needs to check and or tighten spokes (tune them by sound), would be a spoke wrench ( just the wrench) that fits the spoke. Please confirm your experinces on this. Additionally my Street Bob spokes appear on rough measurement to be 6.1 to 6.3 mm, does anyone know the exact size of my spoke nuts ?
