The maggies are great - except when you want change tube , once they set up good just regrind once a month or to (is it to often , riding aproximetlly 10 hours each week - half street so the rear don't take any part).
As dr.stix said - the maggies just throw you down on a manual
SO the conclusion .. V4 against trialzone.. saints wins?
ahh another thing, the max rotor size is 185 (fourplay) somebody seen broken frame due to use of 203 rotor?
