Hi. I'm an experienced cyclist but encountered a situation today that I need advice on. I purchased a new Cannondale CAADX 105 bike back in May of 2020. I have ridden about 3500 miles on it so far. Roughly one month after I purchased the bike, a spoke broke and had to be replaced. Roughly 3 months after that, a 2nd spoke broke and was replaced. Roughly 2 months after that, a 3rd spoke broke and had to be replaced. I have not had any other spokes break since then (thankfully). Yesterday I was on a ride and my rear tire started losing air. The tires are road tires, which is all I've ever ridden on, but apparently they can also be ridden on gravel, which I have never attempted. The tires are also tubeless. I dropped my bike off at the bike repair shop yesterday for the tire to be repaired (no punctures were found... just a leaking valve stem and some sealant which was replaced). I picked the bike up today, but when I did so, I noticed that my rear wheel now needs to be trued. Needless to say, I dropped it back off to the bike shop today for that to be done. When I dropped the bike back off today, the mechanic on duty told me that I may want to consider purchasing a new tire rim, because 3 of the spokes had been replaced in the past and the mechanic indicated that if any more spokes have to be replaced, then I won't have any choice but to purchase a new rim. Is this an accurate statement or is the bike mechanic just trying to have me purchase a rim for no reason? I've had the same bike shop perform all of my repairs and maintenance, but this is my first time dealing with this particular mechanic (he's new to the bike shop). Any advice is greatly appreciated. Thank you.
