i have an old dyno air frame that i want to put the 990 u brakes on. i already know that i can buy the 990 mount plate for a fork that doesn't have the 990 mounts in the front, but if i want to use the u brake in the rear which 990 brake should i use with the plate, the front or the rear (is there really any difference between the 2). i was thinking maybe a combo of the 990 plate with a front 990 brake in the rear should work. please tell me what i need before i buy this stuff.
Thanks in advance
