I've done 2.000-2.200 km on the wheels now. 1.200 in danish winter conditions, with rain and cold weather, and around 800 km in the mountains of Alicante, Spain. And I think its time for an update.
As mentioned at some point earlier, I rebuild the wheels with Miche Primato Syntesi hubs bought at bm0p700f's shop - the cycle clinic. Really reasonably priced and with a 24r/20f option. I didn't want to bring out the DT 240's in the danish crapweather, which is why I switched for more affordable and more durable hubs. I guess though this will put the wheels in the heavy category with around 1.800-1.900 grams (just guessing). But who cares about weight when everything is about aero now, right
The rims and hubs have withstood both the danish crapweather, and riding mountains in spain.
In the danish crapweather it doesn't really make a big difference, what kind of wheels you run under your prolonged mudguards. Aero benefits from wheels when riding mudguards is not really relevant. But the wide profile still makes a huge difference while cornering with or without mudguards.
The Flo's are 25.92 mm wide and the inner width is also significant. For my trip to Spain I mounted 23 mm GP4000s 2 conti's and they measured 25.4 mm. Descending in the mountains was absolutely superior with these wheels. They feel very good en crosswinds as well.
I must say that they have become my do-it-all training wheels.
My friend rode the Zipp 101 wheels on the same trip. The Flo rims are only 40 grams heavier each than the Zipp 101, but almost 2 mm wider, and the shape of the rim is way more toroidal than the Zipp 101, which make the Flo's more desirable than the Zipps IMO (not to mention way more affordable).
As mentioned earlier, the only drawback is mounting and dismounting tires. Didn't matter if I ran Schwalbe Durano + or the GP4000s 2. They both where very difficult to dis(mount).
The ParkTools TL-6 tirelevers do a great job though. You just have to watch out not to pinch the tubes while mounting the tire with the ParkTool levers.
If you don't mind a little more hazzle when dis(mounting) tires, you really get great alloy clincher rims with the Flo30's. They really do the job, and they look very nice as well. I just hope, that Flo will work on the brake track size - maybe shave of 1 or 2 mm to make tire handling easier.
