The Rootdown Ti takes the tried and tested geometry of the Rootdown and pairs it with the almost magical properties of Titanium. With an incredibly high strength to weight ratio, a silky, paint-less finish and our custom CNC’d dropouts, yoke, and braces, the Rootdown Ti is an elegant beauty that is ready for the rough stuff.
Its ductility means we can create an incredibly light frame, but still maintain compliance and quality ride feel that Chromag are known for. It's also extremely resistant to corrosion, so we can show off its clean, consistent welds and natural brilliance!
The Rootdown Ti is a beast! It features an extra robust heavy-gauge front triangle and a massive 51mm downtube, yet at 4.65lbs (med), it still saves 2lbs over its steel counterpart.
The Rootdown Ti features a 12 x 148mm Boost rear end, and is compatible with tires up to 29" x 2.5 and 27.5+ up to 2.8 wheels.
Titanium is most known for it's corrosion resistance and strength to density ratio, the highest of any metallic element. It's half the weight of steel for the same tensile strength and twice as strong as aluminum alloy. In practical terms this means we can use less material (ie. thinner tubing) to achieve the same strength. Combining this with it's ductility means we can create incredibly light frames, but still maintain incredible compliance and ride feel.
Titanium is also much more resistant to fatigue and impact than aluminum alloys, and it's natural protective layer of Titanium Dioxide shields it from the elements.
A perfect balance between carbon fibre, aluminium and steel.

Head Tube Badge
Your bike is special. The head tube badge is the finishing touch so we’ve always made a point of taking the time to do something interesting with it. Our head tube badges have changed over the years and are an indication of the time each bike was made. Whether it’s a cast bronze, or polished stainless steel, water cut aluminum or a 3D CNC carving, each one represents our commitment to detail.
As 12mm through axles have proven to be solid, reliable and convenient, we have committed most of our models to utilize this format. Our 12mm dropouts are accurate and tough and feature a removable derailleur hanger with a sturdy interface for strength and reliability. All 2017 models (excluding Monk and Nice Dreams) will follow the 148mm boost spacing.
Our ‘Yokel’ design is a small machined junction on the chainstay that helps accommodate both tire clearance and chainring clearance. Our first versions were huge CNC yokes that bridged the entire front end of the chainstays. Over time we refined this to minimize weight by arranging our chainstay layout asymmetrically and reducing the yoke to a minimal size. It’s one of our most unique frame features and has been copied by other frame makers.
Chain Stay Protector
All Chromags now ship with our injection moulded chain stay protector to help keep the paint fresh and the noise low. These have an adhesive applied, but also slot for zip ties if they come unstuck years down the line, or if you want to apply it to another frame.
I wasn’t sure when I ordered it as buying a bike this expensive, un seen, seemed crazy but I’m glad I did. I’m 6’1” and the large is perfect.
The bike is so beautiful I keep it in my living room and stare at it when it’s not taking me and the dog through trails or going to the gym.
The bike is heavier than I thought it would be but all that weight is in the wheels and I only notice it when I lift it out of the truck. It’s flys on the trails, feels weightless, climbs like it’s electric, and is super easy to turn and play with. Everywhere I go it turns heads because it’s understated but striking . Not many people have ever seen a titanium mtb let alone a Chromag. It’s fun at times but people won’t shut up about how beautiful it is. Trust me I know now gtf out of the way so I can ride. I can’t say anything negative about it. It looks, rides and feels amazing and if I lost it I’d buy another. Chromag was great about the sale and those guys rule.
Loved it so much I bought my gf a Rootdown small in red. It’s crazy beautiful as well.
honestly all i can say is WOW!!!! Ive had this bike for almost 3 years now and i love it more everyday its a tough bike its proven itself time and time again all over the USA....THANK YOU CHROMAG FOR BUILDING THIS AMAZING FRAME
I have had many bikes come and go over the 30+ years I have been riding mountain bikes, but have never had a titanium frame.
Finally decided to change that, and could not be happier with the decision to get the Rootdown Ti.
This bike climbs like a billy goat, descends like a locomotive, and handles tech with ease...
Unfortunately, since getting this frame and building it up, my full suspension trail bike has been collecting dust - this bike is that capable...
Perfect geo for riding the variety of trails and conditions we typically see here in Colorado!
Many thanks to Charlie and all at Chromag for getting me sorted with this amazing ride!
Keep the shiny side up!
Love this thing. Amazed at how well the geometry eats up the trails around here in the S2S, on anything but flat ground the bike eats everything whilst still adding some hardtail zesty-ness to your favourite trails. The climbs are effortless too! A beautiful bike that will be in my shed for years to come.
Hello I ordered a Rootsdown Ti back in November 2020 and received my complete bike in January 2021, Michael the inside sales man at the Chromag shop was an amazing sales guy, took the time to answer my questions whether stupid or not, he even read my mind when he sent me pictures of my bike built up, even a picture of it being weighed, so cool I didn’t even have to ask for the pics.
It is now September and nothing has gone wrong with my bike, it is my only Mtb and I am so happy with it, the more I push the bike the more I’m impressed with its capabilities, it’s a confidence inspiring bike.
