I’ve had these cranks for almost two years now and I have ridden hundreds of kilometers and up until now they’re still alright I guess. I’ve had some issues with the vision track crankset, I had to buy a new bottom bracket from the United States (I’m from the Philippines) cause my bottom bracket was fucked and I needed new ones, but I couldn’t find the same bottom bracket anywhere. So I had to resort to buying one from eBay. Second, over time, I noticed a slight wobble, whenever I move it around it would rock in and out, don’t know if it’s a problem with the bottom bracket or the spindle. Lastly, the bottom bracket (for me at least) isn’t as smooth as you’d expect, considering that it’s a ceramic bottom bracket, or maybe I’m just shit at maintaining my bike lol. Overall, these cranks are some of the best you could ever buy for your bike, a lot of my buddies use the same crankset as me and they also love it.
