Help!
Took the advice on brakes and upgraded my bb5 160mm to bb7 180 G2 rotor.
I was quite unimpressed with the bb5. Small pads wore quickly with me being a heavier rider.
They cost as much as the bb7 pads, and was tired of replacing pads several times per yer.
Lack of outer pad adjuster didn't help any. The new rotors have more slots to assist cleaning, cooling.
Bought two sets for $54 each. Front went on easily with post mount adapter.
When I took off rear caliper, noticed cable frayed under clamp. OK, got new cable & sleeves.
Problem is that the 180 rotor hits the back of the caliper slot w/o axle fully into it's slot!
The 20mm bracket that came with it should work, but it has the same offset as the 160mm bb5 adapter that was on my 2007 Piranah.
Going to larger rotor should mean more offset is provided by bracket.
Instructions with brakes were useless! don't even indicate which way the arrow on the bracket should point.
tried both ways, no noticeable difference.
