This is a bit of a silly question, but does anyone know what chainstay protector Why Cycles is using on their R+? I recently did a pretty gnarly rocky trail, and my chain kept striking the chainstay (I really wish they made a Di2 rear derailleur with a clutch system)... I don't really like the one Moots sells, and don't want to use an old tube or any of the cloth protectors, as I think they look bad. This is the one I'm referring to:

They do. XT and XTR Di2 rear derailleurs have clutches, and you can run them with the Di2 road shifters. If you have a front derailleur you'll have to change that to XT or XTR as well.

Yes, I should have clarified, Di2 road group with a clutch derailleur, I just bought this stuff and don't really feel like buying both front and rear again.

A LOT of people are using 3M's Mastic Tape. It's inexpensive, super protective, and easy to work with (cut to shape, stretch, etc). I would not be surprised if something similar is what's in that picture.

Thanks for the suggestions, I had never heard of Mastic tape. I've used helicopter tape on other bikes, its fine, but seems to get worn through quite easily. I've also used similar things to the frame guard "stickers" and they work well enough for rock strikes, but they always seem to fail in the same way helicopter tape does on the chainstay, due to the repetition of strikes that the chain causes. I guess I'll try the mastic tape next, see if its any better at continuous strikes.

Cheers!

I feel like I have seen carbon fiber tape of some sort before, but can't remember where and have not heard how well it works. With that said email Adam at Why Cycles and ask him what the used on the R+.

Oh, it is.

You gotta stretch it a bit for better adhesion. Mine hasn't budged after two CX season and there's no tears/holes/etc. I have also snuck some tiny pieces in where the rear rotor can bump the frame during wheel changes because of how quickly 'helicopter tape' shreds.

Not sure if anyone would be interested in doing this to their frame, but you could go to a Rhino Lining business (truck bed spray on liner) and have them rhino line the stay. Wouldn't recommend this for carbon, but would work well for steel or aluminum. My brother-in-law has done some other parts on bikes and it worked well.

This stuff seems to work brilliantly, I went over some rough stuff, jumped off some things, and did some vigorous reverse pedaling, and not once did I hear the chain hit the frame. It for sure handles multiple strikes, now I just need to work on shaping it a bit better (maybe next time), cause its not the prettiest job I've ever done.
