  • Using the proven Shimano Centre-Lock system for excellent rigidity and security with an easy set-up
  • Rotor contact surface has been developed for excellent pad clearing and cooling which increases pad performance and life
  • Large forged alloy spider supports rotor surface, increasing rigidity and reducing weight
  • Comes complete with alloy lockring
Ben Look great, decent stopping power.
darren Superb discs, the oem pair that came with the bike suffered badly from heat warp , as soon as you rode a bit harder the discs would catch the pads ....not these! they are rock solid and gave really improved braking , took literally 10 minutes to fit , highly recommended
Mr Marais Awesome stopping power - what more can I say
Mr Pearson Superb braking especially in the wet and so easy to fit
Mr Satar It was a performance I expected from the rotor. Good grip. I use it with the SLX M7000 brake set. Very handy. I had to buy one because I couldn't afford it. That's why there's a bad rotor in the back :(
Mr Dummer An excellent product that due to light weight I prefer over the newer ice tech rotors.
Aynakol Zincir Safkan gravel bisikletler için ideal bir fiyat / performans diski. Shimano Ice-Tech Frezaa soğutma teknolojisi ani frenlemelerde keskin duruşlar sağladığı gibi güven de veriyor.
ian Replaced a non shimano rotor with these and braking has improved a lot. As yet I have no sqealing with sintered pads and saved weight. Excellent
Jeffrey Seems decent for the money and also included the cassette-style lock ring.
Mr Birkin Firstly Centrelock is great. These discs work adequately on mtb, gravel and road in all conditions.
radioactive man Very good rotor for braking power and longevity. Need to bed in and then keep clean to minimise squealing in my experience.
simon Needed a CL disc for a new set of wheels. Shimano the obvious choice and can't fault the quality. Not that cheap and not that easy to find but Merlin had stock. Bought two now and rolling with the new wheels.Good discs, recommended.
Matt Does the job well
Ross Lau I have run these on a previous bike with great performance over an extended period of time.
Centurion Cycling Club just replacing a pair of 2yr old rotors. works really well, great silent stopping power
Charles An exact replacement for the rotor I wore out, great piece of kit
Mr Hobbs Bought 140mm rotors for my road bike. Build quality typical Shimano, very good. Included center lock lock rings which was nice .
Mr Jones Does the business with the stopping, be aware if (like me) you're running 15mm-20mm Front axles and 12mm rears you may need an additional locking ring (with the external splines). The ones supplied I couldn't tighten as the end caps on my hub were interfering.
Jason Use these on my MTBs and road bike. Durable, excellent stopping power and no noise. For the price, best rotor out there in my opinion.
Mr Lefort Simply the best rotors for money. you can spend more on the RT98, but the performance isn't 50% better like the cost would imply
Andrew No issues here, light weight, good performance and does what it's meant to.
