FAQS

Can I put a dropper post on my bike?

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

Can I use "Road+" tires on my Stigmata?

Yes, definitely. Road+ (otherwise known as 650x47) will work on pavement or moderate terrain. For rocky or more uneven terrain, we'd recommend something larger to keep the BB a little higher. 27.5x2.0 is better for this use, or something in the 700x35-45c range.

Does the Stigmata work with fenders?

Yes. We designed it to work with up to 700x35 or 27.5x2.0 while using fenders. Tires and fenders vary greatly, so treat these numbers as guidelines, not gospel.

How big of a tire will fit?

The frame and fork will accept up to a 700x45 or 27.5x2.1" tire. The SRAM Red AXS bike will only accept up to 700x42, and no viable 27.5 options, due to clearance limitations with the front derailleur

How many water bottle cages will fit?

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

I rarely take my wheels off, and want a cleaner look.... Can I get wheel axles without handles?

We include Rockshox's excellent Maxle Ultimate axles with the Stigmata, for ease of use. If you want the cleanest setup, use Maxle Stealth or another aftermarket solution. Front axle is 125mm long, 12mm diameter, 12mm thread length, M12X1.50 thread. Rear axle is 174mm long, 12mm diameter, 20mm thread length, M12X1.75 thread

I want to put a different fork on my Stigmata. What specs are important?

Our fork is 395mm axle-crown, so you want to be pretty close to that. We spec 50mm rake on the 49, 52, and 54cm bikes, and 45mm rake on larger sizes.

What brake rotor size is compatible?

The Stigmata uses standard "flat-mount" brake mounts. These are compatible with 140mm or 160mm rotors, depending on the adapter/orientation

What cranks are compatible with the Stigmata?

This bike uses a 68mm threaded BB, so any crank compatible with that standard should work great.

What do I need to mount fenders?

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

What front derailleurs is the Stigmata compatible with?

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.

What kind of headset does this bike use?

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 comes with a compatible headset, whether you're purchasing a frameset or complete bike.

What size chainrings will fit?

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.
