Who has a spoke threader?
 

I'd ask this on the mechanics forum, but I don't know anyone there, and figure you folks are very DIY oriented. I picked up a 2004 Fuji Rouaix Pro for cheap, since it needed a new rim. It is my first non-C&V bike and I'm finding it strange and exotic. It has a Mavic 24 spoke rear hub that uses straight pull spokes. I have a replacement rim, but it has a smaller ERD - about 13mm smaller. I have now discovered that Mavic straight pull spokes are rather expensive to obtain (over $2 a spoke!). I'd like to simply trim the current spokes, but they will need about 5mm more threads. Where can I get this done? Does anyone here have a spoke threader? I'll check at the co-op tomorrow, but I thought I'd ask here first. Thanks all,
