Hambone Designs sent me a black leather, Top Tube Velo-Pocket, and it's way rad. It's basically an envelope more or less. It's got two straps for the top tube and one more that attaches to the down tube. Then a large flap that folds over the top tube and snaps the whole thing shut. It's a really great idea that works really well.
Hambone makes them in all flavors including animal friendly materials. Personally, I like my rock to roll until it crumbles apart and my leather real...and black, so I was stoked to get this in the mail- just my style! I've been using it to keep a couple wrenches, a small Crank Bros. pump and multi-tool, and a pack of Topeak's Fly Paper. Can't forget the tire levers either- pretty much everything to fix a flat if needed, along with anything else that I don't want in my pockets...keeping them bulk-free while I ride.
The Velo-Pocket's are big enough to hold all the essentials without getting too bulky itself, yet small enough to take with you when it's time to lock up- quickly and easily. In use, it keeps it's slim figure, and stays in it's place. No thigh/leg rubbing or swinging around where it doesn't belong. Outside Dimensions: 10.5" wide x 6.25" tall, Inside Dimensions: 9.5" wide x 6" tall, Top Tube Straps: leather – 3.5" long, fabric – 4.5" long, and due to the handmade nature of their bags, actual size may vary.
Hand Made here in the US and assembled with fat rivets and big snaps, this looks like it's going to last a long time- and being leather, it can take a spill (which hopefully doesn't happen again any time soon! (knock on wood!)) and instead of shredding will just slide with everything else- and like everything else, it'll get back up and be ready for what's next. There's a reason why people who ride motorcycles wear leather- it can take high amounts of abuse. Like I said- these come in all sorts of flavors, but I'll always love my leather...and feel good knowing that more of that animal was used than just it's meat.
Definitely worth checking out! A really nice, quality accessory that gets the job done and looks pretty swank too!
