Corona NSB 1x10 Direct Mount Chainring BB30

1e—10 Direct Mount Chainrings for SRAM Cranksets   Lighten. Simplify.   The NSB 1e—10 chainring allows you to remove the spider from your 2e—10 crankset and run a single ring, in tooth sizes previously not available. The chainring is design to give the optimum chainline – in the middle of the cassette. This gives the smoothest shifting across the cassette and the straightest chain when in the largest or smallest cog.   Advantages:   Shave up to 3/4 of a pound off you bike (front shifter, front derailleur, cable and housing).   Over sized teeth for longer wear life – 7% thicker than standard 10 speed teeth.   No chain noise from the front derailleur. (its gone)   Less cluttered handle bar – no more front shifter.   Specifications:   Fits: SRAM S1400, S2200, S2210, X9, X0, XX1 Cranksets   Bottom Bracket Types: BB30 & GXP   Suggested Chain Device: MRP Lopes   Chainline: 48mm from the bottom bracket centre.   Machined from solid 7075 T6 Aluminum   Anodized Black with Laser Etched Graphics   Precision CNC Machined in Whistler, BC   Weight:   GXP   26T- 60 grams   27T – 65 grams 30T – 85 grams 33T – 100 grams   28T – 75 grams 31T – 90 grams 34T – 105 grams   29T – 80 grams 32T – 95 gra
