WOLFTOOTH boom Goatlink for Shimano 10-speed + Shadow derailleurs
With this CNC milled aluminum boom can be upgraded the Shimano Shadow derailleurs + in order to go with a 40 mm or 42 mm extension pinion. With the original boom the B-bolt must be positioned to the rear derailleur to the maximum. Thereby the derailleur is drawing far back and wraps around the sprocket to a lesser extent. The boom positions the derailleur a little further down, so that the chain is better managed throughout the sprockets. The chain thus wraps around the sprocket in significantly larger scale. What increases the switching precision.
Note: The Goatlink is only with the Shimano Shadow derailleurs + standard hangers compatible!
