Stigmata 4 MY25

The Stigmata does not have rack mounts, so we would recommend a rack that uses the wheel axle to fit a rack. Old Man Mountain makes some options that will work.

Our fork is 430mm axle-crown with a 45mm offset, so you want to be pretty close to that. If you're looking to put a suspension fork on, the Fox 32TC or Rockshox Rudy with 40mm travel are what we recommend

The Stigmata 4 is built specifically for 700c wheels and tires. We don't recommend 27.5.

The Stigmata uses 160mm "flat-mount" brake mounts. These are compatible with 160mm or 180mm rotors, depending on the adapter/orientation

With 1x, you can use up to 42t. For 2x, we've built it to accept up to a 36t small ring and 50t big ring

This bike uses a 68mm threaded BB, and is specifically designed to accommodate SRAM Wide cranksets or Shimano GRX. These cranks have greater chainring-frame clearance than older road cranks and will provide the most room for whatever chainrings you wish to use.

Bikes and frames include the custom seatstay mount that we designed, as there is no traditional seatstay bridge on the Stigmata. Other than that, you should only need the hardware that comes with your fenders.

The Stigmata has mounts for 3 bottles. One is under the downtube, and the other two are inside the front triangle.

Yes. We designed it to work with up to 700x45mm while using fenders. Tires and fenders vary greatly, so treat these numbers as guidelines, not gospel.

Yes! We've included options for routing internally-routed dropper posts on the Stigmata. Just make sure you order a 27.2mm post

We've built this bike to accept electronic FDs, or modern cable-actuated FD's from Shimano (7000/8000/9000 series). Mechanical FDs from SRAM won't work, as they lack the integrated housing stop that's necessary with our cable routing. The FD mount is included with all Stigmata bikes/frames and mounts a braze-on FD to the seattube.

The frame and fork will accept up to a 700x50mm tire. Bikes with front derailleurs are recommended with a Max 45mm tire due to tire-FD clearance.

Currently all technical info is located either on the product support or tech support sections of our website. Both can provide helpful information for puzzling with your bike, torque specs, and exploded diagrams.

This bike uses integrated headset cups. The upper is 41mm and the lower is 52mm. The SHIS name is IS 41/28.6 IS 52/40. The fork uses an integrated 1.5" crown race, with a 36* taper angle. We know that's a lot of specs to worry about, so we made sure that every Stigmata/Quincy comes with a compatible headset, whether you're purchasing a frameset or complete bike.
