Beginners Guide to riding Fixed/Single Speed in London

If a backpack for cycling is only going to have one sternum strap then higher is better. This means that when you lean forward on the bike and your arms and shoulders move inwards, it's the sternum strap keeping the main straps away from your shoulder joint/arms rather than your shoulder joint/arms themselves stopping the straps sliding off.

But every bagmaker has their own theory on design...so long as you're happy and comfortable, that's good enough for me. ;)

Seems to work well, but then I dont think the bag is designed for heavy loads, more of trail riding bag.

What I really want is one of these.
