This custom Niner frame bag is sized specifically to fit under the top tube of your 2020 RLT 9 or MCR 9 gravel bike. It bolts directly to the frame via three integrated mounts on the frame - no straps required! Each bag is sized specifically for your frame size and frame material. Use this fitment guide to determine which size bag you need. [2019 and prior RLT frames do not have the frame fitments for these strapless bags] Please note that bag dimensions are made to accommodate the widest range of frame sizes and materials. Photos shown reflect a majority of fitments. Some fitments do not fully fill the front triangle from tube to tube.
