XLAB

I like the XLAB top-tube bags. They are lightweight, aerodynamic, and provide easy access. No more stopping, getting off my bike, unzipping my under-the-saddle bag, rooting around and hoping nothing falls out. I got the Stealth Pocket 100 for my race day bike. I tried the Stealth Pocket 400c for my training bikes but found it too narrow to hold my training day needs. I returned it and got the Rocket Pocket XL. It has room to hold my emergency tire stuff, my flip phone, hydration packs, with room to spare! And it sits below the top of my headsets for good aerodynamics!

I have only used this bottle cage a couple of times but it seems to hold my bottles pretty securely.

My bike frame is size Small and I use a 20 or 24 oz bottle so having the side release is helpful.

I bought the Stealth Pocket for my top tube to use in addition to a larger seat post back that holds my spare tube and other repair items. I use the Stealth Pocket for more frequently used items such as gels, chews, tablets, etc. that I can even access while riding or quickly grab during a brief stop. The bag is narrow which is aerodynamic but that does limit its capacity so you have to make some tradeoffs in what and how many items you can pack.

I can't believe how much stuff I can cram into this bag! I'm an ultra cyclist and often need to carry 1000's of calories with me to fuel my rides. Seriously, this thing is like Mary Poppins carpet bag, I can keep stuffing things in to it and it stays nice and slim and aero. Easy to open. Occasionally a little hard to zip closed because I've got it stuffed so full. Great product!
