They are freakin awesome. I had a 60/90 set full carbon or a season and they made me much faster. Felt great and I had no complaints about the braking. I’d still have them, but I changed to 90/disc.

I have a set of 30s and a set of 60 rims on Powertap hubs. I'm very happy with them. They're a great value and I'd buy them again.

For a road bike, if you have newer Strikes (62mm?), I'd keep them. I'd sell the original 66mm wheels. For a Tri bike, I'd look at the FLO 60/90 combo or a 60/disk or a 60 set and a disk. I'd also consider the same options in a Hed Jet +.

I have flo 90 front and disc. I've been racing on them for two years and think they are good. Nice looking, reliable, and fast.

I have Flo 60/disc on one bike and a Flo 90 rear on my other.
Mine are Clydesdale (or stallion, whatever they call them), they are stiff and fast and would buy them again if it came down to another wheel need.
The fact they are an amazing value is just icing on the cake.

Ask Hambini... ;)

Seriously, a search would give you around a billion hits on the subject of Flo Wheels. I think most people are very happy.
