T.A. Specialites Zephyr 110 BCD Outer Chainrings

Comments:

I am still having front derailleur adjustment issues with the outer 48 tooth ring. I discovered that opposite the chain stop pin the ring was warped 2 1/2 - 3mm. Since I experienced this problem since it was new I caution those that purchase TA Zephyr chain rings to check lateral run out with a dial gauge or by lying on a flat piece of glass. I am disappointed with this TA product. They have a good reputation and for the price they should be straight with in at least 1/2 mm. My inner 36 tooth TA chain ring is fine.

If you have a pre-proprietary chain ring Campy 110 mm alloy crankset these are a drop in replacement. Smooth shifting and they run true. You may want to remove the shift pins depending on the inner ring you chose. I am using 48-36 with no problems after 3 years. I did remove the shift pins from the inner ring as they are not needed on a double setup. I am using Campy Centaur derailleurs with a 7 sp. freewheel on a 130 mm rear hub. Sensitive to Front derailleur set up with the Campy Centaur but once you have it all works great.

This is a great ring to use for cranks with a 100bcd, for juniors in order to enable them to meet "Roll Out" (gearing restriction). When paird with a cassette that as a 12 as the smallest ring, it meets roll out perfectly. Our Juniors team uses it for CX and road. Super high quality and compatible with a good range of cranks! We have experienced a little bit of problem when using it with SRAM. Not sure if it is the Front deraileur or the shifter that is casusing it not to work well.

Does not have shift assist pins as advertised.
