For sale, Shimano Dura Ace 10speed chain rings, 54/39. used these about 10 times on my TT bike before converting to QRings. They are in excellent condition. if you get them, dont think so, package them right back up and send back and i’ll credit the purchase price.
its a 54/39, which is THE setup for the dura ace cranks. Shimano does not recommend this setup; the stock setup they offer is usually 53/39. but we’ve been running this on most of our riders SRM and non-SRM dura ace cranks. they work great. i run this ring setup on my TT bikes and my road bikes. Using the 54 lets you have a big gear for descending or TT"ing, and yet you still get a nice 39 for climbing. sometimes if you cross index (which you shouldnt do anyway) like a 39front x 11 rear, you get some rubbing due to the size of the big ring. but its minimal and anyone with some experience should know you dont run a 39x11 other than for a moment if you slip up on shifting.
this lets u use 1 crank for TT’ing, climbing, everything. you get the best of the 54 biggie, without giving up the climbing.
if you mount and think it doesnt work right, again, send it back.
i use these on all/ALL my cranks, and many of our team riders. shifting is as good, no issues.
