BSC - DAG Extension

Extend the reach of your DAG (Derailleur Alignment Gauge) by 30mm with our DAG Extension.

Useful for:

• low stems where the stem is too low for the DAG to work for lever height setting
• older DAGs which did not have such a long reach - for example the Cyclus pictured - with the DAG Extension fitted it would be able to straighten a dropout on a modern frame with the increased reach

Can be daisy chained for extra reach and is compatible with other brands of Lever Height Setting tools.
