Theory Data Grips

The flanged version features a raised rubber lip on the inner side, which provides a tactile reference point for your hand placement and helps keep your grip secure during aggressive riding. The flangeless version offers a cleaner, more minimalist look and allows for unrestricted hand movement across the entire length of the grip.

These mushroom-style grips are primarily designed for BMX, dirt jumping, and park riding where comfort and vibration dampening are prioritized. While they can be used on other bikes, they are optimized for the specific hand positions and impact absorption needed in freestyle disciplines.

No, the Theory Data Grips come with bar ends included in the package. These are essential for protecting the ends of your handlebars and preventing the grip material from tearing during a fall.

Yes, 150mm is a standard length for most BMX and freestyle handlebars. It provides ample surface area for most riders to comfortably grip the bar without feeling cramped.

Installation is straightforward: remove your old grips, clean the handlebar surface with rubbing alcohol to remove any residue, and slide the new grips on. If they are a tight fit, a small amount of hairspray or compressed air can help them slide on easily before drying into a secure, non-slip fit.
