Retrofit - Di2/EPS


Di2/EPS RETROFIT

Quality bicycle frames are built to last a lifetime, invariably outliving several generations of component technology. The advent of electronic shifting has brought welcome advances in precision and performance, and the ability to integrate wiring systems into the frame provides protection and durability while maintaining a tidy look.

We regularly retrofit both steel and titanium frames for our customers with the same tools and procedures we use to build our own frames. Our unrivaled experience in titanium frame building and our longstanding relationships with component manufacturers ensures that all retrofits, repairs, and modifications are done with skill and precision, made to last.

NOTE: WORK AREA / FINISHING
All welding and brazing work requires a clean an uncontaminated work area. Any paint or decals in the affected areas will be removed during prep work. Any detailed cosmetic work required post-repair, including complete custom graphics or restorations can be accommodated on site for an additional fee.

TITANIUM FRAMES: Our basic retrofit services include cleanup/finish blending on titanium frames with bright brushed or matte blasted finish but does not include any repainting or refinishing with graphics. Any additional refinishing and/or restoration work required, including custom paint and graphics, is available for an additional fee.

ALL FRAMES: Paint and powder coat must be removed ~8 inches in all directions from the work area. For steel frames, a complete strip and recover with powder coat is recommended for the most economical and durable refinish. Any additional refinishing and/or restoration work required, including custom paint and graphics, is available for an additional fee.

Includes:
   * Precision Di2 port drilling.
   * Removal of mechanical cable stops on raw/unpainted titanium frames.
   * Finish refresh (no graphics/masking) blending/cleanup on raw/unpainted titanium frames.

PRICING, DELIVERY, and SPECIFICS
Every retrofit project is unique: please email us with photos of your specific frame and desired application for a specific price estimate including all modifications, refinishing, and new parts.

If you're shipping the frame to us it will need to be completely stripped of parts, down to the bare frame.
Dis-/re-assembly of complete bikes is available for an additional fee.

Repairs, retrofits, and custom fabrication work requires complete pre-payment of our full quote for labor and materials. Unfortunately we cannot make exceptions.

Retrofit - Disc Tab


DISC TAB RETROFIT

Retrofit - Disc Tab


DISC TAB RETROFIT

Adding a disc brake mount is a great way to increase stopping power on bikes originally built with rim brakes.  This is a retrofit that we do regularly on titanium and steel frames, and some forks.

BASIC DISC TAB RETROFIT
Includes the cost of labor, the disc tab, and a short brace tube between the seat and chainstays. Non-disc frames were not designed to carry the braking load on a single side at the dropouts. The brace tube is required to ensure stability over time. No additional guides or modifications.

FULL DISC BRAKE RETROFIT
For a comprehensive disc brake conversion with a clean and purposeful appearance we can also add full hose/housing routing to your frame.
We recommend 2-3 guides on the seat-/chain-stay to keep the brake line away from the rear tire, and one on the down-tube/top-tube between the existing stops to keep the brake line in place.
Cantilever bosses and obsolete cable stops can also be removed.
 

WORK AREA / FINISHING
All welding and brazing work requires a clean an uncontaminated work area. Any paint or decals in the affected area will be removed during prep work.

TITANIUM FRAMES: Our basic disc tab retrofit services includes moderate cleanup/finish blending on brushed or bead-blasted titanium frames but does not include any repainting. Additional refinishing and restoration, including custom paint work, is available.

STEEL FRAMES: Paint and powder coat must be removed ~8 inches in all directions from the work area. A complete strip and recover with powder coat is recommended for the most economical refinish. Additional refinishing and restoration, including custom paint work, is available.
 

ROAD FRAMES / RESPACING
While clearance for a disc brake rotor is generally not a problem with mountain bike frames, it can be a major consideration with road frames using anything larger than a 140mm rotor. To facilitate the use of a 140mm rotor we only use ISO disc tabs.

Most older road bike frames were built with 130mm rear dropout spacing, while most disc brake rear hubs are 135mm spacing. We can respace your frame, which includes squaring the dropouts, to accept 135mm rear hubs.
 

DISC BRAKE COMPONENTS
We can supply any and all components needed to convert your bike to disc brakes including brakes, rotors, wheels, et cetera. We offer great pricing on components and can provide parts from any manufacturer.

Retrofit - Potato Chip


POTATO CHIP RETROFIT

Retrofit - Potato Chip


POTATO CHIP RETROFIT

Clearance. It's not just for top secret documents and air traffic control anymore!

Legendary for their durability, titanium frames generally have outlived the sizes and standards of the era in which they were built. As wider tires, belt drives, and other component changes have come on to the market or become the flavor of the day the owners of those trusty titanium frames require more clearance to maintain compatibility.

"POTATO CHIP" RETROFIT
The most direct and efficient way to create clearances is to simply remove the section of chainstay creating interference.

In this process we can cut clearance into the chainstays and close up with 'potato chip' welded in.

This procedure is applicable to both exterior clearance for belt- and chainrings and interior clearance for tires and has been performed countless times with no failures or other issues.
