I bought this bag for a 700 mile Bike Tour along the Euro Velo 1 on the Atlantic Coast of Ireland. This was my solution for my camera gear and other 'quick access' items. The bag is a bit wide, so it might get in the way of your hand position depending on your handlebars. I bought the Red Shift Kitchen Sink wide drop bars so I didn't have that problem, but to be fair any bag like this you'd probably run into the same thing. This bag got DUMPED on by heavy rains along the cliffs of Moher, but all of my gear kept perfectly dry. The fabric/material held up, and the bottom is even reinforced which is nice. I was a bit skeptical of the straps as I've had other bags loosen, rub against my front tire and ruin the material of the bag... but I didnt have that problem here. I don't use it too often unless I'm going on a multi-day trip, but I've been so happy with all of Roadrunner's bags, attention to craft and detail. I recommend them to everyone!!! They are a little pricier, but you know what they say - BUY NICE NOT TWICE!

I've tried so many bags, and this is my favorite one ever. I overpack for everything, and I haven't managed to come close to filling this bag up. The front pockets with the super reflective stripe are convenient and hopefully help me be even more visible. To keep the bag off the cables, I made a standoff type thing from a Wald basket holder with a bar welded on the top. The has the added bonus of letting me remove the bag without needing to unbuckle the straps, which is pretty cool.

I searched for a long time for a bag that meets multiple use cases and looked good on my sliver-gray steel all-around bike, and I found it in the middle earth.

I wanted a bag that can stay on my all-around bike on the handle bar or sometimes the rear rack for a wide range of uses:
- About town: a place to pack my purse + jacket - with expansion space to pick up groceries
- Working at coffee shops: purse + iPad or 13" Macbook
- Weekend day tours: space for a camera in a bag, extra clothes, larger tool kit/medical kit, snacks

The middle earth does all that--although for a big grocery run it needs to move to the rear rack (big = 1/2 gallon milk, two big things of yoghurt, 12 eggs, two containers of berries).

This is not a bag that's easy on/off the bike (I have another one for my ebike that's much quicker)--but because it's a bit tricky to remove I don't mind leaving it on there and just taking out the contents when I go into a store.

The one challenge I still have: my handlebar mounted light won't work unless I make the bag as small as it can be. I might end up buying a braze-on mounted stub so I can move it if I really need light for night rides. (The flashy works great during the day on the front of the bag, though.)

The perfect medium sized rack-less bag. I bought this bag to complement my Velo Orange Biggish Bag (also made by Road Runner). The sizing on my Middle Earth Jammer ran large which is perfect. The expandable/collapsible volume makes it perfect for carrying a variety of items, including those bulky ones. Looking forward to many more years with this well-crafted bag!

This bag has room in depth and width to carry my computer and some goodies without adding too much weight. This bag alleviates the sweaty back effect when riding with a backpack. When I called Road Runner, the team member was knowledgeable and friendly. She was also willing to do a custom order! RAD!!! After using the bag for a week, it is clear that this bag can handle rain and salty air. For those will short bars, this is not your bag. Also, if you have longer bars, you might want to invest in a foam spacer kit. The bag takes a lot of real estate on the bar. There are some sweet little easily-accessible front pockets that are great for carry those tiny essentials, like a credit card and cash for that cool coffee shop on your route to work.
The bag quality is durable and waterproof. The straps are smart with several attachment points. The buckles and connectors are top notch. I can't wait to order more bags!!!
