Selling a Dura-Ace 7800 crankset, crankarm length is 172.5 and the rings are standard 53-39. The set has only about 600 miles on it.
I built up my new tri bike this spring when I was living in Washington DC but shortly after relocated to Massachusetts. After the move, I decide to switch to compact cranks since Mass is a bit more hilly than DC was.
No bottom bracket included, just the crankarms and the rings. $150 shipped in the U.S.
