One of the Parts I want to keep changing Disc Lock for Tuning around my legs. It is Impression of running about 6000 km. This Works Expansion Rotor is the most expensive in the market and is positioned closer to High performance. And why do not you see it in a street. The feature of the appearance is a diagonal groove where the Edge stood deeply.
a) Durability : Running 6000 km Currently, at Gymkhana's practice and pass, I think that Brake is overworked, but wear on the Rotor surface is totally unknown by visual inspection. Moreover, scratches on the Rotor surface which are often seen elsewhere have not occurred. It seems that the special groove effectively discharges abrasion powder and foreign matter of Bad. Floating pin selected semiFloat, but there are no signs of wear. According to HP, though I thought that there is a reasonable Maintenance, I can use it without doing anything other than inspection and cleaning. Disc Pad uses DAYTONA Gold, but the remaining amount of Pad is about 4 mm at the present time (It is hardly worn? I never attacked Pad, and on the contrary it is not easy to get Attack from Pad. b) Braking property and controllability : I changed the Master cylinder from NORMAL to RadialPump considerably, but NORMAL seems to be unstable if I use it continuously, or if the power is due to insufficient Rotor rigidity somewhere I feel like running away, but that feeling has gone away and braking performance is getting better. In addition, control is full of course when full Breaking, but also delicate operation at turning became easy. . Design and texture : After all, the groove where Edge stood deeply makes a force that is not just a person. I do not see any flashy like Wave rotor, I think that design that is dedicated to functionality and performance is good. I do not like any other luxury and I like it. The finish and the outer circumference end with the clean R and the Inner plate are created by total cutting, as opposed to the cheapness of the other PRESS board Gold punching, so the texture is good together with the Bronze color Anodized Treatment is. It is a good place for Works eXpans that Rear side also becomes floating. c) sound : I think that there are not many people who evaluate sound for Disc Lock, but this Rotor has a good Sound. Sound of juice when Brake is applied. It is similar to the sound of rubbing Knife with a good grinding stone and there is something comfortable. I guess this is due to the groove where Edge stood.. Of course there is no bad squealing. d) Judder resistance : In the PremiumRACING that I used before, I sometimes vibrate with Bubu but this Works Span does not have it. Probably because the groove effectively discharges abrasion powder and Rotor's thermal deformation is small. Totally I felt that the kimo of the good workability of Works Spring was in this unique groove. When choosing Works Spanned, we were very concerned about the weight, but it is regrettable that the Specifications are not published. I calculated it myself because it can not be used. As a rough approximation, the specific gravity of the suspension steel in the Rotor volume 7. Over 93. NORMAL 5 by weight of only Rotor except Inner. 1340 g at 0 mm thickness, 5. With 5 mm thickness, 1480 g, 6. 1620 g with 0 mm thickness. If you have 2 Both Sides 5 against NORMAL. Increase 280 g with 5 mm thickness 6. It increases by 560 g at 0 mm thickness. If it gets thicker, the performance of Brake improves, but if it gets too heavy it will adversely affect the followability of Suspension and the turning property by GYRO. Even if you lighter about 2 kg with Wheel exchanged 6. About 0 mm of 0 mm. The increase of 6 kg is apparently affected, but 5. About 0 of 5 mm. If I increase 3 kg, I think that it is acceptable range 5. Select 5 mm. The Rotor outer diameter can select Φ 310 and Φ 320 but the outside diameter UP directly affects the control nature so that the main road is made to be Main and the same Φ 310 same as NORMAL is selected. This Rotor, RadialPump, Suspension, and Wheel together are now BEST pedals.
It is a very excellent Rotor that combines the performance required for HardYouth with the performance required for general roads, and it is worth more than the price.
