I bought an FSA Wing Pro handlebar and I would like to know if I can use cross levers with it. I don't know as I don't have the bars yet (bought it off eBay) and I was wondering about the "wing" part of the bars.
After seeing that the levers are 31.8 and the bar is 31.8, I realizing that the levers will fit near the stem and decided to get a pair. I hope I like it that way, but seeing as I have never used these type of levers before, I am not trying to redo something I have gotten used to.
The problem you might encounter, other than the cable bend, is that your hand placement will be very close to the stem when using those levers. This will make handling/control very twitchy and unstable, which is the opposite of what most people are trying to achieve when using cross top levers.
