# Streamlined Bicycle Drivetrains The 'Binary Gear' Efficiently Expands Mountain Bike Gear Ratios By Rahul Kalvapalle | Published 2023-06-09 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/bicycle-drivetrains References: [kickstarter](https://www.kickstarter.com/projects/magneticdays/binary-gear-the-innovative-drivetrain-by-magneticdays/) & [magneticdays](https://www.magneticdays.com/en/binary-gear/)  MagneticDays, an Italian company that specializes in innovating new and improved [bicycle technologies](https://www.trendhunter.com/trends/bicycle-technology), has introduced a novel bicycle drivetrain that is designed to make it possible for mountain bikes to take advantage of a broader array of gear combinations than is usually possible. The 'Binary Gear' is an innovative bicycle drivetrain that makes use of a two-speed gearbox that allows for more gear ratios without having to install a front derailleur, which is something that most modern mountain bikes don't carry. This mechanical solution allows riders to access a 1:1.25 ratio by easily switching between speeds using a lever situated on the handlebar. Currently the subject of a crowdfunding campaign on [Kickstarter](https://www.trendhunter.com/trends/folding-urban-ebike), the 'Binary Gear' bicycle drivetrain can be procured for a pledge of $288.
