##Bontrager Comp Medium Seat Pack The Bontrager Comp Medium Seat Pack is a little larger than your average saddle bag, making it roomy and perfect for ride essentials such as a pump and inner tube. Attach it via the hook and loop straps to keep it secure, and keep items firmly inside with the angled zip - which also makes accessing the necessities a cinch when you're on the go. Fix a light to the loop on the rear of the bag when the sun drops and ensure you're kept safe and seen out on the road.
