Note: 63801 and 3801 are same dimension, but internally the 3801 is dual row and the 63801 is single row.  The 63801 (this one) is what is fitted OE on Canyon Frame Pivots.  You can use 3801H7 MAX if this one out of stock.

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

This is the 'BO' version which is Black Oxide - a corrosion resistant treatment.
