    PM to IS adapter

    I just bought a new bike and i could certainly use your help if you dont mind. i have a 2010 RH expert, it came with the Dart3 post mount fork. I took that off and replaced with Tora 318 solo air which have an IS fork. I ordered this part but im not sure if its going to be the correct one. HOPEFULLY it is. here is the link, what do you think? my bike has the factory Tektro augils comp disc brakes

    awesome, and im assuming i can keep my 160mm disc, i've read a few forums that stated you'd have to upsize disc if you had to use IS adapter?

    nope, you have to upsize if you mount an IS caliper to a PM fork but not the other way around. you can if you want though - which is why IS forks are better than PM

    the fork is IS, the calipers were bolted directly to a PM fork, so im assuming the brakes are PM????

    my Tora which i just put on is an IS fork

    most calipers are PM nowadays. i was just illustrating the opposite situation to the one you have (which does req rotor size increase). sry for the confusion

    gotcha, this is my first time fooling with disc brakes, so i was a little confused, i got it now. though.

    any other disc brakes tips or anything would be greatly appreciated such as maintenance and break in.
