Galfer Wave Center-lock rotor: Real weight (VS 6-bolt & Shimano)

Thanks to my mate I got a chance to weight the Centerlock version of what is my go-to disc rotor the "FIXED DISC WAVE" from Galfer (I use the 6-bolt version)

A little comparison between the CL and 6-bolt as well as with Shimano's top of the line models.

i much prefer having your thoughts and commentary now.
forgoing half the bolts to save 2.5 grams is just insane

These rotors are my go to as well. The blue road pads from Galfer are also excellent and I find them better than the Shimano resin pads as well.

Thank you mate. I've been waiting for this!

your scale is polite with the greeting when turned on

Been wanting to try Galfer discs on MTB for a long time now. The reviews were by and large very positive. And yes they are way cheaper than Shimano equivalents. Prices for everything in the US is just ridiculous right now, so it's nice to have a brand that can be purchased from Europe and save some cash big time😅

The centerlock adapter from bike ahead weighs 19 grams including lockring. The 6 bolt version of the DT Swiss 240 is 10 grams heavier. So including the titanium bolts the centerlock system is only 4 grams heavier. It's still heavier, but barely.

Love the new detailed new format of videos, absolutely wonderful to watch. Its all about the details ❤

The weight diff of the CL and the 6 bolt rotor, is nearly the same as the weight of the 6 bolt rotor + 6 bolt-to-CL-adaptor. So it's free to use any version of rotor.

There is one thing, that you can go for 6 bolt version and buy adapters for centrelock, if you have centrelock type of hubs and when your rotors are done you can buy again only new 6bolt version. Weight gona be the same every time and if you decide to change the wheels, there wouldn’t be any need to buy new rotors

Well well, my standard setup was 140 mm on the front and back with Dura Ace Rotors. But with my new Galfer this is not a good Idea. In very steep hilly descents where you are forced to reduce speed in a really short time, they faded into the hell. This happened two times now with the Galfer rotors. I was scared as hell, so much I can say. The Disc need 5 Minutes to get 50% Braking Power back. I ordered now a 160er. My Systemweight is 80 kg, so the bike is very light.

I ordered a set of 160 CL online from a LBS. I wound up receiving the MTB version that looks different to the ones in the video. Weight was 114g each.

I've got the Galfer centre lock rotors on my climbing bike and they stop me as well as Shimano (on my Crit bike). I had to do a crazy stop from 75kmh on a downhill last weekend and can attest to the fact they stop very quickly when you need them.
Question - on the central lock, the 'adaptor' creates a slightly raised internal edge around the 'bolts' holes - this prevents you using a Shimano centre lock ring. Simply the Shimano ring won't lock securely. I added a Wolf lock ring, as the Galfer is a bit heavy, and this worked fine. Any comment on this raised edge and its impact on different centre lock rings?

[raphaeltiziani]

I used them, but now mainly for the rear disc as they dont last me very long and the breaking quality fades quickly with more km.

I love the idea of center-lock but if my rotor bends in the middle of nowhere, no way ill be able to pull off the wheel without regular tools. With the 6 bolt, you can at least carry a small tool to take off the rotor. Something to think about.

[chrikim]

Per your recommendation @Slayer of Grams, I bought a pair of these rotors and I can attest to their stopping power and good looks 😀

3:45 that lock ring is for 12 mm axle only I think, the other can do 15 mm too...

[sabamacx]

The Galfer MTB versions I believe are a little thicker and have much more material ~+25gr, so can absorb and dissipate a bit more braking energy. Good if you're heavier or doing big descents.

Interesting. I'm buying from R2bike, that you employ as well. I recently had to buy some disks for new wheels. Hubs required center lock. I've compared the Galfer and the Shimano XT (140 front, 160 rear). Without the center lock ring, the Galfer were significantly lighter. But when the rings were added, we get: Galfer 140mm + ring: 91.3 grams / 43.50 Euro. Shimano Rm-Mt800 140mm + ring: 94.2 / 39.50 Euro. I preferred the Shimano ones, seem to cool better due to the design. 4 Euro for 3 grams? Nope, cooling is way more important.

i used to go with 3 bolts but it was more of a fashion statement than anything. 180 asahi rotors on a cross country bike. titanium nitride coating is very grabby. no issues

[SonnyDarvish]

Interesting! I have an MTB spec'ed rim on my gravel that accepts 6-bolt and its rotors always have been heavier than center-lock.
Though, if I cared only for climbing, then yeah two 6-bolt 140 would make sense. Long and twisty descents would make my 160 RT-MT rotors scorching hot. No warps yet, but not going to risk losing weight on them life savers :)
