E*THIRTEEN, Flat Tire Defender, Sector Bikes

The direct mount e*spec chainring from e*thirteen uses the M3 tooth profile with narrow-wide tooth profile, which reduces weight without affecting chain tension. Its lightweight yet durable design and minimalist aesthetics make the chainring lighter and more beautiful than its predecessor.

Helix Core e*spec Direct Mount Chainrings feature our M3 narrow-wide tooth profile, for reliable chain retention and extra long wear life.

Whether riding Light or High, Flat Tire Defender® offers Rim Protection, prevents Pinch Flats & Dent Damage for MTB Downhill & Enduro competitions!
