It's the little things that really tie together your bike's color scheme, like these Centerlock Rotor Lockrings from Wolf Tooth Components. These lockrings are externally splined t o secure your centerlock rotors to hubs with any axle type: 12mm, 15mm, and 20mm thru axles, as well as quick release. They interface for easy installation and removal with a 16-notch 44mm bottom bracket tool like the Park Tool BBT-9, which you've probably got in your home toolbox. The slim profile and internal splines increase clearance on frames and forks without clearance for a thicker, externally-splined lockring. (Note: These lockrings are 4mm thick and 44mm diameter. This is the industry standard for mountain bikes, and works well with many, but not all road bikes. If you're buying these for a road bike, check to make sure that you have enough clearance first. If not, we recommend Wolf Tooth's thinner Internal Spline Rotor Lockring.) Sold Individually, but you probably want a pair so buy two. Sold Individually. Show more
