My Lexon Unox bars arrived for my Mondince FM326 build. I’m happy with both and excited to get this build completed. However, when dry fitting fork, headset and bars I am left with a 2.3mm gap between the head tub and top bearing cover. I have tired every combination of part that came with the frame and bar.
- Bars came with two different compression rings, a plastic and an aluminum.
- Frame came with thee headset bearings each a different height, 7mm, 7.5mm and 8mm.
No matter the combination of c-ring and bearing the top bearing cap is still either too high (gap ranging from 2.3mm or 3.3mm depending bearing heights) or too low (top bearing cap rubbing frame and not engaging c-ring)
With everything I know here are my options that I am aware of:
- Use the combination of 7mm bearing and plastic c-ring (as shown in the above photo), cut the steerer tube accounting for the usual things including headset compression and hope the 2.3mm gap reduces to an acceptable width. I watched a video last night that said to take an extra 2mm of the steerer tub for headset compression so I m being hopeful in this option but still not confident it will get me were I want to be.
- Design and 3D print a c-ring (ABS not PLA) with the appropriate thickness. Easy enough as I have the skills and 3D printer to do so. Not to sure the c-ring will hold up overtime being in compression but is it any worse of an option using the nylon injected molded c-ring it came with?
- Keep researching and see if I can find the proper solution from the Mondince FM326/316 owners on this sub or any others that have have gone through this and have emerged victorious with a safe and proper solution.
Any one gone through this process with this same frame and bar combination or similar situation? Any help would be appreciated. Thank you.
