Sram lever rebuild

Quoted message said:

Took one apart Thursday night, very easy. brake lever off, pin out the
back, shift lever assembly comes out, 'L' shaped arm comes out, shift
disc and spring come out. Easy but hard to see what really will be
wearing out on these, perhaps the arms that move the shift disc around,
maybe a spring but very simple.

They claim useful shifter life of 300,000 shifts before needing a rebuild,
making rebuilds almost irrelevant. The only downside I see to the SRAM
system is that it's a bit finnicky about setup; if you don't get it exactly
right, you end up with the situation where, when you're in the largest rear
cog in back and don't realize it, and try to shift to a larger cog (which
isn't there), it will shift back *down* to a smaller one. I rode a bike set
up by SRAM themselves that had that issue; had to dial it in a bit.

Also, no triple planned. That's a real issue for us, given how many of the
road bikes we sell have triples. SRAM doesn't seem to grasp that as a
problem yet.

What's involved in dialing it in? Setting the low limit screw exactly
right? Something else?

Perhaps they are trying to "make their bones" with the racers first,
the way Shimano did with SIS (in D-A only, sifting from the top down as
time went by)?

On most bikes, the limit adjustment isn't nearly so critical. With the SRAM,
you have to work in a perfect world... one in which there's no slop in the
pivots, or be able to anticipate what might happen in real life (when
actually riding, rather than what works on the stand).

I'm sure that's the story, but when you talk with them, they act as if they
hadn't even considered it until dealers started asking. This is unfortunate;
it's evidence that they don't fully understand the marketplace. Sure, it's
cool to build stuff for racers, but racers don't pay the bills.

I tried out a pair of SRAM levers today and I found them to be very nice.
They were much easier to use than I thought they'd be based on the
description I read about how to use them.
I really didn't think much about how to get them to work- it was a very
intuitive for me.

Not as attractive, IMO, as Campy and not as ugly as Shimano. They only
detract a little from the aesthetic that I seek.

I noted the comfort of the tires on this SRAM equipped bike I jumped on
right away.Upon dismount I took a look and learned that they were Michelin
Pro race 23. I use the 25 mm version of that tire very often, and noted that
in the past when I'd also used the 23 I found very little difference in
comfort between it and the larger size. I weigh 210 lbs.

The bike I rode was a tintanium frame made by the founder of Litespeed. It
was ugly as sin, but felt very nice. Of course it was probably the tires
that I was mostly experiencing.

Agree it is finicky, but works OK. Don't like the FD setup(no trim) at
all. Needs a looonnnggg sweep of the lever to get it onto the FD. Small
clicks ala shimano or Campag and it just keeps going to the starting
point.
Other things about it-expensive($500 Force levers), not matching
components, no hubs..I agree about triples, Compacts and 11-26 don't
solve all the gearing problems. Some will want that 30t ring and 29t
biggest cog. ALSO, being discounted already. At least shimano controls
their pricing 'pretty' well, with online and MO resellers.

BUT all in all, a nice first effort, that didn't get the lawyers at
shimano sharpening their pencils.

No flotaing top pulley, like their MTB stuff. Gotta be right on and
very suseptible to cable stretch and housing compression. NOT a big
deal tho, like any RD.

Ooh! That will be interesting. Do post about it.
