The Specialites-TA X110 Inner Chainring is compatible with Shimano Ultegra 6800

Does anyone know if it would be compatible with later Shimano Ultegra R8000 crankset ?

I particularly want a 33T ring, which Shimano dont make. I had a 33T on my old bike and I wish I still had it - good for steep climbs I found.

Compatible avec :

105 5800

But see see also SJS - https://www.sjscycles.co.uk/chainrings/ ... nring-33t/

The X110 chainrings are compatible with the Shimano Dura Ace 9000/R9100, Ultegra 6800/R8000 and 105 5800/R7000 11 speed chainsets.

For complete compatibility you must replace both inner and outer with TA rings.

Stronglight also do one 10/11 speed, Spa cycles have them.

thank you
I looked at the TA site but somehow missed the compatibility listing

The TA inner chainrings have the cutout to fit the revised shape of the 8000 series cranks - ergo they fit.
I use TA inners with Shimano outers without problem, BTW.

Thanks all.
Ive now installed my TA 33T inner chain ring.
No problems encountered.
Gear change quality is unaltered despite there is now a difference of 17 teeth between outer and inner chain ring.
