Echo Urban 4-bolt Booster

Description and materials
- Popular 4-bolt brake booster from Asian manufacturer Echo.
- CNC machined from a single piece of high quality 6061-T6 aluminium alloy.
- Its 4-bolt design increases stiffness considerably, improving overall braking performance.
- Furthermore, its large profile helps protect the cross-over pipe.
- Several holes machined in the booster arms help save unnecessary weight.
- Only suitable for those frames with a 95mm to 102mm spacing between mounts.
- Its 50mm vertical clearance ensures it fits 20”, 24” and 26” wheels.
- Supplied with 4 high-quality titanium bolts, as well as the spacers needed for the setup.
- Three finishes available: in anodized black, silver or red.
- Please note: the bolts supplied (M5 x 42mm) are suitable for the Echo brake clamps, so they might be too short to use with other brands’ brake clamps.
