Bombora

Description |

We're beyond stoked to now have Crust framesets available at Dismount.  Looking for a specific Crust frameset, colour or size? Want to talk builds? Contact us! We've brought in the Nor'Easter Disc to start, but are happy to help make your Crust dreams reality!

The Crust Bombora is a lightweight, steel frameset built for the roads and paths less traveled. Think of it as a sportier sibling to the Evasion. Designed around 650b (up to 2.3″ tires) or 700c (up to 48 mm), it delivers comfort, control, and classic steel resilience without compromising fun.

With a threaded 68 mm bottom bracket shell for road cranks, flat-mount disc brakes front and rear (max 180 mm/160 mm rotors), thru-axles (12×100 mm front, 12×142 mm rear), and a frame that supports rack, fender, and dynamo mounts, the Bombora adapts to nearly any adventure. Built in Taiwan with heat-treated Chromoly and TIG welds, and finished with ED-coating on most finishes, this frame is as durable as it is stylish.

Whether it’s your daily grinder, long ride companion, or weekend getaway rig, the Bombora frameset balances lightweight agility with adventure-ready functionality, making every ride an opportunity for exploration at the hands of your own build.
