Q & A


The SDG I-Beam system has the widest range of adjustment on the market, using a single, easy-access 6mm bolt for quick and simple adjustment to ensure you find the perfect position. When coupled with a compatible saddle the I-Beam system eliminates the risk of broken or bent seat rails.

The clamp is cold forged from 6061 aluminium for maximum strength and fatigue resistance, and the tube from 2014 aluminium, whilst the smooth black anodised finish resists damage. Suitable for on and off road applications.
