Desperately need some advice. My A race is on Saturday (560km ultra endurance one day). I was using my race wheel set with carbon-ti hubs during last month training preparations. They are pretty new with just 1000km on them. Last Saturday during a ride a knocking/grinding sound was coming from front wheel and finally narrowed it down to bearings problem.
My mechanic managed to quickly swap out new bearings set and wheel looks good.
I do have my other training wheel set with DT Swiss 240 hubs and they have been bomb proof with over 8000km.
I would still like to use my new wheels but worried I don’t have time to ride and make sure the bearing replacement is ok.
Given the length of the race, I’m in doubt. Should I be using known training wheel set or fixed one? Any thoughts?
