The Tor Abrade Synchro Build

2021 was a bit grim for drivetrains! The combination of a global component shortage and higher than average rainfall meant chains, cassettes, sprockets and pulleys were being consumed well past their use by date. “Have you got an XT Derailleur?” was the question sending a shudder down the spine bike shop staff around the nation. That got us thinking…

Q- What can be done?

A-Ditch the conventional drivetrain!

The Drivetrain

The Tor Abrade Synchro is a progression of the Abrade hardtail. An aggressive hardtail with modern geometry coupled with a low maintenance and robust Pinion C1.12 gearbox and Carbon Gates belt drive. Nothing to lubricate, no hanger to bend, no cage to twist and beautifully smooth shifting. The C1.12 also offers a massive 600% range which is significant when compared to a regular 12 speed Sram or Shimano drivetrain.


The TIG welded frame is constructed of a combination of Columbus Zona butted steel tubing and straight gauge 4130 steel tubing. Stainless steel horizontal dropouts allow for accurate belt tensioning and interchangeable sliding dropouts . Fully external cable and hose routing with the exception of the dropper post cable.

The finish on this frame is as impressive as the drivetrain. Mitch at 74Works  created this tri-coloured scheme from H-series Cerakote ceramic coating. Cerakote is an ultra thin and extremely durable industrial coating typically used in automotive, aerospace and military applications. Perfect for mountain bikes! Unlike paint, Cerakote can’t be fully cured between colour changes so must be handled hot and completed in one go. Mitch is meticulous with his work and planned this one out in detail before picking up the gun. This stunning finish is the result.


The geometry on this bike has been custom designed for a customer who rides a medium dual suspension trail bike. The smaller cockpit allowed for a BMX or DJ bike inspired straight line from the headtube to dropouts through the top tube and seat stays. This feature may require a seat tube brace on larger frames.
