Frequently Asked Questions
Do I need a hard-shell bag to keep my saddle dry between classes?
Not necessarily. A good waterproof fabric pannier or a seat with an included rain cover will keep your saddle dry for short stops. Hard-shell bags add extra protection for fragile gear and resist deformation, but they’re bulkier and usually cost more.
How do I know a pannier will fit my rear rack?
Check the product’s listed compatible rack width (many state limits like under 6 or 6.3 inches). Also confirm mounting systems (hooks, straps, Velcro) will work with your rack’s shape. If in doubt, measure your rack width before buying.
Are rain covers enough in heavy downpours?
A rain cover provides good short-term protection and is usually sufficient for sudden showers. For extended heavy rain, fully sealed or welded seams and a hard-shell solution offer better long-term protection; also consider internal dry bags for electronics.
