laurent Posted December 28, 2009 Report Share Posted December 28, 2009 Hi everyone!Can you tell me if the rockman disk brake rotor works as well as the standard avid bb7 "roundagon" rotor?With the avid bb7 of course! Because once i tried a viz sheephead, and my bb7 was really less efficient.Thanks Quote Link to comment Share on other sites More sharing options...
Ben John-Hynes Posted December 28, 2009 Report Share Posted December 28, 2009 How long did you leave the VIZ rotor before you took it off? Quote Link to comment Share on other sites More sharing options...
laurent Posted December 28, 2009 Author Report Share Posted December 28, 2009 How long did you leave the VIZ rotor before you took it off?About 3 rides of 2 hours each....So..about 6 hours of riding...A lot more time than my current avid rotor needs.

craigjames Posted December 28, 2009 Report Share Posted December 28, 2009 When i used one it was great, no issues performance wise. However, being lightweight it didn't take a lot to get it out of shape. Quote Link to comment Share on other sites More sharing options...

My bb7 took about 2 weeks to bed in properly. Quote Link to comment Share on other sites More sharing options...

My bb7 took about 2 weeks to bed in properly.Weird....Mine, takes only one ride with avid rotor, putting some water on it.BUT my question, is do the rockman rotor is efficient with bb7?Cause i'm more interested in lightweight.....but without a loss of power.

afrobot Posted December 28, 2009 Report Share Posted December 28, 2009 Though I haven't tried any lightweight rotors yet, I cannot stress enough the importance of burning in your rotors and pads. Find a long hill or pedal hard with you brake on for about 20 seconds. Let off for ten, and repeat 10-20 times. At our shop I've gotten BB5s to work almost as good as Hopes doing this.

Find a long hill or pedal hardI did do that, and since i'm living in the mountain, no need too search for a hill .I know it take a certain time, but clearly, there are out there some very efficient rotors, and les efficient rotors....That's why i'm asking if someone use a bb7 with the rockman rotor.My main issue, is not to make my viz brake working good, but to know if the rockman works as well as the original with the bb7.Cause it's the ligther rotor.

liam-pantera Posted December 28, 2009 Report Share Posted December 28, 2009 i ran a gusset r rotor on a bb7 180 once and the whole disk warped 5mm in one direction, up until that point i was really impressed with the performance but maybe you should just stick to the avid range .

liam-pantera Posted December 28, 2009 Report Share Posted December 28, 2009 thats fair enough then mate , the rock man rotor your looking at seems to have abit more to it than the gusset r rotor so hopefully it will be up to the task good luck with it Quote Link to comment Share on other sites More sharing options...
