Trek Rail 9.9 CX Race Gen 4 Full Suspension Electric Mountain Bike 2023

The Rail 9.9 CXR is a race-ready long-travel e-bike that's ready to accelerate to the full right off the the starting line. It features Trek's best carbon frame, smooth RockShox suspension and top-tier Shimano XTR drivetrain. But the real show stealer on this powerhouse is the limited-edition Bosch Performance Line CXR motor that accelerates faster and offers sustained power for ripping through rock gardens without pedalling. It's equipped with an extra-long range battery and smart system, plus the new Mini Remote and System Controller display that sits flush with the top tube and pairs with the eBike Flow app to give you activity tracking, navigation and Bluetooth connectivity.

It's right for you if...

You want seriously fast acceleration and the best long-travel e-MTB you can find. Components matter to you, and you want the most adjustability, smoothest performance, longest range and most high-tech assist you can get. You love customisation and want all of the cool features of Bosch's smart system.

The tech you get

An upgraded OCLV Mountain Carbon frame with longer reach and oversized head tube and seat tube for maximum strength. An extra-long-range 750 Wh battery, ultra-adjustable RockShox ZEB Ultimate fork, RockShox Super Deluxe Ultimate Thru Shaft shock, ultra-responsive Shimano XTR 1x12 drivetrain and burly but light carbon wheels. Bosch's new limited-edition Performance Line CXR motor with faster acceleration and extended boost, a new Mini Remote, and Bluetooth® System Controller display that's integrated into the top tube.

Why you'll love it

  • Bosch's limited-edition CXR motor gives you more power out of the gate and keeps it sustained for ripping through rock gardens when you can't pedal
  • The new System Controller shows your currently-selected assist level and remaining battery level. Its neatly integrated into the top tube for maximum protection and a sleek look
  • Bosch’s new smart system gives you all the same power and responsiveness with a new discrete Mini Remote that’s streamlined with just the controls you need at your fingertips to toggle through assist levels or change to walk mode
  • TyreWiz and AirWiz let you confirm that your tyres, fork and shock are at the right pressure at a glance. No more getting the pump or gauge out just to check
  • The new frame is extra stout with a 34.9 mm seat tube to accommodate more robust dropper posts, and an oversized head tube that works with burly e-MTB-optimised forks for less flex and more precise steering

The final word

Rail 9.9 CXR is all about power. It combines top-shelf tech with Bosch's ultra-fast accelerating, limited-edition, Performance Line CXR motor for cruising out of corners at top speed, and their biggest battery possible to power you, lap after lap. RockShox's best enduro fork, the super-refined shifting of XTR, an updated frame and AirWiz pressure monitoring come together to make it the full package for e-MTB racing.

AS GOOD AS ANY OTHER, WORKS GREAT
Size: 36 sqft, Size: 36 sqft
Used this in my 17 RAM 1500. This stuff works great, just as good as S...ss brand that is also sold on here. Same thickness and same tackiness. And this stuff sticks like crazy, once its laid down and rolled onto the surface, it is hard to remove, so I am pretty sure it will stay where I installed it. It is great value, one box was enough to do the whole roof of the truck with a little left over for small spots. I think it took a total of 2.5 boxes to do my whole crew cab, roof, floor and back wall and most of the firewall, and I also added a layer of their .25" foam. I do notice a difference in less outside noise, from wind and road. I will be doing my wife car soon, and this is the product I will be using again, I recommend this.

Awesome, inexpensive alternative to name-brands!
Size: 36 sqft
Awesome. Stuck well with alcohol prep and time to let liquid flash-off. Very consistent, piece to piece. Backing peeled easily when desired. Compared to Amazon Basics, the butyl seemed a little thicker (infinitesimally) and stickier, foil was less thick than Amazon Basics. Very good value. Started with my nice car, but after completing project, sound dampened all cars in the immediate family it made such a noticeable difference in sound level and quality of music from soeakers. Recommended!
