It comes complete with a Manitou Markhor air suspension fork, a single chainring 11-speed Shimano drivetrain, and reliable Shimano hydraulic disc brakes. This bike is perfectly suited for navigating both rugged trails and the city landscape.

With more than five decades of design and manufacturing experience, the BIG.NINE 400 exemplifies the core of our international business. As a top-selling model, the 400 incorporates our well-regarded double-butted aluminum frame, a 100mm Manitou air suspension fork, an incredibly smooth and highly dependable Shimano 11-speed drivetrain, and easy-to-modulate yet powerful Shimano hydraulic disc brakes.

Mountain biking is one of the most varied cycling disciplines, and arguably the most demanding when it comes to equipment. While full suspension bikes deliver impressive characteristics, the classic hardtail endures as a pure and effective tool. Our 29er wheel-equipped BIG.NINE range offers both carbon and aluminum constructions, along with diverse geometry choices. The refreshed CF carbon and LITE aluminum-framed BIG.NINE models feature modern geometry with improved standover clearance and handling stability, designed to better tackle the tough race tracks of today. Additionally, downcountry-ready TR options provide increased fork travel, aggressive tires, and dropper posts. The BIG.NINE TFS and SPEED models feature a more relaxed geometry, ensuring a comfortable, upright riding position. Our classic hardtails are foundational to our product lineup, showcasing the deep wealth of experience and knowledge gained from over half a century of bike manufacturing. The BIG.NINE range represents the symbiosis between cutting-edge frame technology, meticulous attention to detail, and the craftsmanship 'Made in Taiwan' symbolises.

Could be good
Size: Powder Poli Ox - Pack of 6
I cleaned my RV very thorough from top to bottom before even starting the process with the Poli Glow system. Here's what I learned despite videos and lots of reading reviews. 1. Must be very clean and clear of anything you dont want to stick and show on your final outcome. 2. It takes more coats than you think it would (after 3 coats) it was still really streaky and I was starting to regret using Poli Glow. I ended around 7-8 coats and my rig had no major oxidation at all. 3. As one reviewer said, use a clean microfiber cloth v the applicator that comes with it, I found much better results with no lines. 4. Dont go to heavy on the coating, the instructions say this, but I went super light and it can be very easy to get lines with heavier application. 5. Dont look at your work after 3 coats, you will feel deflated, just keep going for at least 6 coats and then look at your work. 6. Only do small areas and look out for drips and lines, you need to get them out right away. 7. I did not use the Poli Ox, I was able to get any oxidation out with just the Poli Prep 8. Going up and down a ladder for hours sucks! 9. I hope it will come off in the next couple of years when I plan to replace the decals. Honestly, thats my biggest fear is how hard it will be to remove when the time comes. 10. After a scary start, I will say it did turn out pretty nice, was it easy, nope, would I do it again? Not sure, I need some time for my back to heal up! If you do choose Poli Glow know there are other options that maybe a better way to go such as wet sanding etc. Poli Glow is pretty good, but it can be pretty bad also if the surface is not cleaned and the Poli Glow applied correctly.

Good but DO NOT USE APPLICATOR MITT
Size: Powder Poli Ox - Pack of 6, Size: Powder Poli Ox - Pack of 6
The poli-ox worked well, just know that it will require several applications to remove old buildup and oxidation. once you are done, the paint will still look oxidized, but once you put the sealer on, the color will be deep and shiny. The sealer itself is supposed to be enough for a much bigger RV than we used it for. (17') We used 3/4 of a bottle for 1 side, due to the fact that we would remove and start over because it left ridges like a brush in paint. On the second side of the RV, we scrapped using the Mitt, and low and behold, using a microfiber towel to apply solved all of the issues. No more ridges and the remaining 1/4 of the bottle was enough to apply 5 coats. The mitt also wastes a LOT of product. So be warned use a Microfiber towel (that has been previously washed) and it will save you a LOT of time, money and angst.
