How long should rotors last? I'm trying to remember how long I've had my Hope floating rotors for now but its surely been at least 4 years now. Do you guys measure rotors and replace before they're cooked? or just wait till they're obviously glazed/bent/warped? Or just time based replacement?
What 200mm rotors (that fit Dominions ~max 2.0mm) are good?

I've never worn any down to the point where they fail the thickness measurement, but I've tossed plenty due to being too bent or too contaminated.
I used SRAM HS2 and Galfer Sharks when I had Dominions. HS2s work well but will probably need some time on the stand to true them at first. Sharks are super expensive but come straight-er, hold true longer, and have more bite. I haven't tried Galfer Waves yet, but NSMB just reviewed them and they sound comparable to the HS2, maybe a tad better.

Ive been running TRP TR33 rotors all year and they've been great.
I had Trick Stuff HD rotors that are just a hair over 2mm, but couldn't get them to stop rubbing. They'd be great and silent, but one or two hard braking moments and it's be back to the constant tsk tsk tsk tsk tsk
I replace my rotors when they bent or really turn black and purple. Not often to be honest.
The Galfer shark rotors are bloody expensive here - $150 each.
I wanted to try the Lewis rotors (pretty cheap here) but at 2.3mm they won't fit Dominions.
and the rivets are still tight?
Yeah seem to be.and the rivets are still tight?
Used until they measure too thin. Not often I've bent one out of shape before then.
I put a set of the Chinsesium ZTTO 2.3mm rotors on my downhill bike and I've been impressed. I've ran them with Shiguras and XT and they've surprised me. It took a little to get them straight out of the box but since then they've been fine.
I use Chinesium Centrlines at $20 for 2 x 203mm and replace them every 6 months or so. With my Cooma Ultras.
Bulk runs at Maydena as you know is as hard on brakes as anywhere.

I bend rotors long before I wear them down. I've had really good performance out of my TRP R1C rotors for a while.
Not Canaderp. Hayes direct.
i have them on my trail bike. i like them a lot. i've got a4s on my DH bike and like those a lot too.
Got the A4 too. I'm assuming they have the same lever feel, just less powerful? To which percentage you would say ?
less power, hard to say percentage wise. i wouldn't say its significant, but none of my local trails have descents with the same elevation drop and steepness as the DH I ride. slightly more initial bite too. worth noting i'm running 203 rotors front and rear on both the a2 and a4.
Yeah. Trying to avoid shipping cost and UPS custom fees. Waiting on them on that regard.
Following!
Morning !
I have a pair of A2 brake sets in my cart. But since I'm in Canada, I was wondering which carrier you are using? Right now Canada Post is on strike, and shipments with UPS means hefty custom fees for us, members of USA's 51st state.
Let me know if a shipment with FedEx would be possible.
Regards,
Jocelyn

Andrew Major wrote an article about them on NSMB. Given the choice, he'd go A4 every time. But I don't recall him flagging a huge weakness of the A2.
I wouldn't want anything less than the A4 for a dirt rig. But for the fartbike, I'm assuming they'll be plenty powerful. I'm more interested in lever feel/shape than actual power.
But for now, getting them from the US seems like a hassle. I'll wait for boxing day, in case I can get a local deal.
Have ran them both for a while, and both on the same bike too. Same power and same lever feel (slave pistons have the same surface area, so that should come as no surprise), but less heat dissipation with the A2. Only noticeable on long descents. A2 perhaps felt a bit more bitey. Both A4 and A2 calipers leaked as well
