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.

* We hand ream PF92 BB shells carefully to a high tolerance and BB cup dimensions from different manufacturers vary. We follow SRAM-Dub specifications and SRAM BB cups are our first recommendation for the most accurate fit. If there is a specific BB/Crank combo you wish to fit to your frame, we can assist in evaluating the fit and even potentially ream and fit the BB for your new frame.

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.
