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.
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 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.
Thanks for sharing! The more data points the better! 👍 For reference my system weigh is about 70kg fully loaded and run 140-140 and have not experience anything like that. (A lot of technical descending)
80kg systemweight doesn't seem very light. It's not heavy but that's not light. My system weight including 2 full bottles and repair kit is 66kg, that's very light and probably the more intended weight for lightweight rotors.
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.
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?
Ive been using shimano lock rings with CL rotors w/o any issues. Descended from El Teide multiple times and from other short and long climbs as well, no issues whatsoever.
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.
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
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 :)
They'll be my next pair once it's time to ditch my centrelines! As much as I love saving grams I fell in love with centrelock when I was building and working on bikes professionally. Simple, strong, one bolt, no spring washers, no loctite and no teeny torx heads to round out (or have customers round out then make it your problem during a service). In this situation the grams are worth it! I'm sorry!
I've heard some negative things about the centerlock versions of these rotors in that the rotors are fine (set up as 6-bolt) but the added on centerlock adaptor is kinda' hack and can introduce some hassles. any success stories with the centerlock version of these rotors?
i much prefer having your thoughts and commentary now.
forgoing half the bolts to save 2.5 grams is just insane
You can leave one at least^^:)
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

Love these rotors 😍😍
When are you going to get your titanium bike ready, buddy?
Yup - I use those rotors too. ❤
Love the new detailed new format of videos, absolutely wonderful to watch. Its all about the details ❤

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 have the same experience

I won’t bother with these then… system weight of 106kg 😂

but do not work nicely with all calipers because of the additional widgth.
@@fuckelonmusk I'm using with R9200 series Dura-Ace calipers, zero issues.
@@sabamacx yep, i also have them on the 9200 but had no luck with red axs / red etap or SRAM Road in general.
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.
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...

Have you ever played with the Ashima Ai2 rotors?
My mate used to ride them, he cooked them in the mountains on a ride I was on, never really felt tempted after that :)
@ yeah given the work you will give them on those long downhills…. Maybe not… very light though 😋

any success stories with the centerlock version of these rotors?
are carbon ceramic disc rotors the next thing in F1-derived super-spendy road bike technology?
Carbon rotors are nothing new for bikes. They really aren't very good, at least not yet
Carbon brakes in race cars braking advantage start over 900ºC. Under that are crap.
What pads are you using with these?
Shimano L05a pads
I run these on my MTB, they are fine but id say sram centerline x rotors are worth the extra weight
With a sharpened edge, and centered mounted handle, we would have a trail side cheese slicer. 🧀🐭
Your thoughts on Ashima rotors vs Galfer?
Galfer is better
the bolts?
I absolutely wouldn't do that but some folks will use 6 aluminium bolts 😅
I do GR5 titanium it's a bit of piece of mind 🍀
Maquina......quita directamente los cepos de los discos de freno y pon los cangrejitos de carbono....deja los discos para la mtb😂😂
but CL looks better :(
