rhythm_101 Posted February 25, 2006 Report Share Posted February 25, 2006 (edited) hi,i've decided to liberate my little bros bike of it's avid dick, the problem is, it's only a 165mm (on a mod) and i need a bigger rotor, like 185 maybe 203 but thats abit excessive i think anyway, i looked on CRC and they've only got this one.. adaptor in the discription it says " 74mm to 74mm post mount" now if i'm not mistakes "post mount" are the types of mounts found on manitou forks, not the IS mounts found on the ,ajority of forks (including trials forks) so all in all i'm a bit lost can someone shed some light on the situation? whether o not it will fit, and if anyones got a second had jobbie, ooooor if i could use any other make of adaptors (hayes/shimano etc) ?cheers in advance Edited February 25, 2006 by rhythm_101 Quote Link to comment Share on other sites More sharing options...
Felix Posted February 25, 2006 Report Share Posted February 25, 2006 You need an IS to PM adapter.They are available from Avid in three sizes, 160mm, 185mm and 203mm. Quote Link to comment Share on other sites More sharing options...
rhythm_101 Posted February 25, 2006 Author Report Share Posted February 25, 2006 FANQ but could i possibly use any other types of adaptors? eg shimano? Quote Link to comment Share on other sites More sharing options...
Felix Posted February 25, 2006 Report Share Posted February 25, 2006 Should work seeing that both IS and PM are standards.As long as it's for the right rotor size of course. Quote Link to comment Share on other sites More sharing options...
Joe_Elding Posted February 25, 2006 Report Share Posted February 25, 2006 Or you could whack 15mm worth of spacers under the post mount adaaptor bit to lift the caliper up a bit. Quote Link to comment Share on other sites More sharing options...
Hobnobs Posted February 25, 2006 Report Share Posted February 25, 2006 Or go on wiggle and buy the avid 185mm IS mount, for 7.99. That will work. Quote Link to comment Share on other sites More sharing options...
