If you're like us the back of your car has seen a lot of bikes. Over time this means a lot of grease mud and scratches both to your back seat and your bike. It's harsh on the interior of your car harsh on your drivetrain and harsh on your frame. If part of your routine often includes sliding your bike into the back on the way to or home from a ride consider snagging the SciCon Rear Bike Drivetrain cover to keep both your car and your bike cleaner than before and free of unnecessary scratches and dings for more miles of adventure. The cover is made of out SciCon's AeroFlux Lyra which is durable and smooth so it keeps from snagging on your cassette or rear derailleur and is easy to slide into your car whether the interior is leather or cloth. Slide it on to hold your entire rear wheel drivetrain crankset and front and rear derailleur and protect your chain and seat stays from getting scratched up against a seat belt.
