I’ve ridden both the Mojo HD (in both 140 and 160 guise) and the Nomad C. I’m a big fan of 160mm bikes as your one bike for everything but then I am big full stop and longer travel bikes are just better suited to me.
I like both the Mojo and the Nomad but for different reasons.
The Nomad is the better bike in terms of outright DH performance. The Mojo HD isn’t just a bit shorter in the TT, it’s massively shorter in the wheelbase. I think this is why it’s not quite as capable DH and why it’s also much harder to set the suspension up.
Everyone I know who has one and everyone I’ve read about having one, has struggled to get the suspension working just right – not impossible, but it takes a while. I put it down the very short overall length of the bike. The medium is 1114mm and the large is 1128mm. A large Nomad by comparison is 1143mm (although the medium is close to the Mojo).
For reference, a large Enduro is 1183mm long (as is my tailored Nicolai). That makes a huge difference in terms of balance and stability DH.
The Nomad then works better DH, but the Mojo is more flexible as a one bike solution since you can run it 140mm with a shorter fork and get a very light bike (sub 27lbs should be possible) and it pedals uphill better than the Nomad (at least in my view, although the Nomad also pedals very well.)
The Mojo is also less ‘quirky’ in the way the suspension works; the Nomad’s VPP system is extremely effective, especially over square edge hits and drops but you can ‘feel’ what it’s doing rather than it blending into the background. That robs some trail feedback, but really we’re talking ultra fussy levels of observation here.
Personally I’d take the Nomad over the Mojo and I’d find one that is last year’s model so you don’t have to screw around with your wheels.
Howard at Pedal and Spoke may be able to sort you out with a one year old, light use Nomad C as one of his customers is going to 29″ wheels.
Give him a call on 07706 269 542. I reckon he’s extend you a warranty on that frame as well if you asked nicely.
