Hi has anyone tried various clincher tires (GP4000, GP 4 season) and/or GP5000 tubeless on these? How easy is it to mount a tire on the roadside? I am looking at these for regular training and some commuting and my current Mavic wheels are impossible to get tire beads on except for very specific Mavic UST tires...any feedback would be appreciated

I would like to use these wheels as a All Road wheelset. Will 40c tires work with these rims? what is the largest tire size recommended? Thanks

Are the rims hookless, like Enve's AR disc series?

With nearly 15k miles, I am very happy with the Dura Ace 9170 C40. I’m 160lbs, along with road miles I ride light gravel, and beat the piss out of my bike. Yet the wheels remain true and show no signs of problems. At the sale price I might double down with a second pair, but I don’t even know when I’ll need them. Worth every penny vs Enve or other brands.

Dura-Ace 9170 C40 Carbon Disc
- I've used it several times
After much indecision... a couple of months reading up on many reviews, etc. I purchased the Dura-Ace 9170 C40 Carbon Disc. I have a set of Reynolds 45/65s, DT Swiss, and have owned Envy's and have to say I am extremely happy with the Dura-Ace 9170 C40 Carbon Disc wheel-set. Without any other changes I literally dropped over 10 minutes on my regular 45 mile ride. Not sure, maybe it is Shimano’s OptBal spoke system?!? but no more spongy old mattress feeling soaking up my efforts, these wheels feel super connected and responsive. The wheel depth is just right, in a strong cross wind I only had to put in minor effort maintaining course to what would have blown me into another car lane had I been riding my Envy's. My Reynolds might be a little lighter but don't feel as responsive. I can't definitively say why, but I am faster and more confident on the Dura-Ace 9170.

Sorry if the question is simple. Can these wheelsets fit 28c tires?
April 5, 2019
Hi Ronald, yes, these wheels are optimized for 23mm to 32mm tires.
August 27, 2019
Yes, they can, that's how I run them

Shimano makes great wheels, but they don't typically garner the same attention as their competition at Zipp and ENVE. While I'm not prepared to say that these are better than ENVEs 3.4 or 4.5, or Zipp's 303, I'd say that they're as good as the 302 at a better price, and with tubeless compatibility. For less than $1500, you've got to give these a look. Feel free to shoot me an email at firstname.lastname@example.org if you want to speak about these, or other wheels in detail!

What are the rider weights for wheels? Are they an "event wheelset" and not to be used for training as well?

Shimano does not have a posted rider weight that we are aware of. As a general guideline, I would not recommend this wheel to a rider weighing more than 250lbs. They are an excellent training/racing wheelset though! They're absolutely bombproof, but they'll never hold you back when you're charging for the line!

Hello there. So I have read conflicting information on these for internal/external measurements. Are they 17internal/24mm external or 24/28mm? Many reviews claim 28mm external width which would be more in line of most aero carbon wheels being produced as of late. Thanks.

Hi Charles, These are indeed 17mm internal and 24mm external. I have confirmed this with Shimano. Happy roads!
