How Orient Rethinks the 1x Drivetrain: Blackwater and Marginal Gain’s Concept

Orient is a Blackwater and Marginal Gain drivetrain concept intended to keep the chain straighter across a cassette. It was shown on a Splitfire, but production and performance are not established.

Orient is an early drivetrain concept from Blackwater Bicycles and Colorado’s Marginal Gain that focuses on how the chain tracks across a cassette, rather than simply adding cassette cogs or making a rear derailleur more complex. The concept was shown on a Blackwater Splitfire at the CRAFTED Bike Show; it is not established as a production component.

What is Orient, and where was it shown?

Bikerumor’s Jordan Villella reported on Oct. 5, 2026, that Blackwater Bicycles displayed a Splitfire gravel bike fitted with the Orient concept at CRAFTED, the show hosted at Cane Creek Cycling Components on Sept. 26–27, 2026. Bikerumor’s report identifies Marginal Gain, a Colorado company, as Blackwater’s collaborator on the drivetrain idea. The official CRAFTED event page lists the inaugural show dates and venue.

The Splitfire is the display platform, not evidence that Orient is available on a retail bike. Blackwater describes the Splitfire as a titanium gravel bike and lists 700 x 57 mm tire clearance and chainring clearance figures on its official product page; that page does not list Orient as a production option or confirm a retail build equipped with it.

How does Orient aim to change a 1x drivetrain?

In a 1x drivetrain, one chainring drives the chain across multiple rear cassette cogs. As the chain moves toward either end of the cassette, it runs at a more angled line relative to the chainring. Orient’s stated design intent is to keep the chain straighter across more of the cassette and reduce chain articulation.

  • 【Groupset】Contains 10 speed chain, 10 speed 11-50t cassette, 1x10 speed rear derailleur and shifter. Suitable for 1x 10 speed mountain bike.
  • 【Cassette】10 speed 11-50t cassette. Cassette cogs: 11-13-15-17-21-24-30-36-42-50T; weight: 541g.
  • 【Chain】10 speed chain with missing links. Links: 116 links; size: 1/2" X 11/128"; weight: 264g.
  • 【Shifter】10 speed aluminum shifter. 1:1-Tech makes quick and precise shifting perfomance; weight: 120g.
  • 【Rear Derailleur】10 speed rear derailleur. Maximum compatible sprockets: 50T; weight: 295g.

The rationale is that extreme chain angles in wide-range 1x setups can contribute to friction, wear, and efficiency losses. Those are the motivation for the concept, not results demonstrated for Orient: the cited reporting provides no measured efficiency gains or comparative wear data.

Could Orient support 15- or 16-speed drivetrains?

Marginal Gain believes the concept could make 15- or 16-speed arrangements possible with more reasonable chain angles, according to the Bikerumor report. This is a company-stated possibility, not a confirmed speed specification, tested capability, or production configuration.

What is known—and what remains unproven?

Question What the available sources establish
Design goal Orient aims to keep the chain straighter across more of the cassette and reduce articulation. Bikerumor
Efficiency and wear No measured efficiency gain or comparative chain-wear result is reported. Blackwater representative Billy Hudgens said testing of wear at transition points was ongoing; no outcome is given. Bikerumor report; Hudgens’s comment
Speed range Marginal Gain’s possible 15- or 16-speed use is an attributed claim, not a demonstrated specification. Bikerumor
Compatibility and final specifications Not stated in the cited sources.
Weight, production timing, and retail price Not stated in the cited sources.

Hudgens wrote: “We are currently testing the wear on the ‘shift points’ and may use other materials and replaceable parts in those locations if it is excessive.” That comment describes ongoing maker testing, not a published durability result.

For riders, the distinction matters: a promising chainline concept is not yet evidence that a drivetrain will be more efficient, last longer, fit a particular frame or component group, or be available to buy.
