    Dura Ace C-40 advice.

    I know I'm taking chances asking about these here, but...

    I've been wanting a set of these since they were the C-35's. I know they're not much more aero than my C-24's, but I want something a little deeper without going to 50's.
    I like the look and have always wanted them.

    Does anybody have them? If so opinions please?

    NOT looking for other choices or custom advice.

    I guess technically they still are C35s, as despite originally publishing specs for them that were deeper and wider than the C35 they replaced, the C40s had the exact same rim specs as the C35. Then Shimano changed the published spec on the fly. You can read about it here.

    The published weight has also been described as... optimistic.

    As long as you know that going into it and are okay with it, they're pretty good for what they are.

    Heck their Dura Ace , I like you own the C-24's which I love and I went for the new C-40 and I love them and with all the bad press out there, they can be had cheap . As long as you good with the narrow profile your good to go.
    On a side note I have to give November Bicycle a plug, they built me up a set of Easton R90SL's with WI Hubs and man they are the bee's knee's...

    Those Shimano wheels are great. Strong, durable, great quality. I'd recommend them any time.

    I hate to break it to you, CX. But Maximum7 is correct on his spelling of "they're". Read his sentence again:

    Not their as in possessive.

    OK, I won't give it to you then.

    I've owned 3 different sets of Shimano C24 wheels, got a hold of a DA 9000 C35 set in December (new old stock, good price).

    I'd say both performance drawbacks from weight and gains from rigidity/aero are almost negligible. I like to climb and the C35s definitely don't slow me down. *Maybe* the C35s hold speed a little better going downhill. Also, no big crosswind issues. I don't regret the purchase, though. I really do like the look of the C35s.

    Also, going to the C35s, I did not need to get new tubes or use valve extenders.

    As do I. AForce AL 33 with WI front and Powertap in the rear. Only a couple hundred miles on them so far, but couldn't be happier. My Conti GP 700x25 measure out at 28, which I like.

    Thank you guys for the feedback...on the wheels.

    Custom is a big turn off, so no thanks.

    However, I do appreciate Dave's advice here too.

    I had a pair of C35s and rode them for about a year. I think any aero benefit of the slightly deeper rim (compared to the C24) is mitigated by the un-even rim width around the circumference - that HAS to chop the air up a lot. Braking is good, they stayed perfectly true. Reasonably comfortable and responsive (I rode a 300+ km fondo on them). Typical high Shimano quality. Main reason I got rid of them was I wanted a wider inner and outer rim width to run 25mm tires. The C35s "lightbulb" pretty severely with 25mm tires. For the money (and for a lot less money), I think there are better, more "modern" wheels out there.

    Today I saw a facebook post that went something like "I was driving along and I saw a woman who had some flowers for sale and a fish & chip wagon."

    I asked if they knew how much was being asked for the fish & chip wagon as I might be interested. The post was soon changed; this time with proper punctuation and sentence structure.

    It's amazing to me that people that post stuff like this actually manage to have jobs and own homes. If you can't communicate at the level of an average 6th grade kid how do you get through college and hold a job?

    It's all about knowing the right people. And not always who you know, but who you ****. I've known corporate VPs who write like that.

    Oh it was worse. I just pointed out the wagon for sale!! The rest was "I saw some lovely Spring colour's, also I saw stalls in uppermill selling flowers and a fish wagon."

    The "colours" was the British spelling on a British f/b page but the apostrophes were very selective. Why didn't stalls and flowers get one if colours got one? Huh?

    The shooting and archery forums I'm on are the worst w/ random apostrophes. Posters just throw them in every now and then, no rhyme or reason.
