Hi, just bought a used cross bike... looking to upgrade the avid brakes to some new shimano ones... the Shimano BR-R550 look half decent and at a good price...
I found a deal on a rear set... I was thinking of buying two rear sets.. but wanted to ask before I do something stupid... what's the difference between front and rear?
I contacted the seller of the below auction and they said that the boxes are actually labeled as front and rear but he didn't notice any obvious difference...
