Crankset for my pinarralo Dogma 60,1 Moviestar 2011

Sorendk

Hi All

I have a Pinarello Dogma 60,1 moviestar from 2011.
On this I have Dura Ace 7900 10speed (I am pretty sure it is with a long a arm-shifter on the back), with a pedal arm of 175mm.
I would like to have a crankset with a smaller arm 170 or 172,5 mm and maybe go compact or semi compact, but I can't remember what size of bottom bracket I have (It says BB-7900 on it).
What crankset is possible to mount on to my bike and is it possible to have 11 speed?.

I hope some of you can help me.

Best regard
Soren

An 11speed crankset will work fine with 10spd 7900...you just need to decide if you want a 50/34 or 52/36 and what length cranks you require. There are plenty available used on eBay. There is no need to change the BB, the 7900 BB will work fine with 5800/6800/9000 cranksets.
