Review: Scott Genius 900 Tuned

Scott’s ‘Any Trail, Any Time’ promise is a bold one to bandy about, but, with the right setup, the Genius is impressive!

The Scott Genius 900 Tuned – a special order only item here in South Africa but it it most certainly a beauty. The Genius has generous reach numbers across the size curve with good standover, stack and a geo-adjust flip-chip. Did somebody say mullet?

A remote suspension adjust system transforms the bike from a fully locked out setup (front and rear), into a 110mm rear travel with open fork setup and finally into a 150mm (front and rear) mode. In the 110mm rear setting the bike rides slightly higher in its travel with the BB marginally raised and a slightly more progressive feel. This technology unleashes the many personality types of the bike (Fully rigid, Down-country and Enduro) and is perhaps, the fundamental advantage the Genius. The proprietary rear shock also features an external ‘ramp control’ lever which gives the bike a more linear rear or more progressive rear. This enables you to fine-tune the ride to suit the specific section of trail you are on.

Scott is well known for producing incredibly light bikes and the Genius is no exception. The ‘over the counter’ Tune 900 edition (our test bike was a slightly custom version) weighs in at a remarkable 12.40kgs. The frame and shock, including mounting hardware, is a featherweight 2,249grams. This is one of the lightest in class. Regarding wheelsize, a flip-chip on the top shock mount gives you the ability to run either 27.5″ or 29″ wheels with more or less a constant BB height. Coincidentally, this flip-chip also means the bike will easily accommodate a split wheel size setup of 29″ front and 27.5″ rear which is a real futureproof benefit. The suspension layup is what Scott has coined a Virtual Four Link Design with pivots and linkages optimally placed for pedaling efficiency, braking response, small bump sensitivity, mid-stroke support, and a controlled deep stroke. The idea was to design a bike with ride characteristics that appeal to XC riders and trail shredders alike whilst combining well with the Twinloc system.


  • Fork: 88psi with 6 clicks of low speed compression
  • Fork rebound: 8 clicks from closed
  • Shock: 205psi
  • Shock rebound: 7 clicks from closed
  • Front tire pressure: 22psi
  • Rear tire pressure: 28psi


Descending: Whilst the Genius is a shredder, I wouldn’t classify it as a “big hit drop your heels and smash it” bike. For Giba Gorge, Sabie, Karkloof or Helderberg Trails the Genius will handle just about all the gnarly lines there are – with ease. The BB is low though – so you want to make sure you are running the right psi, sag and spacer setup to avoid pedal strikes. You really will get the best performance out of this bike by playing around with that external ramp control on the rear shock. On smooth trails with lots of jumps and berms I ran the bike in the more progressive setting which helps with pop on the big jumps and to prevent wallow through turns. On straight line square edge rocky trails, the linear setting naturally works best. Don’t just set it and forget it. Play around with the settings and keep trying new stuff. It’s like a new iPhone, you don’t spend all that money just to make calls and send texts – the technology is there to improve the ride experience and with this bike in particular, you really will improve your ride with a bit of tinkering. Despite there being no bearings in the top shock eyelet the small bump is very very good. Overall, in ‘Descend’ mode, the ride is pretty liner with good square edge rollover for a 150mm bike.

The rather linear descend setting delivers a calm and planted feel through rough trails.

Cornering: So this is where the low BB and generous reach numbers put you into a good posture to nail turns. Couple all of that with some super supple suspension, great traction and – “voilà!” – you are dropping your mates. I especially liked the super agile feel of the bike in corkscrew sections, where you are hopping from left turn to right turn and back again. The bike is intuitive and does exactly what you are wanting it to, with minimal body language. This is really the sign of a good bike – it becomes an extension of your body – and this is something I don’t feel with every bike I test.

Technical ability: Without the external compression adjust on the shock you want to make sure you get your shock air pressure, tokens and rebound setup just right. I was slamming pedals a bit through some technical sections until I got things dialed in. With chainstays under 440mm they are firmly in the ‘play / agile’ range and it’s noticeable through the technical stuff, in corners and when jumping. The Genius is a light bike – so much so that if you do run into a technical section a little too fast, it’s super easy to scrub speed, correct the line and get through it unscathed.

The Genius has an intuitive nature on the trails.

Climbing: On smooth transitions using the full lockout mode the bike moves swiftly. When locked out, the bike is pretty much a hardtail, delivering great efficiency. In the 110mm rear mode – or what Scott call ‘Traction control’ – the Genius is as efficient as a down-country bike – and it climbs very well.


It was around 10 years ago when I first spent time on the Cannondale Jekyll which is a similar concept to the Scott Genius, in terms of the travel adjust and lockout modes of the rear shock that is. There is also the Canyon Strive which plays in this multiple travel / multiple personality space, but I haven’t ridden the Strive, yet. Ever since those rides on the Jekyll I have loved the on the fly travel adjust as it significantly broadens the spectrum of trail that a bike can rally. There is obviously extra cabling around with these bikes and that might turn some away. On this Genius, the cabling is well concealed. I can see why the Genius is a popular choice for EWS privateers – its does everything so well. I can also see that in SA with a 150mm fork it will do really well on all of the Enduro tracks. This bike also suits riders in SA who are perhaps moving away from marathon racing and are looking for a do it all bike that they can explore technical trails on, hit that gnarly line they have been scoping and boost the doubles.

The Genius is a very good option for riders moving away from marathon racing and just want to ride and have fun.
