I needed a high rise crown race because the adjustment knobs on the fork I purchased with my new bike would hit the downtube when the wheel was turned too far. Fortunately this solved the problem. The crown race arrived via mail, however, with a chip at the top. I contacted MRP customer service who was very responsive, and offered an exchange. He assured me that the chip was too small and too high up to affect function and I already had an appointment at the shop to install it, so I went ahead and used it and it works with no problem. So kudos for a part that solved my problem and good customer service but deduction for the damage that I think happened before it was shipped (seemed well packaged and no chip seen in the package.
Works as advertised!
