I was changing out my fork on my Specialized crosstrail. When taking off the suspension fork, for the new rigid replacement I found that the race on the factory fork is plastic!
Needless to say it slipped right off. I'm used to seeing metal ones that need to be worked off and on. I'm not sure if I want to put it back on. Anybody here ever find this and change it to a metal one? Can I get a metal one from anywhere? Or would I cause more problems with the wear on the bearing. This will just be a road driven bike.
,I know these major companies have gotton cheaper over the years with parts, but geeeez!
What's the matter with the plastic one if it does the job? if you are trying to change it for a metal one, you will probably end up changing the headset, as crown races are specific to a headset designs.
too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
I assume (pardon me if I'm wrong here), that is isn't actually a bearing race, meaning the balls rin on it, but a centering cone that fits to a cartridge bearing. These can be different from the true crown races, you're used to.
Some centering cones are split, and the taper fit to the lower bearing compresses them onto the fork in a way that the split centering cone works on top. Others might be of plastic and sufficiently compressible that they can tighten without needing a split.
Either way the acid test is that it's tight enough when the headset is adjusted that there isn't even a hint of play. If you can't get rid of all the play and the fork makes any noise when bounced, or rocked against the brake, then you need to tighten the fit, or use a bearing retainer to keep it stable.
