ROCKBROSBike Triangle Bag, Waterproof Bike Triangle Frame Bag, 2 In 1 Multifunctional Bicycle Storage Bag, 2L Cycling Pouch for Mountain Road Bike

Good bag for the price and the bike.

This Rockbros triangle bike bag is made of quality materials and is well thought out and designed. You get a lot of storage space with minimal disruption to your biking experience. When compared to under seat bags or even saddle bags, this option fits neatly in the main triangle of your frame without the need to install a bike rack. You have much more space available than a traditional seat bag. You'll have room for your phone, extra tube and tools and even a jacket. The material is water resistant and durable. The main compartment secures well with strong hook and loop strips. The smaller bag can be separated from the main triangle bag, if desired. You can elect to attach the smaller bag to the handle bars with the included hook and loop straps. There are five straps included so you can install the main bag with three straps and the handle bar bag with two straps. You also get a shoulder strap for those times when you need to remove the bag from your bike and take it with you. Even the zippers are of good quality and water resistant.

This bag has ample storage space and is very well-made. The fabrics, stitching, and reflective tape have a premium look and feel. Installation is quick with the included hook and loop straps. I initially installed the straps in the wrong orientation as seen in the photos. The smooth side of the straps should go against the frame. The bag features a rolling closure design, with a hook and loop seal, and it's what I like most about the bag. This design protects the bag's contents from water and dust / debris, and is critical when riding in the elements. I am beyond pleased with this awesome bag from ROCKBROS!
