Witjira overlander fatbike frame - (AUD) $1899

The Witjira is the end result of countless klms ridden on varied terrain. Sand, snow, singletrack, fireroads and some very long days in the saddle.



The Witjira was the original model in our range. As the frame that started Muru on our way, the Witjira has a special place in our hearts. It's also very versitile. The 170mm rear spacing also lends itself to the new Rohloff XL rear internally geared hub. As the original frame in our "Overlander" range, the Witjira is most at home on remote beaches, outback trails, and tracks.

 

Named after Witjira National Park in Central Australia and designed to deal with all terrain. Proven on the real world of the Iditarod Trail Invitational in Alaska and the Simpson Desert Bike Challenge in Australia.



FEATURES:

 

Weight

- a medium (18") "std" frame weighs a genuine 1700 grams.  

- add rockers, Rohloff guides and belt drive joiner and you add around 125g.

 

Rear spacing

- the 170mm rear hub spacing allows use of regular 170mm hubs and deraileurs.

- add interchangable rocker dropouts and you can also set the bike up with a 177 x 12mm rear thru axle or even singlespeed.

- add the Rohloff cable guide kit and Rohloff rocker inserts, and you can also fit the amazing Rohloff XL 14 speed internally geared hub.

 

Bottom bracket

- all our frames use a reliable, time proven BSA threaded bottom bracket. We've elected to steer clear of the dozen or more press-fit "standards". Almost all of which are known to creak under load.  The Witjira and Tanami frames all have a 100mm (threaded) bottom bracket shell.

 

Headtube

- our 44mm headtube means that you can run either straight or tapered steerers with ease.

- want to run a straight steerer fork? Then you'll want a ZS44/28.6 upper and ZS44/30 lower.

- want to go tapered? then you'll want a ZS44/28.6 upper and an EC44/40 lower.

 

Geometry

- "Overlander" geometry designed for long days in the saddle.

- front end geometry is designed around a 465mm axle to crown (rigid) fork.

- single ring front -  up to 4.5" tyres on 80mm rims. (4.8" depending on cranks and chainline)

- new "Troy Cage" mounts in front of the seatpost on top of the top tube allows you to run an accessable bottle cage while also running a full frame bag

 

Cable guides

 - All Muru frames use "open" cable guides.

- This means that there are no cable "stops" at any point on the frame.

- This allows you to run full housing all the way from the shifters to the deraileurs.

Frame features

Recommended fork

- axel to crown is 465mm. We've designed this frame around the use of a rigid fork.

- we recommend our own Swale Overlander ti or the Dice Mr Sooty carbon, though any fork with an axle to crown measurement of around 465mm should be fine.

 

Finish

- scuff it up? get some wet and dry and fix it. No sweat.
