Niner introduces the versatile ROS 9, a 4130 Cro-Mo steel frame that can be run as a single speed - using Niner's own super light BioCentric II bottom bracket - or a geared bike with a replaceable derailleur hanger. This frame is built for abuse and the downhill spec geometry makes it a blast to ride. Niner designed the ROS 9 to be a burly trail ripper with super-short chainstays and a slack head tube angle that can accommodate 120mm to 140mm travel fork. Once again, Niner's attention to detail can be seen on every aspect of this frame. The unique dropout design allows 142x12 Maxle use and accommodates a stout alloy derailleur hanger or a single speed insert for a perfectly clean look. The custom butted 4130 Cro-Mo main triangle uses size specific tubing with exceptionally clean welds and is drilled for internal dropper post routing and a proprietary MRP XCG bash guard. Other details include custom drawn S-bend chain stays and seat stays, an oversized tapered headtube and a stainless steel head badge. Essentially, the ROS 9 is the perfect all mountain hardtail machine, made to Ride Over Shit (ROS).

Save 10% on Tubeless Tire Sealant
Show Details
The wheels that you have purchased require no rim strip and include a valve stem for tubeless use. Additionally, the tires that you have selected may be used without tubes. This tubeless technology requires sealant to maintain air pressure.

Sealant helps stop many leaks and flats incurred during normal riding conditions. The solution can be used year round, even in sub freezing temperatures.
Cassette
Show Details
The Shimano XT CS-M771 10-speed cassette provides a more efficient and usable range of gears. The gears are arranged so that when you shift the front chainrings, you only have to adjust one gear in the back to 'recover' your gear. The XT cassette sprockets offer Shimano's patented Hyperglide shifting ramps and alloy carriers for great shifting and less weight. Shimano also offers a wide range of cassette choices with 11-32 for XC racers, 11-36 for all-day climbing, and 11-34 for everything in between.

Gear Range: 11-32, 11-34, or 11-36
Weight: 268 g. (11-32)
Ratio:
11-32: 11-12-14-16-18-20-22-25-28-32

Chains
Show Details
The Shimano XT CN-HG95 10-speed chain was developed specifically for MTB riding. This directional chain employs task-specific link plates to optimize front and rear shifting, and offers excellent mud shedding thanks to the special outer link plate design. A new Sil-Tec treatment on the plates allows them the freely pivot around derailleur pulleys, cogs, and chain rings with less friction. For use with 10-speed Shimano drivetrains only, will not work for road use. 283 g.

Efficiency was the key principle when designing the Shimano Dyna-Sys XT M780 SGS 10-speed rear derailleur. The derailleur was designed with a longer swing arm and a tighter spring for crisper shifting when you want it, and less 'ghost shifting' when you don't. The Dyna-Sys rear derailleur will stay in adjustment longer and deliver consistent performance with each ride.

Features
Stronger return spring for crisper shifting
Longer swing arm for quicker shifting
Less chain-slap

The Shimano XT SL-M780-10 Rapidfire shifters easily convert to either a double or triple crankset mode with the simple turn of a screw on the left shifter. Unique 2-way cable release accommodates individual riding styles or shifting (index finger or thumb.) The upper lever still performs the same function, but now swings both ways. Pull it with your finger or push it with your thumb. The fastening clamp offers variable positioning, allowing you to set up your cockpit just the way you'd like it. The optical gear display floats above the handlebar, or it can be removed completely. Shimano SIS-SP41 outer housing and coated stainless steel cable provide super smooth shifting. Includes front and rear shifters.

Brakes
Show Details
This pre-bled brake system is ready to install with Shimano XT M785 Servo Wave levers, hydraulic lines, and M785 disc calipers. The XT M785 disc brake levers offer improved ergonomics, quicker engagement, and 20% more stopping power. Separate reach adjustment and free stroke adjustment allow you to customize levers for hand size and comfort. The XT M785 disc brake calipers get upgraded with Shimano's Ice technology, featuring radiator backed metal pads and oversized 22mm ceramic pistons. Sold as front or rear. Rotors not included.

Features
  • Easy to tune ergonomics
  • Ice Technolgy Radiator pads
  • Pre-bled and ready to install


Hint for breaking-in: New disc brake pads require a certain break-in period in order to provide the full brake power. The following procedure has proved oneself: drag braking on a downhill until the brake power noticeably increases. Then let the brake rotor cool out. Afterwards do 20 full stops braking from a medium speed. Attention: the rotors get very hot, do not touch them!
