Bash guards are great for protection and can still be used with the Derailleur-Guide.

Actually, If you look at the 10th picture (the rear view) or any of the pictures if you look hard enough, you can see that the guides sit in groove and have a spring and cable attached to them so that they do, in fact, become further apart when shifting into the larger gear and closer together when shifting to the smaller gear.

I played around a little bit with weight optimization and removed some excess material in non load bearing areas. Using FEA, the changes I made will not affect the structural integrity of the derailleur-guide. I got it down to 190 grams, but still believe it has much room for improvement. This would make it lighter than any standard chainguide from Straitline, DRM, e13, etc.

I have not heard of the TRS+ before, but from what I can find it does not have the ability to shift. On the derailleur-guide the cable attaches on the linkage (the black piece connecting the two rollers) close to where the return spring attaches. If you look through the pictures, you will see that the derailleur-guide does not just move in and out, but the guides that the chain go through will get farther apart when in the larger ring and closer together in the smaller ring (hence the springs on the guides and the cables attaching them to the rollers) Also, the shifting is more complex than just moving in and out, the rollers make it so that the top of the chain shifts first (overshifting slightly so that the chain will catch) then the bottom part of the derailleur-guide will swing out after the chain has had a chance to catch and fully shift onto the other ring. As it is designed right now, the projected weight is around 250g. I misspoke before, I meant to say that the weight is slightly more than a chainguide, but much less than any combination of chainguide and derailleur. Also, the version submitted is not optimized for weight and I am sure that there is 30-50g that can be cut without affecting the strength of the part.

Keeping the chain in place is a simple task until you decide you want to be able to change gears. There is not a product on the market that can stabilize the chain in the horizontal and vertical direction both above the chainring and below it unless you are satisfied with running just one chainring. With the derailleur guide you can do stabilize the chain while running two chainrings. XX and XRT derailleurs do not have the ability to guide the chain on the underside of the chainring. This means that any vibrations carried through the bottom of the chain will be able to make the chain skip, jump, or fall off. Bashrings are great, but they only prevent the chain from falling out of the top gear, they do not prevent the chain from skipping, unwanted shifting, or falling off the smaller chainring. The Derailleur-Guide combines a chain guide with a derailleur, making it incredibly difficult for the chain to fall off, skip, etc. but also allows you to shift between two chainrings. It weighs about the same as a SRAM XX front derailleur and less than a Straightline Chain Guard.

Hi everyone, here is a link to some more images of the derailleur-guide, including some exploded views and how it looks on a bike http://carrottop596.pinkbike.com/album/Reality-Redesigned/ . Let me know if you have any questions and I will try my best to answer them.
