BMC Timemachine 01 Disc Headset

The BMC MTT Cover protects the MTT bolt system in the BMC URS gravel bike from the elements while riding, which in many cases can get super dirty, muddy, or wet depending on what kind of rider you are!  The plugs can easily be removed to service the MTT, which is necessary when you start to hear some squeaking coming from the system.  Since the covers are only held in by them providing a tight fit, they can lose some of their holding power over time, which can result in them not working properly or popping out while on a ride.  Thankfully, they can be replaced so you can keep your MTT protected and quite while you're out having a blast on your URS gravel bike!
