The STRONGLIGHT CT2 Shimano Dura-Ace 7900 / Ultegra 6700 inner chainring is a high-performance road chainring that is both robust and precise, thanks to its design combining high-precision machined 7075 T6 aluminium and CT² technology, consisting of a ceramic coating impregnated with a layer of Teflon.
The addition of ceramic provides improved hardness, increased longevity and an anti-abrasion effect, while the Teflon reduces the chain's friction coefficient by more than 80%, ensuring reduced noise, friction and lubrication requirements, and optimises indexing between chainrings.
Combining strength, lightness, precision, efficiency and riding comfort, this CT2 chainring is intended for 10-speed Shimano Dura-Ace 7900 / Ultegra 6700 cranksets with a bolt circle diameter (BCD) of 130 mm.

"I bought this product. It was easy to install and looks great on the 7900. I'm very satisfied."
"When paired with a 52-tooth 7075 aluminum chainring, shifting is difficult—it's impossible to shift into 11, 12, or 13 with this 39-tooth chainring; otherwise, the chain tries to jump onto the 52-tooth chainring and derails."
"A very nice product. It meets my expectations. We'll see how it holds up over time."
"a chainring that effectively replaces the original Dura-Ace 7900 chainring"
"The inner rim is lightweight and sturdy, as always with STRONGLIGHT. It seems to me that this is perfect French engineering."
"Replace the 39-tooth chainring with a 38-tooth one on an Ultegra triple crankset."
