Frame Jig – Main Extrusions Not Included

Update 11/11/26 - The current ship date for this item is 11/30/26

This version of the Flume Frame Jig does not include the main horizontal and vertical beams. By sourcing these separately, you can significantly reduce shipping costs, especially for customers in Europe.

Everything else required to assemble the jig is included, including adhesive scales for attachment to the main extrusions.

The two main extrusions you'll need are 80mm x 80mm profiles with an 8mm slot, in the following lengths:

• 600mm (vertical beam)

• 1200mm (horizontal beam)

There are several suppliers in the EU and UK that carry these profiles. Motedis is one option. The link will take you directly to the profile size you'll need.

Materials and Finish
All components that contact the frame, including cones, pucks, and bottom bracket adapters, are made from 303 stainless steel.
All remaining components are machined from 6061 aluminum and shipped with a raw, machined finish, as shown in the photos.
Anodizing is available for an additional charge and increased lead time.
The aluminum extrusions are high-quality, tight-tolerance profiles from Misumi.

Frame Compatibility
From 20” front load cargo bikes to 32” wheel XXL mountain bikes, this jig will accommodate them all.
The maximum horizontal distance from the bottom of the head tube to the center of the rear axle is 1100mm which is long enough for virtually any standard frame and also some cargo/longtail scenarios. If an even longer horizontal extrusion is needed, we can make that happen.
The jig accepts any size Anvil/PMW style dummy axle.
Dummy axles are not included, but can be purchased separately with your Frame Jig.

Included Adapters:
Head Tube Puck - A dual-sided lower head tube puck compatible with both 1-1/8" (EC34) and 44mm headsets is included.
Other sizes, including 1" (EC30), can be made upon request for $50 each.

Bottom Bracket Adapter - An adapter for 68mm and 73mm threaded BSA bottom bracket shells is included.
A 68/73mm T47 adapter and T47 end cap are available for an additional $100- available here.

Optional Accessories and Upgrades:
Park Repair Stand Mount ($150 USD) - A repair stand mount that is compatible with shop-grade Park PRS repair stands.

Stay Holder ($150 USD) - Positions and holds chainstays and seatstays making sure they're properly centered.

Offset Seat Tube Adapter ($150 USD) - Accommodates seat tube offsets of up to 70mm.

The Centering Fixture shown in some of the photos is sold separately.

Measurement Scales
The horizontal and vertical beams each have a measurement scale. The horizontal scale references the distance from the bottom middle of the head tube to the center of the bottom bracket and the rear axle. The vertical scale references the distance from the center of the bottom bracket to the bottom center of the head tube.

Horizontal Beam – Head Tube Bottom (X)
Measures the horizontal distance from the bottom center of the head tube to the center of the bottom bracket and rear axle. In BikeCAD, this measurement is called "Head Tube Bottom (X)."

Vertical Beam – Head Tube Bottom (Y)
Measures the vertical distance from the center of the bottom bracket to the bottom center of the head tube. In BikeCAD, this measurement is called "Head Tube Bottom (Y)."

Horizontal Chainstay Length
This is measured by subtracting the reading at the bottom bracket assembly from the reading at the dropout assembly.
