Comments & Questions

OPEN
I like this spec. I can't see the XTR FD on the picture, but it's listed in the spec.
Are there any challenges setting up Shimano XTR Di2 FD on this frame? Any issues with with the Shimano R785 Di2 and XTR derailleurs getting along?

I was thinking of going with a 1x, but if the XTR FD works then I'll go this route.

I just saw the other post with more pics. No XTR FD... but would it work on this frame or would it rub the chain?

Hi Carl, sorry for the confusion, we use a standard cell field called "front & rear derailleur". Fixed now. There is no front derailleur as you note, and you can't use one in combination with the XTR rear derailleur either. You can shift XTR Di2 derailleurs with the Shimano Di2 road shifters, but the front and rear derailleur have to be of the same "family" (either both road or both mtb groups).

So you can shift XTR front and rear derailleurs with road shifters, but the front XTR derailleur won't fit on the frame. And if you replace it with a DuraAce or Ultegra Di2 front derailleur, that one will fit on the frame but to piss everybody off, Shimano has programmed their group such that the road shifter will refuse to work, because the front and rear derailleur don't belong to the same family. No technical reason for this, just a big company being unhelpful to consumers wanting to build up bikes for the maximum amount of fun.

I would be interested if you can elaborate on the gear ratio choice, especially seeing that the photo does not indicate a front derailleur. This seems like a "mountain" setup and not general ratio.

Hi Leon, 1x is probably the most popular set-up on the U.P., and the SRAM Force 1 group the most popular among those. You can find more about how to think about the best 1x gear ratio here: https://opencyc...train

Nerd question: Looks beautiful and comfortable, but how many watts would you loose on "tire street drag"; love the concept of the bikes but I don't ride that much gravel and many our group rides are fast and this much tire friction may make me pop off the back or is it negligible??

Well, if you're on the road, put on road tires. Then switch for off-road (switch out either the tire or the wheelset). Right now I have 30mm WTB Exposure tires on my 700c wheels, smooth ride, great comfort due to the slightly bigger tire. but of course you could also do that with 25 or 28mm tires if you prefer. And then my second set of tires right now has 2.1" Racing Ralphs on them, although I have also had them with 47mm Horizon Road Plus tires. The possibilities are endless.

All that said, even with the mountain bike tires (and definitely with small-knobbed cross tires), the bike is still fast. Mountain bikes are slow on asphalt not so much because of the tires, but because of the rider position. But of course with a smooth tire they are even faster.

You are awesome Gerard. Looking forward to doing exactly what you said.

Just to make sure that was clear, the 2.1" mtb tires or 47mm RoadPlus tires would be on 650b wheels. For 700c wheels you would go with something like a Nano 40c tire (which is what I rode during the summer before I mounted the Exposures. As you see, the possibilities really are endless.

Great build!
I wonder if 36t is enough for road-riding?
Can I customize a Di2 1x drive in a way that I shift left up and rightside down i.e. eTap style?
Thank you!

Yes, you can, you can program the buttons any way you want. And of course, if where you live 36t is not enough, you can go to 11-40, 10-42, 11-46, whatever you wish. See for example the May 2016 Bike Of The Month here: https://opencyc...16/05

Hey - I just got one of the 3T models of this bike. Regarding cranks - I have an XTR 980 laying around with a stages power meter on it. I am pretty sure if a road crank clears then a mountain crank with a stages will? The second question is - are you aware of anyone that makes a larger 94 mm 1x chain ring. I would like to run a 40 or 42 tooth but there is nothing that I can find out there to fit the 980 crank.

Hi Doug, there is no 3T model of this bike. 3T also makes a GravelPlus bike, the Exploro, but all questions about that bike are best addressed directly to 3T.
