Gravel Bike

This Force/Ultegra level Gravel Road disc-brake bike is fast and capable on paved and gravel surfaces. It was exhibited at the Handmade Bicycle Show Australia 2018. The tyres, forks and drivetrains that have become available offer the greatest choice ever to create this style of bike. This is my current ideal build and being custom made it could also be re-imagined as a completely different build.

Expand your riding options, with greater comfort and traction than a traditional road bike. The large supple tyres now available are fast too. Every frame is customised to the rider, both the riding position and frame rigidity so you have the far more choice of comfort than a typically overly-stiff mass-produced frame. 

Disc brakes are preferred here for their powerful consistent braking in all weather and road conditions and enable use tyres, up to 40mm measured width. My current favourite is the 38mm wide Schwalbe G-One Allround. 


  • Stable geometry and a range of frame suppleness options with the choice of Double-Oversize,  Oversize, or Not-Oversize (NOS) frame tubing.

  • 44mm head tube compatible with 1-1/4" or 1.5" taper fork steerers.

  • Replaceable derailleur hanger,

  • Flat mount disc braking, for tidy discrete calipers.

  • Sloping toptube with healthy amount of seatpost extension for a smoother ride.
