I recently purchased this reverse top tube bag and have to say that the quality is excellent. On the Trek Checkpoint+, the screen on the top tube restricts the use of regular frame bags near the stem, so this creative location is helpful. The quality of the Velcro straps is excellent. The straps are plenty long for large frame diameters, and the closures are very sticky, unlike the cheaper Velcro that comes on many of the other bag brands. The inside of the bag is lined and has utility pockets. If someone is on the fence about buying this higher-priced product, let me say that it is well worth the money.
FIrstly, its been a worthwhile purchase. Sizing is great for small pump, irons, tools and quick snack. But...not waterproof and velcro strap loops on bottom have un-stiched so straps now have only 2 of 5 loops to play with. 3 months usage.
Really enjoy this bag. Provides additional storage for longer rides. Great quality and stays put.
Built super well and fits great.
