Instant trunk
Topeak Backloader. Oversized under-theseat bag that allows you to carry lots of gear without a rear rack. Why we like it: Racks can break under the stress of mountain biking and can’t be used with dual-suspension bikes. This giant streamlined bag mounts easily, cinches tight so it won’t sway and has a waterproof inner liner. Info: $74.95 for 6L size and $84.95 for 10L, topeak.com
