trade off of electronic shifting and 2x.

as for the clean lines, I want a 2x but love the look of 1x. torture!!! hahah

nice documented thread. makes the RDO more attractive, but also pushes me more towards Norco Search XR.
yeah I read through the "I don't want an adventure bike" topic too. but I do, but I don't. but I want a higher BB. but the Norco isn't much higher 73 vs 75.

regardless nice thread, I''ll probably re read through it a couple more times.

Nice detailed post. Thanks for sharing!

I'm currently building the same but with a Force 1x setup - 50T on the front and 11-42 rear - its going to be interesting.

Are you still happy with it?

I'm very happy with it.

Killer looks - MTB guys say, "that thing looks badass."

Stellar performance. I can't even begin to push this bike to what it is capable of.

There are a few 1x setups out there. Looking forward to seeing yours!

This is how it looks cross chained big/big, 50 front and 36 rear...




It seems to shift fine but my main concern right now is the B screw and how it interfaces with the derailleur hanger. The photo below was previously posted but it illustrates the angle at which the screw contacts the hanger. The further the screw is turned in, the more acute the angle until eventually the screw simply falls off the edge of the hanger.



The pulley doesn't contact the big sprocket but the screw is barely touching the hangar and I'm not happy with the amount of metal it has to push against. Not sure what the solution is, or if there is a solution, or if I'm just being retentive.

A photo of how it sits now will have to wait until the wheel comes off.

Didn't see a solution posted but if you flip the screw around the head will make more contact with hanger tab. You can also swap with an m4 Allen head bolt installed reverse as well

Swapping the stock bolt for a hex bolt is a brilliant idea!

The stock bolt is working for now but it is at the edge of its adjustment. Your solution is on my to-do list, probably when I replace pads and bleed the brakes next.

The tool is the yellow part in the photo below and it told me what I already knew; the bolts supplied with the calipers were too short. The photo below shows how the correct length bolt is supposed to look with just the tip visible in the pocket of the tool.



A chart in the documentation is much more useful than the tool, especially when calipers are available. The Niner chainstays are 30 mm and the bolts in the brake kit fell short by 5 mm. The chart even gives the Shimano part number.



$11 and a four day wait brought two Shimano BR5121, 43 mm flat mount caliper bolts to the doorstep. These mounted head down through the chainstay and screwed into the underside of the adapter plate. Again, a dab of grease was applied to the threads. Note the alloy washers between the bolt head and chainstay - Shimano calls these out as a necessity. Finally, a retention clip goes onto the end of the rear mounting bolt.

Tim,

All links to photos are gone... I'm building up an RDO frame and re-discovered this thread and now want to learn from your build... I too will be running 160mm rotors front and rear with R8070 calipers and know I'll need a mounting adaptor but it looks like I'm going to have to purchase longer fixing bolts as well? Anything else I should be aware of?

I see all the photos no problem. Are you on a MAC? Some on MACs have reported problems seeing the images.

If you use the adapter in the rear then you will need longer bolts. IIRC they were sourced from Modern Bike.

Really nothing else to it. Just use the adapter, get the longer bolts and put it together.

Good luck.
