cyccommute would have a better idea of what to recommend.
Titanium rates as “fair” in terms of resistance to around 20% sodium hypochlorite solutions. Carbon fiber is about the same. Epoxy rates as “poor”. Household bleach is only 5 to 6% sodium hypochlorite so it likely won’t have much effect on any of these materials. That said, there is little reason to use it on bicycles.

Is this going to harm the bike?
You need to ask “to what purpose?” Covid-19 isn’t just hanging around outside waiting for us to open our doors. If the bike has been outside, away from people for more 24 to 72 hours, it can’t have any virus on it. The virus just doesn’t survive that long outside of a host. Most of us aren’t in the habit of parking our bikes where people can handle them, sneeze on them, or cough on them.
