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.

Make sure you size up!!
Size: 4X-Large, Color: B004
Allllllmost 5 stars if the sizing was correct. I’ve been on the hunt for a decent fitting pair of women’s boxer briefs. I would say these are more so boyshorts. That being said, I wanted something loose for sleeping in so I got TWO sizes up. I normally go for a 2x and got a 4x and they’re perfect fitting. So, you didn’t get what I was looking for but did end up with some decent fitting undies. So I can’t complain too much. Just not the boxer briefs I was hoping for. Super stretchy and soft. Comfortable for sleeping in.

Really comfortable, good fit
Size: 6X-Large, Color: 5 Pack(black,black,blue,blue,light Coffee)
These are very lightweight and comfortable. The material stretches freely and doesn't bind up anywhere. If you go by the size guide, they should fit perfectly neither too loose nor too tight. Would definitely recommend.

These don't work for me...
Size: Medium, Color: B005
First the good... I like the material; it's very soft, light, and stretchy. I also like the colors, but that's all I like about these boyshort panties. My main goal for panties is to have them NOT ride up into my butt crack leaving the bottoms of my butt hanging out. It's probably comfortable for some, but it drives me nuts to feel this constant need to pull them out of my butt crack and down over my butt cheeks. If I wanted my butt hanging out I'd buy thongs, LOL. The part I really don't understand, is why they make the front and the back the same width/length. I mean clearly more material would be needed in the back to fit around two round humps, right? I mean I guess unless you have what I call a pancake butt, I don't see why there shouldn't be more material on the backside of the underwear. Why is it so dang difficult to find underwear in this style to fit up over butt cheeks? If I pull them down enough to cover the bottoms of my cheeks then the waistband is sitting right at the top of my crack which is extremely annoying (then I feel this constant need to pull them up!) especially when the front is long enough to go up to my belly button!! Who are they making these underwear for??? Ladies with FLAT butts apparently. For reference, I'm 5'5" 130 lbs, hips 37", waist 27", athletic build, as in lean but with muscular glutes & quads from speed skating. Not only are they not made big enough to go up over my rump while still keeping my cheek bottoms from hanging out, but they're too long in the front cause they constantly roll up in the front. I've even tried turning them around, even though they seem to be exactly the same front to back, and they fit exactly the same, no surprise there. I may just be out of luck finding comfy boyshort panties that actually fit the way I want them to. :/

Comfy and well made

Love these! They stay in place, are soft and comfortable with just enough stretch but hold their shape. This is my 3rd order.
