Shimano presumably?

But which ones (6-bolt ideally)?

I use the standard one-piece SLX discs, they’re good and don’t cost a fortune.

The Deore level discs are not supposed to be used with sintered pads so that might rule them out . SLX is a good call but there higher level that may save a few Grammes but IME SLX brakes and rotors are good enough for virtually anything .

RT66. nice and cheap. effective.

I use these

Rt99. Why did you get 6 bolt?! I have the XTR and XT rotors and there is noticeably less fade on the RT99s and I can believe that a size smaller is fine (what the marketing says). My new build is getting centrelock hubs for no other reason than to get these rotors.

Probably he has 6 bolt wheels .

That was the question Neil. If you choose 6 bolt wheels it takes ages to change rotors and you can’t buy the good ones. Sad Panda.

Cause everyone changes rotors on the reg.

That’s almost a #jambafact. Apart from when they get changed (or contaminated with oil) my rotors never come off, so the 30 seconds it takes to remove with the cordless drill and Torx bit isn’t even on the radar for things taking ages.

Bear in mind that there are wide and narrow track Shimano disc calipers.

What’s the usage?

I run the RT86 rotors on my cross/commuter bike.

I have previously run Hope lightweight saw rotors which lasted about 6 months. Then I had some A2Z Teppan Yaki, which lasted a smidge longer. Then I decided light rotors were a waste of time for my usage and just went with some Shimano ones.

I’m 75Kg and using them for daily road and offroad commuting.

Usage is on a road/gravel bike

I liked RT75s, and when they were discontinued, switched to ones which looked near identical from Hopes custom range, nothing fancy, just a concentric braking surface that covers the entire pad depth, very rarely squeal(even on original Minis) and they wear well too. Unfortunately, I didn’t take note of any part no’s, so can’t tell you what they were.

thanks

I did not know this. Different versions of the same caliper or different caliper models have different track widths?

seriously? mine are about 4 years old now…

£4 HS1/copies off eBay on most our fleet. Not many have died yet!

New Deore / SLX / XT = narrow track

Old Deore and below = wide track

Road discs = ??

New Deore / SLX / XT = narrow track

Old Deore and below = wide track

Road discs = ??

I’ll just add the new “narrow track” calipers are not really suitable for the likes of ashima airotor/kcnc razor type rotors (like that one up there^). There’s barely any contact with the vey inner track and the pad which causes uneven pad and disk wear, and as demonstrated in another thread, disc failure!

Yes. I had the Lightweight X2 floating saws, used Shimano metallic pads, and used them for daily commuting and some weekend gravel/cross rides.

anymore opinions on hope floating rotors with shimano xt brakes?

I’m in the market for some new rotors as well.. My avids G2’s (that I really like..) are getting close to needing to be replaced..

Well, if the revolution of hydrochloric disc breaks takes of as discussed on this forum, i would suggest alkaline pads….

On a more serious note, I always by the genuine shimano replacements – expensive, yet they last a long time ( plus the anodised cooling fins look good!!)

Cheers Tillydog, another reason to stay all retro!
