I should clarify...
When I say that I don't trust them I mean I don't trust them to last. Not because the cranks will fall but because things like weenie chain rings and cassettes wear out way faster. The caad13 is likely going to spend a lot of time on a trainer, which is another reason I'm probably not going to go tubeless even though my carbon rims are tubeless.
The steel disc bike will be what I ride outside primarily. Those tires, as well as the ones on my gravel bike, are already set up tubeless. Which reminds me that I need to deal with them soon since I haven't ridden either of the wheels much over the winter. Ugh. The one draw back of tubeless haha.
