I need a new M/C. Stock is 17mm, but it seems everyone is selling 19mm. I'll get a firmer pedal and less stroke with the 19mm, correct? Is this good or bad or personal preference?
What are the advantages/disadvantages of both? Thanks! -Jeff ----------- |

17mm m/c are indeed hard to come by. NOS pops up occasionally and they aren’t cheap when they do.
Highly recommend ATE. There are issues with some of our favorite vendors less expensive master cylinders ranging from weeping Welch plugs to using o-rings where they should be using lip seals. |
