Does anyone know what the normal cost would be to extend the threads on a steer tube? I feel like I was ***** without a kiss.
Do you mean that they threaded the steerer below where the threads went previously? If so, and the steer tube was not chromed, they robbed you blind as it takes all of 5 minutes, max. If it is a chromed steerer, you should pay the cost of a new cutter as the chrome will destroy cutters and then $50 is OK. If they added extra length then $50 was cheap..
