Hi Hubbers I recently took on a (fun) personal project of finding an alternative to the commercially available cover plates used to cover up the frame mounting space left when removing the high direct mount front derailleur for a 1x conversion. After searching the interwebs I cottoned onto a 3D printed plate through options and ideas from Shapeways and the MTBR forums. Shipping for the Shapeways product made it unreasonably expensive for what it is ($6 for the plastic plate, $20 for shipping), so I contacted a few 3D printing companies in Cape Town to see if someone could help me out. And success! I managed to find someone! Following a bit of trial and error with my design I ended up with a plate that I am pretty stoked with!! I have customised it for my Pyga and I think it looks pretty rad! The finish of a 3D print is not the smoothest, but it's hardly noticeable when viewed from a short distance. Best part is it cost a fraction of anything else out there, amped Thoughts on the outcome are welcome and I'm happy to try help anyone out who would be interested in doing the same for their 1x conversion. By this I mean I can either share my 3D file with you (if you can access a 3D printer) or look at getting plates printed through my own source (limited to black or white) and then take it from there. I assume the design would be a universal fit, but have only managed to test it out on the Pyga frame so far. Given that it is also a very recent addition to my bike I have no idea of durability of the part and how it will stand up to the elements (it's made from ABS plastic) but will post future updates here. Fingers crossed it will have some longevity! Overall though I think the project was a success, win!

Anybody knows where I can source a cover plate for a front derailleur (direct mount)??

I have a direct mount front derailleur on my TT bike and at the moment I have a non-round ring running 52 teeth. This BARELY fits at the point of maximum adjusted diameter... (relatively 54/55 teeth). Problem: I want a bigger front chainring... and it will be non-round. It's a personal preference based on my knees, hips, crank lengths, experience, marketing hype and placebo effect... So no opinions on this - thanks. None of the non-rounds fit - and I believe I need an adjuster like the images. This spacer moves the FD backwards, and thus I can get a bigger blade on. I can find some online in the UK but for GBP30... plus shipping, postal inefficiencies etc... I have contacted Rotor directly for the part - no reply yet, but I fear this part may be near R1,000. Any alternative or 'Ghetto' solutions?

What is the main differences between these front derailleurs and when to use which? Current bike has a top swing on it - will a bottom swing FD work?
