The Osprey Syncro is a nice pack. The hydration system is excellent. No leaking! There are a few things that I would change. The main pocket on the front is just big enough to hold a couple of bars and maybe a multi-tool but not big enough for bars, tool, tube and your phone. I would sacrifice .5L of water for a little more storage especially since 2L of water is more than adequate for most rides. I would also nix the waist belt. The belt is overkill when you already have shoulder straps and a chest strap to hold the pack in place. When you are hunched over a bike the belt is uncomfortable. At the very least it should be removable. I plan to cut the belt off of mine. The frame that keeps the pack off of your back is a very nice feature. I also like the magnet on the bite valve that keeps it on the chest strap for easy access.
