Using this Shimano Deore FH - M525A rear hub is straightforward. First, make sure your bike is suitable for a QR x 135mm rear axle and a 6 - bolt disc brake system. Install the hub following the standard bike - building procedures. When you're riding, enjoy the smoothness provided by the super - polished bearing races. For maintenance, keep the hub clean. Wipe it down after rides, especially if you've been in muddy or wet conditions.
