On the other hand, they admit to issue, which ALL manufactures have had in the past!
Also, i have used the 9100 and the XTR rotors on 9200 calipers and they have never caused me a single issue. The 10% larger gap is a big difference.
Have old shifters new calipers on the TT bike and it's not perfect. Road bike is perfect.
New Shimano RT-CL900 and RT-CL800 rotors
Moderator: robbosmans
This rotor in real world looks better than I initially anticipated from product shot.
1) minimal amount of slits, minimize pumping loss. That, we already know from product shot.
2) Look at 2nd picture. The black part barely curve out of the frontal shadow of the steel brake track. The heat sink looks more like rear fairing rather than a "fan blade" shape of prior Dura-Ace rotor.
3) Spiders are enclosed. It's not a square rod like SM-RT900 but rather, more like triangle rod.
4) Mounted to the wheel, this one came dead straight out of the box. Unlike my prior Shimano rotors.

Here you have many information about it from other people.

And it is not marketing, bigger space for rotors truly exists.
Trash? They're claiming half a mm of deformation after a full minute of (I assume this I what the X axis means) sustained braking. Honestly doesn't sound that bad to me.eucalyptus wrote: ↑Fri Aug 19, 2022 6:33 pmI like how they make their old rotors look like trash with graphs like that

Sample size of one, but now running a 160mm RT-CL900 on the front of my gravel bike, replacing an XTR one. It's the first Shimano rotor I've had that's almost completely true out of the box. After about 200km it hasn't warped noticeably. Pad chatter when braking hard is less than the XTR - I guess it's due to the different shape of the machined slots. Hopefully they won't descend into the usual shitshow of warping and constant trueing after 1000-1500km. Based on limited initial experience and Shimano's own data, if you trust it, I'd say they're an upgrade over XTR, and certainly previous DA. Wish they did them in 180 too.
Almost 1000km now. Still the same impression. Virtually no warping or need to true it. Sample size of one, but this particular unit is the best reasonably light road rotor I've used.RDY wrote: ↑Wed Jan 18, 2023 1:55 pmSample size of one, but now running a 160mm RT-CL900 on the front of my gravel bike, replacing an XTR one.
