Frame-Pack
Ortlieb
The Ortlieb Frame-Pack is an expedition-ready piece of equipment tailored for cyclists confronting atrocious weather. Built around Ortlieb's signature welded fabric technology and an industrial-grade waterproof zipper, this pack creates a truly impervious shelter for gear inside the frame triangle. Whether traversing swollen creek crossings or pushing through all-day torrential downpours, contents remain bone-dry. The pack uses robust PS21R fabric, a polyurethane-coated nylon that shrugs off grit, mud, and frame rub without fraying. Strong, interchangeable Velcro straps wrap around the top tube, seat tube, and down tube, securing the pack firmly even on aggressive mountain bike terrain. Because the internal layout maintains a slim cross-section, knee clearance remains consistent regardless of how tightly packed the central compartment is. However, absolute waterproofing comes with mechanical realities. The heavy-duty waterproof zipper has significant friction compared to standard coil zippers and requires periodic lubrication with silicone paste to maintain smooth operation. Additionally, the rigid mounting structure and specific angular profile mean it fits standard hardtail and gravel frames cleanly, but full-suspension bikes with complex shock linkages may lack the interior clearance necessary to mount this pack properly. **Highlights** - IP67 waterproof rating with high-grade waterproof zipper - Welded PS21R nylon construction eliminates stitched seam leakage - Slim internal profile prevents knee rub during hard pedaling - Adjustable, heavy-duty Velcro straps secure tightly to various tube diameters - Exceptional resistance to mud, grit, and high-pressure spray **Watch-outs** - High-resistance zipper requires regular silicone maintenance - Inflexible angular geometry does not fit many full-suspension bikes - Premium price point compared to standard non-waterproof bags

Ultimate Six Plus
Ortlieb
The Ortlieb Ultimate Six Plus is an iconic, quick-release handlebar bag designed primarily for touring riders, commuters, and long-distance road travelers. Unlike soft bikepacking rolls that lash to the bars with straps, the Ultimate Six Plus locks into a rigid, bar-mounted bracket. This setup delivers rapid one-handed detachment at stops, turning the bag into a secure shoulder pack for carrying valuables, cameras, and documents off the bike. Constructed from waterproof, PVC-free Cordura-blend fabric with welded seams, the bag offers complete protection against persistent downpours. A magnetic lid closure snaps shut easily and stays latched over rough asphalt and gravel paths. Inside, a rigid internal frame maintains the bag's structural integrity, stopping it from collapsing or resting against the front wheel. The top lid on modern iterations features a transparent, waterproof compartment designed specifically for smartphones or paper maps. The main drawback of the Ultimate Six Plus is its rigid mounting system. The mounting block claims permanent handlebar space and is incompatible with many aero bars, closely spaced computer mounts, and aggressive drop-bar configurations. Additionally, the overall system weight is noticeable on the steering axis, which can make unloaded front ends feel slightly sluggish on quick gravel descents. **Highlights** - Fully waterproof construction with IP54 rating and welded seams - Quick-release mounting bracket permits instant removal at stops - Magnetic lid closure seals smoothly with one hand - Transparent touchscreen-friendly lid compartment for phones or maps - Rigid internal structure prevents sagging regardless of load **Watch-outs** - Mounting bracket requires permanent clamp space near the stem - Substantial baseline weight of 20.1 oz for the 7L size - Rigid geometry makes it poorly suited for rough, technical singletrack
