What I thought was creaking from the need of new bearings turned out to be a crack in the rear Flo 30. I have not had an accident on these wheels. Still, I've been riding my entire adult life & have ridden equipment to the ground. Never have I experienced something as "catastrophic" as this. The irony is that I always considered the 30's to be the most bomb-proof wheelset I have ever ridden. (I'm passed the warranty stage.) The issue is this: I ordered those 30's along w/a set of 60's alu/carbon. So, I assume they came from the same production batch. If you were me, would you now abandon the 60's for fear of aluminum cracking?

I really loved those 30's. Always thought them far more reliable than the newer Aeolus on my roadie. :(

I wouldn’t be the least bit worried about your 60’s. I have a set and they are indeed bomb proof. I’d be worried about your busted Flo 30. What did you hit? Obviously, there are always potholes, railroad tracks and road debris that can damage a wheel. Did you follow proper inflation on their bar graph? I just don’t understand how a wheel develops a stress crack without some type of acute stress on the wheel.

Thanks for your comment. I'm in DC & used them primarily for work commutes, i.e., dedicated smooth bike path. Again, zero accidents. And yeah, followed proper inflation on EVERY ride. Who knows... I'm so first-world-problem depressed. And I've been fixing to purchase a set of their full carbon wheelset

Exxxvii: Thanks for you comments as well. Haven't heard back from Flo. Doubt they can do anything. :(

This is a type of situation where a picture speaks volumes. Also, +1 for not thinking twice about riding your 60's. FWIW, I've had 30's, 3x 60's, 90's, and 2x discs starting from round 2 with zero issue aside from needing truing.

If you could send us a message on our contact page, or write me privately here, I can help you out.

Have a great day,

Yep this is the main reason why I also bought FLO wheels (because of Slowtwitch)...

Yeah, I don't know any other company where I can email the owners and ask any number of questions and get a response in an hour.

Yep me too.
