Justin Seem like pretty good rotors. Only been for a couple of rides with them now, but no complaints.
Li larger, mid-range rotor for better braking compared to the 160mm.
Keith Solid stopping power, no noticeable fade. Does the job
Ryan Upgraded as the stock Shimano rotors were "resin only" and my new pads are metal. Rotors look and feel great
Robert So shiny
Mr Ballard These are fantastic rotors for the price. I'd buy them again.
Alan the mouse Great upgrade from stock 160 front rotor on budget Specialized mtb. Much better performance and feel.
paul Shimano rotors, what is there to say? They just work well, nothing fancy but they haul in the bike just fine.
David Noticeable power upgrade over the original 280mm rotor.
Mr Fody No frills, functional rotor.
Mr Deang Rotors are great, no issues, good quality
Andrew C Genuine shimano are my go to replacement rotor. Never had one overheat and lasts a long time.
Darrell Bought these before great braking quality and wear rate.
Mr Haworth Basic but attractive and functional disc. Not as good as the ice tech range, but more than adequate for 90% of your riding on road or mountain.
Mr towers Tou wouldn't go wrong with these. I brought them for a cheap hardtail, good price, good feel, all round good rotor for the price.
Mr Case Lovely rotors. Complete with fixing screws. Ran completely true.
Dr Jackson Great price and perfectly functional. Not sure why you'd need a different one
Mr Gibson Usual shimano quality, sheds mud much better than the standard discs I had .
Mr Griffiths Great rotor, feels like quality and stopping power combined with my SLX brakes is excellent
Mr Newton Have tried aftermarket discs in the past but returned to buying genuine Shimano as they seem to perform better and last longer. They are certainly deburred better than others I've used and I suspect they are made from a better quality steel. Good price and excellent service from Merlin as usual.
Mr Graham These were fitted in a few minutes and work perfectly with the new XT Brakes I fitted. Very quiet and efficient. They stop you on a sixpence.
gonetothehills Light weight, good looking and well finished.
Mr Marshall Great rotors, plenty of holes for air to cool them down, look cool and came all boxed up nicely so that they are completely straight.
Jay Aston These actually look better than the picture! Bought for my singlespeed bike, they look good and work very well! As usual, excellent service from Merlin
Mr Mason You won't go far wrong with this rotor.
Mr Duncan Great piece of kit, at a great price.
Mr Wilson Usual Shimano quality. Easily fitted and it works!
Mr Ahlstedt Very nice service again rotors came in the same box well packaged, got to fully bed everything in, but the will prove to be great.
Mr Macfarquhar As ever merlin always gives great products at great prices and always gives good service and delivery
Mr Nessling Excellemt stopping power when mated to kevlar pads.
Rich Bowman Great - nice, light and worked a charm in the recent mud and slop. Can't go wrong with these.
Mr de Vries good quality at an affordable price
Mr Fletcher Opted for the 160mm rotors for my first disc brake set up and work fine.
Mr Robinson It's a 6 bolt rotor...I'm no Steve Peat...it does just fine for me and stops me when I pull my brake lever. Just what you need really. Ordered with an XT cassette, chain, PRO II hubs and wheelset as I had centre lock rotors on my old wheels. Thanks Merlin for being there !
Lawrence Simple rotors, work perfectly and easy to set up.
Mr Stephens Has done what its meant to do do with no problems
Mr Harper Overall easy to fit and good price
