RENNEN has specially developed a tooth profile that allows you to manipulate the size of an existing tooth. This allows you to develop a little more difficult or a little easier depending on your needs. Changing your gear by tooth fraction is now possible.

THE BENEFITS: A wider selection of gear, adjustments of the gear without changing the rear sprocket, without changing your chain length and without changing your rear wheelbase and saving time of gear change at the last minute before the race.

RENNEN DECIMAL RATIOS GUIDE

The decimal gear is made by a slight change in circumference so that it affects the deployment and / or sensation of a gear ratio configuration without changing the number of teeth in the gear.

For example, if you drive with a 44 x 16 and you want to lower your gear a little and the 43 x 16 is too easy. With the decimal gear you can have intermediate teeth, such as 43.7 or 43.2.
