Peacemaker Gravel Framesets

Bottom Bracket

The Peacemaker uses an English threaded BSA bottom bracket (68mm) - you're welcome. It is compatible with SRAM GXP, Easton/RaceFace BSA 30 and other Shimano and compatible bottom brackets/cranksets. Due to the myriad of bottom bracket standards and some cross compatibility, make certain you use a compatible combination. 

A standard SRAM GXP BB uses no spacers.

Headset

The Peacemaker uses a 42/52 integrated headset. It comes stock with either a lower Chris King crown race/bearing mated with a Cane Creek upper or a complete Cane Creek assembly. There are no additional cups to press into the frame.

Note: The Peacemaker is not compatible with the Chris King DropSet upper bearing/assembly due to the height of the bearing - bummer, we know but it's actually not that uncommon of a thing. It requires a shallow upper bearing height. 

Cane Creek 40 and 110 upper bearing assembly's are recommended. 

Drivetrain

The Peacemaker is compatible as either a 1x or 2x drivetrain setup. To convert to a 1x setup simply remove the front derailleur mount with an Allen key.

If you feel the need: To remove the coned cable guide behind the seat tube, reach in through the bottom bracket opening and gently, but with a bit of force push out while using your other hand to wiggle the exposed cone to work it out. 

Do not use a screwdriver or other metal tool to pry the plastic cone as you may damage the frame. Meaning, you will damage the frame and then we'll hate you.

Seatpost

The Peacemaker uses a 27.2 seat post and like a much bigger brand whose name begins with a G and ends with a T, our frames are designed around the use of an offset seatpost. However, if you're the long legged/super short torso type then you may want to forget all that and go with a zero offset post. Don't worry, we're not super opinionated about seatpost offset. Bar tape though, that's another story.

We recommend using a carbon post over an aluminum post if possible due to negative reaction that can result from the two materials reacting over time. To negate post seizure inside the frame, apply a liberal amount of grease starting an inch below the bottom of the seat post collar. Around the inside of the seat tube underneath the seat collar apply carbon fiber paste to keep the post from slipping under weight.

If using an aluminum seat post on any carbon bike, you should remove it from the frame periodically to avoid having it seize inside the carbon frame. 

Disc Brakes

The Peacemaker uses Flat Mount disc brakes. The rear chainstay thickness is 25mm and uses 32mm button head bolts. The front uses standard 15mm button head bolts.

SRAM 15mm Part No.: 00.5318.005.002

SRAM 32mm Part No.: 00.5318.005.006

To run 160mm rotors front and rear, you'll need the following flat mount adaptors:

SRAM Front Part No.: 00.5318.018.000

NOTE: You will need the above adaptor for both 140/160 Front Rotors

SRAM Rear Part No.: 00.5318.018.001

Internal Cable Routing

The Peacemaker uses internal cable routing for both the brakes and derailleurs. The rear brake hose is routed through the center port at the head tube and over the bottom bracket shell. It exits out the inside of the non-drive side chainstay and is held in place with the included plastic clip. The front brake hose is routed through the fork. Both the front and rear derailleur cables are routed underneath the bottom bracket and through the removeable cable guide hidden beneath the cover under the bottom bracket. The front derailleur cable uses the upper port on the head tube and the rear derailleur cable uses the bottom port. 

It is recommended that you use a padded housing cover over the rear brake hose in the downtube to reduce any rattling noise. If your LBS doesn't stock the foam tubing there are a number of hacks that work just as well. One of my favorites was using an old shoe lace that when squeezed was tube shaped and easily slipped over the brake hose. Another hack is to tie a bunch of zip ties at various angles around the brake hose and not cut off the excess - the ties then press against the inside of the downtube at various angles/points. Not the cleanest option, but we've heard it works.

Update: We are in the process of sourcing Jagwire Housing Damping Foam to include with future framesets. However, it is unavailable until sometime in mid-September 2019. In the meantime, if you'd like to search out your own: Manufacturer Part #ZSK600 / UPC 4715910039472.
