Dual Row version of 63801 Max
Inner x Outer x Depth (mm): 12 x 21 x 7
Used On: Canyon Frames

Note: 3801 and 63801 are same dimension, but internally the 3801 is dual row and the 63801 is single row.  The 3801 (this one) is slightly stronger.  Canyon specify 63801 on their frame, but you can use this if either 63801 Max out of stock or if you want a slightly stronger bearing.

Be Careful: Trek use a very similar bearing (3801 MAX) but it varies in depth - the Trek version is 8mm depth.
