But if that method of adjustment is overused the angle of the brake arm is altered quite severely in the later stages of pad wear,and some people will use only that method of adjustment rather than winding the pads in with a 3mm allen key.
That's what I like about BB7's,adjustment on the road or trail is easy via the big red knobs that even my arthritic fingers don't find a problem adjusting if
they're kept lubed as I mentioned up thread.
On Promax Render such as the OP's and Avid BB5's,cable adjustment is the only method of adjusting the outside pad,with the inside static pad adjustment the same as BB7's,so at least there's tool free adjustment.
But a problem can occur if the user doesn't adjust the static inner pad in conjunction with cable adjustment of the outer and the inner pad can wear so much that the rotor can contact the caliper body as it's pushed over by the inner pad,severely compromising braking.
A situation which,in the right circumstances could prove disastrous.
It's another reason why caliper adjustment and not cable adjustment is better practice on disc brakes.
Of course TPR Spyres/Spykes shouldn't suffer from the same problem because both pads move when the cable is adjusted.
if we're talking about use on the road, it's not really an issue either way: pad wear just isn't rapid enough.
Certainly I can't imagine how far you'd have to ride before adjustment via the cable barrel was any sort of an issue.
I agree rapid pad wear in clean dry conditions isn't a problem.
However if organic* pads(standard in the TRP calipers,why is anyone's guess
) are used in mucky road conditions or MTB trails,pad wear is rapid and adjustment constant,it's the reason I use sintered pads.
*I have worn a pair of organic pads out in two rides on really mucky lanes with wash off from arable fields.
