Post Mount Disc Tab Fixture
Please note that prices listed are in Canadian Dollars. $125 Canadian converts to approximately $96 American.
The fixture is for attaching bicycle industry Post Mount standard tabs. This is the standard found on many bicycle frames and forks. It allows you to run Post Mount disc brake calipers. You can also attach ISO tabs with this fixture, using the appropriate adapter.
The two pairs of mounting holes are 74.2mm apart, and in the correct position relative to the axle as per bicycle industry standards. With the fixture in FRONT mode(with included spacer), a disc tab can be attached to a fork. With the fixture in REAR mode(with included spacer), a disc tab can be attached to a frame. Any standard Post Mount tab may be used, and may be purchased from other suppliers or made by the framebuilder.
Photos of installations can be seen on the Incepi Instagram page.
Useful for mechanics and shops
The fixture is also useful for bicycle mechanics and others in the bicycle industry. It can be used to verify whether disc tabs already attached to frames or forks are misaligned or improperly positioned.
Simple to use
The installation process is exactly the same for the fork and the frame.
Secure the dummy axle into the dropout, with fixture attached. Install the tab into the fixture. Rotate the fixture until the tab is in the desired location. Decide on the cut line for the tab that will best match the profile of the frame or fork. If you want to experiment before cutting the metal tab, you can trace it onto cardboard and modify the cardboard cutout first. Once you are satisfied with the fit, you can cut the metal tab using the profile of the cardboard mock up.
Trace the contour of the frame or fork onto the tab. Remove the tab and machine, cut and file as required. Reinstall the modified tab onto the fixture. Weld or braze the tab onto the frame or fork.
Detailed instructions will be provided with every fixture.
Risks and challenges
There is very little risk involved with the manufacturing of these parts.They are made with conventional machining processes. Well established local machine shops have already quoted the parts. I have worked with these shops successfully on other projects. These are local shops that have successfully delivered in the past. On time and on budget.
The parts are proven to work. Post Mount disc tabs were attached using the prototype. Photos are available here: instagram.com/incepibicycle/
This is the same fixture which will be provided to project supporters. No further revisions or enhancements are required.
The only real risks involved are manufacturing delays due to machine shop scheduling conflicts or errors. Supporters will be updated about delays in a timely manner. I have provided access to the project details to somebody familiar with the project in the event that some unfortunate event should prevent me from completing the project personally. The original Incepi ISO fixtures were delivered as promised to Kickstarter backers. Incepi Flat Mount fixtures were also delivered on time and on budget. The Incepi Post Mount fixtures will be delivered as promised.Learn about accountability on Kickstarter
