The new Mk4 Audax builds on over 30 years of producing Audax bikes, its been bought up to date with provision for an ISO disc and appropriate cable routing. Though its still able to take traditional calliper brakes, down tube gear levers, STI’s or bar end shifters as you wish!

Frame accepts 28.6mm clamp-on front derailleur, deep-drop 47/57mm Allen key fitting brakes, rear OLN 135mm. Frame will take 32c Schwalbe Supreme tyre with mudguards, 35’s when run with a disc and no guards.

Thorn 858 double butted seamless custom Cro-Mo tube very similar in composition to Reynolds 725, two sets of bosses on rear triangle for racks or mudguards, down-tube bosses accept either stops or Shimano down-tube levers but not Campagnolo.

New for 2019 is a custom rear dropout, this incorporates an ISO disc mount and clearance for a 140 or 160mm brake rotor.

The frame has an anchor point for a “Rohloff Axle Plate OEM2 Adapter for M5 Fender/Luggage Rack Bolt – 8552” meaning a Rohloff hub with an OEM2 axle plate can be fitted, however you will still need a chain tensioner and split able drop handlebars like the Van Nicholas bars (SJSC#46824)

Each frame supplied with FREE Thorn 30mm Layback seat post and FSA Orbit XLII Headset prefitted.

I recommend this product
Bought this frame with Thorn's matching 858 fork to build up myself. Still early days but it's a lively and responsive ride, without sacrificing comfort. I went for calliper brakes all round but the frame has rear fittings for a disc brake, if that's your thing.
