RENNEN threaded Chainring 104mm black

RENNEN threaded Chainring 104mm black

Made in the USA from a machined 7075 Aluminum, the RENNEN chainring is unique thanks to the decimal toothing made from a slight modification of the circumference of the crown. This allows you to change your gear by fraction of teeth according to your needs in relation to the BMX track on which you are going to ride. It is designed to be mounted on a 4-bolt crankset. In addition, this version incorporates the clamping screw nuts machined directly into the crown, which eliminates the use of a wrench to screw your crown to your crankset.

FEATURES :
• CNC machined 7075-T6 aluminum 
• 4 bolts mount BCD diameter 104mm
• Decimal teeth
• Thickness: NC
• Chain pitch: 3/32 "
• Weight: 102g (44.2 teeth)

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.
