What happens you feel the need to upsize your 29er. When say, 2.4" wide tyres just aren't cutting it?
Say hello to the Mungo. With clearance for 29" x 3.0" rubber.
The Mungo combines our love of the light weight and exceptional ride quality of titanium with the new 29" x 3.0" Knard tyre from Surly.
Named after Lake Mungo in South Western NSW. The Mungo is the perfect beast for the lakeside terrain. Fat enough for sandy trails (but not too fat), and fast... very very fast.
Important also, the Mungo uses a regular 73mm bottom bracket and 135mm rear end. So no special cranks or hubs required. Just build it up with your regular components and go have some fun.
- now standard with Muru rocker dropouts and belt drive seatstay joiner
- The new ZS44 headtube means that you can run either straight or tapered steerers with ease.
- cable guides for both Rohloff and regular deraileur cable runs.
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 that has the cable stop built in.
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 noticeably 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.
