In general I like them. It seems like Vision only forge one length of crank arms and just drill the pedal holes at different spot for either 165 or 170 so the 165 arms look strange compared to 165 Dura-Ace. The chainring bolts are the spinning type that are annoying to deal with. Haven't received yet the Dura-Ace knurled chainring bolts but I see no reason why they wouldn't work.

I used the FSA steel BSA bottom bracket but any BSA bottom bracket made for 30mm axle will work. Plenty of options available if I want to upgrade later to a ceramic bottom bracket.

Installation was super easy but then again square axle is also easy to install. For maintenance, you can keep the FSA BSA bottom bracket cup in place and just extract the cartridge bearing and replace them compared to replacing the whole bottom bracket for a square axle or octalink crankset. The Vision crank comes with a auto-extractor bolt so removal is also very easy.

The Vision crank arms are bigger in all dimensions compared to Dura-Ace but have the back-side hollowed out. Just need to wait for summer or a chance to go to Milton to try out their stiffness.

Regarding the TK FRD frameset, I was pretty happy to see that it came within the box 2x bayonet top crown and 2x splined knuckle so the only thing I was missing to have two complete setup (1 for TT and 1 for drop bars) is another 31.8 stem faceplate. Had to go with the shortest extension to be within the 75cm rule for TT bars and I can run the longest extension and still be inside the 5cm limit with a compact 36cm road bar. Just need to see if my back muscles can handle to go that long and low with the drop bars. Daily stretching could be useful.
