It might be alien to some but 29+ wheels are a real thing, especially now that you can get tires with serious tread, like a Maxxis Minion 3.0.
The Arcturian started off as an experiment…to see if it could really work. 29+ bikes have been growing in popularity, due to their ability to carry momentum and offer a soft ride when things get rough, even with a bunch of gear strapped on. The big wheels are great for long trips and adventure riding where you’re mixing up road surfaces with sections of trail. But could they also deliver as a real-deal trail bike for proper technical riding? The answer is yes. The Arcturian - a bike with our most progressive dimensions and angles, corrected for the gargantuan diameter of 29+ tires.
Gravel roads with cross ditches and log piles? Mountain passes with ridge traverses and winding descents? Technical climbs with a healthy scattering or slippery roots and edgy rocks? Descents that slab and chunk their way to the valley floor? The Arcturian is ready.

Almost all Chromag frames are made from quality 4130 chromoly steel tubing. Chromoly is an abbreviation for chromium-molybdenum indicating the materials that the steel is alloyed with.
The added chromium helps increase the steels hardenability and also provide some corrosion resistance.
The molybdenum helps to increase the toughness of the steel.
It has a high tensile strength but is also malleable which is what gives our frames their notorious ride quality and feel. Chromoly is often used when more strength is required than that of mild carbon steel.
It falls under the AISI (American Iron & Steel Institute) 41XX designations which is where the “41” comes from. The “30” indicates it contains approximately 0.30% carbon by weight.
Chromoly is much stronger than traditional 1020 steel and it has a higher strength to weight ratio and high tensile strength, which means we can use less material and achieve a product that can withstand the abuse that riders love to throw at it.

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.
