The TEKLITE TT 660 provides separate padded compartments allowing you to store 660 cc worth of items all while staying organized. The fleece-lined divider keeps your phone protected, fitting large phones with cases up to 76 mm x 151 mm tall. The second, larger compartment is ideal for your nutrition, keys, tools and other essential gear. The divider is easily removable giving you one large storage compartment. Twin zippers provide quick access to the items you need, while the light grey interior allows for easy sighting. Easily transfer the Teklite TT 660 to any bike in your stable with the flexible mounting options. Mount using the included silicone-coated straps or via bolts into your bike’s bosses. 3 sets of mounting holes and 6 different strap positions allow you to place the Teklite TT 660 where you need it most. The anti-sway steerer tube strap and non-slip base keeps your bag in place. The patent-pending molded zipper pulls fit snugly into two molded garages, sealing and preventing debris from entering the bag. The dirt-deflecting zipper flaps are specially designed to protect the zipper from dust, grit and water, while remaining easy to open and close while riding. Constructed of ultrasonically welded TPU coated 600D nylon laminate for superior tear resistance along with a special Matte finish. Includes non-slip straps & non-slip underside base for additional stability when fully loaded. 2 mm of closed cell insulation is embedded in the sides and bottom of the bag. Additional high strength stiffeners help to maintain shape. A special matte finish eliminates reflective sun glare and logo is made of a highly reflective liquid to help ensure you’ll be seen in the dark on those long explorations.

I've left this on the bike and the bike on a carrier traveling a couple thousand miles through wet and wintry weather. I didn't even have a bike cover. And still the zippers function smoothly and everything inside is protected. Impressive.

Well designed. Holds on nicely. A good size, though my phone is close to the limit.One zipper just failed. Probably 15 rides, over 3 months.

I have had a bunch of top tube bags, and this is by far the best. It is bolt on with straps also included if you roll that way (I actually use both). It is very streamlined yet has two roomy compartments that hold my iPhone 14Pro in a shell case and my wallet easily. My first one lasted three years and I'm rough on my stuff as an avid gravel cyclist. I could have fixed the issue which was the zipper flange that came apart but opted to just buy a new one. It is very waterproof. One thing I noticed is that they included bolts with bigger flat heads this time. Yay. On my first one I had to add washers so kudos to Dawn to Dusk. It's a little pricey but I deem worth it.

The pocket holds my Iphone proMax with little issue. That's all that fits on one side, the other side is similar in size so if you carry a phone, dont expect to fit a tube, tool kit and CO2 cartridge with control head in the other side. Perfect for a cliff bar and some gummies and a few bucks though. Haven't had an issue with water ingress.

This top tube back works great with my Felt Broam 60 gravel/bikepacking bike which has integrated equipment mounting holes. I noticed the aftermarket hasn't quite caught up to top tube bolt mounting bags yet and was pleasantly surprised to find this unit at a relatively affordable price that isn't too tall or too wide. I opted to position the bag as close to the headset as possible and used the front strap to add additional stability and minimize swaying. Many reviews indicate trouble with the zipper and I could immediately understand the issue. The zipper does not move as freely as one sewn into a jacket or a backpack. The top seam is a very tight seal for minimizing water intrusion. To ease use, I sparingly applied some gear oil to the zipper teeth to minimize corrosion and loosen the zipper operation. I worked the zipper open and closed at least a dozen times making certain to observe the pulling angle until the operation was smooth. I carried my iPhone SE2 on the smaller side (inner separator is adjustable) and small tools including a small pump in the other with no issues.

4/2024 UPDATE - replacement bag, the zipper only made it 11 months before breaking. Going to request another bag. Feel constantly replacing this bag every 12 months now.5/2023 UPDATE - after 14 months one of the zippers broke and the adhesive holding the center divider no longer holds. Now stuck with bag with one functional zipper and no protection from my phone. Emailed Dawn to Dust and are sending me a new bag with improved zipper!10/2022 UPDATE - after 6 months one of the zippers got corroded (from sweat) and no longer works. Ended up soaking the bag in hot water and soap for 15 mins then taking a toothbrush to scrub the zipper. Eventually the zipper freed up. If you sweat lot, give the bag a deep clean every 3-4 months.Goals for top tube bag - hold my iPhone 13, my car keys, ID/cash, and 2-3 gels/bars. What I was putting in my jersey now in the bag. Overall bag does the job: Easily unzip while riding, my legs don’t hit while pedaling and fits all my required gear. But it’s not waterproof and doesn’t zip if it’s overpacked with stuff. Compared to other top bags, it’s one of the better units and I’ve got tons of complement’s about its size and function.

This bag is great looking on the bike, extremely clean lines, small logos. The way the zipper pull tucks into a little pocket works well and keeps it from flapping in the wind. The bag is tiny, it holds five or six gel packs at most. I use mine with the built in bottle mount bolts included on my frame's top tube. It's very secure and doesn't wobble at all.My one issue is that the top edges are fairly sharp where the two pieces of fabric come together, and if your leg rubs against them too many times, it starts to abrade your skin. Maybe that will soften over time.Over-all very good though and a good price.
