Recently released on Kickstarter, the Digit Datum offers a unique suspension platform with fewer moving parts, reduced weight, and a generous frame triangle. Learn more here…

Designed and manufactured in California by Digit Bikes, the new DATUM is a 140mm travel trail bike with a brand new suspension system. Digit claims that its all-new ANALOG suspension design matches the descending and pedaling abilities of the most respected four-bar suspension systems in the industry, all while delivering significantly reduced weight and improved reliability due to there being fewer seals, bushings, linkages, or moving parts. One interesting byproduct of the design is a massive frame triangle, which fits two water bottles or a generous frame bag.

Even more interesting, the Analog suspension system is based on the company’s unique 12″ long Integer Strut, an internally mounted shock that’s tuned to match to the frame’s leverage profile with a larger air spring and damper made to resist overheating and fading.

Based on Digit’s Kickstarter page, it’s clear they’ve put a lot of R&D into the Datum and the kinematics behind it. Right now, they’re seeking funding for this venture, with a frameset reward starting at $2,750. If funded, the bike will be produced in sizes S-XL. Find specs below.
