Replacement Rotor ?

Craig Brossman said:

Just bent my Avid 160mm rotor, I can get a Diatech for $15 from Nashbar,
or an Avid for $35. This is the first rotor I've replaced (it is badly
bent ... this time), anyone unhappy with the a lesser name for rotor
replacement?

Watch out! I've used "non brand" rotors before and always found their
specs to be just slightly off. If your using mechs it's probably not a
problem but my hydros rubbed terribly. Stuck a true Hayes roto on, and
the problem went away.

You get what you pay for.

Why would mechs have greater tolerance than a hydro system?

You can adjust the calipers. So if a rotor was cut just slightly
thicker than spec, a turn of the dial and the rubbing stops.

You can't adjust hydros? That seems weird.

Can I assume you mean thickness when you say the specs are off?
Unless they are terribly thick, I can't imagine that being a problem
with Avid Mechs.

Aside from shimming the rotors, loosening the bolts, and repositioning
the brake, no. Remember, mechs are cable actuated and hydros use
hydrolic pressure from oil in a closed system (at least that's how it
was explained to me). Although, I think I read that Hope has a new
model that does have some caliper adjustment. Avid Juicy's and the new
Hayes model just adjust for modulation.

Thickness wouldn't be a problem with mechs as I stated in the thread
with Monique. However, if the diameter was off, that could be a
potential problem. All things considered and if I had mechs (though I
don't) I would be a cheapskate and go against my true beliefs. Worst
case scnario is that if you buy them from Nashbar, you could always
return them if there was a problem.

You should be fine with the lesser brand. The Diatechs have a little more
metal in them. On long descents can really stink up the pads.

I guess I don't care too much, especially if it adds a little more
durability to it.
I guess for $15 I can try it out, If I don't like it it can be a spare.

Theres another band worth trying since your at it AZTEC
from Delta.

You can adjust the calipers. So if a rotor was cut just slightly
thicker
than spec, a turn of the dial and the rubbing stops.

You can't adjust hydros? That seems weird.

Aside from shimming the rotors, loosening the bolts, and repositioning
the brake, no. Remember, mechs are cable actuated and hydros use
hydrolic pressure from oil in a closed system (at least that's how it
was explained to me). Although, I think I read that Hope has a new
model that does have some caliper adjustment. Avid Juicy's and the new
Hayes model just adjust for modulation.

Hydraulic open-system brakes don't have any adjustment for the rotor
thickness because they don't need it. They compensate for rotor
thickness automatically. If your brake continued to rub after a few
squeezes of the brake lever, you simply have too much fluid in the
system. A properly set up brake should accomodate the extra thickness
of the Aztec rotor with no problem.
