Based on this, even with a good rinsing after each use over time the bearings will see significant degradation with repeated pool use. Combine this with more aggressive pedaling and the drive will wear out much faster.
I wouldn't let this scare you out of the pool. For your usage the cost of an infrequent rebuild (it has lasted this long...) may be well worth the pool practice you get in.
Interesting. I wouldn't of thought it would have been susceptible to chlorine because they use plastic pipes for pools and what not but I guess all plastics are not made alike (that's why I'm not a chemical engineer).
I'll stick to self rescue practice in the local lake. [emoji3]
