Borroloola 29plus remote tourer
So, you love your dropbars... but you'd like some fatter rubber to roll on. We've heard you... and we've listened.
The Borroloola is intended for those really remote off road touring trips that make for some amazing memories and stories. Think of it as a BNT, on steroids.
The Borroloola brings the comfort of off-road dirt drop-bars to the 29plus wheel category. Combine this with our love of the light weight and exceptional ride quality of titanium with the new range of 29" x 3.0" (29plus) tyres. We took the front end of our popular BNT 29er and merged the back end of the Mungo 29plus. Then we lengthened the back end slightly to make the entire thing ride a little more compliant, for long days in the saddle.
Named after the (very) remote township of Borroloola in the Gulf country of Australia's Northern Territory. The Borroloola is the perfect creature for the Gulf areas rough terrain. Fat enough for sandy trails (but not too fat), and able to be loaded up for remote adventuring.
- a medium (18") frame weighs 1810 grams.
- std rear spacing is 135/142, however 148/Boost is an option by request.
- the 135mm rear hub spacing allows use of regular 135mm or 142mmmm hubs and deraileurs.
- interchangable rocker dropouts mean you can also set the bike up with a 142x12mm rear thru axle or even singlespeed.
- add the Rohloff cable guide kit and Rohloff rocker inserts, and you can also fit the amazing Rohloff 14 speed internally geared hub.
- 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 Borroloola frame has a 73mm (threaded) bottom bracket shell.
- 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.
- "Overlander" geometry designed for long days in the saddle.
- designed around the use of an off-road dirt drop-bar.
- front end geometry is designed around a 483mm axle to crown (rigid) fork or an 100mm travel suspension fork.
- up to 29" x 3.0" tyres (depending on brand)
- our frames carriy a Lifetime warranty. (click the link for the details)
- Seatpost is 27.2mm. The smaller diameter seatpost is a decision that we made to add just a little bit of extra compliance into the ride of the Borroloola.
- now standard with Muru rocker dropouts and belt drive seatstay joiner
- rockers include your choice or inserts. singlespeed, deraileur, Rohloff or 12mm thru axle
- rear upper and lower rack mounts
- two bottle mounts inside the main triangle. One on the downtube and one on the seat tube.
- triple cage mounts under the downtube (in front of the bottom bracket)
- 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
- 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 (or Rohloff as the case may be).
- If running a front deraileur, please ensure that you select a front deraileur with the cable stop built in.
- dual ovalized downtube adds strength and saves weight.
- 3/2.5 titanium seamless tubing is your friend.
- axel to crown is 483mm.
- but really, any fork with clearance for the 29+ tyres and an axle to crown measurement of around 483mm should be fine.
- Polished finish with subtle sanded graphics. Nothing gaudy here.
- scuff it up? get some wet and dry and fix it. No sweat.
- Available in 16" (S) - 18" (M) - 20" (L) - 22" (XL)
Squeezing a 3.0" wide tyre, on a 50mm wide rim, in behind a mtb standard 73mm bottom bracket, is never going to be easy. The chainstays have to be wide to clear the tyre. The BB is only 73mm wide to allow you to use (relatively) normal mtb components and no one wants the chainstays to be super long... So... if you want to run a single ring up front, and you want to use Shimano or SRAM cranks, then you're really limited up front to a 32T ring max'.
(different cranks do have different offsets, if you find one with noticably more offset you might be able to go larger on that front chainring. If you do find a crankset like that, please... share the info and others will sing and dance and honour your name)
If you're thinking of going to a double ring drivetrain... then your options are more... "special". You're going to need a crankset where the chainrings are offset outboard. This kinda limits you to the Surly OD crankset. The new Boost cranks that Sram, Race Face and others are releasing this season may offer more options for double chainring combinations.
