As the title says,

Will new 11 speed chainrings (the newer ones with the bolts threading into the small ring) fit an older record 10 speed UT crank?

Thanks
Oren


p.s. i did search but found no answer specific to the newer style rings.

Should do. I have older 11 speed cranks with the later rings in 52/36.

Take a quick look through this thread as well.

viewtopic.php?f=3&t=96114

Here is a brief summary...

All 11-speed, 5-arm Campagnolo cranks fall into two groups, 2009-2010 & 2011-2014. For 2009-2010, the inner rings are held by 2-piece chainring nuts and bolts. For 2011-2014, Campagnolo began threading the holes in the inner ring, so only a chainring bolt was required. They also made changes to the 2011-2014 outer chainring that makes them incompatible with the chainring nuts/bolts that were used in 2009-2010. The spider arms, however, are unchanged from 2009-2014.

Note that ultimobici says that he has 2011-2014 chainrings on 2009-2010 11-speed arms, but that you are looking to put the 2011-2014 chainrings on 10-speed Ultra Torque arms. I have no idea if the 10-speed Ultra Torque spider arms changed in design when they transitioned to 11-speed.

yes it will fit. you just need to use the new chainring bolts. the one that threads directly to the small rings

Part Number for the chainring bolts is FC-SR200

Just to complicate things, these comments apply only to Chorus/Record/SR. Not all UT cranks, even of the same year have interchangeability of rings between models.

With Athena carbon UT for instance, Campy used a unique hidden pad height, (higher), so that a Chorus etc outer ring will not work, as I just found out when replacing the rings on my Athena UT crank. The Athena outer ring has a milled recess at the location of the hidden bolt that allows it to sit flat.

In my case it was TA Nerius rings. There's some useful info in this thread http://forums.roadbikereview.com/campagnolo/just-installed-ta-nerius-11-spd-chainrings-343518.html
