The Triple Cross was designed with a slightly racier geometry than the Double Cross. Most notably it uses a lower BB height to enhance handling. While this might keep some of you off more rockier trails, this will help you shine in CX and gravel racing. Though we included fender mounts, we kept the rack mounts off to give it a more minimalistic design.
We were really excited designing with KVA MS2. This air hardening stainless steel is really amazing. The strength and anti-corrosion characteristics of MS2 is really more in the league of titanium than other steel micro-alloys. With MS2 you get the road connected feel that steel is famous for, plus snappy energy transfer without resorting to oversized tubes you need with titanium.

What is KVA MS2 stainless steel?
MS2™ is an air-hardenable, martensitic stainless steel with amazing tensile strength, offering excellent properties, including specific strength and stiffness, toughness and fatigue performance, in addition to corrosion-resistance.
MS2™ stainless steel bike tubing is produced with patented technologies and exhibits:
tensile strength > 200 ksi (1400 MPa)
elongation > 14%
hardness ~ 38-42 HRC
Why should I get this frame? It costs as much as some bargain titanium frames. And more than a custom TrueTemper OXPlatinum frame.
Depends on what you are looking for in a bike...
Bike Snobbery: First off having a stainless steel puts in a pretty small crowd. It is probably the material used the least after magnesium. That is because the material is expensive, hard to get, and difficult to weld. If you own a stainless steel frame, you know it was built by a skilled craftsman, not a robot. Don't get this mixed up with 304 stainless steel use in kitchen utensils. These are state-of-art alloys.
Custom bike: You got us there. Nothing is as having something custom made for, especially if you are hard to fit. Though we have to admit OXPlatimum and 853 are nice riding steel, MS2 is superior in durability and longevity.
Value: Yes if you look hard enough you can find a titanium frame is about the same price. But it usually isn't the nicer tubes and it'll be a bead blasted finish which is notorious for showing scuffs and nicks very easily. We mirror polish our frames, because we like the "shiney". Some custom makers will charge $1000 to polish a ti frame. If you don't need custom sizing, a mirror polish finish and fillet brazed frame for about $2K is not good deal.
Artistry: We can probably look at the lovely stack of dimes welds of a Moots all day long, but we think skinny tubed fillet brazed steel frame has a charm all its own. You can't fillet braze titanium. You can do a skinny tube ti bike, but you wouldn't like the ride.
Why no rack mounts? Is Soma losing its soul?
We consider this a special project and not representational of our core line. We want this to be more of a competition-worthy frame and most racers don't want a full complement of braze-ons on their bike. Against convention, we kept the fender eyelets, because we feel a serious racer should be able to be used for training in the rain. If you really want to add a rack to the Triple Cross, you can by buying a seat clamp with rack mounts on them or get P-clamps.
How do you care for an MS2 stainless steel frame?
General Care Instructions:
- Wipe down dirt, mud, saltwater & grime after long rides with clean cloth.
- A mild soap solution can be used for stubborn road grime; rinse and dry thoroughly.
- After cleaning, to protect luster & finish, apply hi-quality automotive wax or stainless polish with soft, dry cloth and buff out.
- Alternatively, an anti-corrosion surface treatment spray or liquid can be used, Boeshield ® T-9 or equivalent.
Should Any Staining/Spotting Occur:
- Lightly buff with a synthetic textured (Scotchbrite ®) pad or sponge while following the grain direction.
- Use Boeshield® T-9 or similar lubricant while removing stain.
- Use caution if tubes are mirror polished. Use Boeshield® T-9 or another lubricant soaked in a soft cloth and work in small circles.
- Reapply wax, polish or protective coating like Boeshield® T-9 when finished.
Do not use steel wool on MS2™. More detailed info at http://www.kvastainless.com/care-maintenance.html
