SHIMANOSHIMANO Centerlock Bicycle Disc Brake Rotor - SM-RT54 - S 160mm - ESMRT54SE

Easy to install and center in a 105 caliber with GRX levers. Great braking power, typical Shimano quality and performance! $20 for a rotor ain’t bad either - Great Value!

I bought a new set of wheels for my daughters gravel bike, and needed centerlock rotors for them. These were the only Shimano ones available next day, so I ordered them. They were in true, in the OEM packaging, and came with the right lockring. The pads bedded in on my daughters first ride, and stopped the bike well. Very happy with the purchase.

I bought these for a second wheelset I was building for my Cannondale Topstone, as I like to have a hardcore wheelset with aggressive gravel tires, but also like to have a second wheelset with 32mm touring tires when doing routes that are a mostly pavement and well-groomed country roads. When I buy something in this price range, I'm always a little cautious, but this was a nice surprise. These are stamped (as opposed to milled) discs, but they're a great value for the money and work very well. You can spend about 5 times this amount for high quality milled rotors, but these will stop you just about as well. While they're getting broken in, they may remove a bit more of your pads, as the cutout edges aren't as fine as a more expensive rotor, but they work really well and I'm happy with the purchase. When I can afford to drop $50+ on rotors, I probably will, but these are working just fine for me in the meantime. Good value and great performance for the budget-minded cyclist.

The disk was not machined flat after the holes were punched out of the disk by the manufacturer. I gave it 2 stars because I am hoping that eventually the high spots will were down to where my disk pads will make full contact with the disk. For this reason I cannot recommend this product. Also, the centerlock ring/nut that came with it is not the type that is shown in the picture. It requires a different tool for installation. Update - it took longer than most other disks but the disk pads and rotors did bed in and they are working well. I changed my rating to 3 stars. If the product I received actually matched the description I would have given it 4 stars.

Easy to install and aligned well with the brake calipers right off the bat. Bought it to allow air flow through wheel during cross winds (vs a solid disk). Works great.
