Review on 🛼 Twincam Ilq-9 Pro Rollerblade Bearings by Bob Fasho

They were expensive so I had high expectations. But after about 2 months of driving about twice a week the bearings started to slow down. There is also vibration at some of the bearings where I could feel and hear the obvious "lump" when riding in quiet places. I don't think abec9's rating matters much and in the future you won't spend double the money to buy it instead of abec7. Next comes either ceramic or abec7.
