Eldron Posted June 1, 2018 Share Dear Hub Wrenching Massif, I have a carbon Niner fork and need to remove the bearing race without scratching the fork. Normally I use tiny screw drivers and work my way onto larger and larger screwdrivers until it's loose. Sometimes this leaves a scratch or two... The Niner fork has no "cutouts" like most other forks so getting the wee screwdrivers in is an issue. How do you do it without scratching it? Give up your secrets!!

paarlmtb Posted June 1, 2018 Share I had to take mine to an engineering shop, but have also seen bearing race removing tools Link to comment Share on other sites More sharing options...
CdT85 Posted June 1, 2018 Share The only way to do it, is the right way. get the right tool or go to your LBS and ask nicely that they remove it Link to comment Share on other sites More sharing options...
Eldron Posted June 1, 2018 Share https://www.parktool.com/blog/repair-help/crown-race-removal-with-the-crp-2-crown-race-puller Oooooh - how have I not seen the Park remover? My Birzman remover doesn't fit - gap is too small and the fork shoulder is too wide. The Park looks like a much better design! Thanks! Link to comment Share on other sites More sharing options...

dasilvarsa Posted June 4, 2018 Share There is a technique using stanley knife blades but it might leave scratches. Hammer in 2 blades on opposite sides and then another on top of it, rinse, repeat. Link to comment Share on other sites More sharing options...

GavS Posted June 4, 2018 Share And my csixx xcm rims... In fact, the carbon melted before the sticker on the rim ???? Link to comment Share on other sites More sharing options...
droo Posted June 4, 2018 Share https://www.parktool.com/blog/repair-help/crown-race-removal-with-the-crp-2-crown-race-puller This thing. It's about a million bucks, but it will do the job. A trip to the LBS will save you a heap of cash on a single use tool on this job. Link to comment Share on other sites More sharing options...
