Galfer Wave Floating V2 brake disc 6-bolt, 2.0 mm

The Galfer Wave Floating V2 brake disc is the two-piece Wave disc for 6-bolt hubs: the stainless steel braking ring floats on a black-painted steel spider, connected by coloured pins. For the V2, Galfer increased the thickness from 1.8 to 2.0 mm and redesigned the joint between ring and spider. Available in 180 and 203 mm, with pins in six colours.

Features

• Two-piece (floating): braking ring laser-cut from high-carbon stainless steel, spider made of black-painted steel
• According to Galfer, a new joint between ring and spider and an optimised structure: less weight, more strength
• 2.0 mm thick instead of 1.8 mm on the first version: according to Galfer, stiffer and more heat-stable
• Wavy edge (wave design) and anti-rust finish
• According to Galfer, powerful, progressively modulatable braking performance, quiet and low-vibration – in both wet and dry conditions
• Pins in blue, gold, green, purple, orange or red
• Manufacturer's weight: 146 g (180 mm), 174 g (203 mm)
• 6-bolt mount, includes mounting screws
• Made in Spain

Which size fits?

• 180 mm: XC, trail and enduro
• 203 mm: Enduro and downhill, also for heavier riders at the front

Whether and which adapter is needed depends on the brake mount on your fork or frame and which disc size it was built for without an adapter. Galfer offers post-mount adapters +20 mm, +23 mm, +43 mm and +63 mm. The maximum disc size is specified by the fork and frame manufacturers.

Floating or Fixed?

The Wave Floating V2 is a two-piece disc: the braking ring is attached to the steel spider with pins. The Galfer Wave Fixed 6-bolt, 2.0 mm is made from one piece, comes in sizes from 160 to 223 mm and, in 180, 200 and 203 mm, is prepared for the MG003 speed sensor magnet. So for an E-MTB with the magnet in the disc, choose the Wave Fixed.

6-bolt or Center Lock?

The Floating V2 is only available with a 6-bolt mount. For Center Lock hubs, there are the Galfer Wave Fixed Center Lock, 2.0 mm and the two-piece Galfer Shark EVO Center Lock.

Installation

• The mounting screws are included. Tighten them in a cross pattern to the torque specified by your hub or brake manufacturer.
• Keep the disc and pads free of grease; the Galfer Brake Cleaner is suitable for cleaning.
• Bedding in new discs: on a flat, safe section of path, brake multiple times from medium speed to walking pace, using each brake individually.

Frequently Asked Questions

Will the disc fit my brake?

Generally, yes. The deciding factors are the 6-bolt mount on the hub and the right adapter for the diameter. Check if your brake caliper fits 2.0 mm thick discs before changing.

Will the disc fit an e-bike?

Yes, as long as your e-bike doesn't measure speed via a magnet in the brake disc. Galfer does not list the Floating for the integrated MG003 magnet. If you need the magnet, choose the Wave Fixed 6-bolt, 2.0 mm.

203 mm instead of 200 mm – does that work?

The Floating comes in 203 mm, not 200 mm. SRAM uses 200 mm, while Shimano, Magura, and Hope use 203 mm. What matters is the right adapter: if your mount is designed for 180 mm, you need a +23 mm adapter for 203 mm.

When do I need to change the disc?

When it falls below the minimum thickness specified by the disc or brake manufacturer, is warped, or has deep grooves. Measure the thickness with a micrometer at several points in the middle of the braking surface.
