I have never ridden SRAM and never owned Dura ace 10 speed. Every post war Tour de France has been won by Campy or Shimano dura ace (since Lance). Every recent Grand Tour has been won by either of these. Every classic has been won by these. Boonen , Pettachi, and Chipollini (did) sprint on Campy. Good enough for them, good enough for me. Pro riders seem to care very little which one they ride, because they are all good. I do believe you that Sram works excellent, just not that it is a lot better. SRAM red levers were not upgraded, just the rival and force ones, your right about that. And I do think Truvativ/Sram has a better BB bearing construction than Shimano. BTW Daniello the Luca rode (rides?) a right side Veloce lever just for the issue you mentioned (to have single gear drops only). It does show that lower quality levers don't hurt you. I do not understand how you lost races by to many up-or down shifts though, unless it is a steep uphill sprint finish.
If I were Clint I would keep the levers he is selling, and buy racing wheels or a training tool. Something that really helps you go faster.

You should ride them both they are very nice. They should they have been the only two in the main stream. Now That sram has some protour teams maybe they can win a tour. They are however winning a lto of other races. The tour is just one race. When you think that they entered the road market in 2003 that is pretty darn good.
I guess my issue is that you have not ridden it but know it is not a lot better. I will give you that a lot may be a little to strong. But it is much less expensive.
As far as upgrades Campy upgraded the entire line last year. this year they are doing it again. Are you saying that a product can not have improvements or it is not as good. Every company improves and makes changes every year. Where Sram has tweeked things Campy has done a major redesign of the BB and Cranks. Dura and Campy have gone external BB following Srams lead. Hoolow BB axel is Sram's as well.
As far as campy costing races. You jump the sprint in a 53 14 and then you want to go to the 13 but Campy lets you go to the 12 or 11. You bog down for a second and a gap is created as you bring the leg speed back up. Or you learn this flaw and then jump in the 11 and the gap is formed in the jump and you are playing catch up the whole time and run out of meters.
As far as pro tour pros go they do not care what they ride as long as teh checks cash.

The power and torque these pros are pushing is tremendous when compared to our loads. I would say that either chain would work well, but if you are racing maybe the more reliable chain is better suited for this purpose. However, recreational usage of a bike I'd imagine that a more pricey chain isn't truly needed. Forgive me if I've repeated information

I could not find my old 2007 post, but when I had SRAM Firce originally on my current bike the chain broke on me. I was not putting it under extreme load at the time, but starting from a standing stop. Unfortunately it still flipped me off the bike. I used a Shimano chain from that point forward and have never had any problems.

I'm curious if a shimano chain takes longer to wear out when compared to sram? Do you all find this to be the case?

My SRAM chain was less than a month old when it broke, so it was definitely no wear and tear on it. I have had great satisfaction with the Dura Ace chains and plan to use only those for the foreseeable future. I run a Dura Ace on my bike with SRAM Force compact crankset and SRAM 11-28 cassette, but a DA chain. It all works well together.

I don't think you can feather the shifters on the SRAM stuff like you can on the Shimano, another sticking point for some like me.

I can say that I have never broken a Sram chain. I have broken Shimano and Campy. I guess I will break a sram chain sooner or later. I just do not like the hyperglide pin that shimano uses. The sram speed link is a much better system.
I would be curious to have seen the chain you broke to see what happened.
What do you mean by feather the shifter? Front end trim Red has that and it is being spread down to force and rival.

Kent (at Motion Makers) took pictures of the chain and sent them to SRAM. One of the pins basically sheared off/loose. It was likely a fluke, but nevertheless it happened.

Cancellara's broken Sram chain was probably a fluke, too. {cue laughter from the peanut gallery}

Like one guy said "Cancelara + Climb= broken chain" Personally its Shimano or Campa chains for me. I will probably break my new Campa chain since I put it together without the guide pin, but so far so good. SRAM chain problems are widely reported but they promised the 2009 chains solved those problems. BTW, The two hardest classics (Flanders and Roubaix ) were won on Campy 11 speed, although I swear Tom Boonen must have arrived with the lowest 5 cogs clean. Would have loved to see Pozato, Boonen and Hushovd sprint for the win. Many teams using Shimano 7800 levers instead of 7900. Flecha bent his chain rings in the pivotal crash (so much for saving a couple of grams of aluminum there).

From Roadbikerider.com
"Daniel Navarro's broken chain was the second reported in a week, and it appears both were 10-speed models from SRAM. Navarro's Astana team uses SRAM components, as does Saxo Bank, which saw Fabian Cancellara break his chain on one of the Tour of Flanders' short, steep hills. According to cyclingnews.com, the day after Cancellara's mishap Saxo Bank mechanics were seen installing Dura-Ace chains on all the bikes."

I've switched to all SRAM components this year, Chains included. I've also run a mix of SRAM chain with DA cassette, SRAM Cassette with DA chain, etc. I find that mixing parts makes the system more noisy and less precise, so I've gone all SRAM now. I haven't had any issues with any SRAM chain. Most of our team is on the same setup. David Forkner is on all SRAM and is regularly putting out 1800-1900 watts in sprints, rivaling the torque pros can put on a chain. He hasn't broken one yet.
