    Is it harmful to replace the race on an alumimum steerer?

    I am installing a new Ritchey WCS headset on a Lemond Poprad, including replacing the race on the aluminum fork (which has an aluminum steerer). I haven't worked with aluminum steerers before...is there any problem with changing races on an aluminum steerer? I'm asking because I removed the old race carefully and went to install the new one, but the new one slips onto the steerer with minimal effort (all the way to the fork) - it is not tight enough. I'm hoping it's just a problem with the new race, but I'm worried that perhaps the metal on the aluminum steerer was "mashed" to a particular shape by the previous race, and now a new race won't fit properly (?). Is this a concern with aluminum steerers? AFAIK this is the first time the race has been changed on this fork.

    Hammer and flat-tipped punch, working slowly and evenly around the race.

    Did you check the crown race diameter of the old and the new parts? There are two standards out there 26.4mm and 27.0mm.

    +1...
    I'll bet you have the 27 on there and need the 26.4

    It's a 1-1/8" steerer, so there should just be one standard, right? It turns out the problem was with the race (whew). I took the fork to my LBS, they slipped on a couple of other 1-1/8" races, and there was plenty of interference in the fit. The LBS mechanic surmised the Ritchey race slips all the way on because the race is aluminum, but I don't see why that should make any difference. I measured the race ID with my calipers and it was 30mm, as it should be. Weird. Anyway, I found another race that matches the Ritchey race pretty closely and fits the steerer just fine. Thanks for the comments.
