    All in the details! I reached out for a top tube bag when stock of anything seemed pretty scarce before my first 100 mile ride. I got a different in stock brand in case it didn’t arrive in time. While both were nice. The Rockgeist bag just felt a little nicer. Seems more structured, the Velcro is much wider/supportive and the little details like that glow in the dark zipper pull are all small but noticeable differences. And it made two hours from me. I’ll definitely be coming back for more bags as the need arises, which should be soon.

    My cache top tube bag has seen years of abuse and is still performing flawlessly. Gallons of sweat, buckets of mud. Everything I could possibly throw at it. Takes a licking and keeps on zipping! I can’t recommend this bag enough.

    Rockin’ with Rockgeist Custom Cache Top Tube Bags. What’s not to love about Rockgeist Top Tube Bags? You can customize just about anything on them. The quality is among the best in the industry. Customer service is very pleasant and professional. I use both of my Rockgiest Top Tube Bags for holding my phone, cache battery, and other small electronics. For this purpose, Rockgeist sewed in a pocket inside the left and right panels. It works beautifully. My most recent order was for a bolt-on top tube bag. The bolt spacing was unusually long, and Rockgeist contacted me to ensure I had measured correctly. I love all of the different fabrics there are to choose from. Kudos to Greg and Company for providing high-quality, customizable gear. Ride On!

    I bought a large top tube bag at the beginning of the season after borrowing a friend’s and feeling reluctant to give it back. Very well-designed and made. Ive got a collection of bags and this one is used the most by far. So nice to be able to easily access things while riding.

    I have the cache size large bag on my salsa Fargo and I love it!! The Velcro keeps the bag secure and it holds all of my smaller essentials when I am out and about. I bought it Gravelo in Asheville.

    I’ve got one of these in large and it’s the bomb! It’s got enough space to fit a 2xl windbreaker, phone, keys, knife and small wallet, but be out of your way when riding! After two years of being packed full on a regular basis it’s still in excellent shape. Cant recommend it enough!

    I bought the xl cache top tube bag and it has served me very well. I appreciate being able to keep my Sinewave Reactor in the bag, as the cable can be routed through the bag’s cord access slot to connect to the dynamo hub. It adds a stealthier method to safeguard it. The main zippered body holds so much, it is a pleasure. The extra zippered pocket on the side allows quick access to smaller items and is separate entity from the top opening. Best of all, it has remained in place without leaning off to the sides. This has been my favorite accessory bag to date.

    I just got the small top tube bag with with bolt on holes for my gravel bike. I’ve been on a few rides now and it fits perfectly and looks great. It is has a significant amount of storage space – my phone, wallet and many other things fit. Super happy with this bag!

    Only regret is not buying it sooner! The fit is totally tight and ‘flush’, unlike other setups. My moonlink spacer is beneath my stem, securing the bag with the bottom strap. I’m using a 40mm Syntace megaforce 2 with a garmin K-edge top cap, also. I’ve no problems with stability or the bag flopping around. For what its worth, I can store my everyday wallet, Galaxy S8, keys, Stans dart, and a snack in the Cache comfortably. It’s also easy to open, thanks to the what feels like a top tier zipper. I ride in southern California where it’s mostly dry, so I can’t speak to it’s moisture wicking capabilities, but it sure inspires confidence. I trust the contents to stay dry. The VX-21 material used is not only light, but feels substantial – if that makes sense.
    Overall, 5 stars! Thanks you!

    Incredible bag. From the moment I bolted this bag onto my bike, I loved everything about it. The form, fit, and function of the bag are all impeccable. It’s clearly made from high quality materials, and with attention to detail. The biggest test of this bag was when I was caught in a ~45 minute downpour about a week ago. Everything stayed dry inside, even on the side pocket. Rockgeist makes amazing products and would recommend to anyone looking to expand their bikepacking rig.

    I’ve been schlepping my stuff around for a few weeks now in a bolt-on XL and I’m thrilled with how well it’s made, fits and operates!! 5 stars!

  13. Kristin (verified owner)

    I have the small cache top tube bag with bolt-on holes. My bag fits perfectly! I love the quality and love that I have a bag fitted specifically for my bike. It feels very durable and fits a decent amount of things.

  14. Luke (verified owner)

    A great bag. Stiffer than most top tube bags I’ve used so it holds it’s shape well and doesn’t bulge. The XL is long and thin meaning you don’t hit your knees on it every pedal stroke.
    It pairs wonderfully with the Spacelink for a super solid connection to the bike. I’m using mine with Honeypot feed bags and the whole system integrates perfectly.
    I also got great customer service from Greg who never tired of answering all my lame emails! Great gear from a great company.

  15. Jeff Thompson

    While not my first bag from Rockgeist, the XL Top Tube bag quickly became my new favorite! It holds a plus sized phone and still has room for a few snacks, the side zippered pocket is perfect for a card and a few dollars for that longer ride!!!

    I’ve had my Cahce bag for about a year now and it has gone on quite a few long weekend tours, S24Os, and has done commuter duty on two different bikes now in varying conditions. I’ve typically put snacks and my phone in the bag, and it makes checking directions and refueling throughout the ride (without stopping) a breeze! The one downside is it’s ability to keep the water out; the fabric (x-21 for mine) does it’s job, but the zipper lets moisture seep through on any ride longer than about 1 hour with constant rain. These wetter rides have been in the so-called atmospheric rivers that hit the California coast a few times a year where it dumps several inches of rain in a very short period of time. That being said, the half-framebag made by Greg (with the burlier zipper) did not experience the same issues, so it is likely a combination of the position of the zipper (right on the top of the bag) and the zipper itself, that contributes to the infiltration of moisture.

    Overall though, It is a great little bag that is well thought out and built extremely well and continues to perform on just about every ride.

    I have this bag on my Gravel/Road bike, it is a high quality bag that is very usefull for both bikepacking and commuting. I am surprised at the amount of stuff i can fit into this small bag. I have a tube, multi tool, tire levers, as well as my phone, wallet and keys in this bag typically. Mine is made out of X-Pac Liteskin fabric to match my half framebag. In light rain it allowed no moisture inside of the bag.

  18. Katie V. (verified owner)

    I bought this bag and it holds everything from my wallet + phone + keys + sunglasses on a normal commuting day to these same items plus other odds and ends (TP) on a good ol’ bike tour day. It’s a super fun bag, mostly because of all the colors there are to choose from:-) This seriously is my favorite little bag from Rockgeist because it’s so cute, and I especially love how when you zip it up, the end of the zipper fits under a little lip to prevent rain from getting in. Speaking of rain, on our bike tour in Spain, never once did the contents of the bag get moist during our days of rain. Oh, and the inside of the bag can be a different color than the outside! SO FUN! Thanks, Greg!

    this has quickly become my favorite piece of baggage on my bike for tours and everyday riding as well. on tour i usually load it up with a multi-tool, headlamp, small bleach dropper, lighter, snacks for the day and can even fit in a thin pair of gloves or small beanie on the fly. i never notice it when standing up in the saddle to pedal, and i like the personal touch of the glow-in-the-dark zipper pull as well. i’ve ridden about 800 miles with his bag, and so far it looks brand spankin’ new. definitely recommended!

    Had this bag made to match my custom frame bag and it has been on my bike since it arrived. Perfect size.

    I recently switched frames, and my Apidura bags didn’t fit quite right on my new hardtail. I ordered custom Mudlust, Medic top tube (saddle side), and Cache top tube bags from Greg. I had been through a few other shops that either never returned my email, or kept my templates for months without ever looking at them. I’m so glad they didn’t work out, because the process and results with Greg and Rockgeist have been even better than advertised. I can’t believe how easy the template photo process was, and how well it worked. My framebag just cannot fit any better. It’s perfect, and even more sturdy and durable than I expected. I hoped they would be as well made as the Apidura frame bag, but the Rockgeist quality blows the Apidura out of the water. The zippers, padding, and fit & finish is the best I’ve seen. I will absolutely be ordering the Foxglove saddlebag and Barjam harness now that I know how great this stuff is.

    This is the perfect everyday bag, I love it. Really ideal for any kind of biking – bike packing, road-cycling, city biking, whatever. It’s actually the only bag I keep on my bike at all times. I use it for all the things I want easy-access to without having to stop, but there’s room still for other essentials that I just want to keep on me. It’s where I keep my sunglasses, keys, wallet, and phone if not mounted, energy supplements, and other things I might need off and on. Right now mine has three Gus, a Lara bar, two packets of aspirin, my multi-tool, a travel squeeze-tube of vaseline, a compass, a whistle, a small switchblade, and my arm warmers. On colder morning rides it’s where I usually put my balaclava when it warms up. I also keep face sunscreen in there, and bug spray in warmer months. Can’t recommend it enough, definitely my faithful go-to, really happy with it.
