High-quality Euro Certified 6061 aluminum with steel inserts to withstand all the abuse a rider can hand out. The super strong, forged Double clamps are designed to match this new HT-DC collection. These Clamps are as light as Double Light Clamps from the S-Series. Still includes a free shim for fitting standard and oversized bars. No printing on the clamp but instead a high-end engraving of our D logo.
