Only using an aero chainring for racing will make it last a lot longer. Change back to a standard ring for training. Simple.
pinkboy In the power never given to me in the name of slowman, king high ruler and Grand Hunky Poo Ba of the blessed land of Slowtwitchia I dub thee "Sir pinkboy the Awsomator" This honor is given to thee for the reason of being not only freakin' awsome but totally sweet. By the use of the color Pink to fly your freak flag and bring smiles to frowny faces. *Mr. Tibbs*
The totaly aero one is pretty pimped - I have seen one on a Clavical crank and it look sweet. I know a few riders who use them on the UK TT seen - waer rate is suppose to be good.
FSA - don't make them them in Campy format any more (at least the Alu aero rings) - I have emailed them as I was after a 54t one for my Ergomo Cranks but the only Campy ones I have found in the UK at a reasonable price have been 55+.
