PhotoFit® Instructions

While we have thousands of templates ready, we may need a Photofit image of your bike to ensure a perfect fit. Please take your Photofit image following these instructions.

Photo should be 10-12ft away,  level with the frame, bolts exposed, with both wheels visible. If you only have the frame, get low enough to be level with the triangle and back up 10-12 ft away. **Include water bottle(s) for half framebags & wedges.**  This helps us bring the bag about 1/2″ from your bottles. See example Photofit images here.

 

 

 

1 review for Ultra-PE Custom Framebag

  1. John McMillan –

    I reached out to Greg and Rockgeist about a frame bag that would fit my Sklar PBJ for an Eastern Divide Trail bikepacking trip that I decided to pull together on short notice. Everything about the experience with Rockgeist exceeded my expectations. The bag is perfect (it looks both amazing and bombproof) and fits my frame exactly. And they worked it into their queue so that I had it in hand in less than two weeks. Outstanding. Thank you.

 Differences Between Ultra-PE Fabrics for Bikepacking

Choose UX10 if...
You’re after the light fabric available. It has significantly less weight then other woven options and better water shedding ability.

The UX10 ST adds a taffeta backing for better stitch retention for a little more weight (3.4 vs 2.5 oz/yard2). This backing makes it look a solid white while the UX10 is see-through.

 

  • Fabric Made USA
  • PFAS-free finish
  • UX-10 is see-through (image right), UX10 ST is more white (image left).
Hypertec fabrics UX10 xpac

HyperTEC™ UX10

The lightest pack fabric we carry. UX10 (image right) is built from a 100% woven Ultra-PE face, an Ultra-PE X-ply mid-layer, and a waterproof inner film.

The UX10 ST variant (image left) adds a taffeta backing that improves stitch retention for high stress seams.

Core Benefits:

  • 100% Ultra-PE face fabric (not a poly blend) for higher strength and better water shedding ability.
  • UX10 is the lightest Ultra-PE fabric you can get from Rockgeist.
  • 2.5 oz/yd2 for UX10 and 3.4 oz/yd2 for UX10 ST.
Choose Dyneema if...
You’re after ultralight with a flashy outer finish.

2.92 ultralight weight comes at the expense of abrasion resistance. We only recommend the 2.92 if you understand the limitation of this fabric and take care of your gear.

If you like the look of dyneema but want a more “set it and forget it” framebag then pick the slightly heavier 5.0 variant.

 

  • Fabric Made in USA

Dyneema® Composite Fabrics (DCF)

A shiny non-woven composite laminate which is reinforced with Dyneema® fibers mated to a matte polyester backing.

Core Benefits:

  • Dyneema won’t absorb water in rain
  • Unique, flashy patena
Choose Ultra 200/400 if...
You’re looking for the best balance between ultralight and high abrasion resistance.

The lighter 200 variant is more abrasion resistant than the 2.92 Dyneema but still considered “ultralight”.

The 400 variant adds significantly better abrasion resistance at the expense of a little more weight.

In our opinion this 400 variant is one of the most durable yet ultralight pack fabrics available.

 

  • Fabric Made in Asia
  • PFAS-free finish

Ecopak® Ultra 200/400

A mix of woven Ultra-PE and Polyester, laminated to a polyester film.

Core Benefits:

  • Highest abrasion resistance in its weight class
  • Exceptional stitch retention and overall durability
  • Available in white, black, grey, navy 
Choose Ultra VX-40 if...
You value durability over ultralight. While this is the heaviest of our Ultra-PE fabrics it has maybe the best abrasion and cut resistance of the group.

 

  • Fabric Made in Germany and USA
  • PFAS-free finish

X-Pac® Ultra VX-40

Similar to Ecopak’s Ultra series this is a mix of a shiny woven Ultra-PE and Polyester laminated to a polyester film. One of the first fabrics to weave Ultra-PE into a traditional fabric base.

Core Benefits:

  • High abrasion resistance
  • Exceptional stitch retention and overall durability

A stiff plastic base of the framebag is bolted to your frames water bottle bolts. We can bolt your down tube, top tube, or seat tube all from your photofit image. The bolt holes are slotted to allow for a perfect fit and are gaurenteed to match up to your bolt patt

erns. Bolts and washers are included in your order.

PRO: Eliminates velcro straps that interfere with water bottle bolts on the underside of your downtube. Also creates a clean look and solid anchor.

CON: Takes more time to take the framebag on and off the bike.

The map pocket is positioned on the non-drive side and is a full length pocket with no depth. Perfect for small, flat objects such as maps. Internal sleeves exist inside the map pocket for framebags with enough space. A channel also exists to connect the map pocket to the drive side to allow electronic cords to pass through.

The horizontal divider has a zipper entry positioned on the drive-side. There is a removable velcro divider that creates a horizontal partition when in place. When opened up, you have full access to the entire bag from the top zipper entry.

Zip horizontal divider

Lace-up connection to your top-tube. Standard cord color is black.

PRO: Creates a solid, distributed frame connection. Less abrasive to your frame’s paint than velcro.

CON: More time consuming to install/remove framebag compared to velcro.

Rockgeist Lace up framebag

Make the most of your packing space with a flared front end. The flared nose is built 4.75″ wide at its peak with a variable 1″ velcro connection on top, a hydration port at the point, and a 2″ one-wrap velcro connection connecting to your down tube.

Framebag flared nose

Hang loops consist of a “sleeve” with a daisy chain under your top tube. A pump can live behind the sleeve leaving One-wrap velcro straps to wrap other objects such as tent poles. The Velcro straps are removable to free up space when not in use. This arrangement helps prevent clutter from building up at the bottom of your bag. 

Framebag showing hang loops

A durable hypalon flap covers your zipper to deflect rain and snow from entering through your zipper teeth. If selected, we will cover all zippers on the bag.

Zipper Storm Guard framebag

A discrete pocket sewn to the inside spine of your framebag. Meant to contain your Apple Air Tag or similar GPS tracking chips. Used to help find your bike in case of theft while out bikepacking.

Air tag pocket framebag

This pocket is made from stretch mesh woven with Ultra-PE fibers. This creates one of the most durable mesh fabrics on the market. Default position is on the non-drive side panel, in the front half of the bag closest to the stem area.

Typically this pocket is used to carry trash and other small items.
