Titanium 420

Adaptable Trail Hardtail for 29" or 27.5" Wheels

The Ti 420 is our all-purpose trail frame, capitalizing on short chainstays and designed with more versatility than any other similar frame. Ti softens the blows and drops the weight, while 420mm chainstays ensure snappy handling. Paragon Machine Works sliding dropout inserts allow for any combination of brake mounts, axle types and gearing you can think of, from black anodized thru axle with 74mm post mounts to silver Rohloff-specific with 51mm disc tabs.

Want to try 27.5 or 27.5+? No problem! The 420 has a slightly higher-than-average bottom bracket height, allowing it to handle 27.5 wheels without bringing the bottom bracket height too low.

Is there a little detail you don’t like? Want to tweak the geometry a bit? Have a cool idea for a frame? As with all our titanium frames, customization is no problem. For an extra $300 we can edit this frame to your liking, or start completely from scratch. Contact us any time and let us know what you’re looking for. We can help you design a frame and give you an accurate timeline for how long it will take to build.
