- Model: Power Disc I
- Color: RED ANODIZED
- Weight: 114g
- Material: 6061 aluminum alloy
- Chainring interface: 110 bcd / 130 bcd (Don't know what size Bolt Circle Diameter your existing chainring is? Measure center-to-center of two adjacent bolt holes on your crank spider and then refer to this chart: http://www.sheldonbrown.com/cribsheet-bcd.html )
- Crank spindle size: 23.75mm (for one piece cranks) - if you want to run this on a 3-piece crank, you will need an adapter (the system allows you to choose the correct adapter when you select this product). Keep in mind, crank spindles can be 19mm, 20mm and 22mm - so be sure you measure your spindle to be sure you get the correct adapter. Due to the thickness of this power disc, only our "A" adapter for 19mm spindle will work with it.

NOTE: The smallest chainring that will work on this power disc is 38T.
