Shimano DA shifter problem(10 posts)

Shimano DA shifter problemdasho
Aug 22, 2003 5:56 PM
I have always had Shimano components on my bikes and thought highly of their quality/design but now I wonder if it is an illusion. I read a post from a few days ago on this site about some people having problems with the right front shifter on Shimano Ultegra level components who then upgraded to DA thinking that would solve the problem. I had aproblem with my one year old DA (right)shifter (approx 3K) and found out it wasn't the cables or housing as some suggested but a defective shifter, according to my LBS.

If not for the LBS finding a used Ultegra shifter I would be without a bike while the shifter is sent back to Shimano for evaluation etc. I think Shimano knows this problem well and can't figure out why they didn't send a new shifter pronto to my LBS. I never had this problem with my 105s and Ultegra and question the durability of DA, especially for the cost. I never believed that saying "Campy wears in and Shimano wears out" but maybe there is something to that. Maybe Campy is no better, I don't know, but they seem a lot more appealing to me after this.

I upgraded from Ultegra to DA after an accident and, less than six months later, the DA shifter (right hand, no less) went south on me. My LBS got me a replacement quite quickly but not before I put my old banged-up Ultegra shifter back on in the mean time (time spent messing with the bike when I was simply not in the mood!). To be honest, the DA shifters do "feel" better than the Ultegra but I am not sold on their reliability. Just my two cents...

The vague nature of your complaint leaves much to the imagination. What problems were you having.

What exactly is the "right front" shifter, BTW? I'm confused...

You had 3K miles? HAd you replaced your chain?

I have 4K on my DA and it shifts as well as the day I purchased it.
Yea, I was a little vague...dasho

It was the small right shift lever that is supposed to throw the der outward towards the small cogs. It simply wouldn't engage. I was just really surprised this could happen so early with DA's reputation (and cost). Evidentally, this is a fairly common problem at least according the the post below.

a DA shifter really isn't that much more than Ultegra or 105- esp compared to a crankset, for example. Bummer you had a problem.

My front D/A shifter (left hand) failed 2 weeks ago with only about 2000 miles on it. Shifter would no longer engage and click . Luckily I was about 100 yards from a bike shop. They couldn't do anything with lever-said it wouldn't hold cable tension. I was on vacation at the time, but the shop warrantied me out a brand new shifter-I had to pay 50$ for labor tape etc. They said they avg about 1 shifter failure per week during the busy season and showed me a handful of failed levers they were sending back to Shimano.
Every manufactured item has a failure rate.MR_GRUMPY

Out of all the people that I know that use Dura Ace, only one of them had the typical Shimano failure. One other had a different problem. Both of them got their shifters replaced, no-charge. It would be interesting to know what the Campy failure rate is, compaired to the Shimano failure rate. I doubt if the manufactures will ever give that info out.

There isn't enough Campy out there at least compared to Shimano to get a good comparison. I don't think you can call Campy on the phone and talk to a rep as easily as I did with Shimano when you do have a problem. I'm just surprised a device that is at the end of it's design cycle (new 10 speed coming out) is still failing. I would think they should have de-bugged it by now.
I think it's inherent....divve
Aug 23, 2003 12:10 PM the "aging" design. When you for instance compare it to how the latest XTR STI shifts it's definitely less sure footed and precise. It's almost like downgrading to a couple of groupos lower. Perhaps the new DA will be more like XTR.
Try this, if there is a 'next time' ....coonass
