I can't believe nobody on here has brought this up yet, but Shimano's new wheels 9100 DuraAce C40 and C60 clinchers were supposed to be 37x24 and 60x24mm, but they were released in Asia with the old specs C35 and C50 rims...and they ninja edited their website to the old specs as if nobody would notice?! People who have bought these wheels are super pissed, and I don't blame them. That's really lame of Shimano and I lost some respect for them over this.

It might be asian fit version.

Seems there's just a lot of confusion as to what's being changed for the new 9100 series. Best I can tell is there's some new rims coming with new spec's but only for disc brake and tubular versions. Seems the clincher versions with an aluminum braking surface are the old 20.8/17 narrow designs. The new 28mm wide tubeless wheels look nice but seem a bit heavy compared to others out there.

Next you'll be telling people that Shimano started gluing their cranks together instead of welding starting with DA9000.

hatcha23

There's no confusion. Shimano secretly changed C40 and C60 spec sheet after customers complained without announcement. Shimano tried to cover up its fault obviously.

TimothyH

I think the OP is right.

The Shimano website lists the 9100 C60 clincher at 22.4mm wide x 50mm tall and the 9100 C40 clincher at 20.8mm wide x 35mm tallThe reviews I read however, going back to last June, said that they were going to be 60mm and 40mm respectively and were to be 28mm wide. The reviews are still out there, presumably quoting from Shimano press releases...Shame on Shimano if it is true.

Has anyone taken delivery of these wheels yet? I mean is their proof that Shimano is shipping wheelsets named 'C60' with 50mm tall rims? Couldn't this all be an error on their website?

topflightpro

This popped up on the WW forum a few days ago. A guy received his wheels and was surprised they did not match reported specs.

joejack951

From a trusted source? And clearly marked as C60's? Do you have a link? A quick Google search didn't find the thread.

TimothyH

I purchased Dura-Ace C40 Clincher (WH9100-CL) but my C40s rims are same as C35 ?? - Weight Weenies

Definitely worth reading.

Wow that sucks. I'm a Shimano guy, but this is kind of outrageous...

San Pedro

Seems like those weren't reviews, but previews. Probably, there were some problems so Shimano stuck with the old design. Doesn't seem like there is any evidence that they actually put them up for sale using false information.

Edit:
After reading WW forum, looks like I was wrong, and Shimano did have a major screw up.

TimothyH

It doesn't surprise me.

Volkswagen falsifying tests, knowingly selling cars that don't pass the test and lying to their customers...

Wells Fargo creating bank accounts without customer permission, playing games with people's credit scores, executive management lying that they had nothing to do with it and blaming the workers...

Takata orders technicians to destroy test results after seven people die from their faulty air bags...

The list goes on and on and on.

Charity demands that we wait to hear what Shimano has to say. Maybe they will do the right thing but I would not be surprised if they did this on purpose.

There are some very good corporations out there but many individuals knowingly wreck people's lives in order to make more money. These companies really need to go out of business and the people responsible need to go to prison.

I'm actually really disappointed because I was looking forward to perhaps buying a set of the C40s, but not anymore. It's also interesting that the cycling "news" and media is so industry and advertising driven compared to regular news that nothing will probably ever be said about this, especially when it involves such a powerhouse in the industry like Shimano.

TimothyH

I was thinking the same thing.

I wonder if the websites which parroted the press releases for the new 9100 groupset back in July will say anything about this.

hatcha23

Tubular version's dimensions are correct.
Only Clinchers are fault.

Silvercivic27

Prob not because they prob get advertising money's from Shimano or one of their brands like Pearl Izumi, Lazer, etc.

hatcha23

I am a lucky who purchased C40 clincher and found out that their dimensions are incorrect. I am also owner of that thread on WW forum.

I am a big fan of Shimano since all of my road bikes equipped Shimano groupsets.
I am very disappointed with Shimano cos I had been looking forward to C40 CL since Shimano launched their spec.
When C40 CL wheels are available in my country, I purchased them immediately. I was curious when I put my Conti 4000sII 25mm on their rim (It looks like narrow rims.) and found out after first ride that something might be wrong. Then I removed tyres and measured their rims and started a thread on WW forum.



Since Shimano distributor in Thailand informed Shimano headquarter about this issue 20 days ago, there's still no response from Shimano HQ.

Now I'm waiting and see what DA WH-R9100 clinchers' dimension come out in EU and US.

bikebreak

If you want wide rims, a similar and probably superior wheel is the newer Easton EC90 aero 55mm or EC90SL 38mm. Nominally 28mm wide, bulges out to 29+ in the middle, tubeless and disc option.
My EC90 aero set is very, very fast.

dvdslw

I'll second that, I love my EC90SL's! They also have one of the only Certified Road Tubeless Carbon rims available with no need for rim tape to seal them up. As for Shimano, they make some of the best products out there and will continue to do so. Its possible that upon testing their newly designed rims they noticed a pattern of reliability that didn't meet their standards, in which case they would postpone and/or cancel their release. I've seen it happen with several products over the years including the Fizik 00 seatpost which was set to release two years ago but received a redesign, a slight increase in weight, and finally released about 6 months ago. Another product was the Corima/Hutchinson Tubeless Carbon rims that were highly anticipated being the first true deep tubeless carbon wheelset back about three years ago but were never released to the public even after all the hype and advertising.

Anyone interested in the EC90SL's or Aero 55's should check out Nashbar, they often have a 20% +/- sale which makes them a bargain. They have the 38's and 55's in both rim brake and disc.

Jiggle

Shimano sure has flubbed this 9100 release.

hatcha23

Finally, I've got a statement from Shimano.

They just apologise for discrepancy of product spec between original plan and actual product.

That's all.....WTH

TimothyH

It's not a flub or a mistake or an oversight.

It is intentional fraud. People need to go to jail.

Intentional fraud? Much more likely to be what @San Pedro suggested -- they encountered some unexpected problem with the rim-brake version, so they punted. A bummer for customers and for them, and they look to be handling it badly.

Probably, they decided that it would be better to make the change than to have people wreck or whatever. They know full well that they've put an old design back on the market, that it will not sell well, and those expecting what they promised are going to go another way. Those who purchased already should return them.

hatcha23

So why they didn't tell customers earlier before launched products to the market?

Before the company announce product specification or launch actual products to the market, they must be sure that their products are able to sell. However, if they encountered some unexpected problem with their products, they should revise product specification and catalogs and public the latest product spec before put them into the market.

C40 and C60 clinchers are available for sale in Thailand last month (after Christmas). I purchased it after new year holidays. And 3 weeks ago I informed them that my C40 wheel dimensions are wrong. And they took more than 20 days to response this issue.

I don't believe that Shimano not intend to fraud their customers.
