a while back i was involved in a post about 3rd gear going out and the feller had a ironman sprocket on the back. i told him that i was experiencing severe drivetrain harshness(along with rapid chain wear) since the install of my ironman,and wondered if that had anything to do with the trannie goin'out? well after removing the ironman i didn't want to go to another hard moly or stainless (would just be the same more than likely) and i really didn't like the thought of going back to steel (too heavy),so i tried a sprocket specialists "titan tough" anodized aluminum. supposed to last 3x longer than the competitors al sprocket. i put it on sun. morn and went for a spin and it was smooth as silk!!! after a 2 hr ride yesterday it shows no wear at all. even if i gotta change it twice as often i know the chains gonna last twice as long. (and yes i realize the stretched chain will wear the 2nd one a little faster) just the fact that i'm not slammin' the trannie any more is satisfaction enough. we will have to see about how long it lasts.
