  1. Installing the Bluff Bag before other handlebar bags is generally best. While this bag is versatile and will play nicely with all of our handlebar and frame bags, mounting is much easier when it is the first bag installed in your cockpit.
  2.  Loosely install the top tube straps before installing the head tube strap.
  3. Install the head tube strap as the 3rd mount for the bag, which keeps the bag snug against the head tube and eliminates all swaying and rocking of the bag. 
  4. Go back, tighten the top tube straps, and check that all straps are tight and ready for action. 
  5. Excess webbing should be tucked into the preinstalled elastic loops on the top tube straps. 
  6. Shred!

Best bag ever!

I rode in my first century last weekend. It was a small local fundraiser: every other support stop was water only, so I had to carry extra food and drink mix. I also carried sunglasses, a change of gloves, a face wipe, sunscreen, lip balm, and small first aid items. Everything fit perfectly. It rained some on the route and my items stayed dry. (Not so lucky with my saddle bag.) Top quality bag. I love that it is made in USA. Highly recommend!

Can hold an ear of corn. Maybe two

I love this bag so much. Very spacious and well made. The colors are delightful. It attaches well and it doesnt drift off to one side like my old top tube bag from a more established brand did. Super solid bag.

*TOP* tube bag

So, I tend to beat the s**t out of my gear…

I bought this bag to replace a more expensive, less durable race top-tube bag for my bike. This bag rates at *half* my previous bag’s stated capacity…Somehow, however, it seems as though I can fit even more stuff in the Bluff bag, due to it’s intuitively designed dimensions. I can easily fit my compact tyre pump, snacks, keys, and phone - along with other easily and necessarily grabbable items 😁 - Often adding a thin shirt and more with space to spare. The heavy duty zipper never fails even with my admittedly clumsy operation, and the overall craftsmanship garners confidence. The fact that this product is made here in the States is more than simply bragging rights - it’s an example of what is possible while utilizing appropriate quality control when producing a product. I now rely on this item, and will continue to use it to shape my bikepacking methodology into the future.

Great job!

So much room!

I really love this top tube bag. Has a ton of room and the inside pocket makes it easy to separate items. Keep rocking these bags Road Runner!

Made in the USA!

I was super excited to pick this bag up in LA. I love buying American made goods. This one is no exception; this bag is sturdy, a great size, and just what everyone needs on their ride. I’m excited to see how it continues to wear on the road.
