TRACKA

GRAVEL

Expand your riding options. The Tracka is my ideal gravel bike design and it's made to be fun, fast and capable on paved and gravel surfaces.

High-end frame tubing is used and here I choose smaller diameter tubes with slightly less stiffness. When paired with the large supple tyres the combination makes for greater comfort and more surefooted cornering 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 enable the use of these larger width tyres and offer powerful consistent braking in all weather and road conditions. I can now offer frame and fork to fit wide tyres from 42 to 50mm depending on the crank and fork which are listed below. See the complete bike detail below for the maximum tyre size which each drivetrain can fit. 

The rear brake hose can be routed externally for ease of maintenance (your bike mechanic will love you) or internally for a cleaner look with the rear brake hose entering the downtube near the fork and exiting the frame near the rear brake caliper.

The frames are paired with carbon-fibre forks chosen to compliment the frame. The Futura Gravel fork has clearance for 40mm measured width tyres and its 1-1/4" tapered steerer will be less stiff and hence more suited to this style of bike than the more common 1-1/2" tapered steerer.

The newly released Futura Cross fork offered by Columbus has more tyre clearance, with room for 47mm measured width tyres and comes with the stiffer 1-1/2" tapered steerer. The Futura Cross+ fork comes with rack mounts.

The ENVE G Series Gravel fork offers the greatest clearance for with room for 50mm measured width tyres on 700C rims, and 57mm on 650B/27.5" rims. It comes with the stiffer 1-1/2" tapered steerer.

FEATURES

  • 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 1-1/2" taper fork steerers. 

  • 12mm thru rear dropouts in 142mm spacing. 

  • Flat mount disc brakes with the caliper neatly tucked between the rear stays.

  • Sloping toptube with healthy amount of seatpost extension to reduce the impact from bumps for a smoother ride.

  • Standard 27.2mm seatpost which suits almost all riders and being slender, gives a supple ride. Larger riders get a 30.6mm post. A DKG brand seatpost clamp is supplied with the frame.

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.

  • Ultegra 2X Di2 disc max 42mm tyre; R8070 $8970**

** Custom DT Swiss wheelset; this is my preferred wheel spec. I believe it is superior to most other designs in terms of bang-for-your-buck aluminium rim wheels.

Hub: DT350, Centerlock rotors,

Rims; DT RR421 DB  disc-specific tubeless-ready rims with an asymmetric rim shape for improved spoke angle and hence wheel durability. The sidewalls of these rims have far less material since they are not a braking wear surface.

Spokes: DT Comp butted spokes in black finish. Butted spokes are more durable AND a lower weight.

Nipples; DT's Squorx alloy nipples in silver finish with Pro Lock (to prevent loosening) with PHR washers (for much increased surface area).
