  • Variable velcro attachment to the top tube near your stem. This allows compatibility with your choice of top tube bag, including the Rockgeist Cache bag.

  • If a horizontal divider is not chosen, large framebags at risk for leg rub will come with a vertical divider.
  • Hydration/electronic access

PhotoFit™ Template Creation: A strategic photo of your bike is used to build all Rockgeist framebags. PhotoFit™ offers several advantages over physical customer-traced templates. The most important advantage is that it eliminates template errors and helps avoid zipper stress, maximizing packing efficiency, and ensures strap compatibility with existing bags/frame features.

    I’ve had this bag close to 3 years and it’s like brand new… minus all the mud! Seriously though, this bag is awesome, well built, and has stood up to everything I can throw at it (or in it!).

    Love this bag! We bought two for our bikepack trip of the Colorado Trail, and they took a beating. We had a really wet July and both were covered with mud, but open and closed without any issue. A quick hose down after and they are like new. True mudlust!

    I’ve had the Mudlust bag for about a year now. Used it this year on the AZT and gave it a good pounding. I’ve always tended to overload bags and that trip was no exception. Despite unrealistic product expectations, it had no zipper or other issues at all. I’ve shown it to other bikepacking buddies and the comments have consistently been of quality and features. Also, people have wondered how Greg managed such high quality at such a price point, sewn with his own hands largely if not completely. I also have his version of a gas tank and feedbag which are of the same quality. You’re looking in the right place for your gear!

    I’ve used my Mudlust for about a year now. I have beaten this thing to death and it never gives up! Raced Cohutta Cat, Hurracan 300, Skyway Epic and about to race the Trans North Georgia. Wouldn’t consider anything else for my epic adventures!!

    When I got my new bike last year the first thing I did was dial up Greg for a new Mudlust and as usual I was not disappointed. I had a number of custom touches built in and the thing has been bombproof. Even overstuffing it like I usually do (those tallboys take up more room than you think) it has stayed solid as a rock. Quick spray off at the end of any dirty ride and she shines like new.

    Goodbye camelbak – Hello Mudlust. This frame bag is tough, functional and looks badass. Greg was great in guiding me through the custom options for the bag. The whole process was very fast and Greg couldn’t be friendlier. My bike bag arrived in the mail shortly afterwards and ever since I’ve had it on my full suspension frame. I’ve ridden through the wettest Pisgah has to offer with this bag on my frame. It keeps the contents dry and protects them from mud and grime. I have a 1 1/2 liter hydration bladder in the bag, tools, keys and a map when I ride – with storage space left over. If you are tired of having that heavy pack dig into your shoulders all ride, get your Mudlust on and ditch the backpack. Highly recommended and a great company.

    Being new to bike-packing, I needed a frame bag for my bike’s rather odd-shaped frame. No major manufacturer produced an item that fit my needs. I found Rockgeist on the web, communicated directly with Greg, (the owner) about what I needed, sent in a template, and couldn’t be happier with the product I received.
    The frame bag was produced exactly to the specs I provided, is made of high-quality, abrasion-resistant materials, and fits my bike like a glove. The waterproof zipper is indispensable, and it’s angled zipper-garage is a nice touch. The bag has internal padding which holds it’s structure well, and all webbing is stitched internally, giving the outside of the bag a clean look.
    This bag has been an integral part of numerous successful trips and continues to hold up well, despite some harsh conditions and a few unfortunate dismounts.
    All in all, and perhaps more noticeable than the great features and durability, is the craftsmanship of the bag. It’s obvious that Rockgeist is a company that cares about the construction quality and trail-worthiness of their products. I’m looking forward to many more years of use from this well-made frame bag.

    I have been looking for a custom frame bag for my Salsa Mukluk. It has unique curvy geometry. I had a hard time pinning down other custom guys. Greg responds promptly and finished the bag on time. The bag fits like a glove! Quality of the bag is outstanding.

    The mudlust framebag has become one of my favorite pieces of gear! The large YKK zipper is very easy to open and close while on the bike and my gear stays dry even during heavy downpours and quick dunks underwater during river crossings. The materials and construction seem to be of the highest quality possible. The photofit instructions were easy to follow and the bag fits my custom steel frame perfectly. The bolt-on option is really nice also and provides a very clean look.
