PASSION PROJECT - Vital Rides the Digit Datum 24

Digit Bikes is a small manufacturer from Irvine, California. The Datum is their inaugural full-suspension trail bike that features their head-turning Analog suspension design with a strut damper hidden inside the top tube. The custom-butted aluminum frame is cut and welded in California, utilizes 140mm of rear wheel travel paired with a 150 or 160mm fork, and rolls on a mixed-wheeled setup. Eager to check out the Datum first-hand, we had the chance to meet with Digit Bikes Founder, Tim Lane, to get the rundown on his one-of-a-kind creation before taking the Datum out for a test ride. Find out what we thought!

The Analog suspension design does away with the short links often found on 4-bar suspension designs, creating a more consistent instant center that is intended to translate to more control on the trail. The design also features fewer pieces, creating a stiffer chassis with fewer opportunities to flex, creak, or fail. The lack of links and simplicity of the design is what allows the Datum frame to weigh just 6.4 pounds (2.9kg), including the strut. 

Since Digit's Integer Strut isn't constrained between two shock eyelets, the damper is much larger (longer) than a typical shock, which increases oil capacity and allows for higher flow rates. The extra space also allowed Tim to make the damper relatively simple, which improves reliability and makes the damper easier to service. The Integer Strut can be serviced without any special tools and is removed through a hole at the front of the head tube. 

Right now, Digit Bikes does not offer the option for custom-sized frames; however, riders can pick what color their frame is anodized for an additional cost. 

What do you think of the Datum's Integer strut design?

Does it pique your interest, or are you content with your current suspension layout and shock damper?
