Been biking since 1999 and have had two previous MB's and what I do as a routine is clean the chain; drivetrains (FD & RD); and disc brakes after each day of riding and also look over the chain rings for any damage that could have happened on a ride. I give the bike a good look over as to the frame to make sure there has been no damage and relube the chain and check the front shock as well for any obvious glitches.

Other than that you may want to pay attention to your cables for the first 100 miles. New they tend to stretch til broken in and may need adjustments. If your not comfortable doing this find an experienced rider with mech. skills or take it to your lbs for them to look it over.

They are pretty robust machines!

Also if you have hydraulic disc brakes you may want to make sure there is fluid with no leaks evident; mech. disc brakes are lower upkeep to me.

Enjoy and ride it like you stole it!
