The Terra is a progressive geometry mountainbike designed for fast rolling trails whilst still able to negotiate tight uphill corners.  

Clearance for up to 27.5 x 2.6" tyre is possible with a 1X Boost drivetrain and with these tyres the bike is heaps of fun and yet still fast. Thru axle rear dropouts are standard in 142x12mm or 148mm "Boost" width. Your frame can be constructed of Rugged, Race or Ultralight tubing according to your riding. Custom geometry can range from Enduro to Trail or Race.  A dropper post option with external or internal routing is available. 


  • custom frame tube selection to suit you

  • thru axle in 142 x 12mm or Boost spacing, 148 x12mm 

  • clearance for 27.5 x 2.6" tyres with Boost drivetrain, 2.4" tyres with standard.

  • rear disc Post-Mounts between the seat and chain stays to suit 160mm rotor.

  • standard 27.2mm seatpost sizing to take the edge off bumps with a desirable amount of flex.

  • threaded 73mm wide bottom bracket in the new large T47 standard or classic "English" format for quiet trouble-free operation, The larger T47  enables internal routing of cables when used with 24mm crank axles. 

I use White Industries and Chris King headsets both of which are available in a range of colours as well as Black. White Industries machine their parts to use the excellent replaceable Enduro Bearings while Chris King built their reputation on making their own bearings which are serviceable. Depending on the fork, the Chris King headset is an approximate $50 upgrade. 


Frames from $3300 with 12mm thru rear dropouts, "between stays" post-mount disc brakes, custom selection of Columbus Zona and Life butted frame tubing.

Framesets from $4400 with RockShox Reba fork, White Industries headset and Shimano PRO LT stem paint-matched to the frame and PRO LT seatpost. Minus pedals and saddle.
