HOW TO MOUNT OVAL CHAINRING TO SHIMANO 12SPD HYPERGLIDE+ CRANK: Using Hollowtech II BB Removal Tool (like BBB BTL-116 ), carefully open the lockring that holds the chainring on the crank(normal threads). Once the lockring is removed, take off old chainring, re-grease the splines on the crank. Place new oval chainring with convex side to the crank. Chainring/crank has special splines that only fit one way. Close the lockring to 35-50Nm of force. Chainring is only compatible with CN-M9100, M8100, M7100 & M6100 Shimano 12spd Hyperglide+ chains. Using other chains may cause chain to drop very easily from the chainring due to thinner than usual teeth. ✔ #originalbrand #readystock #100%new #genuine #authentic ✔ Delivered from Selangor ✔ Parcel delivery is arranged within 1-3 working days ✔ We are #ecocana a SSM registered company ✔ Retail/Repair/Showroom at Ecocana Sports, Gamuda Gardens Waterfront Village, Rawang Can buy from our official website: https://ecocanasports.com/absolute-black-oval-shimano-direct-mount-chainring?search=absolute Shopee: https://bit.ly/3nPsTjw Lazada: https://bit.ly/3q3ScRt Or direct to our physical shop at: Lg02, Waterfront Village, Gamuda Gardens, 48050 Rawang, Selangor Note: There will be cheaper price if buy in our physical outlet bundle with other items.
