Abbey Bike Tools are our favourite precision tool manufacturer. Designed and manufactured by a team of passionate engineers.
Here's what they have to say:
"The HAG is the last hanger tool you'll ever have to buy.
Why you need one
The derailleur hanger is the foundation for the modern drive train to work properly. With modern bikes getting as many as 12 cogs in the space that we use to put 8 it's never been more important to make sure the hanger is perfectly straight. Sadly many of the current tools just aren't capable of achieving this kind of precision.
What makes the HAG the best
We went through extra steps to make this tool half precision measuring instrument and half pry bar.
For orders outside of the UK shipping will be charged separately.
