The Boomerang is profiled aggressive. This makes it compatible with the plan mounted suspension systems and is well suited for suspensions with low chain stay.
High-quality materials in the upper and lower guides offer unsurpassed impact and abrasion resistance.

The lower plate is attached to the inside of the Boomerang, so that neither dirt nor can penetrate stone. This is the system clean permanently.
Wheels with standard bearings, which can be easily serviced and replaced.
Compatible with 68/73, 83 and 100 mm wide, oversize bottom bracket.
All screws and nuts are stainless steel and thus corrosion.
