Shimano Dura Ace 9000 chainset. 

Crank arm length is 170mm. Chainring sizes are 50 and 34. A compact setup ideal for mountain climbing. 

This has been on my summer bike and has seen very little use. I'd guess the mileage is about a maximum of 200. 

There's a tiny amount of shoe rub as can be seen in the pictures but it's only very small and doesn't detract from the chainset. 

Cheapest I can see in the usual online sources is £334.99 for the compact so grab yourself a genuine bargain. 

The only reason I'm selling it is because I've bought a Stages Ultegra 6800 and I want to match it up. 

Thanks for looking and if you have any questions please contact me.
