Cycling training has gotten complicated with all the different methods and technologies flying around. As someone with extensive cycling experience, I learned everything there is to know about this topic. Today, I will share it all with you.

The Saddle Bag Situation

Spent way too long researching saddle bags before my first century ride. Needed something to carry a tube, multi-tool, phone, and snacks without bouncing around. What I learned: not all saddle bags are created equal, and the right choice depends on how you ride.

The Main Categories

Bicycle saddle bags attach under your seat. Range from tiny tool pouches to larger bags that can hold rain gear. Most road and gravel riders use these.

Frame bags and top tube bags are alternatives for bigger loads. Not technically saddle bags but worth mentioning since they’re part of the bike-packing decision.

Handlebar and seat post bags exist for bike-packing setups when you need more than a saddle bag can hold.

Materials Matter

Nylon: Lightweight, usually waterproof or water-resistant. Most common for cycling bags. My Topeak has survived four years of rain and road spray without leaking.

Leather: Classic look, genuinely durable. Heavier and requires some maintenance. Brooks makes beautiful leather options that look better with age.

Canvas: Sturdy and affordable. Some riders like the aesthetic. Not as weatherproof as synthetics.

Features Worth Caring About

Capacity: Determine what you actually carry. For a tube, CO2, and levers, a small bag works. For longer rides with food and an extra layer, you need more space.

Waterproofing: Roll-top closures stay drier than zippers. If you ride in rain regularly, this matters. My zippered bag eventually started letting moisture in.

Mount system: Quick-release beats straps for frequent removal. Some bags attach to saddle rails, others to seat posts. Check compatibility with your setup.

Stability: A swaying bag is annoying. Look for designs that stay put during out-of-saddle efforts and rough roads.

Reflective elements: Visibility matters, especially if rides sometimes extend into dusk. Most quality bags include some reflective hits.

Brands That Consistently Deliver

Ortlieb: Waterproof is their thing. German engineering, roll-top closures, built to last. My buddy has had his for eight years of year-round commuting.

Topeak: Good value, practical designs, reliable zippers. The Aero Wedge series is popular for a reason.

Brooks England: Premium leather options with old-school craftsmanship. Expensive but ages beautifully.

Lezyne: Clean designs, reasonable prices, good functionality. Their Caddy series works well.

Apidura: Great for bike-packing. Larger capacity options when you need to carry more than basic tools.

Keeping Them Functional

Wipe them down after muddy rides. Dirt accelerates wear on zippers and fabric.

Re-apply waterproofing spray annually if your bag isn’t fully waterproof by design. Check for worn spots where the bag contacts the saddle.

Store bags dry. Zippers corrode if you leave a wet bag packed away. Air them out after rainy rides.

Inspect mounting hardware periodically. Straps fray, clips wear out. Catching problems early prevents mid-ride bag ejections.

Sizing Guide

Small (0.5-1L): Tube, levers, mini-tool, maybe a gel or two. Fine for supported rides or short loops.

Medium (1-2L): Above plus phone, ID, cash, extra snacks. What most riders need for unsupported rides up to 60 miles or so.

Large (2L+): Rain jacket, arm warmers, full tool kit, substantial food. For centuries, bike-packing, or multi-condition rides.

Installation Notes

Follow manufacturer instructions. Incorrect mounting causes bags to bounce or fall off.

Distribute weight evenly — heavy items toward the saddle rather than swinging at the back.

Tighten straps securely but don’t over-tension. Straps under constant high tension fail faster.

Test the setup with a short ride before any serious distance. Problems reveal themselves in the first few miles.

Where to Buy

Local bike shops let you see and handle options before buying. Worth the trip if you’re unsure about size or fit.

Online retailers have broader selection. Check return policies since saddle bag fit can be finicky with some saddle and post combinations.

Whatever you choose, get something that fits what you actually carry and mounts securely to your specific bike. The best saddle bag is the one you don’t notice during rides.
