Evening all. In my shop days the spokes that failed the most often were on the right side of the rear wheel. These spokes did the most work because they had to both support there share of the combined weight of the rider an d bike, and transmit the power from the rear hub to the road. Often when a costumer brought us a rear wheel with a broken right side spook, and if th e hub and rim wear in good shape, I would advise them to replace all the ri ght side spokes, rather than make 15 more trips to the bike shop as they br oke one at a time.

The other trick was if a costumer brought us a wheel with a cracker, (or un loved tubular) rim, and we had a new rim with then same inside diameter and number of spoke holes, we would zip tie the two together, and then more th e spokes over one at a time, and them true the wheel. It saved time if all the parts matched up. If not, new spokes.

Most of the customers saw our reasoning, and wear grateful to have trouble free wheels when they left the shop.

I hope everyone gets the holiday bicycle wishes filled.
