What the AI looks for in Bike Panniers & Rack Trunks
- Hook fit
- Upper hooks must fit your rack tube diameter, and the lower hook must hook into the rack. Loose hooks cause rattle and bags falling off.
- Heel clearance
- Position panniers so your heels do not hit them; check chainstay length. Short bikes or large feet cause heel strike.
- Waterproofing
- Roll-top welded is waterproof; zippered with covers is water-resistant. Wet contents are a common complaint.
- Rack trunk system
- Trunks either strap on or use a matching rack rail system. Proprietary systems require matching racks.
Brands that matter
- Ortlieb: Benchmark waterproof panniers.
- Topeak: Rack trunks and affordable panniers.
- Arkel: Touring and commuting panniers with organization.
- Thule: Pack 'n Pedal panniers.
- Vaude: European panniers with a waterproof range.
What to avoid
- Panniers attached with velcro or bungees only.
- Hooks without adjustable inserts.
Questions
Do I need a rack?
Yes for panniers and most trunks; rackless setups use seat packs and handlebar rolls instead.
